its a site for traffic generation to your website or blog and i am trying them for the first time..well..till now i can say as per my experience with them..at least they do send visitors to my site..but may be its because of my newer account there as they say traffic will be doubled if i upgrade..i know i am not going to upgrade there just for the traffic but are they worth continuing for long..till now i can say i found them better than traffic swarm as all traffic sent was from US and UK even when i haven't chosen it!
