Free signups are a scam. Actually, a visitor signs up for a free trial for one site, but joins two others he is not aware of. Of course those programs will scam affiliates as much as they scam their customers. Chances are you will be shaved out of 3 of 4 members you refer.
Yes I would recommend you go with a percentage option as win win for both sides there and much more money to be made long term imho, but your call of course
Programs that offer both options cheat on both. You get less on percentage, because you won't ever see a cent of their upsale or xsale earnngs. Best to use programs offering revshare, only, imho. Rebills rule![]()
