In a previous article I talked about the 3 Google Adsense Success Factors. But if you already have a website, you can increase your adsense income almost immediately improving your Clickthrough Ratio (Adsense CTR) The 2 other factors (Website traffic and Income per click) can also be improved but they will take more time.

First you need to study carefully the optimization tips provided by Google at:

One of the things that set Adsense apart from other banner ad programs is your ability to customize the code to fit the look of your site, and the wide variety of unit sizes available. As a website publisher you can control the following components.

1. Text Color
2. Background Color
3. Border Color
4. Ad Format
5. Ad Placement
6. Number Of Appearing Ads

You can control these components, but you can’t control the copy of the shown ads because advertisers write the ads which are then shown on your site. Therefore, in this way, there is a limit on what kind of optimization you can perform. You can’t make advertisers write better ads afterall, luckily though Google is constantly analyzing advertisements and ones that do not get clicked on end up filtered out or shown less often.

In future articles I will analyze in detail how to optimize each of these components.
