This is a Traffic Exchange program that works with points. It's really simple, surfing websites will earn you 1 to 5 points, every time your website is displayed it will cost you 1 or 3 points, depending on the text that goes with the link people click on.

There is a free membership and a Pro (paid) membership of $30 a month. I signed up for the free membership. 

In addition there are all sorts of ways you can earn traffic. There is a start page that you can set in your browser (earns you 1 point per startup), you can surf links, you can refer others (100 points per referral), play games for points or play the lottery if you feel lucky.

I've had some succes using TrafficExhange so I can recommend it to you as well.
