What do we really know about the effectiveness of digital advertising? (thecorrespondent.com)

Great to see an article like this. This subject is almost suspiciously under-researched by journalists. There 's definitely something rotten in the promises that internet advertising has become somehow more effective. If that were true, wouldn't businesses notice? Wouldn't they spend a bigger part of their revenue on ads ? Wouldn't that return even bigger ROIs? Yet businesses spend roughly the same for over a century in ads, and it's not like the 2000s-2010s were the period of massive growth in consumer spending.

We need more of this research, please, because advertising is a huge deal for the health of the internet, despite its vilification. And it doesn't begin and end with FB+Google

Also: It would be nice if people who comment here and work for Google or FB declared their conflict of interest


>Wouldn't they spend a bigger part of their revenue on ads ? _For context, we've worked with thousands of advertisers worldwide_ They do, up to a certain extent. ROI isn't the only element to look at here, what also matters is at what max scale you can keep this ROI. Let's take e-commerce as an example scenario:

A digital channel can deliver a solid ROI (>200%) at $10K-$50K / month. Advertiser is excited, wants to scale to $500K / month. ROI drops to 110%. Woops, not as good. So what does advertiser do? Advertiser finds the max scale they can run at to maintain an acceptable level of ROI (for ex, 140%) and that is $100K / month of spend on that channel.

The interesting shift we're seeing is that historically, advertisers just went on and multiplied the number of channels, spending $10K / mo on channel 1, $50K / mo on channel 2, $500K / mo on channel 3. However, the cost of maintaining each channel and optimizing is greater than the added value. So current trend we're seeing is consolidation of this spend, and understanding that they won't be able to spend as much on ads since they still to need that 140% ROI, but only on a few channels.

As to measurement, incrementality measurement (usually two methods, ITT (intention to treat, divide your entire audience in 2 parts and show ads to only 1 of the group) or ghost ads (described below) delivers a very clean metric as to whether ad spend if bringing any sort of value and how much value it actually brings. Assuming a healthy p-value is present (aka, assuming advertiser is running enough marketing spend $ that results are significant), that's your answer to how much more you should invest on the current marketing campaigns (or it will show that you need to change your campaigns because current ones are not performing)


great insight. any source for that claim ? thks


What claim are you referring to?


Maybe the ROI numbers you qoute in reply to a long explanation about ad-spend ROI numbers being as reliable as a noth korean non-proliferatin pledges?

Also: please disclose your specific conflict of interest, presumably you have some since you appear to work in the field.


My ROI numbers there are all examples to demonstrate my point, they’re not actual values supposed to reflect any sort of reality.

As to conflict of interest, I did mention we work with a lot of advertisers but certainly not a conflict of interest, simply sharing the thought process of advertisers today. When we run incrementality tests, sometimes it shows that the campaign is not performing and then we stop the campaign.

So my comment above is not intended to mean “spend on marketing”, but rather “if you do spend on marketing today, you should make sure it actually delivers incremental value and therefore you should measure that incrementality.


I'm not sure if businesses spend roughly the same on advertising. I've experienced wildly different %'s of total spend depending on various factors.

Regarding the efficacy of online advertising, some businesses do notice but at the same time there's a larger question which is the trade-off between what online ads can achieve for different products at different stages.

Imagine a scale from "sitting in front of someone and explaining the value prop" to "an adwords ad."

If you're trying to remind someone about a brand they already know about, or attract them to a value prop that is easily explained online ads are great. If you have an unknown or hard to explain value prop you'd be better off starting elsewhere.

I agree that we need more research. Also, some suggested reading for anyone who's interested:

> advertising is a huge deal for the health of the internet, despite its vilification

This is basically tautological though. Yes, the status quo is that advertising drives the revenue that dominates most of the content and app creation that exist today. Who can say what it would be like if advertising were removed? I don't think this is easy to answer, and I'm default skeptical of research since the conflict of interest seems likely in many funding scenarios.


Not a tautology. Just insufficiently creative thinking.

Don't most of us here remember the olden days of the web? When internet advertising was a waste of time and most websites were funded from the pockets of the creators. I mean, even today that's partly common - how many bloggers and podcasters are asking for topup funding.

It's silly and wrong to think the internet would die without advertisers. Big content producers could make fairly priced single article access (don't you remember micropayments? instead we got subscriptions), and generally return commerce to the olden days when people anonymously purchased what they wanted from a shop, instead of signining away access to their bank account and email address (password collection points abound in the modern internet, deliberately or not, and everyone who encourages us to create a password is damaging the personal security).

Amateurs could use such platforms as well as advertising driven tools that are merely less effective at stalking you.

Really it's only the stalkers themselves who would be hurt by such a change.

I am, of course, delusional. But I can dream.


> don't you remember micropayments?

No? I don't think I've ever seen a working pay-per-single-article system, rather than a subscription. The amounts involved are too small, doing a payment for anything less than about a dollar isn't viable.


Honestly, I don't think it'd be possible to return to an internet without advertising, at least not in the sense of people paying for content via microtransactions or what not. Like it or not, many people now see content as 'free' by default, so their interest in paying a creator to access something is pretty much gone.

It's like the situation on smartphones with apps. Many people and companies have tried to get people to pay for them again (like Nintendo with Super Mario Run), but the audience wasn't having any of it, since they'd gotten used to 'free with in game purchases/ads' as the default. So the attempts faltered, and most went back to the exploitative models instead.


> because advertising is a huge deal for the health of the internet, despite its vilification

[citation needed]

I am of the opinion that internet would be a much saner place if advertisement was purely and simply banned.


I’m banning advertising via ublock origin and I can attest that the web indeed becomes a saner place without ads.


on ios im using a remove ads DNS thought VPN app. It is a nicer experience for sure


Then how would we be able to browse for free?


I'm confused by this, because the websites with the most value to me are those with the fewest ads. Like this one. Or the company website for a tool I bought, where I can now go download the manual as a PDF for free. Or some personal blogs I read. Even Gmail, which used to be the classic "great service in exchange for ads", I only use through IMAP clients and honestly don't even know if they show ads in the web view any more.

If you mean journalism, that's a business that has been going out of business even with ads. Advertising is just a historical implementation detail for them, like "printed on newsprint", or "tossed on my porch every morning". It does not look like a serious contender for how to make journalism profitable in the long term, any more than "teenager bicycle delivery system" will continue to be the ideal distribution mechanism for weather reports and sports scores.


The free internet can be split into two groups, websites operated for non-commercial reasons and websites operated for commercial reasons.

The group that operate under commercial reasons can also be split into two groups, those whose primary revenue is from advertisement and those whose primary revenue is from non-advertisement sources. Hacker news for example belong to the later and gain revenue from investing.

To answer the question on how would the internet exist without the subgroup of people who operate website for the commercial reasons of advertisement is difficult as each of those groups also compete with each other, but we can be pretty sure that the other groups wound increase in size.


HN has ads: startups advertising for employees. But I don't know how YC thinks of the effect of HN.


It has ads, but those are not commercial. Only indirectly.


What do you mean that the ads aren't commercial?


The companies don't pay for the ads (that's my understanding). It's not dissimilar from an artist mentioning a patron. It's more an endorsement than an ad, it's not exactly the same thing as AdWords.


If there is a medium for sharing content and communicating then it will be used. With or without monetization. The infrastructure is still funded because you pay for access and hosting. That being said, I don't believe that's going to happen. So uBlock Origin, Privacy Badger and ever more aggressive blocking it is.


I am not able to browse for free. Right now it costs me around $35 a month for access.

I'd gladly add a few dollars to have an ad-free web and I bet many people would as well.


Sometimes, the same way we eat for free. [As a rule, we don't, but we have a much greater need for food than free internet browsing.]

Othertimes, the same way we breathe air for free. [Some things are too difficult to contain.]

Still other times, the same way we drink water for free. [Some things aren't really free though they feel like it. Instead, we pay for them at another point.]


https://techcrunch.com/2019/06/11/internet-trends-report-201...

Please review page 22 to see that there has been a significant shift towards digital advertising since 2010.


i m talking about total advertising as a share of GDP[1]. The shift to digital is naturally following the eyeballs of users. Google's profits rocket while others' fall. The question is, did this shift drive increased consumer spending ?

https://www.researchgate.net/profile/Rachel_Soloveichik/publ...


But isn't digital advertising substantially cheaper than traditional ad buys (e.g. print, TV)? If clients can spend much less to reach the same number of potential customers, why is it necessary for them to spend equal to or more than a traditional ad budget?


Cheaper than TV per eyeball, typically no, minimum spend on TV is higher because of the minimum purchase (i.e. number of impacts for your demographic for a spot is typically high).

TV typically caters for the big brands who want the mass public to know about their brand/product.

Targeted advertising is starting to emerge on TV, where you basically have the digital model of targeting and ad at an individual, the cost per individual is then higher than broadcast ads.


If the ROI was higher, then they would spend more. Simple as that. But not company has done this, suggesting the ROI is not as good as was thought circa 2010.


Diminishing returns. Once your total addressable market knows about you, slamming it with ads isn’t going to help.


Explain that to the assholes who blast the same three advertisements on most TV channels 24/7


You are missing a lot of other shifts. For example, in a retail business, location is a form of marketing spend - if you rent in a high traffic area, you’ll pay more for the location, but will need less marketing dollars to attract the same customer.

Now, how does that apply to e-commerce? I don’t see the linked chart showing these changes.

There are many other structural shifts that a simple trend in a given Ads sector would show.


That's a fair question, thanks for the link.


His point is that the total spending is approximately constant (controlled for the size of the economy I presume).


> Wouldn't they spend a bigger part of their revenue on ads ?

That isn't the best question. Businesses spend stupid money on advertising in the mere hope and faith of grabbing attention. Sites like Google (the actual search engine) are really good at measuring effectiveness because their entire revenue model is built on micro-auctions measured by engagement.

The better question is: If digital advertising were so effective then why couldn't advertising customers contract to ad suppliers a percentage of their ROI for the supplied traffic?

The real answer is that a traffic impression certainly isn't a retail conversion. Those two are completely orthogonal. The hope is that increased total traffic volume suggests greater potential conversion rates, because 1% (assuming 1% of Google traffic converts on your site) of a 1,000,000 new customers from Google is a larger number than 20% of 5000 users from word of mouth marketing (assuming 20% of that higher quality traffic converts).

Unfortunately, this thinking is severely flawed, because traffic consumes resources and customer support that can be monetized as a fractional cost per user that quickly adds up. After consideration of expenses a retail site is likely still better off with the 1,000 (20% of 5,000) converted users from word of mouth marketing than the 10,000 (1% of 1,000,000) converted users from search engine traffic.

These things can be figured out decisively with precise numbers by analyzing past traffic, search engine spend, and conversion rates for any major online brand. Its just a few numbers with some applied calculus reviewing historical trends. Knowing this some business leaders see online advertising through the lens of a crack addict.

The drug addiction of online advertising for a major online brand works something like this:

1. In order to grow an online presence needs more traffic, so they increase marketing spend.

2. Marketing spend will bring traffic, but its expensive and that traffic may not buy anything. We called this dirty traffic.

3. Increased traffic means more eyeballs on the site not generating revenue, so put online advertising on the site so that those freeloaders can at least deliver some value back.

4. Nobody likes online advertising. Online advertising really repulses people, which is a hit to conversion. This hit is measurable.

5. Since conversions per capita nosedive you are pressured as a business leader to make up for the downward trajectory. Fixing the business takes time. Users take their time with purchasing decisions, which is what we called the buying cycle and this is also measurable. Click through on adds brings instant revenue at a substantially lower margin than a user purchasing anything (even really cheap crap). The hope is the difference in the immediacy of the result makes up for the reduced margin, but it won't.

6. By this point there are a couple of things going on. Traffic grows in a short term as marketing campaigns only (there are some rare exceptions) result in short term growth spikes that can dip once the campaign ends. The conversion rate drops and expenses go up. Impatience increases as the business cannot wait for the natural buying cycle to make up the difference on a macro-economic scale when the revenue from ads is instantaneous and predictable. Since ads decrease conversion need more traffic to feed the online ads to make up the difference, which means more marketing spend and further still more dirty traffic reducing the conversion rate.

Its a cycle of death to e-commerce. I can speak to this because I worked as an analyst and brand experiment engineer (A/B tests) for one of the most well known online brands of the last decade that ultimately failed due to a combination of internal conflict from management and over-spending on marketing. The brand still exists, but its now just a white label owned by its former primary competitor.


This is the best articulation I have read explaining the phenomenon. Thank you. Can I steal this ?

If only business leaders can wrap their head around recursive feedback and have the courage to account for it.


> Can I steal this ?

Absolutely.


This is basically eBay, there should be no reason for their site the be ridden with display ads, much less the massive performance hit they seem to be taking on desktop because of all the adtech junk loaded in.


Journalists and their readers rarely have the ability to break down these economic principles...and if the marketers themselves don't care, why should anyone (except the stockholders, who make less money from the company).


From the article:

> Marketers are often most successful at marketing their own marketing.

I've seen this play out at places I've worked. After raising a funding round, marketing sold the leadership on letting them burn the lion's share of it, even though launching new marketing campaigns was never on the list of reasons we initially went out to raise money.


I think that's a self-preservation tactic for many that often backfires.

Most non-marketing management people want immediate and huge results... which are both hard to quantify and impossible to get without overspending or having an insanely lucky idea that goes viral.

Naturally this leads to asking for a bigger budget and promising bigger results, then KPIs aren't met for X, Y, Z reasons, then they're forced to justify the spend, then they either get more budget or get fired and the cycle repeats. Marketing has too many intangibles, so marketers always feel a need to justify themselves out of fear of being an easy target.


I'd be nervous to work for a company where one of the co-founders isn't a marketer.

Marketing is usually one of the biggest line items for a business.

When your marketing team has little incentive to actually deliver, they're likely to ask for a ton of money only to add impressive things to their resumez, not really to deliver on their promises to the business.

If a founder is in charge of marketing, s/he's got a lot of reasons to deliver: founder's equity.


> I'd be nervous to work for a company where one of the co-founders isn't a marketer.

I'd be nervous if there were a co-founder who is a marketer (unless it's literally a marketing startup).

