Google's AdSense program allows a wide range of content-based Web sites to run contextual advertising and earn revenue without having to take the time to sell and manage ad inventory. For many sites, AdSense has provided the first chance to make a profit off of a labor of love.

Knight, like many Internet publishers, was quick to jump on the AdSense bandwagon and start running the ads on his site. A few months after signing up for the program, he took the time to add some tracking scripts that would allow him to more closely track the impact of the ads on his site.

Other issues include the impact on conversion rates when ads are enticing users to leave your site and the inability to have AdSense ads launch new windows are points that site owners need to consider before signing up for the program.
