Google AdSense Optimization Tips for maximum CTR
- The best performing ad units for AdSense are 160×600, 336×280 and 300×250. For text only ads, you should go with the 336×380 format but in all other situations, 300×250 may be a better format since it is most popular among advertisers and also supports rich media. 160×600 can easily fit in the sidebar of your blog.
- Web visitors have a very short attention span and majority of them may simply leave after a quick glance. Their eyes follow a F pattern so you can get good results if the Google ads are placed in the areas colored red on the heat map. Sidebars and leaderboards at the top are often ignored.

- Make AdSense units border less and that the background color of the ads matches with the background of the page.
- Text ads are better than image ads. Like before, people are more responsive to text than images. In a way it is considered as a part of the online document and is more clickable.
