If you are a webmaster, chances are you know about Google AdSense. The AdSense program allows website publishers to display relevant advertisements on their website to earn revenue. The website publisher will earn a percentage of the advertising revenue when their website visitor clicks on the advertisement.

Today, there are many webmasters enjoying hundreds of dollars a day or more with the AdSense program and here are 5 great tips to improve your earnings.

1. Use an ad format that is working well for many other webmasters. According to Google, the 336 x 280 rectangle, the 300 x 250 rectangle and the 160 x 600 sky scraper result in the highest number of click-throughs. Experiment with different ad formats and track the results for your website to maximize your revenue.

2. Create a custom palette for your ads. Choose a color that goes well with the background of your site. If your site has a white background, try to use white as the color of your ad border and background. The idea here is to make the AdSense ads appear as though they are part of the web pages.

3. Placing your ads in the right location can make a big difference in your earnings. For example, when it comes to articles, your ads can be effective by being placed right below the article. This allows the reader to have something to do after reading the article and that is clicking on your ads. If you visit Google's website, they have published a "heat map" to demonstrate AdSense positioning.

4. Use multiple ad units. According to Google's Terms of Service, you are allowed to post up to three ad units per page.

5. Add a new page of content to your website every day. The more content your website has will result in more visitors finding and returning to your website. If you place Google AdSense on every page of your website, this will improve your earnings.

These are 5 tips that have worked well for many webmasters who generate revenue using Google AdSense. Keep in mind that the ads are displayed according to your page's content. Build great content for your visitors and watch your AdSense revenue grow!
