Traffic exchanges are programs that allow you to view other people sites in exchange for visits to your own sites. The ratios change between programs but are usually in the ratio of view 2 and get one view of your site. The good thing is that Traffic exchanges are free and allow you to build a net profile. If you upgrade then you will be able to get a 1:1 ratio which gets your pages seen more often.
I have found that StartXchange, EasyHits4U, WebBizInsider and Lords-of-Traffic have been the top performers.
