Jensense reported that Google AdSense is starting to test some sites with unbranded ads being displayed. As of right now, only premium publishers can unbrand the Google AdSense ads and use their own format, but there are not that many premium publishers out there. It takes some 20million odd pageviews per month before being able to apply for that status.
I’m not exactly sure why AdSense would start unbranding their ads, but the only reason I can think of is to attract more clicks to drive more revenue. I often see AdSense ads and think “oh great, more ads, not clicking those…”, but maybe having an unbranded system would give them the ability to stop that mindset of Google Ads for people, such as myself. I hope to see some better testing and progress of this unbranding from AdSense.
