Over the course of my Internet marketing career, a significant portion of my revenue has come from affiliate networks. With most networks, you can sign-up for free, earn money from several different affiliate programs at once, and get a single consolidated paycheck from one company.

You can also choose which programs you want to participate in, and avoid the trouble of signing-up seperately to each one. In most cases, however, your website will need to be approved by the manager of each program individually. As long as your site is well designed and has good content, it should be accepted into most of the programs that you apply for.

Different programs, of course, will pay you for different things. Some will only give you commissions when you sell one of their products on your website, while others will pay you when one of your visitors fills out a form, or simply clicks on a link. Affiliate networks allow you to experiment with a variety of programs, and decide which ones are best for your site.

Two of my favorite affiliate networks are Commission Junction (http://www.cj.com), and ClickXChange(http://www.clickxchange.com). Each of them has hundreds of high quality programs to join, and explore. Give it a try - you may be pleasantly surprised by the result...
