A couple months back, a free PPC affiliate tracking service called Tracking202 was released in a public Beta.
The same guys are back with a free, self-hosted PPC affiliate tracking software called Prosper202.
“It provides the same advanced PPC tracking that was publicly available on Tracking202.com. The software also comes with Export202, which is an application that allows you to upload PPC campaigns from your networks, and then export them to Yahoo, MSN and Google Adwords in seconds,” commented Steven Truong, Vice President, Media for Tracking202.
