Cams may be a harder conversion compared to paysites, not really sure as I quit running tgps after the 2003-2006 range so today mainly just promoting cams and almost all of my adult income comes from cams and the rest from mainstream. Will say that almost every member on the cam side I get spends at least $100-$400+ month. When taking in 30% but they continue to spend month after month doesn't matter if it takes more work to land them as you know they will continue spending once signed up based on statistical averages so initial acquisition cost can be higher as you know you will make it back up over the recurring months.
Get a white label, go revshare and analyze your traffic buys. Reduce spending to traffic sources not working and increase spending to sources that are working. You will waste money on sources not working but after some time analyzing and using tracker codes specific to each traffic source you will be able to find which sources are working and adjust your advertising to the most productive sources.
Variables that can differ peoples opinions on cams is the cam partner they choose along with the traffic source as all traffic is not created equal. You need premium country traffic US,CA,UK etc... and it needs to be targeted. Buying 100k popunders from all countries may not be as effective as buying 10k actual clicked traffic from a descriptive text link or matching cam thumb only from premium countries.
