Everyone knows that the way to a good site or referral link is traffic. Many people are now using traffic exchange programmes such as freemillionautosurf, however automated traffic surfers are almost completely pointless as the users aren't going to be looking at your site, at the very least a traffic exchange programme like Easyhits4u should be used, where the user has to answer questions after a time delay so at least they get a chance to look at your site.
