Lately I've been thinking about scaling things up by using paid traffic. Anyways, yesterday I was checking Flippa and saw these auctions by a new seller with a model based on paid traffic. Basically, they were doing arbitrage by buying traffic on bulk and then sending it to their sites. On these sites, they'd put 3 banners per page and sell those ad spaces on Adbrite, charging CPM. ROI was unreal, like 1000%. Traffic came from all over the world and prices were about $85/100,000 visitors. Even though they claim these were all real people interested in these offers, I doubt this was the case, based on country of origin and time on page (I do believe they were real people though, not bots). Anyways, doesn't really matter this particular case, but here's my question: Has any of you been working on such a model (paid traffic to CPM in particular)? To the ones who have: What's your experience with such a model in the long run? Could you put me in contact with any decent traffic provider? Have you been working with Adbrite or selling at any other decent marketplace you could tell me about? Please, only answer if you've actually had some experience with this. Thanks and feel free to PM me if you feel it would be more appropriate. (BTW, just studying my options atm, so no promises).
