I have a good number of people that buy traffic from me on a regular basis. I also have people that buy a small amount once and they don't wind up getting anymore.
I always try to give my customers advice on which types of my traffic would be best for their sites and also some suggestions on ways to improve the page that they are sending to.
It all comes down to money. If you make more money than you spent on the traffic, then you're ahead of the game. A profit, no matter what size is still positive cash flow.
Most of my repeat buyers seem to be having luck with FPAs, their own paysites, links lists, and a few other types of adult pages.
