Most of the AdSense publisher think that the background color of AdSense ads should be the same of their theme. As example, if their theme background is white and link color of the theme is blue, then most of the publishers use white and blue colors for ad background and link color respectively to their site. This is okay but sometimes we can run different. What will be happened if the background of Google ad is blue and link color is white for the same theme? Should audience be attracted to that? Do you have experience on it?
My advice is to choose the color of the AdSense ads not to maximize clicks or eCPM, but rather, to make your site look as professional as possible. Sometimes, a certain color scheme might actually improve your clicks, but will harm your site in the long-run because it will look more ad-cluttered and less appealing to potential return users or other webmasters who might link to your site. Pick the color scheme that makes your site look best. Then, within those constraints, you can experiment with different colors or placements to tweak your revenue a bit...but remember, you want your site to make a good first impression. And in the end, it doesn't matter if someone clicks the ads as much as it matters if they like your site and share it with others. Good luck!
Thank you. But I was thinking about some changes on google codes but found that google does not support any manipulations. I consider this line as important! I think this should be the main. Thanks dude!
