Sergey Alakov spotted another Google test, this one is around Google AdWords ads showing an image in the ad block pulled from the landing page's content. Ginny Marvin has a statement from Google about this, saying Google is always testing things.
Here is the screen shot from Sergey:
Google told Search Engine Land:
Weâre always testing new ways to improve our experience for our advertisers and users, but donât have anything specific to announce right now.
Google does put images in AdWords ads, but I don't believe they've done so dynamically from the landing page's content.
