Things you do to increase your AdSense revenue:

Filter ads you don’t like to be displayed on your page; you can do that, by using the set up section from your AdSense account.

Show your ads at visible section of your page; don’t expect readers to scroll the bar to find ads.  If your ads are visible or can be seen easily, reader will have access to it.

Put AdSense ads in between your texts on your page; the topic you are writing about on your page should be similar to your ads or your ads should be helpful/necessary to be clicked for more information.

Select pre-defined combinations of colors or create custom colors of your own. The background color of the ad should match the background color of your page. The text color of your ad should match the color of your page text. The URL links of the ad color should be similar to the other URL links on your page; usually links are colored blue, but you can use other color of your choice.

Add Google search box on your site and set the search box to get search results outside the page than inside your page; when people search using the search box on your page, you will make money.

Your page interface should be welcoming, clean, and simple to follow; visitors on your page should find information they are looking for. Your page navigation and speed should be reliable; putting images and flash might make your site navigation speed slow.

Use channels to track the performance of your pages; by tracking and changing different channels, you will know which channel gets you more traffic and you can keep the one which gets you more traffics/money.
