I know this advertising campaign isn’t perfect, but I have to wonder if Google isn’t digging too deep. They’ve let advertising dominate their search pages so their page becomes less valuable to the user and advertisers get less value per dollar paid. Where the original concept was to put only a few relevant advertisements up which users would actually be interested in, now they pile on advertisements thick and deep and I rarely find them valuable. At some point this has to affect the ROI for advertisers.
