Hi, One of famous Indian Tech Blog is Labnol.org ( Love It ) ! I have seen that on post pages, for example say : http://www.labnol.org/internet/smartphone-study/19533/, the Google Ads displayed below the post looks different ( rather awesome ). When I checked the code, it seems it is different from what we get from Google Adsense. Is this some kind of policy violation ( changing of code ) or benefit of being a premium adsense account holder or something else ? Is second is the case, why does Google not allow us to have that design. It will help to boost revenue for both Google and Publishers !
That is the ad served to a premium publisher, and premium publishers are chosen by invites depending on the traffic to their sites.
