I’ve pointed out product extensions before as a great way to increase AdWord effectiveness. Here’s another example of how powerful they can appear in relation to a growing number of product photos in the limited ad space Google provides. U.S. School Supply not only gets the usual blurb with the usual link, but five additional links, photos of product and price listings… all for no difference in the CPC (cost per click).

Oh, and did you notice the stars in the lower right corner, next to the Pottery Barn ad (PBTeen.com)? That’s another neat little trick for increasing conversions from AdWords. It’s called “Seller Rating Extensions” and Google claims they get an average 17% higher CTR (click through rate) than ads without them. You can read more about them here.
