Sponsored search listings are forever changed at Google.
While not officially available throughout the entire Adwords network, expanded product search results which include images have been spotted in online jewelry store Blue Nile's sponsored listings. Google has been using these "plusboxes" in its organic results for quite a while now with video listings, but the fact that they are now appearing within sponsored listings is a major development.
Users must select the "Show Products from BlueNile" link to see the images and their corresponding links. Over time, one could assume that other advertisers will be able to display their individual products in the same way, but again, there has been no formal announcement on when that might happen. Overall it is a very elegant way to present the "Universal" content the Web has heard so much about.
