Google has this infatuation with brands. I'd like how these display and if there is an opt-out feature. Amazon is loaded in Google's search pages everywhere, and I definitely don't want Amazon's logo appearing on my site anywhere!
Started seeing these on one of my sites almost 2 weeks ago. I would say almost 1/2 of my ads have this because I'm opted just into text and in a very fashion brand space. Hasn't helped or hurt CTR rate so far. I also get 90x90 of specific products that are semi relevant to my content.
You know, being a noob, this thread led me to a site, which led me to twitter, which led me to netmegs site, which gave me a huge laugh (hint: ebay adwords...thanks, you made me spew beer all over my keyboard.)
Now today I am seeing versions that have the 90x90 image as a layer behind the text ads. It used to be the text would be right aligned, but now the text is left aligned creating an experience where there are 2 layers on to top of each other. These tests are ridiculous. I've seen over 25 text variables in the last 4 months and not 1 has been successful by Google. Meaning none of the test ever get "fully" implemented. Waste of their time and poor experience for visitors resulting in less clicks for publishers.
G has been experimenting with imagery in "text" ads since the day it rolled out the new units. Some day the whole text ad will be an image graph, that's my guess. 90 x 90 might be an improvement though. I'm thinking most of what I've seen in the past was smaller but never actually got out my micrometer. I think their use of favicons was the most effective use of imagery on my sites because I've got icons all over my site so was sad to see them move away from that. This composite ad format could be beneficial if they ever get it stabilized. It's tough designing decent looking and effective pages to hold ads when the ad format keeps changing.
