In an effort to get more eyeballs to my site, I joined a few traffic exchanges. Over time, some proved to be worth the effort and others were not so effective. One of the best ones so far has been ClickPirate. I've gotten a steady stream from them. I also like Traffic Swarm, the traffic is more targeted since users get to pick which site they want to view. I dropped Traffic Soldiers and Top Surfer because neither one of them sent many hits my way. And Top Surfer bombards your inbox with emails from its members.
Any recommendations for good traffic exchanges?
