Google AdSense has been busy testing new AdSense units this weekend, with two new formats spotted in the wild.
The first comes via a DigitalPoint Forums thread, where dozens of publishers are noticing related words at the bottom of their normal AdSense units. Here is an image of one ad in action. Notice the related words at the bottom of the ad:
The second Google AdSense test is a “show more” link found at the bottom of Google ads. I found this at iBrowseHere.com , and here is a screen shot of it in action.
Clicking on the “Show More” link takes you to a new page with related ads.
In a related now, there was a outage that took down all Google PPA ads over a 24+ hour period this weekend.
