I have checked several sites today, but I couldn't find anything. There is showing "Ads by Google" in all sites!. It may be some error!
It would be nice if someone posted a screenshot of this instead of saying "my site does not show that"...etc. By tomorow this thread will be 10 pages of gibberish. I'd like to see a screenshot because there is nothing on the adsense blog about any experiments or beta testing new adsense formats. I know premium publishers can do a whole bunch of good stuff with there adsense ads.
Well the post I linked to, have posted some screen shot as well. That is not photoshoped at all. I have seen the change but not on many sites. According to the response it is now clear that Google is experimenting to remove Ads by Google.
Ads by Google text removed on almost all adsense ads for content.. Instead ad choices appear.. Check on digitalpoint forum itself.. For link units, ads by google still appears..
