I see there are several different affiliate programs people use here, and I wondering which to people consider the best? Also, do some cater to different niches better than others? how does one know which affiliate program is best for them?
It really depends on what you want to sell... in my experience it goes something like this: eBooks/instant downloads = ClickBank sex enhancement = OA Internet, LEC... (check my sig for more on these) big name brands = CJ But many other people have had success with other programs.