Take a look at some of the hottest tech companies right now (recent IPO, FAANG, pre-IPO, YC darlings). Would you be really afraid to work for a FAANG, or hot recent IPOed companies like Zoom or PagerDuty, or pre-IPO companies like Stripe or Flexport because of the (co)founders' non-marketing background?


In most industries it takes one to two years for people interested in your product to notice you and start trying out your product. And another one to two years for them to decide incorporate your product into their future business. And another year or two to generate strong profits.

So 3-6 years.


What do marketing management people want?


I mean, immediate huge results are great if they happen.

Really, they want what everyone else wants - ability to test ideas and executions before committing to a budget or unreasonable KPIs.


This feels like a multi-billion dollar industry in which every entity involved has the ability to sink the entire thing, and simply stated, nobody does because they all make money from it.


Marketing departments are burning money like mad. It's google and other brokers that make a ton of money.


There's twitter and facebook ads in the san francisco bart system and I just don't fucking understand who in SF isn't aware of twitter and facebook or what they're about.


There's a difference between performance and brand marketing. Bart advertising by Twitter/ Facebook is mostly brand marketing (not really tied to anything). A lot of marketing is about reminding you that a company exists.


Despite concentrated effort, I have yet to be able to forget that Facebook exists. Brand awareness marketing for companies as ubiquitous as that seems like lighting money on fire for the sake of it.


What about Coca-Cola? They spend billions on advertising even though everybody already knows who they are. They want to seem current. No brand wants to be thought of as yesterday's news. Facebook advertises to remind people that they exist and to seem like they're just as hip as Tiktok.


Brand advertising doesn't have to be "did you know that Company exists"; it can be "you should like Company more because Reason"


This is an important distinction that the article doesn't cover. The article focuses on a specific subset of advertising. Brand awareness ads are even harder to measure.


Are they just advertising the companies directly? There are cases where advertising even in a "saturated" area makes sense.

If FB feels like features like facebook marketplace or facebook dating are not reaching as big of an audience as they should, advertising to get the word out about those particular products the company offers is logical.


I mean most ad-tech firms can be considered successes by Silicon Valley's standards, and why would the marketing departments of corporations blow the whistle? They're making money too, probably twice a week, direct deposited.


You just described most of human endeavor.


> a Super Bowl ad cost three million dollars. Why? Because that’s how much it cost. What does it yield? Who knows.

This article is awesome. In my free time I'm building an advertising platform that topic matches ads off the content of the web pages. No tracking of users.

I'm hoping to allow people to host and run their own all inclusive self contained advertising platform for just a licensing fee. I also have a way to beat adblockers that I'm afraid of bringing to light since I only want it tied to my own companies completely non tracking and ethical ads.

Hope it's not a bubble! Though first I have to finish the work and get a few customers so it's not like I can't pivot if it is.


> I also have a way to beat adblockers that I'm afraid of bringing to light

Proxying ads through as first-party content?

If you really are invested in making them work ethically, consider these ground rules: https://bostik.iki.fi/aivoituksia/random/no-stalking.html


I find, as a consumer, I disagree with the text only requirement.

Videos are certainly off limits as a nuisance. However images convey a lot of information very quickly, and can be visually "skipped" in a way text cannot.

When presented an ad for protein powder alongside my workout diets article, I want to see what it looks like. The presentation of the product is an important factor in whether or not I pursue it.

It has to be remembered that advertising is a three way relationship, and all three stand to gain (presuming no scam). This is more complex than financials - displaying an advert leads to a bi-directional association in the consumers mind between the entity being advertised and the entity advertising it. It is beneficial to advertise products that have Brand values similar to yours (or ones you want to appropriate).

In all cases it can benefit the user to be advertised to as a means of discovery.

Many of us forget (or do not realise) that there are (and historically were a lot more) "papers" proudly proclaiming themselves "advertisers". People willingly read pages of adverts in order to discover products and services.

Anyway. Keep the image, it's worth 1000 words.


> images convey a lot of information very quickly, and can be visually "skipped" in a way text cannot.

Some images can be skipped. I installed an adblocker on this browser today because of an advertisement that could not. An obnoxious facial expression on both sides of the article can't be ignored; the subroutines running in a brain to detect faces and eye contact seem to be pretty highly prioritized. That's why those stupid youtube thumbnails are so effective.


>This is more complex than financials - displaying an advert leads to a bi-directional association in the consumers mind between the entity being advertised and the entity advertising it. It is beneficial to advertise products that have Brand values similar to yours (or ones you want to appropriate).

I agree, and I think that's part of why I disagree so hard with you on the primacy of images.

I mean, i'm not saying that a preference for text vs. a preference for pictures is objectively right or wrong, it's just a really good example of your aforementioned alignment of brand values between the content provider, the brand doing the selling, and the consumer. pictures are a way of associating your brand with values, but eschewing the (possibly extraneous) extra data in that picture, you are also associating your brand with a set of values.

I am also a consumer of protein powder... but you are way better off appealing to me with text. Ingredients, (tell me what the stuff is made of, and don't add any sweeteners) purity (Test for heavy metals or the like!) and then price are probably the attributes you want to bring forward, if you are trying to sell me a protein powder, approximately in that order. If you instead show a nice picture of the can or have a model preparing some in your ad, I'm going to see that, at best, as an irrelevant distraction. (again, I'm not saying those are the objectively most important attributes of a protein powder, but if you want my protein powder budget, that's how you get it; At a cultural level, the more I feel you focus on the things I care about and the less you focus on things I see as irrelevancies, the more I feel you align with my values.)

I mean, I'm not saying that pictures are good or bad in general, just that advertising with pictures and advertising with text have very different cultural connotations, and that advertising with text only can be a striking alignment with a consumer's values.


i.e. you want to see the facets you'd be looking for when choosing a product to purchase.

For many products and people that will just be the visual appeal, and advertisers target their widest audience.

This is a case where tracking can actually be seen in a positive light - I too think I would be more likely to convert if I saw a datasheet as an ad, but that's definitely not majority. At the same time, obviously fashion ads will convert better as images, in almost everyone.


>For many products and people that will just be the visual appeal, and advertisers target their widest audience.

I... think this is usually unwise. If you attempt to appeal to everyone, you appeal to no one. I personally think one of my advantages when I ran prgmr.com was a consistent brand? At the very least, it was very recognizable. (I don't run it anymore, and I'm not claiming to have done a great job when I did. But I can point out several mistakes I made where I would have gotten... big at least by my standards if I had zigged rather than zagged. I think I did a memorable, if not a good job at branding, and "just get my name right" is... well, it's halfway there.)

Personally, I think that if you want to appeal to different markets, you should use a different brand with a different customer-facing layer, even if in the bowels, the product is produced on the same equipment.

>This is a case where tracking can actually be seen in a positive light

I'm not sure? I mean, I think that the connection between the advertiser/brand values is important, and you destroy some of that if you tailor your advertising to the consumer... if different people get different views of the same brand, well, it's really different brands.

(Also, the decision to track/not track is a brand value decision in and of itself- a rather big one, if you can credibly communicate that to your customers.)


Attempting to appeal to everyone by serving a different ad based on tracking is precisely what I meant, but I'm thinking more from a platform standpoint than as a brand. An ideal marketplace would prefer to sell a spot to brands who advertise in a way that appeals to the buyer.


And since we re considering new advertising ideas, how the ads are presented matters. We could perhaps be thoughtful about when and how to present ads instead of plastering our sites with more banners than content because that's what adsense says that works. E.g. why are there not ads at the end of the video? Why are there 5 minute ads (seriously?)? Just saying "this worked" is not enough - this might have worked for an ad but destroyed the field for all other ads.


> Keep the image, it's worth 1000 words.

Rephrase that one, please. An image lies more than a 1000 words.


Even doing that you can block ads trivially. I can set up a filter right now to block any element on the hn page forever if I wanted. You can always serve an ad to most people, but anyone willing to slip down the rabbit hole and end up with u block origin will be able to foil any advert with a right click.


> I also have a way to beat adblockers that I'm afraid of bringing to light since I only want it tied to my own companies completely non tracking and ethical ads.

Beating ad blockers is not hard. Just serve them from the first party domain. If you’re not tracking users outside of whatever the first party tracks, you don’t need third party cookies either.

As a former ad tech guy though... I think the biggest hurdle you will run into is precisely the lack of tracking. It’s both problematic for privacy but also crucial for measuring ROI.


> Beating ad blockers is not hard. Just serve them from the first party domain.

But I've been seeing an increasing amount of talk and effort in the online marketing community about finding ways to bring this first party data into the existing third party data collection machines.

If websites start doing this, all it will do is bring the privacy heat down harder, directly on the publishers themselves. I hope that websites manage to operate without sharing that data with the martech world, but I fear that they won't.


> If websites start doing this, all it will do is bring the privacy heat down harder, directly on the publishers themselves. I hope that websites manage to operate without sharing that data with the martech world, but I fear that they won't.

I think this is the crux of the issue. Up until now publishers have been insulated from the problem specifically because third party cookies allow it to be not the publisher's problem. If publishers bring this in-house, then the martech market will push for a standard API to allow advertisers to evaluate metrics on the ads they place, which means we've just kicked the can down the road.

Fortunately this is not a distinction that GDPR cares about.


> It’s both problematic for privacy but also crucial for measuring ROI. Worse than that: buyers would have to not only trust the ad-network to not make up impression numbers, but also every single content provider.

But that would easily be solved by edge server ad splicing. Much easier to trust the CDN than a scrappy content provider. I really don't get why that hasn't been a thing for at least a decade. CDN business just going well enough as is?


But the article is wildly exaggerating the "nobody knows" gap of superbowl ads. There's an entire industry specializing in measuring the effect of "write only" ad channels and all the big TV advertisers spend a considerable fraction of their ad budget on commissioning those measurements.

Now the immediate, built-in metrics of online advertising have been eroding the business of that industry for quite a while. Those metrics are far more detailed, they boast low SNR and absolute precision as opposed to the murkyness of extrapolated trendlines in polls. It's very tempting to rely only on the built-in metrics then, and that's exactly where the problems the article is exploring are kicking in. Those old-school pollster methods that start with zero data and only measure the continual development of brand awareness plus the occasional campaign trace have something big going for them, which is that the little data they yield is universally relevant, whereas that ocean of numbers that is produced by built-in metrics can easily be a useless distraction or at worst actively misleading. Perhaps our would be wise for big ad spenders to employ some of that "zero data" brand awareness observation that could measure TV ads even when all the ad-spending is going online, into the realm of built-in metrics.


> an advertising platform that topic matches ads off the content of the web pages

Reading this article I had the exact same thought that I relayed to a buddy of mine. I've built some conceptual search engines on top of LSA.. and my thoughts from the article about brand/keyword targeted advertising is that it doesn't get to the heart of it.

To increase the advertising effects, not just the selection effects, you need to go deeper. Drawing on the analogy from the article a smarter teenager handing out coupons wouldn't stand just anywhere or stand just in line at the store. He would say, okay this is a pizzeria. (Assuming they serve nothing else) The smart marketer should think "Maybe I should advertise at italian restaurants." The analogy doesn't really show the full depth, right? There are many products where you can get some really off the wall potential customers you wouldn't know how to reach based on concept search.

Factoring in "documents" that they're reading online back into the search engine for conceptually similar ads is a good idea.


This largely already exists, but without the ethical non tracking thing.. which advertisers don’t care about.

Grapeshot Peer39 Etc


The weird thing about websites like YouTube is they do a combination of topic matching and user matching. Why bother with tracking users so extensively if you're going to just go ahead and demonitize videos that are "sensitive" content. Just place the ads in front of the audience regardless of what they're watching. At the end of the day, advertisers and viewers can't possibly care what video it's showing on as long as they're getting the right target audience. The only people that do care are journalists looking to write a sensational hit piece to fan outrage culture.

I hope your method succeeds because it would be a whole lot better than this crappy middle ground that we have right now.


> At the end of the day, advertisers and viewers can't possibly care what video it's showing on as long as they're getting the right target audience.

This isn't true?

Advertisers certainly do care. They don't want their ad dollars to be spent paying publishers for content that's controversial because it makes them look bad. It also has the potential to damage their brand.

This actually happened and is what led YouTube to lose a significant amount of ad revenue which in turn created the situation we have now.

I work for Google, opinions are my own.


> ... advertisers ... can't possibly care what video it's showing ...

I read this as 'advertisers don't care about the particular topic of the ad in general.' They don't care if you're watching a DIY home fixit video, or a coder streaming his working session, as long as you're a target for diapers and they're advertising diapers.


Ah, the old endemic versus non-endemic debate. Increasingly, you're right, but some brands really like the prestige of having their ads appear with content related to their topic.


And it sounds like the person you’re responding to is countering this very premise.

“They don't want their ad dollars to be spent paying publishers for content that's controversial because it makes them look bad.”


They care insofar as political controversy is concerned. Topically, they are not concerned. This is the distinction I feel does exist.


What actual difference does drawing this distinction make? It doesn’t change the advertisers behavior.


Yes, there's a whole subset of the industry dedicated to preventing such a thing, with players like IAS, DoubleVerify, MOAT, ...


>Why bother with tracking users so extensively

Because there is a good chance governments will pay for that data in the future.


> topic matches ads

Or, how about letting the publisher specify keywords they want to attract? I 'd love to have some control on which ads show on my site and do my own tests. If you have setup the tracking right, the advertisers have nothing to lose


I planned on writing both features, you could either select a few topics your site pertains to or I could parse the page and pick topics for you.


I think it is a bubble. But we are pretty far away from popping imho...


>advertising platform that topic matches ads off the content of the web pages

Is your unique prop breaking ad blockers? Because category/contextual advertising is not new.


Breaking ad blockers, respecting privacy, and the option to essentially white label the service. I see these things coming together to create a unique and value proposition.


How do you define "respecting privacy"?


Not gathering any data on the people that view or click these ads. The only data gathered will be "someone clicked this."


> I also have a way to beat adblockers

You'll never beat uBlock origin.

This is called "Contextualization". There are many DMPs for this kind of data. My favorite is Zvelo


Looking forward to your Show HN!


A very easy way to break this argument is to not look at huge known companies like eBay and Amazon, but brand new companies 1-2 years old that have grown almost entirely by online ads. Eventually word of mouth kicks in, but there are plenty of smart operators that built their entire brand and revenue off of ads.

Works best in online direct to consumer brands.


