I bought an E-Book a few weeks back. I was feeling desperate. 100 bucks down the hole. Anyhow, here was a tip to increase CTR. But isn't it misleading? The first part of the image is obviously the ad, while the rest of the links are the sites navigation. Against TOS?
Plus Adsense links should be different somehow from the link-style of the site itself or at least bordered so they can be easily differentiated... Don't use it, instead reconsider your ads style and placement for better revenue and work for more traffic....traffic is the key for better results.
