Here is an interesting Google test I came across today. It looks like they are testing putting small icons beside the URL in some ads. Here is a screen shot:
Google is always testing changes like these to a limited set of users to see what affect they have. My guess is that these icons will increase the click-through-rate on these ads. There have been some other reports from people seeing these as well, but my screen shot is the first I’ve heard of a US based search showing these results.
I’m sure if these icons do increase click-through-rates, publishers will like the addition!