Reliably someone comes along every few months to question digital ads. I always come back to analyses of incrementality as the real proof.

Take an audience of X people. Divide them in two. Show ads to your test group, don't show to control. Watch your business grow and gauge the lift between the two audiences.

The companies that know how to advertise at scale do this constantly and can gauge the real effect of their ad dollars. Facebook, Google and others make these tests possible in their platforms, while other software suites such as Impact Altitude and VisualIQ allow you to do this kind of analysis and testing as well.

In the end, most of it proves out to be incremental. There are notable exceptions of course, but when are there not?


> Show ads to your test group, don't show to control

Which is the wrong experiment to run. The old adage is that 50% of advertising works, you just don't know which part. You need an experiment to prove that ad spending scales with ROI, as ad agencies claim. That may well be completely false.


That’s the thing - you run these test with individual campaigns in many channels. Digital gives you the ability to test this at scale as you grow your advertising, thus you can gauge with high confidence exactly what advertising is scaling with positive ROI.

Incrementality testing isn’t limited to your advertising as a whole - you can get down to very fine detail as long as your experiment is correctly designed and you wait for stat-sig results.


The basic experiment can be varied to allow for that.

Specify a set of zones. Target different levels of advertising at these. Look at sales trends. Rinse, wash, repeat.

Note that major corporations often designate specific areas for product testing. The Chicago area, and Australia, see trial runs of McDonalds products and store concepts, as an example.

The fundamental concept of testing advertising effectiveness is not new. Here's an account from 1909 (from one of my faviourite sources on advertising and media, Hamilton Holt's Commercialism and Journalism):

https://archive.org/details/commercialismjou00holtuoft/page/...


> You need an experiment to prove that ad spending scales with ROI, as ad agencies claim

There is a limited audience that can be influenced. Just like house ads on a site (where you advertise to sell your own goods on your own site), there's only so much that is affected because you have finite traffic. There is a curve for every permutation of context (demographic, geographic, etc).


> Take an audience of X people. Divide them in two. Show ads to your test group, don't show to control. Watch your business grow and gauge the lift between the two audiences.

So advertising industries use people as guinea pigs to study the "real effect of their ad dollars". No ethics committee, no informed consent, nothing.

Yet another reason to block all ads.


If you can ethically do something (show ads) or not do something (not show ads) it's equally ethical to run an experiment where you do the thing some of the time and measure the effect.

Internet companies run A/B tests all the time, and it's not controversial.


Hyperbolic.


Isn't that literally the test described by FB economists in the article that showed that selection effect was 10x the impact of advertising?


Agree. I have used the term "incrementality" to communicate the incremental benefit of a given ad compared to a control whereas the article uses "advertising effect". Measurement is also difficult because every ad platform grades their own homework (they each have analytics that attributes sales to their platforms liberally).

It is important for a brand to have their own attribution platform that measures incrementality as well as the relative contribution each ad exposure makes toward a given sale.

Both of these things are possible to measure. The problem is that the band of users that display positive ROI (when incrementality is measured) is so small that people don't believe the data.

Additionally, brand exposure is hard to measure and almost completely ignored in digital advertising. Over time I imagine that there will be more research in this area (beyond just measuring an in-view ad impression)


How do you separate "people who haven't seen an ad" into a group in Google analytics? I don't believe "organic" source does that, because that means they weren't targeted by the ad in the first place, creating a bias.


Advertisers have many tools to measure "ghost ads" aka "people who haven't seen an ad but would otherwise have qualified for all your target criteria". See https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2620078 as an example.


That's of course possible to measure in theory. I meant it as a response to "Facebook, Google and others make these tests possible in their platforms" since I haven't seen it exposed as an explicit option on either.


Then you haven't been talking to the right ad sales teams. Google and Facebook have entire product options built around this specific concept. You can run a "ghost ads" test on Google for as little as $20k in ad spend; it's relatively accessible even for smaller players.


For Facebook, Reach ads have a brand lift objective that will estimate for you. If you spend large amounts they have a measurement team that will run the actual study for you. Source: I'm running one right now for a CPG brand.


You can run this yourself without any help from them: show one group ads for your site, and show another group white rectangles. Compare performance.


Facebook has this exactly this tool, aka Conversion / Brand Lift [1]. It's a real experimentation system, not a "simulated" one like Google's Ghost Ad.

[1] https://www.facebook.com/business/help/688346554927374


Yep. Lift tests are solid gold. A lot of people pan FB ads but the reality is they can be very incremental.

The flip side is that not every campaign, targeting strategy or ad will be incremental. You have to test and retest your way to it. A blanket assumption won’t work.


Off the top of my head, you could do geographic bucketing. Take say 100 cities, and only run ads in 50 of them.


Geo tests are useful for sure, but also require a lot of data to get statistically significant results. Any noise in your data (seasonality, PR, etc) has to be taken into account as well. They’re harder to execute in general but can work well.


The interest is more on markets than individuals, in general, so what you're measuring is market response given advertising exposure, or more critically, ROI given spend.

The fact that Web and AdTech allow the appearance of individual-level targeting does not necessarily make that a Good Thing.


I'm running a campaign that spends about $10,000 a day for a brand on Facebook. In fact at that level they will run said brand lift study for you. So yes, despite this articles implication the data does exist and we do know the difference between advertising to an audience and not.


That's millions per year. What general class of industry are you in?


The average "target" client on the lead list of your average big name advertising agency in a European country with a population of 50 million will have a yearly spend of 50-100 million across all channels, with 1-10 million going on agency fees excluding 3rd party costs. 10k per day on Facebook is a small consumer start-up levels of adspend.


1. In the grand scheme of advertising it's actually still a fairly small budget. 2. For this advertiser they really only advertise q4 so it isn't quite that much. 3. It's a CPG in a grocery store is all I can really say.


Acquiring an audiences to divide into a split test is the hard part.

It is something that could work for retargeting existing users but doesn't work for acquiring new visitors.


What makes you believe this to be true?

You define an audience. You split it. You test and measure the result.

What component of that strategy doesn't work for new visitors? Many eyeball vendors (Google, Facebook, heck traditional TV and other media!) are set up precisely to allow for such cases.


Not quite.

One tool with FB lift tests is to make a lookalike audience. FB will then split that audience in two for you so you have a test and control group.

The original test required two ad accounts and keeping your overall advertising static (not changing anything) for the duration. Today it is much easier and has a lot more features.

Google does a search lift test with YouTube as well. You can run a large set of ads against an audience in YT and google will either suppress them for a subset. Then you can see your overall organic lift based on your video ads.


FB can track ads using clicks and view through. With a control group, you can only use view through. I am just skeptical of how it is a fair test especially when FB has an interest to prove that ads work.

YouTube brand lift is an indirect measure that is hard to translate to actual sales to see if the ads were cost effective.

The math is fuzzy when measuring marketing ads and it is real hard to be truly scientific.


The proper test is to use viewthrough for both the experiment and control


The concept, principles, and methods, are taught in the context of marketing and advertising academic programmes.

See, e.g., ADVT5440 and ADVT5501 at Webster University, for example:

This course emphasizes the importance of critical thinking in the planning and development of message strategy for advertising and other marketing communications tools. Class discussions explore the decision making process and development of criteria for evaluation of alternative message strategies.

Or in related textbooks, e.g.,

https://www.worldcat.org/title/marketing/oclc/61458339


This is a very interesting point, which in fact plays in defense of original article.

Bob Hoffmann, very influential figure in advertising (http://adcontrarian.blogspot.com/) likes to point out that there were not that many companies which built their strong brand with online advertising only.

OK, he is old and grumpy dude and he dislikes online ads, but this is a fair point. Once company becomes big enough, it strives to buy a Super Bowl ad spot. And we are well into 10 years of internet being mainstream media, but how many brands were built online only? Not that much, and I'm saying it as "online ads work", kind of guy.


I can name a handful that I've never seen an ad for on TV or in print (or maybe 3 or 4 years after using them). Twitter, DoorDash, Lyft...compared to SkipTheDishes in Canada, which has commercials on during SNL but maybe it's already hit peak internet marketing there, or maybe more appropriately GoDaddy which wasn't much until their Superbowl ad.


Google Twitter, DoorDash, and Lyft + billboard. Just one example, they all do plenty of non-online advertising.


Another thing marketers in US and to a certain extent Europe fail to see is how digital has evolved in Asia and think through what it means for their own work. The same marketing giants which spend 90% of the hundreds of millions of dollars per brand per year on TV in the US spend 90% in digital in China and are increasingly shifting in other Asia markets. This reflects shifting consumer time spent on vehicle.

Now big company marketers are used to thinking of US as a homogeneous market for efficiency reasons and so TV still works in US if your target audience claims a broad demographic. However, they're beginning to learn that you'll simply not reach enough consumers if your target demographic is say young adults in the West coast if you do a TV heavy plan. US in general lags China in media landscape shift but the media behavior of the more valuable demographics are actually much closer to China than averages tell you.


the article isnt making the point that there is no value in advertising, but that it's highly overstated. One really needs ads - the 're a very effective way to reach users. But after that initial push, does spending more really return more?


One thing I've always thought about ads is the subconscious impact that they have of building brand recognition and awareness. Especially for something which would typically be purchased infrequently or irregularly.

I might be at a grocery store and I need to purchase something like dishwashing liquid. If I'm staring at two brands on the shelf priced identically (or near enough) I'm more likely to purchase the brand I recognize over a brand I've never heard of. How do I recognize the brand - from advertising.

That is not something you can measure with tracking metrics embedded into a banner ad. I'm sure there must be studies on impact this has.

The other thing I suspect online advertising works very well for is service based businesses, the kinds of things you used to look up in a phonebook. The last time I needed to find a plumber I typed my suburb name + plumber into search engine I imagine a lot of people do similar.


This is exactly why TV advertising is still important to those brands!


...there are plenty of smart operators that built their entire brand and revenue off of ads.

Can you name one?

I find it very hard to believe there are any companies that have scaled up only using online adverts. Why would the founders of a business do that when they can grow in their local market by talking to people as well as buying online ads for wider reach?


MVMT Watches, Boll & Branch, Casper, so many DTCs. Yes at some point word of mouth kicks in!


Wayfair - you can listen to the NPR podcast "How I built this" where they talk about building their entire business around domain names and pay-per-click advertising (7 billion market cap).


Here's one I worked on when I was at CogoLabs: https://venturefizz.com/deals/autotegrity-acquired-adp


This wouldn't be too uncommon in branded ecommerce. If you are selling well known brands it is going to be very hard to get decent organic search rankings for them in the short term.


Yeah the golden egg may be in long term influence of advertising, which is super hard to measure.


This is a rather unimpressive article. Yes, brand advertising is a disaster, just like it has always been. But to say that all digital advertising has unknown ROI is ridiculous. Digital direct response advertising allows very accurate ROI calculations. (Admittedly, a lot of advertisers are not applying the tools to their advantage. They call that the "Google stupid tax". Ditto these days on Facebook.) And direct response advertising is nothing new. Mail order guys were cleaning up by running early (expensive!) experiments that showed if they were going to go out of business. Oddly enough, when you have skin in the game, you follow the money much more closely. Who knew? The fact that golf course brand advertising deals don't pay off is not news. They never have much.

The bad news for digital direct response advertising is that the platforms are starting to remove the knobs that actually let people determine and optimize their ROI. Google is in the process of actively removing ad functionality and data that has, historically, been crucial to ad profitability. Google claims their machine learning can see much more of the data available, so "trust us." Perry Marshall, Google ads guru, has recently held several webinars about "Why Google is Objectively Evil."[0] Not pretty.

Hi this is the author of the article. You're just making the exact mistake this article is about: you assume people who click on your ad and then buy something, bought something BECAUSE of your ad.

From the article: "Suppose Luigi’s Pizzeria hires three teenagers to hand out coupons to passersby. After a few weeks of flyering, one of the three turns out to be a marketing genius. Customers keep showing up with coupons distributed by this particular kid. The other two can’t make any sense of it: how does he do it? When they ask him, he explains: "I stand in the waiting area of the pizzeria."

It’s plain to see that junior’s no marketing whiz. Pizzerias do not attract more customers by giving coupons to people already planning to order a quattro stagioni five minutes from now."

It's the same in online marketing, you often target people who are searching for say a pair of shoes. People who are searching for shoes have way higher baseline probabilities of ending up buying a pair of Nikes, whether you show them a Nike ad or not. So if you do not correct for this 'selection bias', you have no idea what your ad did.

The research I describe in the article clearly shows (and please look it up yourself, the links are all there) that selection bias is HUGE, and that it's hard to know ROI, because true advertising effects are tiny if you measure them in an experiment.


If you're using your digital marketing tools correctly you're already correcting for this. Instead of measuring how many people click on ads, measure how many people click on ads and then compare it to how many people click on organic results to the same query. Or run ablation experiments where you stop running the ads and see what that does to your clicks & conversions. If you were making $X + $Y with the ads and then you stop running them, hold everything constant (no new campaigns, no product changes, no seasonality), and you're suddenly making $X with organic traffic remaining constant, it's very likely that you're making $Y from your ads, particularly if $Y was directly attributable to ads-related sessions. If instead your organic traffic is now making $X + $Z, it's likely that your ads cannibalized $Z in organic spending and they are actually making $Y - $Z.

Not saying all advertisers do this, but it's pretty basic data science. You should always have a control for every experiment you run.


Sure, so where the data showing that most people do this?

When I was younger, I would read over and over "don't do X" when reading about how to repair a car or write a program. And I would think, if this advice is everywhere, how could anyone miss it?

And then, over time, I learned that there is a whole culture of doing things wrong, in many areas.


How do you expect to get that data? It's buried in their Mediamath and Optimizely accounts.


Hi Jesse,

I saw a lot of youtube channels and reddit posts discussing how to optimize their ad spend (for example, https://www.youtube.com/watch?v=1O6feWOsbLs)

In the video the person starts a new online store and shows how he measures his return on advertising investment. It seems to be a pretty direct correlation between his ad spend and his increased sales.

How do you match up your thoughts on advertising with the prevalence of these kind of "advertising success stories"?


I don't think the article says advertising never works, but that people should be careful when measuring. Lets stick to the mentioned eBay example. I can totally imagine advertising for the keyword "ebay" not being worth a lot. Those people are likely to visit that site anyway. I was more surprised when "shoes" & co were mentioned. I would have expected bigger impact for those.

