Im in process of re launching my site and placed some adsense ads on some listings and on my footer. I'd appreciate some feedback on the placement I used and colors. http://www.autogearbid.com/auctiondetails.php?itemname=Chevy-Camaro-RS-Rims-and-Tires&id=3
You should use back color for the url link. And on the footer ad you should replace the background gradient with a solid white background. IMO you CTR will be higher if you sidebar ad is placed on the left, and I guess the CTR for your footer ad will be close to 0, it should be above the fold.
Then again, you may not want to be too aggressive with the placement. However, I do think you may want to move the right block to the left.
I see NONE of the 3 Google published successful formats and also NO ATF placement any reason why you want to cut down into peaces your adsense revenue ?? as a general rule: if advertising success and revenue UN-important - why place ads at all ?
since the update of adsense policy you can try put more link unit on it. in my case, I have CTR being up.
