I'm curious about this too. I feel like it's mostly a matter of finding the right traffic sources. I had my adwords rejected when I tried linking direct to my affiliate page, so I made a splash page with a big picture that says "click here" which directs people to my affiliate page.
Waiting on the review of that one. Adword makes me uncomfortable though. I've just heard too many stories about people getting banned and not being able to retrieve the money they put into their account and what not. Which to me, sounds just criminal.
They seem to get quality traffic, but ya know...I'm definitely looking for other sources.
So far I tried 7search with lacklustre results. I'd give it a 3 out of 10 on my satisfaction scale.
Will let you know if I find a better one.
Anyone have any luck with this yet?
I saw facebook. That sounds like an option. I like what they do with events/posts I've promoted in the past.