Hardly any of that applies to a small store with no brand awareness, since there is little/no of the "would have clicked anyway" mentioned in the article.

Another problem with measuring can be the competition. Building/Changes brand awareness (incl relative to competitors) takes time and seems unlikely to possibly be fully measured in a short experiment. Especially if the competitor currently doesn't run ads... but you not betting for them anymore might change the price and thus calculation for them.


The effects may be low but what is the alternative? You suggest there's a digital advertising bubble but to have a bubble with the assumption it will burst, you need to show that advertisers can achieve a better return by doing something else.

There's no digital marketing bubble more than there is a traditional advertising bubble. There IS however a conflict of interest in advertising that's caused by the agency which performs the advertising being tasked with showing a return on investment.


I agree that advertising as a whole might be a bubble. In fact, my next piece is about TV advertising which is arguably worse. See: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3273476

I do think it's more accepted in traditional advertising that we just don't know how well it works. In digital advertising there is a grand illusion of measurement.


Hey Jesse,

I spent 6 years working in ad-tech, and I was researching the incrementality effect of ads, selection bias and stuff like that for last 3 years. I want to let you know that your article is good. Online advertising is not a bubble, but your article perfectly explains why it is much harder than it seems.


The thing about bubbles is that nobody knows they exist. So an insider such as yourself saying, “there is no bubble,” is actually strong evidence of said bubble. Necessary but not sufficient.


This isn't really the case. Bubbles usually have plenty of people claiming they are bubbles, and people on the inside privately acknowledging it.

In online advertising there are few people on the inside who think that non-brand advertising is a bubble. It just works too well, in too many places, and too many people are making money using it. It's reliable and effective, and those just aren't attributes associated with bubbles.

Yeah, attributing everything to the last-click isn't the best measurement in the world. But as pointed out elsewhere there are techniques to avoid it.

And there are enough direct-to-consumer brands which launch on Instagram and do nothing else to be able to see how effective it is.


No, it's perfectly reasonable that everyone knows there is a bubble, but nobody knows when it will pop.

"Irrational exuberance" is a famous quote about the 90s stock market/internet bubble, and it was in 1996, when the party was just getting started.


Thanks a lot! :-)


Not sure this has much significance, but as a consumer I usually skip online ads or tune them out mentally as they are so pervasive it’s a nuisance. T.V ads work on me to an extent if I were watching live T.V. but I try again to avoid them like the plague.

Some news sites make ads agreeable if it meshes well with the content (like NY Times and such).

The bottom line I think is that there’s too much competition for my attention and it gets exhausting unless the ads are really well thought out (original ideas) or subtle—in which case the probability of me seeing the ad is less, but the effectiveness most likely increases as its less like an ad and more like relevant content


I disagree.

Most of the people I grew up with today know that it’s Miller time, that sometimes you feel like a nut, sometimes you don’t, or that coke is the real thing. They learned that from TV.

Online ads? They don’t trigger anything for me. They either need to deliver information contextually, deliver preferred placement for something I’m already looking for, or be deceptive.


> I grew up with today know that it’s Miller time, that sometimes you feel like a nut, sometimes you don’t, or that coke is the real thing.

True. I acknowledge here that anecdote is not a synonym for data, but I will offer that despite those phrases having been seared into my brain for most of my life, I don't actually drink Miller, eat Almond Joy or Mounds, or drink Coke.


If you were the kind of person who drank light beer, candy, and soda, I bet that jingle would spark something.

Ad quality these days has gone down for sure. Everything is formulaic and established and safe, yet nearly every major ad over the course of advertisement history was major because it was the opposite of these. I guess quantity has gone up to compensate.


I'm not big on beer or soda, but I do have a candy habit!


Online ad metrics tell people “what” happened, but people expect it to tell them “why.”


> but to have a bubble with the assumption it will burst, you need to show that advertisers can achieve a better return by doing something else.

To burst a bubble, you don't have to show them something that works better, you just have to convince them to stop drastically overpaying for what they've been buying.


the bubble is in the price premium of online ads


Hi Jesse,

I do growth and run experiments for a living for DTC brands. I liked this article but the research on ebay brand advertising is missing the point about competitors. If you have competitors bidding on your brand, I've seen multiple times really strong degradation on performance.


This only applies if the advertiser could be better expected to get most of the business from those searches.

If someone searches "nike shoes" they might well get them on someone else's site. Whereas someone in the pizzeria is already buying at the pizzeria.

I agree it's important to measure, but I think your concern is overblown for most companies and most non-branded searches. Assuming those companies are measuring.


This is an empirical question. I suggest you read the research I cite. For Facebook: https://www.kellogg.northwestern.edu/faculty/gordon_b/files/... For display ads: https://www.aeaweb.org/conference/2014/retrieve.php?pdfid=98... For search: https://pubsonline.informs.org/doi/10.1287/mksc.2017.1065

The problem is: yes, there's only a tiny chance somebody who searches 'nike shoes' ends up in your store. But the probability that someone ends up in your store BECAUSE he saw your ad is even smaller. So if you don't correct for selection effects your going to overstate ad effects by orders of magnitude.


Just did. One study is about brand keywords, which massively heighten the risk for what you're talking about. (I specifically excluded them in my earlier comment)

Another study is about display ads, paid for per impression. The study gives an average figure of 0.02. These are also not the typical successful google or facebook ad campaign, and are more akin to old tv ads.

The 66 page FB study isn't clear, but it also seems to be talking about ads paid for per impression? This is not what people talk about when they say you can easily track online ad returns.

Ppc ads are easy to track. You send a user to a special landing page, and you know exactly when someone got there via an ad, as only people who clicked ads go to those pages.

That said, a lot of advertisers don't do this, so they'll definitely have very real measurement problems.


That's what conversion lift studies are for. Deliberately don't show ads to a holdout group of eligible users, and measure the difference.

e.g., https://www.facebook.com/business/help/688346554927374


>It's the same in online marketing, you often target people who are searching for say a pair of shoes.

This is funny, because on HN you often see complaints about online advertising being horrifically bad because "it suggests me the products I have zero interest in", hence "online advertising sucks".

But that's the whole point! These people are complaining that they are not getting pizza coupons when they are entering pizzeria!

If it will suggest you something you are interested in already, chances are, you will buy it anyway. And if you will be suggested something strange and you will buy it, it will be incremental customer and incremental sale, and you might even become a regular client.


> If it will suggest you something you are interested in already, chances are, you will buy it anyway

For me, the key bits of advertising are a) knowing the product is available b) knowing that its specifications meet my needs and c) knowing the price. Without knowing those things, I'm unlikely to buy the product. If I know (a) and (b) and want the product but haven't bought it, then I'm probably waiting on (c).

Perhaps this is an argument for the "coupons in the pizza lobby" (or at least "coupons in the food court") type of advertising. I actually like the sorts of printed catalogs/advertising circulars that stores like Target or Best Buy provide at the store entrance, because although I may have gone there to get one thing I may end up picking up another if conditions (a,b,c) are favorable.

Magazine advertising seems to work this way; if I pick up a copy of Mac|Life magazine then I'm probably already interested in Apple products as well as compatible hardware, software and accessories. Unfortunately Mac|Life is pretty anemic at the moment (along with most of the remaining computing enthusiast print magazines) so this model seems to be in trouble for print magazines at least.

With Mac|Life the decline of third-party Apple dealers probably hasn't helped, and probably the likes of Amazon and Wal-Mart don't feel they need to advertise there. But I'd like to see more ads for software, because the Mac and iOS app stores are still pretty terrible for discovery.


Well its pretty easy to tell if its because of the advertising. Just turn it off for a while and see if it affects revenue.


That's not what the article is about - but try scaling it back to 50% and see if it results in 50% drop. The graphs show that the relationship is probably very nonlinear


Really not that easy, except if you can everything the same, aka go back in time.

Otherwise, causal inference is sadly not easy.


thats why seller should modulate buying ads with a random stream of bits, such that the impulse response (of linearized approximation in tangent space for sales / advertising dollar) can be estimated.

of course if the advertisement platform is simultaneously a dominant search engine, they can simply choose to directly modulate your discoverability through the search engine, in which case it is closer to extortion as others point out.

as a potential buyer, I'd much rather have (economical) censorship free decentralized platform where every manufacturer / seller can advertise products / parts with relevant specifications / metrics. Think DigiKey, but without a central arbiter. Obviously a lot of products that are actually superior are superior because they have a better understanding of what people need than what conventional metrics show (say not just the cheapest capacitor, but perhaps the cheapest capacitance divided by electric series resistance or whatever, for a certain niche use). This would result in placing the burden of comparing products among the manufacturers, who will also make up original but useless metric formulas with the sole purpouse of making their product rank highest. So instead of having to browse products, people are browsing metrics, and it's up to both manufacturers and end users to communicate the utility of each end metric.

Something I don't like about the parts selectors like DigiKey et al, is that I can filter and rank according to proposed properties / columns, but I can't enter a formula in terms of properties, to show me the highest ranking. I always end up having to download and scrape the full list of parts so I can perform this ranking in a spreadsheet... If their search fields allowed formulas, and if people were logged in, the manufacturers / resellers could contact you to find out what made you formulate this specific metric or loss function, which gives feedback to the manufacturers what buyers are interested in. It would also give the sellers opportunity to correct the buyer that in his or her design the buyers' metric is faulty, and point out why...


> seller should modulate buying ads with a random stream of bits, such that the impulse response (of linearized approximation in tangent space for sales / advertising dollar) can be estimated

Could you unpack this a bit? (I'm not making a point or anything, just confused and curious and not sure that googling would help me understand.)


> It's the same in online marketing, you often target people who are searching for say a pair of shoes.

FYI - you're not clearly delineating between capturing intent, prospecting, and branding. Worse, your using intent capture as a catch-all for all advertising. That's not how it works.

> Pizzerias do not attract more customers by giving coupons to people already planning to order a quattro stagioni five minutes from now."

The alternative is that the Pizzeria does zero promotion and those who are interested in "ordering a quattro stagioni five minutes from now" end up going to somewhere that does.

Ads, on Google specifically, is a zero sum game with an auction based fee structure which mostly is about capturing potential customers' intent to buy. This is the true "evil" of Google, as you basically are forced to pay a tax on all online intentions to purchase via a search from Google (it's also why Google is so scared of Amazon...hence, Google Shopping)

> and that it's hard to know ROI, because true advertising effects are tiny if you measure them in an experimen

It's impossible to know equivocally why a person makes a purchase, digital, traditional, or otherwise. Theres a lot of research on this topic but until its conclusive, we'll never have a "true" ROI.


You make it sound as if advertisers do not A/B test. My experience says they do. But YMMV I guess.

It's obviously hard to convince an advertiser that her work is meaningless.


I'm still reading the article but thought I'd mention some popup infocards (such as Audis and turtles) are cut off near the end since it's too long. At least on my desktop Chrome browser. I can read them via browser inspection but that won't suit a wider audience.


Does this apply to mobile app install ads? I just don't see how those products are accessible to consumers in the same way without the awareness driven by highly targeted, experimental ad campaigns. I'm thinking King.com or Supercell type companies.


What if advertisers jack up the cost of advertising to the point that competitors can't get a foot hold. Don't think of advertising in terms of ROI. Think of advertising as a form of extortion.


It's not the same. It's handing out coupons to people who are hungry and are looking for food; not people in the waiting area.


Google removes targeting knobs because despite what marketers think, humans consistently underperform algorithms when it comes to targeting. Typically, the people tweaking the knobs have reverse incentives because they don't want their jobs to be automated so they love these knobs. But they are just constraints on the bidding systems that end up delivering poorer performance of the campaigns.

YMMV but for the vast majority of campaigns, the algorithm does know better.

Disclaimer: I've built bidding systems for multiple ad companies, so I'm surely biased towards "the algorithm knows better".


I think it's not about whether algorithms are better than humans. It's about whose profits these algorithms optimize. Google's algorithms tend to optimize Google's profits.

Advertisers utilize algorithms too. But it gets more difficult when Google removes/limits access to information and knobs.


I agree. Third party ad companies bidding on behalf of advertisers for the best inventory have incentives more aligned with advertisers IMO (as opposed to Google and FB who tend to side with publishers since they control inventory). The main caveat is that it comes at a privacy cost (broadcasting cookie information on ad exchanges).


> Digital direct response advertising allows very accurate ROI calculations

How many ads are direct response? How many are simply clicked because they are just above the same website's entry in search results (i.e. users were already heading to that site, the ad was just there as google tax)? How many legitimate clicks on an ad that did not led to sale are discarded by google as "invalid clicks" (my adsense report has 20% invalid clicks) ? It's kind of shocking that the internet's most lucrative market does not answer those


>(i.e. users were already heading to that site, the ad was just there as google tax)?

I saw research which indicates that it is a good idea to pay the google tax. Users heading to your site may get distracted by your competitors or other stuff. The more ads are shown the less organic results (which are not easy to control) are visible without scrolling. In best case, the search results are showing your ad immadiately followed by your organic result, making up the whole screen real estate. Wherever the user clicks, he ends up on your site. Also, cost per click tends to be lower for brand search terms.


By my reading, direct marketing was LITERALLY the example used in the article that showed some of the dodgy reasoning/metrics behind common measurements of marketing success :/


What I notice is that internet advertisment is pretty selective, I dont know about effective... If your interests happen to diverge from mainstream just that bit enough, you can end up in a pretty much ad-free zone. I happen to watch a lot of conference recordings on YouTube, and most conferences dont monetize their channel (yet). But thats not the end of the story. Stay away from mainstream, and you get complete ad-free shows. Take Joe Rogan for instance. The people he hosts are largely pretty interesting, but the way he does controversial topics pretty much led YouTube to demonetize him. Which, for the consumer, is a blessing. Because you get 3h talkshows without a single bit of advertisment. Or ARTE, which is a german/french coop television provider. They have very interesting content, but a policy of not enoying with ads. Which makes their YouTube channel even more worthwhile subscribing to. I could go on, the pattern seems to be the same. To be honest, the more cheesy a program is, the more likely it is that you will be flooded with ads.


> stay away from mainstream Joe Rogan's podcast has millions of subscribers and multiple ads per episode (not counting ads on various cuts/highlights from the episode) — are there more mainstream podcasts on youtube?


