Which one should I use. I have some books that I want to give away, maybe here or on youtube but that is not the question. CPA isn't available in some countries bot most people don't like filling out a survey, but PPC pays less but I think is available in every country. So what should I do, should I upload to media fire and cloat it with a PPC link or just do a PPD with a CPA, you know like sharecash or so. And which PPC is good, Adf,ly or ity.im. The last one looks goo because I heard that they pay $300 for every 1000 new members that you bring in, they wont take any of the new members money. That is awesome.
