Maybe I'm late to the party, but this morning I noticed one of my sites is showing Adsense - with an image of the Google logo in the "Ads for Google":
The graphic is linked to a landing page which invites people to sign up to AdSense or Adwords.
Sets up a feeling of unease - giving Google credit for the ads is one thing, but now they seem to be testing out how to more aggressively get new publishers and advertisers - and without having to go through the affiliates system they set up previously.
More disturbing, it's inviting viewers to ignore the ads and click through the Google logo.
Would be nice if Google were to respect publishers a little more in this area, and focus more on delivering the ads for the advertiser's benefit, rather than trying to push promoting Google for Google's benefit.
It's not as if AdSense has any serious rival, does it?
