I am planning to promote friendfinder.com, but some of such sites have rules such that 10% of leads shd convert to sales.. is it like that? If anyone worked with them plz let me know
yes, they have this kind of rules, it is stated in their TOS and on your page with the basic links. It would be better to simply use PPS or Revshare programs I think. If you need dating campaigns that pay on free signup you should try some CPA networks, they have plenty like singlesnet or mate1.
