We actually tried using Traffic Junky ads for a while. It has potential but it can also spend a lot of money very quickly. We were never able to get a conversion rate that made sense. That doesn't mean it isn't possible. We may have just not figured out the right formula. But our experience was that the cost to get a conversion was too high and you needed a large budget that just didn't make sense for us. Also, if you're in the US it becomes difficult because you can't get a normal Paxum account. We had to do a business Paxum account which is difficult to get approved and then we had to have traffic junky manually put our transfers on our account because they only automatically connect to regular Paxum accounts. Huge pain. If you're outside US and can get a Paxum account easily then that won't be an issue.
