Update: This is not something Google is testing. The WebmasterWorld member sent me a screen shot and it has been that way since at least 2004. So ignore this post.
A WebmasterWorld thread reports one person seeing the display URL of an AdWords ad showing up above the ad's title and description. In fact, this person is noticing this ad behavior just for the premium ads, not the ads on the right hand side of the page, only the ads at the top of the page.
I personally cannot replicate this on a Mac or PC, using IE, Firefox or Safari. So I emailed this person, asking for a screen shot. This, of course, can be some form of malware infecting the user's browser or it can be some type of test Google is running.
I decided to "photoshop" what this might look like:
Clearly, this looks a bit weird, so I am anxious to see how it looks like on the forum member's screen.
