I haven’t seen this in my own browser yet, but MG Siegler at TechCrunch reports that Google Suggest has added advertising (see Google’s official post here). It also talks about personalization, but I’ve been seeing that for a while, so I don’t know that there’s anything new on that front.
In any case, here’s an example of a suggested ad, courtesy of TechCrunch:
I’m sure Firefox extensions like CustomizeGoogle will soon blog these ads, if they aren’t doing so already. Granted, I can hardly blame an ad-supported service for pushing more ads–and in this case the ad is actually a relevant result, independent of the fact that it’s sponsored. In fact, it’s the top-ranked organic search result for south park episodes. I imagine the feature will be considerably more annoying when the sponsored links are more typical ads, but probably not enough so to incite people to install ad blockers. Google seems to know how not to push people too far.
