I recently signed up for Google Checkout, and I noticed they've placed a Google Checkout icon next to my AdWords ad. I have two campaigns that are trending in opposite directions for CTR. The data is preliminary, but I was wondering what other people were seeing as a result.
I wrote about this back in February, Google Checkout Gets Even More Annoying. Basically what I've seen is at this point the checkout icon gets you nothing but a lot of curiosity clicks.
