This perl script ranks sites from the ones who send the most traffic to the least traffic. This script is so powerful that it will automatically analyze all incoming hits and determine where they are coming from without them signing up. The script will block sites loading your site in an image tag or iframe tag. It also allows you to track the productivity of your traffic and base your returns on it. You can also adjust your return ratio to each site. Also uses template features so that the script will work with your current site's design, and allow easy modifications.