Interesting, I dont see this. I used to watch JRE on youtube with my iPhone, and now consume the same channel via an Apple TV 3. I never got a single ad. I know that he is doing his own ads at the beginning of the show, but only in the podcast version. The YT JRE shows are completely ad-free for me.


I think a lot of people still see ads on demonetized videos, the creator just doesn't see a penny of it.


So, how is Rogan funded? And what is he advertising? His Patreon? Product placement? Ideological placement?


There are over 5 minutes of ads at the start of every Joe Rogan podcast, as well as others throughout. One analyst suggests Rogan has acheived a net worth over $1bn based on the number of downloads & estimated advertising revenue based on those figures: http://www.insideradio.com/podcastnewsdaily/joe-rogan-podcas...


As written above, I know about the intro ads, but they are only being done in the podcast version. The youtube versions of the same talkshows dont have a single bit of advertisment for me, neither at the beginning nor in the middle.


Only a portion of his shows gets demonetized, far from all


> I could go on, the pattern seems to be the same.

I think a lot of people would be interested on similar examples


I've always wondered about those adverts for the website I'm searching for. If I type its name into Google, I'm already 100% committed to going there. Sometimes I click the advert (it generally depends how much I like the company).

The other aspect of online ads that strikes me as ingenious but probably not sustainable is the way Google inflates the auction system with fake money. Anyone who's run a website will have received a letter offering hundreds of dollars of free advertising with Google. Of course, it's an auction so the presence of that money just drives up the cost for everyone. Google wins every time!


There was a post about this recently. They need to buy the ad to keep their competitor from being the first result. https://www.seroundtable.com/basecamp-google-ad-28161.html


Well, at least there is no law allowing ISPs to serve their site more slowly unless they pay a ransom (I mean business professional tier).


I had the same thought. Our PPC consultants strongly recommended that we do branded ads and I pushed back against it using this same logic. Ultimately we performed a test, but the results were very different from in the article—we did find that a significant percentage of those who clicked our branded ads would otherwise click the organic results... but far from 100%. And because cost per click on branded ads is so low compared to other ads, it appears that they are still profitable for us, even once we take into account the users who would have arrived through organic links if the ads didn't exist.

This was and is surprising to me. The only explanation I have is competitors bidding on our brand keywords and taking traffic that would have come to us absent any ads. Which makes the whole thing look like a nice racket for Google. Regardless, for now we pay since the alternative is apparently to lose those users.


If I had a brand, I'd be tempted to bid it up with ads directing to ad-blocking extensions. Does Google allow that?


It costs the ad creator money every click and rewards google for mixing ads into the search results in a confusing way. This is a sketchy practice when the ad is for the exact product or site you typed into the search bar - as another commentator mentioned, the dynamic forces you to buy the ad to keep competitors from stealing the spot. Toxic


It's more than competitors. When looking for a specific site like ebay, paypal or name of popular software, the first paid results are regularly untrustworthy, if not plain scam or distributing malware.

Either the legitimate site pays to be first, or it can watch customers go to hell, literally.


It's a defense strategy. And it's necessary.


"Nice organic customer flow you've got there. It'd be a shame if it all went away because you didn't pay us." --Google


"It's not our fault that our ads look entirely identical to our search results"


It's seemed pretty obvious for a good decade that, if a bubble were going to pop, it would probably be related to advertising. Because if online advertising falls off a cliff, that hits two of the big tech employers directly. And you can be sure there would be major secondary effects on all the companies whose plan is to more or less never make money but be acquired.


Overstated.

This article assumes that: - All online advertising is Google search - That brand search advertising is representative of the entire industry

There are plenty of companies making double-digit ROAS (return over ad spend), especially direct response advertisers.


Hi, I'm the author of the article, and I don't assume all online advertising is Google search. I also cite research on display advertising (meta-study of 432 display experiments on Google): https://www.ssrn.com/abstract=2701578 And on Facebook advertising: https://www.kellogg.northwestern.edu/faculty/gordon_b/files/...

The problem with all online advertising is that there are huge selection effects, which are hard to correct for using conventional statistical methods. So you need to do experiments. And when economists do experiment, they find that advertising effects are so small that they are hard to measure.


There is a selection bias in these studies as well -- that you are focusing on large, already established brands that have good brand recall and people who had intent to purchase there anyways.

For smaller companies that are just starting out, it's relatively impossible to have prior intent when people don't know who you are or what you offer. There are a number of companies who started with nothing and grew their business via online ads and this seems like a giant blind spot in the article as well as the studies that you mentioned.


> There are a number of companies who started with nothing and grew their business via online ads and this seems like a giant blind spot in the article as well as the studies that you mentioned.

But is that number statistically significant? some do, how many others tried the same route and failed, how many grew without it, etc


> using conventional statistical methods.

Experimental design, analysis of variance are such. E.g., for the farmers and from the corn fields and hog pens of Iowa:

George W. Snedecor and William G. Cochran, Statistical Methods, The Iowa State University Press, Ames, Iowa.

These methods have been widely used in the social sciences -- e.g., my wife, Ph.D. in mathematical sociology from Hopkins, got quite good with that material. The field is quite serious and mature and goes well beyond just A/B testing.

For the practical challenges of the article, academic fields closer than economics include statistics and optimization.

For the Lagrange multipliers in the article, those likely would be from the Kuhn-Tucker (Karush-Kuhn-Tucker) conditions. There without some special assumptions, e.g., having to do with cases of convexity, the conditions are only necessary for optimality and not sufficient. Generally in practice, it is more difficult to get sufficient conditions.

Yes, correlation does not necessarily mean causality. Usually showing causality needs a mechanism; in practice showing causality just from data and/or statistical methods is difficult and rare. But in practice, correlation can be powerful enough to take money to the bank.


Do you think that the situation is due to an arms race kind of scenario? -If everyone but one stopped advertising then the one still doing it would reap massive benefits? So advertising is a form of obstructing the competitor.


I can confirm this. I've run similar studies at my current employer (some of them with one of the persons you cite in your article) on multiple very large advertising platforms for display advertising. The causal ad effect is very often indistinguishable from statistical noise.


Maybe overstated, but if "all" the article shows is that Google search ads don't work, that's a big deal.


Worth mentioning the conflict of interest that you work for facebook's Ads Growth.


Ah, not anymore. Outdated information, I work on a different advertising platform :)


How do you know it's not selection effect and the ROAS number are BS just like they are with Google? Have you tested?

Google and Facebook are 60% of the market, so if it would be only them this is important.


The ROAS numbers given by FB (your employer) are far from being a real estimate of the causal effect of adverts. For example, there's no way to have global holdback against other advertising channels not controlled by FB. Double-digit anything are easy to get on any advertising perfomance metric if you don't scale your spend, so it's not really an argument.

(Disclaimer: I've built multiple bidders & ads incrementality models over the years so I'm probably biased against the "supply" side of ad inventory).


If a company has incrementality tested and is really making double digit ROAS they aren't spending enough haha.


Not sure if you’re joking or not, but it makes obvious economic sense to keep investing in something that has a higher rate of return than other investments - and you can’t reliably get a 50% return on any other investment I’m aware of.

And it only takes a moments thought to realise that once everyone starts doing this, the marginal rate of return is going to be driven down to the going rate in the rest of the market.

Like any other investment, if it sounds too good to be true it almost certainly is.


As the other commentator identified, you work @ FB -- could you please provide the following three scatter plots to support or disprove your claims?:

(1) Size of Company vs. ROA

(2) Advertising Expenditure by Company vs. ROA

(3) [Advert %] vs. ROA

I hypothesize you'll see a rapidly decreasing return on advertising due to size, and would love to be proven wrong.


Not at FB anymore but I would assume your hypothesis isn't too far from the truth. It's also true that there are hundreds of thousands of small businesses that thrive thanks to online advertising.


The US currently has about 25M small businesses. How many of them use digital advertising? What testing is done to ensure their ROA isn't a waste?


"New"? Pinboard-guy Maciej Cegłowski has been harping on this for years now: https://idlewords.com/2015/11/the_advertising_bubble.htm


Just as Google won the search engine wars by helping people find what they are looking for, the e-commerce winners will be the companies that help people find what they want to buy (reliably and with confidence).

Retail companies are blind to just what a shit-show their websites are (a lot of them even have ads in their online store). Any company that solves this problem for their sector will win it, and this is good news for techies as every company can and should have a unique solution.


Amazon more or less won didn't it?

It doesn't have total domination of ecommerce but frankly it'd run into anti-trust issues if it did. No company is going to do ecommerce bigger than amazon without getting broken up so yeah... amazon.


Moving more and more away from Amazon. If I especially like a product or company, I'll see if it costs about the same to buy direct and do that. I've found that lots of companies actually have better deals on their site or offer a coupon.


You're also far less likely to receive a fraudulent product buying direct from the company versus Amazon thanks to the third party sellers and commingling of inventory.


> I've found that lots of companies actually have better deals on their site or offer a coupon.

If coupons and discounts are the best the competition have to offer, then Amazon doesn’t have too much to worry about.


For me, avoiding the counterfeit gamble is a good reason to step outside of Amazon if there is any other reasonable option.


Yes.

(1) Yes, I know that Amazon sells some millions or some such different products, but my experience shopping (recently moved and have done a LOT of shopping) is that the company making the product can have a good enough Web site that shows much wider range of products, e.g., for wool blankets many more colors and patterns.

(2) To me the key to Amazon is their quite well done Web site that makes it easy (a) to find products and (b) to get relatively good information about them. But can do well on (a) with just keyword searching at Google, Bing. For (b) can do well at the Web site of company making (importing, whatever) the product.

Then, yes, Amazon also pleases customers with better, faster, cheaper shipping options, their Prime program, good returns policies, relatively close warehouses (Walmart stands to do really well on this as they get their Web site polished), customer reviews of products, Amazon Choice house brand, one account for all the wide Amazon product choices instead of (having to type in banking, shipping details for) accounts at each of a few dozen companies, etc. I have found that if just go shopping at whatever on-line retail sites, can get some bad products, worse than my experience at Amazon; so, Amazon can have some trust from selecting relatively good product. It may be that Amazon can be responsive: The mid-tower case server I built supports error correcting coding (ECC) on both the motherboard and the processor; so I explained to Amazon that for their main memory sticks (DIMMs, duel in-line memory modules) they should offer ECC; they did, and maybe my suggestion helped. Still, IMHO the keys to Amazon have been just (a) and (b).

From the shopping I've done recently, it appears that a lot of retail Web sites just copy a LOT of software architecture and design from the Amazon Web site. So, we can expect that building such a retail Web site is becoming a widely, well understood art and, thus, no longer an advantage for Amazon. Indeed, the company might host their site at Amazon's cloud server farm AWS -- irony here!

Net, it looks to me like the US manufacturers and/or importers can start to do well cutting out the middleman Amazon. Ah, Internet disintermediation!!

Uh, shipping from many local warehouses? When I was at FedEx, and maybe still, shippers could just truck their inventory to Memphis and, thus, get faster, cheaper delivery to their customers -- order in before midnight and delivery before 10 AM the next day, that is, in about 10 hours. Well, FedEx and UPS could still do such -- open a few hundred warehouses, let vendors stock the warehouses with big trucks and deliver to customers with little trucks (bicycles, taxicabs, drones?). Again, a dozing if not sleeping giant here is Walmart.


Amazon has made lots of products more discoverable. But that's only one component of "help me find what I'm looking for."

Case in point: I'm in the market for a new TV. Based on my experience with prior TVs, I believe I want something with high contrast, low reflections (glare), low response time, and high color gamut coverage. Well, some balance of those criteria weighed against price. I'm new to the TV market: how do I find this (on Amazon or elsewhere?)

If I expand, the situation might seem worse. I'm tangentially familiar with two modern display technologies: LCD and LED. I know LEDs offer higher contrast and quicker response time. So I search for LED TV on Amazon. Most of the results do indeed have "LED" and "TV" in the name, and nothing on the product page suggests anything different. But look up detailed specs for that model (which takes some determination in and of itself) and it has none of the characteristics of an LED TV. The contrast is low, the response time is high, in fact it turns out it's an LCD TV! Apparently the industry markets using LED to mean LED _backlight_, which to me was misleading. So what class of TV will get me what I'm after? There are places to figure it all out, but Amazon sure as hell isn't one of them. Nor is Best Buy, Walmart, or most other retailers you've heard of. They still do an awful job helping you find what you're looking for in many cases.


Did you mean OLED? Anyway, yes there are places, and these aren't terrible:

https://www.techhive.com/article/3316544/best-tvs.html

https://thewirecutter.com/electronics/tvs/

https://thewirecutter.com/guides/buying-a-tv/

For a mail order / online retailer, visit this page at Crutchfield:

https://www.crutchfield.com/g_146350/All-TVs.html

Then click the red text "Explore Articles & Videos", just above the listings on the right side. Their TV Buying Guide has good visual explanation of LED-LCD vs. OLED, for instance.

Depending what you look for, calling them and chatting can work too.

// Keep in mind with any review site or retailer, paid review placement can be a thing.


Amazon is definitely the clear leader but both major brands and small companies could do better with a site focused to their own goods. In a lot of ways, most tech companies already do this but retail just hasn't caught on yet.


Discovery (if it's not on Amazon it doesn't exist, to many online shoppers—no, seriously) convenience (I already have an Amazon account) and confidence (yes Amazon is a shitty flea market at this point, but they're a shitty flea market with a known and fairly reliable return policy) matter a lot. Not sure how to solve those issues with a bunch of brand-specific sites.


Amazon won the US market, it hasn't won the world yet.


> Retail companies are blind to just what a shit-show their websites are

shit-show or not, when I'm buying something online I strongly prefer buying directly from the company's website over using sites like Amazon.

My purchasing pattern goes like this: I want something, I search (using DDG) the web for what companies offer what I want, then I go through the companies websites to decide on where I'm going to make my purchase.

I'm certain that I don't represent the most common sort of customer, but I'm also certain that I'm not alone. Ads are irrelevant to me (I block all scripting, so I rarely see ads), so if a business wants to increase the chances that I'll check them out, what they really need to do is SEO.


That could be hundred of small sites. Don't you mind giving your personal info and card details all over the place?


No, I really don't mind. I use one-off temporary CC numbers for online purchases.


