Here is a quick tip to increase your Adsense earnings. Add a Google Search box! One of the types of advertisements Google offers is called Adsense for Search.

To place a search box within your site:

• Log into your Adsense account and click on Adsense Setup
• Select Adsense for Search
• Select the options of how you want the search box to look and whether you want it to search just google, or your site, or both.
• Copy and paste the code into your site!

Here is a search box that I created. I prefer not to use the Google logo as to make it appear blended in the site better.

The best place to use this would be somewhere below the fold of the page. If users get down that far in the page and are ready to leave your site, why not have them give you a little revenue on the way out?
