I’ve always been a big fan of the Ask3D SERP UI. It looks as though Google is testing a layout along those lines…
Danny Sullivan wrote about AdWords + Video, last month, with a mockup of what it might look like, but this layout is a bit different. My good friend and fellow SEO consultant, Adam Moro, spotted a results page with three video results appearing under the AdWords ads in the right column… So, they’re not AdWords video ads, but they are actual Google “Universal” video results… appearing more along the lines of Ask3D.
I haven’t been able to reproduce the results page, but Adam has a screenshot posted on his blog.
