Every few months I look through my server stats to see who is sending me traffic. The places that I don't see traffic from I stop submitting to.
It is important to understand that free site building is accumulated traffic in that the more you build and submit the more traffic you will get from each place since the listings are long lasting unlike TGP traffic in which a listing is usually very short lasting so if you have built and submitted ten sites you will receive ten times the traffic compared to if you had only built and submitted one site.
Wow that was along fucking sentence.
