I’d suggest dating affiliate products. “How to meet girls/guys” type stuff. Have a look on Clickbank. Also, check out Real Social Dynamics - they have some great products, some of which are cheap and some are expensive, giving you a wide range of commission possibilities.
Also, assuming your site qualifies, Adsense is likely to make you a lot more than any other advertising network.
Ya know, I was hesitant to use AdultFriendFinder because I just see them everywhere! I figured people would have seen their ads everywhere too and would be less likely to click them… Boy was I wrong. lol
Thanks for the advice everyone! I’ve been running the AFF ads for part of yesterday and all of today and already I’ve made $58+!!
