Sure, there's CPA offers on CJ too, but it's not their forte.
CJ and CPA networks are really apples and oranges.
Would it be reasonable to say that CJ is just not oriented toward paid (PPC) traffic? That most of those making money w CJ are getting their traffic organically?
Reading through the disallowed keyword lists, it almost seems like most CJ merchants don't even want PPC traffic or anyone bidding anything even remotely close to the keywords they're probably already bidding on in-house? (which would drive their own PPC costs up)
