1) Dating - Revshare - People with the intention to find a partner for life will spend quite a time looking around, writing, building virtual relations.
2) Adult Dating - PPS - The guys are up for a quick fuck and will switch to the next site if they aren't successful and get replies from fake promo profiles only.
3) VOD Porn - Revshare - It's built for revshare, casual porn users who don't want to go out and rent a DVD, very loyal customers.
4) Webcam Girls - Revshare - Using PPS for some sites, but revshare most of the time since I wouldn't want to miss those guys spending hundreds or even thousands a month. Whales are rare, but well make up for those only spending money once.
5) Typical hardcore paysite - Revshare and PPS - Totally depends on the sponsor and my experience with their retention. Definitely PPS if the members area sucks or rebills magically disappear to a large extend compared with other similar sites.
6) Single Girl Paysite - Revshare - Solo girl site members are often loyal fans looking for some kind of virtual girlfriend, they stay for a long time. Again, if it's just content of the girl, no extras, no webcam shows, no member interaction, I use PPS.
7) Pharmacutecals - Revshare, but not promoting them much
8) Typical porn video site - Revshare - Same as for hardcore paysite
I never hit up anyone beforehand, since I'm always busy and often quite a time passes till I start sending traffic after signup...so, I'm waiting till I see good results and have a better position to ask for more
