Barry Schwartz at Search Engine Roundtable has a nice item on Google testing a new system letting those who see its AdSense contextual ads change them on the fly to related
topics: Google Beta Tests New AdSense Ads.
Pretty slick — Barry’s post also linked to this example site you can play with the “Change To Ads”
feature.
Two years ago, Google rolled out a somewhat similar Related Searches feature for AdSense ads that
it pulled within a day. Why? The implementation of that feature drove people off an advertiser’s site and back to
Google. This new implementation doesn’t and so should be far more acceptable.
