TrafficSwarm is 100% FREE. It always has been, and it always will be. You do not have to buy anything, "upgrade" anything, subscribe to anything, or spend any money if you don't want to. Great results can be had absolutely free. For those that wish to do so, several credit packages are available for purchase. You can also upgrade to a "Pro" account for a small monthly fee if you want, with many great benefits. We generate most of our revenue from these latter two sources.
