I've spent a bit of time with traffic exchanges. So it's always gratifying to find one that really works.
Not only have I generated some decent traffic to some wehsites, I've also earned a few dollars through their referral program.
And while I admit that it looks and acts much like many others, the performance of the visits and the cold hard cash convince me that their network is well managed.
If you're new to traffic exchanges, tread lightly. But never discount the value of free traffic.
