I would never really use PPV traffic seriously. It costs like $8 for 10,000 hits, on google cost per click ads this would cost you $5,000 - there is a reason it is cheaper...

... because it is largely junk traffic. It is from people who are browsing your site to get credits to send people to their sites in return, or people who get "credits" for browsing your site to claim gifts etc - they are not really interested in your niche, they didn't search for it, they are just not buyers.

I get 10s of 1000 of hits from PPV each week, and it rarely EVER converts. I don't even want it, every week I write to Clickbank with the IDs of affiliates who send this traffic and get them blocked from sending it to me.

I know you want the traffic for slightly different purposes, but still, to me this traffic is reral junk and not worth it.
