Has anybody noticed already? I have noticed it today for the first time in one of my blogs. The AdSense is showing a text box and submit button asking visitors the topic of Ads they want to see. Don't you think this would result in more clicks?
Google is continuously showing the Ad in this blog: Web Bulletin
I wonder, if Google is confused to determine the theme of the blog and that is the reason behind showing this type of AdSense? Or, it is a new Ad type?