I do not work for google facebook or any other internet company. I do however purchase online ads for my law firm. I also tried turning off the ads for a few weeks to disastrous results.

I can say the big problem in the examples in this article is the keyword selection. For example ebay advertising the word ebay to customers who are googling the word ebay is probably fruitless for the most part. Those people were already looking for ebay and would find it with or without the ad.

However if you are a lesser known online auction and you use the keyword "internet auction" or something similar, it would probably help.

This article, to me, seems to be more about the importance of experimenting and critically evaluating the data rather than an actual indictment on online marketing. With online marketing there is no clear answer: what keyword you bid on, how you target, how you write your ad copies, how your competitors are behaving all come into play. It's difficult for anyone to parse through those factor and really come out definitively as to whether online marketing is effective or ineffective in general. We can only do the smaller measurements and see if our particular ads are effective for our particular business, which in the end is all any of us who buy ads really care about.


I've had the impression that "online advertising" has been rife with fraud since its inception.

Using cloud services to cheaply farm the clicks reported by the ads seems obvious.

That we collectively turn a blind eye to it is the most disheartening part.


How many people here have purchased something solely because they saw an advertisement for it, or how many people do you know who have done that?

I can't recall myself ever seeing an ad for something I did not already know of and then spending money on it.

Whenever I have found something that I didn't already know and then purchased it, it has been because of word-of-mouth (including online comments), reviews or recommendations/features on digital stores like Steam, GOG, App Store etc.


Me neither. However HN is an echo chamber of intelligent people who aren't going to sway their opinion or purchases based on ads. It's harder for me to visualize but the majority of people out there pay attention to ads and even will convince them to purchase.

When I go to the movies, people will laugh or agree at the most stupid ads. I don't think most people educate themselves or their children about not engaging in such content. It's why those morning shows that are really just ads in disguise are still airing today.


I suppose it depends what you call an ad. I've definitely bought products based on 'independent' youtube reviewers who received free products to review.

From a sidebar ad though? Of course not, and I never will. They do get accidental clicks from me sometimes though.


> "What frustrates me is there’s a bit of magical thinking here," Johnson says. "As if Cambridge Analytica has hacked our brains so that we’re going to be like lemmings and jump off cliffs. As if we are powerless.”

Probably not, but nevertheless their efforts to polarise thinking and support the formation of echo chambers have been quite successful. While selection effect has indeed been disregarded often, in the case of CA it actually amplified the outcome.


its also very difficult to measure anything about political ads, so better keep the research to commercial ads for which data can be found


> A former Facebook engineer once said (and he’s been quoted a thousand times over): "The best minds of my generation are thinking about how to make people click on ads." I spoke to some of those best minds: economists employed and formerly employed by the most powerful companies in Silicon Valley...

Not to be a jerk, but almost none of the best minds in SV or of my generation are economists.


If you are a millennial or younger, I respectfully disagree. The "best minds" have been sought out to build out the new infrastructure in the service of the new railroad tycoons.


I'm still dubious about the implication that digital advertisement is fundamentally broken.

My issue is that the article doesn't demonstrate selection effects dominating over advertising effects for companies with no major brand identity. The examples cited to back the case - eBay (which is huge), "large" retailers in the case of Facebook ads, "major U.S. retailers and brokerages with millions of customers" per Lewis and Rao 2015 - are all established companies that have already received substantial presence. Where are the experiments that demonstrate selection effects dominating over advertising effects for companies with no pre-existing brand identity e.g. The Correspondent (sorry, I couldn't resist :P)?

Second issue: the article demonstrates convincingly that brand-keyword ads are broken, which is great. But at the same time brand-keyword ads are not (to my knowledge as a former engineer at an SEO company, so it could be imperfect) the primary kind of keyword ads. A brand-keyword ad is when someone types in "eBay" and you get paid eBay links - but the majority of keyword ads (again, this is from memory) are targeted keyword ads e.g. someone types in "fur coat" and Macy pays Google to put a link to its "fur coats" pages. Equally interesting, multiple companies can pay for the same targeted keywords, meaning you can have multiple links pointing off to different sites on the same page.

The pizzeria analogy explains why brand-keyword ads make no sense monetarily (someone searching for your brand specifically will find you anyway), but it falls apart for the targeted keyword space, where people are searching by items but not by brand.

Given that much of SEO and digital marketing are target-based rather than brand-based, I'm not sold yet on the ineffectiveness of digital advertising overall.


So 16 years ago it has been shown that advertising for your own brand name is worthless?

Yet still in 2019, when I google for "Amazon" I see an Amazon ad?

Color me skeptical.

I doubt the marketing guys at the worlds biggest companies are that out of touch with reality.

Would love to know why they do it though.


> So 16 years ago it has been shown that advertising for your own brand name is worthless.

Chanel and every fashion brand that has a reall business in selling stink, Coca Cola, evian, Mercedes, JP Morgan ... We could list them all day. In fact just about all companies that rely on brand perception. All of them Beg to differ with that. And they have market cap that backs that view.

Glossy magazines, television, fancy Cinema ads, Point of Sale, event sponsorship. Nothing online. Ever. At least that I'm aware of and who can miss their advertising without which they have zero business.

Especially consider the stunning success that is Chanel selling $100+ bottles of stink that literally has a manufacturing and delivery cost of cents each. Cost of goods sold is a little higher than that when they include the brand marketing. Without it, not doing much business. Elon Musk has achieved the same, not stupid fashion shows but he is a media event and it reinforces Tesla's brand - that's brand marketing. He's brilliant at it. It's been weeks since a huge Musk media circus, he's hired the onion writers too, must be one worth millions coming up in your favourite news source soon...


Otherwise Google will put an ad for some competitor, that many people will take for a search result, in that slot, right?


> Yet still in 2019, when I google for "Amazon" I see an Amazon ad?

It's funny, I tried the same experiment and saw no ad. Also tried ebay, no ad. I wonder how they're preventing other people from bidding that search term up.


I think your answer is in your comment. Why would the digital marketing guys at Amazon say that their advertising doesn't work and their budget should be cut? They want a bigger budget with more responsibility, not less!


Unlike most companies, Amazon can easily track ad display or click to purchase. While they still can't establish causality (you might have bought it even without the ad), it's still fairly easy for them to calculate if the ads are worth it.


When you have Amazon's scale, you can easily do geo-controlled lift studies like the ones mentioned in the articles to get a pretty good estimate of the incremental ROAS.


Increased click-through I guess, and because they have unlimited money.


Sounds similar to this other bubble where we blindly pay software engineers to create and modify software but we don't know how much revenue those software features, refactors or bug fixes generate, if anything at all. /s


You are very correct. But what I always wonder. How long can this system perpetuate?


The biggest ruse is Facebook convincing marketeers and agencies alike that three seconds counts as a video view. They justify this by saying people don't want to watch videos are attention deficit.

The truth is that very few people want to watch an ad. But if there's a strong enough value exchange with the consumer, they will. Just make effective content that's emotive, funny or offers utility.

Creatively, the impact of this is clients wanting ALL the messaging in the first three seconds of video content, which often causes the consumer to skip the rest of the content anyway.


I worked for an ad network for 6 years. The level of fraud in online advertising is staggering. It might work for some but a lot of it goes to waste, not even seen by humans.


Coming from the other end (after someone clicked an ad), I got to say: ads work well. The metric used @work is: cost of sale.

The merchant pays for each click on the ad that is redirected to his product page. What seems like a recipe for wasting incredible amounts of money on an army of click bots is working - because the merchant defines a target cost of sale for those clicks, meaning for example he expects a sale worth 100$ when spending 10$ on ads (a cost of sale of 10%).

And the merchant will set a budget and won't repeat/continue a campaign beyond those costs, so it is in the ad publisher's best interest to deliver real paying customers instead of an army of bots.

Cost of sale is of course different for each product category - clothes and perfume have huge margins (so the merchant may be willing to pay 30% of the final sale price for advertising costs), computer parts less so.

In the case of ebay and amazon and other large retailers it's common to not pay per click but for a percentage of an order's total volume (x% of shopping basket's value once an order is placed). In that case, we have to trust the retailer to deliver correct sales data to us.


But doesn't this ignore the selection effect discussed in the article? IE to use your numbers say you get a $100 sale for every $10 spent on ads. And say your profit margin (outside of ads) on that sale is 20%, so you earn $20-$10 = $10 in profit.

However, what if 3/4 of the people who clicked on your ads would have found you anyway, through organic search results or other means? Then that $10 spend only actually generated $5 in net income before ads, or a $5 loss after the cost of the ads.

It's tough to say what that number is without doing some testing, but the point is that you can't simply treat all the business coming in via ads as attributable to the ad spend.


True, you could very well cannibalize your own advertising efforts. I think that may be a problem for brands who already advertise themselves. For example, I agree it makes no sense for Ebay to place an ad for the search term "ebay" if they are already the first search result. If you have a well known brand, you will have a lot of people who will search you out directly. In that case it's a matter of running campaigns and see what sticks - if you spend 10% of your budget on an agency's ad campaign, and very few new customers turn up, you may be wasting money.

But if you have a small to medium online shop, I think it makes sense to have someone run ad campaigns for you on as many domains as possible - and pay only for high quality traffic. If you re-sell shoes from Nike, you will have a very hard time getting a click from someone who would have bought at your shop anyway, because your competitors will pay for Google PLA and other ad campaigns and anyone who is looking for a good offer will run into their ads.


Since you're taking the example of Ebay. When Ebay doesn't pay for ads, the top paid result Amazon most of the time. When Amazon also runs out of ad money, it's a less reputable site taking the top site, sometimes a plain scam.


I think the selection effect is much larger for big, well-known companies. Everyone knows eBay, so advertising is obviously going to give decreasing returns.

For smaller, lesser-known companies, I think advertising is much more effective. The chance is much lower that people will know about your product and buy it than if you spent more on advertising.


Almost all tech companies run lift studies / incrementality tests on all of the largest channels. For net new users, the incrementality is usually quite good. (for SEM-Brand and other high intent traffic, not so much... )


I kept waiting for the other shoe to drop on the #fitgirl/yoga pants anecdote. It seems plausible that such a targeted campaign could be more effective than the standard "dump a bunch of money in this set of adwords" crap. At least one executive was really certain about it. The way this section is written, it seems like we're making sport of that guy without actually knowing that he is wrong.


I wonder how much under-the-radar advertising happens here.

Good karma user: meaningful context to the thread "But now I just use $product"

Immediate response: "Yeah $product is amazing - but here's something related and a different to the gist"

The whole thing is an aside but it's in context and make sense in the flow. That kind of advertising is massively more effective than a google/facebrick ad.


i notice that with a lot of comments about cloud-related services. While effective it's also limited to a few niches


How successful companies do ads: ONLY invest in the ad if you have at least 3X ROI to cut out all the "bullshit tiny 1% improvement" ideas, and you don't run into any problems the article mentions.

eBay ran into millions of problems, because they focussed on "how could we improve sales by 0.0001%" and is the ROI of this ad 0.001% or 0.002%?


So, there are a lot of reasons to think ads might not work, and a lot of reasons to think surely market forces would punish companies who spend $$ on ads that don't work. Which to believe?

Well, reality check: do the ads you get shown, work? For me, almost never. It's either: 1) the thing I was google searching for anyway, or 2) the thing I bought online yesterday, which I therefore definitely don't want and won't want for a long time. This even happened with things like cars and house air conditioners, where someone who's recently made a purchase is the LEAST likely to want it.

I can think of a lot of reasons for ad-supported companies (which includes news journalists) to want to claim that ads work better than they do. I can think of reasons why executives want to believe ads will save them, when they won't, because actually improving your product is much harder than spending VC money on ads.


Where companies have investment, they can afford to place ads that are unprofitable. Though LV (Lifetime Value) can make an unprofitable ad profitable eventually, I question any measure of "effectiveness" other than profitability.

That said, by every measure that we make, Facebook ads for our local events have been profitable for us.


I wonder how much (in %) the 'Google tax' is these days, which is paid by businesses that advertise for their brand as keyword on Google despite being the top search result, just because Google sells the almost indistinguishable ad spot above the first result to their competitors.


It shouldnt be too hard for websites to teach their users about this: "When searching for us on google, look for our domain name in the results".


Somewhere near the very bottom of the article is this gem. Emphasis mine.

"And it wasn't because it was working for them. ... But there was one group of advertisers with a valid reason to purchase own brand name ads. Not that they were any more effective for this group, but because their competitors were "crowding them out" by buying ads that targeted the brand owner's name (so you search for "Bestbuy" but a sponsored ad for "Walmart" tops the list). This can enable Walmart to steal 20% of Bestbuy's organic search traffic"

In other words, even if a lot of people figure out that digital advertising is worthless to increase sales or whatever, they might still buy it for defensive reasons .. It's a win for Google/FB either way


This is one of my gripes with Google and not being evil. Allowing competitors to outrank you for your brand if they pay and you don't is racketeering. Allowing this is so blatantly wrong I'm not sure why it doesn't get more attention.


this mostly works because google stopped marking their search ads with a different background color and made the search page entirely confusing so you don't know what s an organic search result anymore


I can’t read the article but I think it’s starting to deflate on its own. Like when J.P. Morgan stopped advertising on google after the whole controversy of ads being shown in front of extremist content and realized it didn’t make a difference.


you can, just click "maybe later" at the bottom where it says "become a member"


I did that, and then afterwords it told me that the article was being gifted to me buy a paying member. After that I just closed the tab. It is kind of a stroke of genius, encouraging me to sign up by showing me that I'm enjoying the largesse of a paying customer. On the other hand, if letting me read the article is such a huge imposition, I guess I don't want it.


The paying member is the first author.


im not here to engage in the debate about how much we hate online subscriptions. I'm just commenting on garbage UI trying to trick you to subscribe and pay for an article that isn't really paywalled


Is there similar studies about management consulting?

It seems that most of it is just holding CEO's hand when they must flip a coin and having someone outside the company to blame. (they do it with PowerPoint)


I just want to say I love the little built in links/dropdowns within the article to expand information. Much more user friendly and smooth than using formal citations.

"The experiment continued for another eight weeks. What was the effect of pulling the ads? Almost none. For every dollar eBay spent on search advertising, they lost roughly 63 cents , according to Tadelis’s calculations." - that issue isn't related to a problem with digital advertising, but to horrible financial management


Some advertising works on me, and might be self-selecting.

