Google AdSense is an important stream of income for any website owner, and the income from AdSense can be maximized without too much effort or headache by using a quality tracking script.

The best AdSense tracking script I've found can track all of your ads -- on multiple domains -- from just one installation on your server and a one-time fee for the script (no more inflated monthly fees).  Since you install it on your own server, you're not at the mercy of a monthly service fee or the server reliability of the script owner.
