I really want something that provides fairly targeted traffic, but doesn't cost an arm and a leg to drive. I know what's being promoted also counts so I would factor this in. Paid traffic is one of those things that's still very scary to me. I feel it's needed though if I'm going to be serious about IM.
I want to be clear when I say low risk, high reward I mean a form of traffic that will give you the most bang for your buck. This is even if you had an offer that didn't generate much money per sale. Any ideas of past experiences are appreciated.
