Adsense Ad Formats

Most adsense experts believe that the ads on your website have a high probability of getting clicked if they blend in with the rest of the content of your web page. Factors such as color scheme, font size and type, and the appearance of your ad should match your web page. Text links should be blue so they will look more natural. Also make sure you remove the border and make the adsense block background the same color as your site is.

we generally recommend to use text ads and not banner ads. Text ads blend very well with the content of the site and it's displaying more ads then just one banner ad. However, text-dense sites may actually do better with image ads. If your site has very few graphics, you may want to balance it out by putting image-based ads. In the monotony of a lot of dense written information, image-based ads and graphics provide what’s called visual relief. This can also prompt clicks. The best performing ads are the 'rectangle' ads, the large(336x280) and the medium(300x250) most adsense users report that those formats receive higher CTR, they are the best choice try them.
