New Adsense ad format spotted again

It was just a few days ago when we spotted a new format for ad units that Google Adsense was testing. It included a new feature called the ad scroller or ad slider that lets site users navigate through the ads using the Up, Down, Left, or Right arrows (screenshot in the link above).

A few minutes ago, we spotted again here on our site a new ad format that Adsense might be testing. This latest format includes four (4) units of Button ads (125 x 125) — two (2) units placed side by side and two (2) more below it.

The new format is a welcome deviation from the traditional ad formats that Adsense has long been using. But the question is, can it increase the click-through-rate (CTR) of the ads?