The "thing x added to cart" on amazon, showing lots of similar things, and related things. At that point, I have capitulated on many occasions.

It's like giving a coupon for a drink in the pizza waiting area. (Or in some cases, showing me there's a better pizza)


If you think about it, the very line that the smartest minds of our generation are working on making people click on things is itself marketing designed by marketers to sell the prestige/status of working for a big advertising company.

That actually is genius in its own way... but just as the quants in finance during the early booms were "the smartest guys in the room, until they weren't and you realised they all were poor implementers of undergraduate statistics and jargon during economic bubble and crash", I don't think the workers for facebook/Google are necessarily that bright.

It's depressing that our economic and social system is geared towards pushing maximum consumption, no argument there, but the smartest people on the planet already self selected out of that over the last 20 years, and what you're left with is... well... marketers and advertising dressed up as prestigious tech firms talking about how great they are.


> smartest minds of our generation are working on making

Considering the deterioration in software functionality that i m experiencing the past years across the board (from superheavy web apps to mobile apps that for no reason remove features to desktop apps that function worse than even mobile apps) - i m not even sure they re employing the " smartest minds of our generation"


In my experience the smartest people don't want to work on UI's, which is probably the reason they are bad. The smartest go work on other parts of the stack, doing things like machine learning or infrastructure.

The only place where you have the smartest people making UI's are in games, they often have very impressive performance and functionality. But even in games people hate making UI's, it is just that in games people care about the product so they bite the bullet and do it themselves.

Note that I am not saying that UI is easy or unimportant, making UI's is both hard and super important which is why it is a huge problem that we can't find good people for it.


Measuring the effects of marketing started a bit earlier than Google: https://en.m.wikipedia.org/wiki/Scientific_Advertising


Has anyone ever been fired for buying digital ads? Also, there are enough examples that show that the toxicity or ineffectiveness of a technology becomes immaterial once a sufficient number of jobs (and other vested interests) depend on it.


The "experiment" you mentioned here is observational. The reality is, major digital ad platforms today (google, facebook, etc.) all provide rigorous RCT experiments. That will reveal the true effectiveness of ads.


Anecdotally, a bubble sounds right, since I know I never see an ad anywhere. Firefox + ublock on both computer and mobile, never even consider a smartphone app if it has ads. So how can it be effective?


One thing I don't understand, is why advertisers won't give me a way to tell them that I've already bought a car, so I don't need to see car ads anymore.


There was a bus company that started service from Princeton to Philadelphia. They advertised via Facebook. I saw the ad, and I bought a ticket. Sometimes it works.


I disagree with the author. Although all points outlined in the article might be independently true, making a general rule out of it is not ok. Especially modern, agile marketing teams that understand the importance of testing and learning are able to produce campaigns that generate positive ROI/ROAS.

Sidenote: Co-founder of Admetrics here. We provide an experimentation solution that enables businesses to run marketing experiments on their data at pace, so we see a lot of test results on a day to day basis.


Moral of the story: If you’re not testing the null hypothesis when measuring ROI on ads you might not be measuring what you think


Just remove the ads and allow the supporters to reward creators anytime, with any amoun.. Like the Pepo app..



Tldr: Google is a kid handing out discount pizza coupons in the waiting area of a pizzeria


I’m skeptical about one of the main premises of the article: that brand keywords don’t have a positive ROI.

Background: I took part in running millions of dollars of brand keywords for multiple companies. This is not what my business sells anymore.

I’ll explain my counterargument in two different ways: with an analogy, and with data from a project that I was tasked with figuring out whether branding ads had an ROI. I'm looking for responses that can poke holes and help me have a better understanding.

The analogy. Imagine you own a Chinese restaurant. John Doe is in the mood for Chinese chicken dumplings. John is hungry and in a rush so he gets in his car and starts heading to the local restaurant area because he heard about your restaurant. There are multiple ways to reach your restaurant (same as when you search a brand name in different ways + product A/B/C). No matter which route John takes when he is looking for your restaurant, he will have to go through one of the many roundabouts (the roundabout is the first page of the google search results). John reaches one of the roundabouts that’s right before your restaurant. There are 10 exits, some of them lead to your restaurant and some of the lead to other places. Since this is a roundabout, you don’t get to see each exit at once, but rather go one by one. Each exit has a sign that states the name of the place and a small description. The information on each sign was put up by the local authority (google), which is based on what the restaurant initial provided but it’s relatively the same across all roundabouts that lead to the restaurant. Since John is hungry and in a rush, he tends to take one of the very first exits he comes across (similar concept to the amount of traffic the 1st search result gets VS the 2nd Vs the 3d). The problem is that your restaurant is not the first exit for every roundabout (i.e the 1st result in google). For some roundabouts, the local concierge is the first exit (i.e a number of brands I worked with had the 2nd result for certain brand+product keywords as the 1st result was taken by major informational or review websites). For some roundabouts, the local authority agreed to add a new exit as the 1st one you come across that has a digital sign which changes based on what every "John" is looking for ("yummy chicken dumplings") and leads to the competition (paid search ad that always shows up before the organic results and the title/copy changes based on what someone is searching). For other roundabouts, your restaurant is 1st but John searched for your brand + "product by the wrong name", so the description of the first result doesn't reflect what John is searching for and he skips it (because Google doesn't let you dynamically change the organic title/description as you are allowed with the paid ads).

The data. We stopped google SEM brand ads for 6 months, restarted them and let them run for a few months. We noticed that when we restarted the brand ads, the organic revenue decreased. The organic + brand ads revenue also fell by about 25% VS the time we didn't have brand ads running. The key question was: Did the number of people searching for the brand decrease during the same time? If branded ads are 100% cannibalizing the organic ROI, then the organic search impressions (i.e how many times the brand's links show up when someone searches the brand on google) and clicks should have remained the same. We looked at the top organic brand keywords that were responsible for 99% of the impressions/clicks the brand got on google. During the periods that we checked, organic impressions/clicks had fallen by about 40%. So the number of people searching for the brand fell by about 40% and yet the revenue from the organic search + brand ads only fell by about 25%. If you crunch in the numbers, you'd see that we had about a 20% increase in organic + brand ads revenue VS purely organic revenue.

Last but note least... I don't have the links to the following research with me right now but it's available online: (1) competitors bidding for your brand terms can steal a double-digit percentage of your organic traffic if you don't bid as well, (2) consumers think brands are more legit the more they see their results all over the first page, (3) consumers put significant weight on the first result of the page, (4) the message brands use to get the user to take an action can have a double-digit percentage impact on whether the user will that action or not. Bonus: the high CTRs from the branded keywords help overall google ads account health/quality which helps you get cheaper ads from Google, better positions, etc.


Honest question here...

I thought analogies were supposed to be simplified to ease understanding. This one is complex and hard to follow -- is that because the underlying idea is so complex that even the simplified form is complicated?


Maybe. It could also be because I did a terrible job at explaining it.


Maybe this is just a generational thing, but I still have never clicked on an ad. I hate ads. I don't know anyone who likes them. I don't know anyone who has intentionally clicked on them.

I have literally never met anyone who places any value in advertising at all. Everyone hates it with 100% of their being. It is the garbage we all just sort of accept exposure to as some sort of fee for existing online.

Who are all these people that subverted technology and turned it into advertising-tech?


The kind of person who clicks on ads also buys stuff. The negative, "if you don't click on ads, you don't buy stuff," may not be true in the strictest sense, but may be true for so many ways that matter.

Facebook is full of ads, you know Facebook users. Instagram has the most effective ads on the planet, maybe the only inventory on Earth where brand advertising works. You know plenty of Instagram users. YouTube's ad value is an open question, but I think their brand advertising also works. You can't block their ads in the apps, which is how people use them.

Sure, I get it, you're talking about banner ads. The kind of person who clicks on banner ads buys stuff!


> The kind of person who clicks on ads also buys stuff.

Everybody who has money buys stuff. People that click on ads are probably more easily persuaded into buying shit they don't need. I don't have any data on this, but it's highly questionable whether an ad-clicker buys more stuff in general.


Yeah I think Facebook and Instagram ads work great because people are there trying to fill empty time. They don't mind where it leads them. Whereas on YouTube they often want to watch that particular video and they will view advertising as a greater annoyance.

In my experience (helping a family member with a small niche e-commerce store) FB advertising works. To the point that if the ads stop, the revenue stops almost entirely. We tried it last month when stock ran low and sales dried up until the supplier came through and the ads started again.


I have clicked on ads.

I wish ads were better or more relevant, I find myself spending unreasonable amounts of time looking for things which should be more easily found - a problem which could be solved with better advertising.

You could advertise books/shows/movies to me (based on your current search, your wish list, your past purchases, you might be interested in ...) because I'm certain there are plenty of books I would be interested in which I don't know exist ... but you would have to actually have a good model for what I would like and not just some NYT best seller / top 40 / whatever crap is popular and overpromoted.

The problem there is I'm generally only going to be interested in long tail items, and those are much harder to target and often nobody is interested in promoting them.

If I'm searching for restaurants or coffee shops, likewise I would be happy to see paid advertisements along with organic search results.

If I'm reading an electronics design blog, I would be happy to see ads for electronics tools, new components, suppliers, etc.

There are lots of potential ads I would click, many I wouldn't mind seeing at all. The problem I have with advertising is that what I get exposed to most is either completely irrelevant (become a member of AARP today!), promoting obvious products (drink Coke!), or promoting shoddy products or outright scams.

Here's an example of a site with sidebar ads I appreciate: https://www.eevblog.com/

>Who are all these people that subverted technology and turned it into advertising-tech?

Microsoft who started bundling "free" things with Windows to squash their competition. Everyone else who had to find a way to compete with them (and in turn everyone who wanted to compete with those companies, etc). Every customer who expects things to be "free".


> I wish ads were better or more relevant

I honestly don't. I actively don't want ads to be tailored to me, and not just because doing that requires spying on me.

In the past, most of the value that ads have given me have been as indicators of the target audience for content. For instance, I can leaf through a magazine I've never heard of and know, based on the ads, whether its a magazine I'm likely to enjoy.

Targeted ads completely destroy this value proposition, leaving ads without much value to me at all.


> there are plenty of books I would be interested in which I don't know exist ...

> The problem there is I'm generally only going to be interested in long tail items, ...

Yup. For that problem, did some original applied math based on some advanced pure math prerequisites and wrote the software for the math and for the corresponding Web site -- software appears to run as intended. Need to add some data and do an alpha test.

So, I am regarding your problem as a need for better Internet content (yes, including information about books, etc. not strictly ON the Internet) discovery and recommendation, and I'm regarding those as special cases of a much more general approach to Internet content search.

My work is to give you the content with the meaning -- artistic, utilitarian, political, technical, etc. -- you have in mind. So, I believe I've made progress on the meaning of content; a key here is some of the pure math.

Yes, my techniques should do much better at getting you the meaning YOU (extreme personalization) want than any top 40 style lists.

My view is that Google and Bing do REALLY well on about 1/3rd of the problem; I'm going for the other 2/3rds. Where Google and Bing work well, my work is NOT better. My work should be better in the 2/3rds.

I intend to announce an alpha test here on HN ASAP. Will look forward to the HN reactions.

At least initially, my site won't be very comprehensive. I intend to concentrate initially on fine arts, finance, nature, and a few more.

Yes, my Web site will be free to users and ad supported with my unique (methods and data) and hopefully especially effective ad targeting.

Yes, my work stands to be relatively good on user privacy: There are no logins; I make no use of HTTP cookies; and search results for a user have nothing to do with any history about the user; e.g., any two users doing the same search at the same time (before I update the data, say, say once a week) will get the same results.

Maybe someone will like it!!


I’ve first read posts about your website many months ago, and I’ve been intrigued ever since. Could you share a planned release date, even if approximate and preliminary?

Also, it’s seems that your product has been “almost ready” for some time now, just out of curiosity, what are the main blockers?


I got interrupted by unpredictable exogenous events. Somehow when I get the last one handled, some more come along.

None of these events have anything to do with the project. The project is in good shape, and the work on the project that is uniquely mine has all been fast, fun, and easy.

I had a motherboard fail. I moved. And many more.

I better understand the advice to entrepreneurs -- "Never quit". Well, I don't want to quit, and I don't have to. Actually now my bank balance is growing nicely.

Most recently I've been setting up my new office -- it was a lot of work but looks good, efficient, functional, etc.

I'll get the nonsense out of the way and get back to the work.

The work to do now is reasonable. What has not been reasonable are the unpredictable exogenous interruptions.

Thanks for your interest.


Not that many people click banner ads. Banner ad click-through rate in North America is about 0.14% https://www.mediapost.com/publications/article/290285/north-... 60% of those clicks are mistakes https://www.mediapost.com/publications/article/268266/60-of-... 1/3 of clicks are by bots. https://adage.com/article/digital/ad-fraud-eating-digital-ad... 8% of users account for 85% of all banner ad clicks https://news.ycombinator.com/item?id=2101163


When people say that advertising doesn't work on them they are generally only focused on being immediately motivated to action by the ad. However advertising serves a wide range of functions beyond that. No one sees one Mercedes ad and goes out to purchase a $75k car. That doesn't mean that Mercedes is stupid for still buying TV ads. The ad is instead meant to do things like keep consumers updated on the latest product line, establish the brand of the company, and to keep that brand in the back of consumer's mind when an eventual buy decision does come up potentially years down the road.


Aspiration is a large part of advertising. It's not just that you won't go out but that Mercades, most of us never will be able to afford one, but we all know its a luxurious product, a sign of wealth and 'doing well'. That's in large part because of the brand image, if you bought the same car with a Ford badge would they be able to charge as much?


Yes, and it would be good to try to measure that effect also, and for that the statistics and optimization stand to be more difficult and advanced. E.g., the main input is not just some ads and clicks but a stochastic process, that is, random variables indexed by time.

Uh, go measure something and get a number. You now have the value of a random variable. The sense in which the number is random or unknowable in advance, unpredictable, independent of something else, etc. is left open. Collect such data once, say, over 3 months, and now have a sample path of the stochastic process. Do it again and get another sample path, etc.


I never click on ads either but when I see an ad often enough (even if I don’t pay attention) my mind gives that product more credibility.


