You're giving away too much with the free month thing, so here's a start. Put up
Adult Friend Finder geo-ads on the top of each of your tgps. The biggest mistake people make with AFF is pulling the ads too early because the free members aren't buying right away. Eventually, they will buy. Just collect as many free members as you can. Trust me, in a short time, you will easily pull 4 figures a month off 100k daily.
