Google is testing a new format for the product listing ads, Google AdWords shopping ads, at the top of the page. The format they are testing is a scrollable version.

Sushan Sharma captured a screen shot of it in action and posted it on Twitter. Here is that picture:

Earlier this year, Google started testing expandable product listing ads that opened up to 16 ads on a single page.

The new scrollable version, I don’t think we’ve seen yet. I prefer the scrollable version of the 16 listings one.