That effect seems highly relative to the context in which you see an ad, and I wouldn’t be at all surprised if it was intentionally exaggerated when studied. Certain contexts increase credibility with certain people, others decrease credibility.

What it does do is actually put the product in front of your face. People won’t buy your thing if they’ve never seen or heard of it. So I agree there’s value to ads even if people don’t click on them in that moment.

That doesn’t mean their value isn’t inflated.


>I have literally never met anyone who places any value in advertising at all. Everyone hates it with 100% of their being.

I like ads -- but only if they're relevant to my interests. There lies the problem: 99% of all ads are not relevant to my interests. For online ads, 99.99% of ads are not relevant to me. So, I use a DNS blocker to filter out ads.


> For online ads, 99.99% of ads are not relevant to me.

This is what pisses me off about ads based on user tracking and surveillance the most. Google (and others) have been building very detailed profiles of us for two decades now and the ads still suck.

The ads that work are the ones that pop up when you search for a particular topic (e.g. "plumbers in austin"). They don't need a user profile to serve those.


I like ads if they're relevant to my interests AND they match the mental mode I'm in at the moment. If I'm flipping through an outdoorsy magazine and I see an ad for a neat new camping tool, I might be happy to have seen that ad. If I'm perusing a photography website and I see an ad for a cool new camera, I might be happy to have seen that ad.

I'm not happy if I'm reading a tech blog and I see ads for a car I was researching yesterday. I'm not happy if I'm checking my local newspaper's website and I see ads for the necklace I just bought my wife. These are like the non-chill guy who loudly approaches you at work, "HEY I HEAR YOU'RE LOOKING FOR A NEW JOB!".

Context is important.


The other problem is in order to figure out which ads are relevant to your interests, advertisers have to collect, store, and analyze tons and tons of data about you. Personally, I'd rather see ads that are not relevant to me.


> So, I use a DNS blocker to filter out ads.

If everybody used a DNS blocker to filter out ads, would online advertising exist as a business?


>If everybody used a DNS blocker to filter out ads, would online advertising exist as a business?

Absolutely. Companies would get more clever about cloaking advertising with inscrutable domain names that's hard to filter with regex. Youtube is a good example of ads that are hard to block using pure DNS. (But that doesn't stop people from trying new variations of regexes for pihole that youtube eventually breaks.[0])

The other technique is native advertising. (But native ads are actually more "relevant" so somewhat more tolerable and more people would actually pay attention to them.) E.g. I just saw a Linus Tech Tips (the computer tech channel) and the pre-roll ad is for D-CON mouse traps (not relevant to me since I don't have a mouse infestation that requires rodent traps) or girls dolls[1] -- but the native ad is Linus acting as spokesperson for the Ring Doorbell Camera Kit[2]. That's more relevant since it's a techie gadget. I won't buy the Ring kit but it's more relevant than the mouse trap ad.

[0] last time I tried many of these DNS regex ideas, youtube stopped working: https://www.google.com/search?q=pihole+regex+block+youtube+a...

[1] ads for girls dolls probably ignored by 99% of audience demographic of Linus' video: https://imgur.com/a/gPcxOJ3

[2] https://youtu.be/hiLlNzxDfAg?t=19m12s


Sure. The ads don't have to come from a third party.


If you really do like ads, there are plenty of platforms that will let you input your interests and customize your ads — Facebook, google, and I believe even Hulu will let your do so (I think there’s a 3rd party service called AdChoice or so that will do the same across smaller networks).

Something tells me that still won’t be enough to have you undo ad blocking...


> I don't know anyone who has intentionally clicked on them.

Hi there! Glad to meet you. My name is Jeremy!

I click on ads when I see something that makes me want to click on it. Could be a retargeting pixel picked me up after I left some random ecomm site after not buying (but still intending to), or more likely a new direct-to-consumer brand that looks appealing (allbirds, freshly, barkbox, etc).

I don't hate ads. I don't like ads. Ads are ads. If I didn't get ads, I would really have no way of knowing that something out there exists that I had no idea I might want.


You have to keep in mind how cheap advertising is. An ad campaign that affects one in a hundred thousand can be successful.

In some areas, you'll find a ton of billboards for personal injury lawyers. Right off the bat, maybe only one in several thousand people is a potential client, and it's totally irrelevant to the remainder. Of the relevant population, most of them have the common sense not to hire a lawyer purely based on an advertisement. But those billboards are still worth it. They know because they ask people how they learned about them, making it simple to calculate their value.


I'm not sure what generation you're a part of but I appreciate ads when they actually tell me something I didn't know about that I do want to buy. For example I've been shopping for beds and dont mind ads for brands I hadn't heard of. Some of them I would have bought had they been in my budget but this to me isn't so much a problem with ada in general as it is about as targeting.


If I'm diving into buying something like a bed, I'm never looking at regular advertising. I'm trawling through forums and old message boards, looking at sites that do direct sales, reading reviews, looking at pictures, going to an actual store to touch and see a thing. Advertising is a skewed view of something I want to buy where they try to convince me it's 110% beyond my wildest dreams and expectations. It's not, never will be. I just want something that's about 80% there and to confidently know it's good enough.


I’m way past accepting ad-network ads. If an ad shows for a product I’m really interested in I’d rather google it on a different browser/device than click the ad. But mostly I’m disappointed that the company in question even uses ad-network (ie tracking/targeted) ads.

(I’m from the 70’s and TV didn’t have ads when I grew up, that could make a difference I don’t know?)

I want to be shown no ads or ads for products completely irrelevant to me because seeing (well-)targeted ads makes me feel watched and tracked.


> I appreciate ads when they actually tell me something I didn't know about that I do want to buy.

I can't remember the last time I even saw an ad that did this (at all, not just online).

Oh wait, I lie, I do remember -- ads for electronics and computers in the technical journals of old used to do this, because they included actual information about the products they were selling. I haven't seen a useful ad in decades, though.


Annoyance is one thing.

Weaponization is another.

Can Ads Read My Password?: https://news.ycombinator.com/item?id=20638662 for example. Malvertising for another. Fingerprinting...


The only ads I ever click are from sales flyers that I have signed up for that show up in my email inbox. Those are genuinely useful.

Display ads? Meh. I find that they generate more distaste for the advertised service in me than anything else.


It's not really generational; people have always hated advertising. They hated it in the newspapers, on buildings, on TV, before movies, inside of movies, in magazines.

I don't really see advertising in general going away short of legislation preventing it; that doesn't mean that online advertising will always be as profitable as it is now, but there's a question of "where else will people advertise?" People advertise where people are; online advertising will lose its value when people spend time elsewhere.


I have clicked on an ad now and then. I can't remember the last time, though. Probably cars, but of course I can't buy a new car every day.

The thing is, though, if something is truly new to me, even if it seems like just the thing, I'm not going to buy it without doing market research. It's ingrained in me that anything that is brought to you is almost certainly garbage.


I keep ublock on all the time except on some sites. Sometimes, there is a worthy ad (e.g. one month free audible, cause I visited the site).

I don't resent ads, I am totally fine with them, and if they help sustain some site I use, I am happy.

The problem is when they are taking over the whole experience.


I have never clicked on an ad, and I can't imagine anything that would get me to be willing to click on an ad.

But I don't hate ads. I only hate the tracking that comes with them.


> that subverted technology and turned it into advertising-tech

What actually happened is that technology replaced the publishing industry. Publishing always had ads.


> but I still have never clicked on an ad

Do you use Instagram and follow accounts on it? If so you're clicking on ads.


But, you like accessing content for free, correct? That content doesn't exist and then ads are layered on, the context exists BECAUSE of ads. Like, no one would produce the content without the plan to make their money back via ads.

This is how mass media has worked from the get-go. Radio stations were built by advertisers for the purpose of advertising. Entire genres of popular music wouldn't have happened otherwise.

Online advertising did not create the notion of advertising being the predominant media funding model.

And, just because you'd rather ads not exist, it doesn't mean there's something "evil" or whatever about a business promoting itself. I'm going to guess that if you ever find yourself needed to market a business you'll be happy if there's an option to advertise effectively.


> no one would produce the content without the plan to make their money back via ads.

What is your plan? You just produced content, on a site with no ads, and no links to other ways to capitalize off it. I'd argue most content is created by people who just want to share something they are passionate about. Maybe a lot of it is low quality, and "you get what you [or someone else] pay for" can apply, but a world without ad-supported distribution models would not be without content.

> Radio stations were built by advertisers for the purpose of advertising

Radio stations and other traditional mass media also require substantial investment and resources; putting a web page on the internet does not (unless we make it, by putting all our "pages" on a couple giant sites, who then need revenue to provide those services, hence serve ads).


> But, you like accessing content for free, correct?

Meh. The best online content's fully paid, donationware (Wikipedia), or simply free. 100% of the ad-supported stuff could go away tomorrow and my quality of life would suffer not at all. Hell, might go up. Meanwhile spyvertising-paid "free" services & software are sucking the air out of the room for paid and open-source alternatives (and protocols—god is that ecosystem bad for protocols) alike, for a variety of things I might like to buy or use or contribute to.

I don't get the "but think of what the Web would look like without ad money!" doom & gloom. It'd be fine. Go ahead, outlaw them. I do not care even a little.


Your post is literally the content I'm reading that you claim no one would produce without ads, and it's unsupported by ads.

And again (I feel like a broken record on this site), that's a totally inaccurate history of the internet.

Content arrived first, THEN the advertising companies arrived.


Hacker News is not mass media. Plus don't forget Y Combinator funded many ad-based platforms. HN isn't free either.


A fair point.

So I see two takeaway questions: would we be fine/better off without mass media funded by advertising(it's obvious what my answer to this would be since I don't generally listen to it or watch it, though I acknowledge it going away won't likely happen).

And the second, would content we like to consume/ be worthy of consumption be produced anyway, and my contention is that it would still, just like it did in the past and continues in the current (some free, some paid for), as can be seen in the history of books, early internet, street art, leisure, bloggers, hobbyists, cinema, documentaries, etc.

There might be a third point of mine, which is that we're actually suffering from a glut of content and competition for eyeballs: so to me, worrying about that content disappearing is a bit like worrying about dying of thirst while drowning in a freshwater lake.


I don't know, really. I don't want to go back to a time where artists struggle to eat, to make a metaphor. Independent creators are using advertising revenue now too.


> But, you like accessing content for free, correct?

I'm really not sure about that anymore.

I pay for The Athletic, I was hesitant at first but now I really enjoy getting access to top quality sports articles with no ads and a nice clean experience.

I pay for Google Play Music (for however long that lasts) and I'm really happy I can just listen to music without needing to hear more fucking ads in my life.

I support a few Youtube channels on Patreon because the advertising money on Youtube isn't enough for them to cover their bills. At this point there's a good number of channels I would rather pitch a few dollars at each month than have to sit through ads (which are adblocked anyway, whoops) and have their content threatened by what Youtube determines advertisers care about.

I pay for Netflix and never have to watch ads (so far) while watching TV. Whenever I watch live TV it drives me crazy how many breaks they take to show me the same stupid commercials over and over again for stuff I will never buy.

You see it with online sports packages that don't have the rights to show TV feeds online -- so when it's time for commercials, it just switches over to a silent image saying "Commercial Break in Progress". I pay $20 a month for DAZN and I'm not sure how much longer I can stand watching the awful commercials that keep getting shown at every break.

I donate a small amount every once in a while to Wikimedia and in return we all get access to a free encyclopedia that stays eternally relevant without advertising.

We can live in a world where we pay for content and be happy. We can live in a world without advertising. It's really not that bad paying a little to get a much better experience.


Actually, that's not (historically) the case. From The Attention Merchants (a great book, by the way), page 12:

>"Day's idea was to try selling a paper for a penny...he felt sure he could capture a much larger audience than his 6-cent rivals. But what made the prospect risky...was that Day would then be selling his paper at a loss. What Day was contemplating was a break with the traditional strategy for making profit: selling at a price higher than the cost of production. He would instead rely on a different but historically significant business model: reselling the attention of his audience, or advertising. What Day understood--more firmly, more clearly than anyone before him--was that while his readers may have thought themselves his customers, they were in fact his product" (emphasis original)

His paper ended up being the New York Sun.

Just something to think about. It wasn't always like this.


Actually, I'm aggressively looking for higher quality content that I can pay for, like (e.g.) nzz.ch for news. I was also a Google Contributor subscriber, before it required an opt-in for site operators.

What I would really like is to pay for the Google Feed (aka Google Now) on my Pixel instead of having to ignore the ads that have recently started to show up there.


Does Google Now still not respect "I'm not interested" flagging?

I've tried to use it many times, but I'll keep seeing the same stories I've marked as not interested. One easy example is any Marvel release. I'll say not interested in "move title". Then the same story will pop up in the Marvel category. I'll repeat the process for Marvel, and the same story will show up as entertainment, repeat until I close the app.


I've had good results from consistently tuning my feed over the last few years, particularly by excluding low quality sources altogether.

I have seen the phenomena you're talking about though. For me it might be a political scandal that I mark as uninteresting, which then shows up again under some peripherally related category.


for some reason, they think I love baseball, so I get a ton of baseball alerts. I need to accept notifications to the Google app because that's how I auth to gmail. Pretty stupid that the same app sends necessary and completely useless alerts, but I'm sure that's intentional.


Advertising isn't the big problem (IMHO), it's the tracking and surveillance. We give up too much for what we get back.


I literally just tried to order some pants on the internet, and I couldn't because the retailer's site broke when interacting with my ad blocker.

I don't care what conditions someone wants to put on using their website, per se, and agree they have the right. The problem is, that I can't easily selectively interact with the part of the internet that isn't polluted by unreasonable advertising.

The evil part is the mixing of the unwanted or dangerous ads with the general internet. If it was segregated so you could choose which area you wanted to be in, then it would be genuinely voluntary.


> Online advertising did not create the notion of advertising being the predominant media funding model.

True, but online ads did create the notion that spying on everyone should be part of the business model. That's what I object to. If the price to make that stop is that there is no more "free" content (scare quotes because it's not really free), I'm fine with that. I don't think that's the price, though.


This is true for newspapers, pro YouTube channels, etc. But even today, the majority of internet content is created by people for free - this includes comments on HN, Reddit discussion, original Facebook posts, amateur YouTube content, and much more.
