Well I have updated my sites to removed all the images next to my ads. Example http://www.3d-tutorial.com Since I removed the images next to the ads I've been seen a 94% drop in earnings. If you scroll down you'll see an ad with a custom border. This was approved by Google, but its not helping at all. Anyone have any suggestions. I think the ads are layed out pretty well, but I've hit rock bottom with CTR, any suggestions?
Now that you don't have images next to Ads, everyone is clicking on the tutorial links where you DO have images. Which is good for your site, but I know you want them to click on Ads. I would remove the those small images and in the block where you have text about 3D tutorials, put a nice big image/picture there. Then, the next thing down is your Google Adsense. It's far enough away that Google won't have a problem. This is my suggestion.
If you find they are not clicking on the right side bar adsense I would remove it and an ad on the upper banner spot that is currently empty.
