I think it would be better if you just offer prizes that are free to you. So, anything besides PTC ads.
You can offer referrals, banner advertising, memberships etc. it's better to avoid costs if you can't afford them.
Most of the cases a member would be happy if you just offer him upgraded membership and/or bonus rented referrals and its actually profitable for you too. If a member receives good rented referrals, he would probably be wiling to pay to keep them. The same goes to the membership upgrades.. if a member realizes that it's really earning him much more than standard then he will probably be closer to invest on upgrading..
It's always wise not to put extra costs to yourself if you can't even afford your current ones..
You need to keep your site up and running and that's not gonna be easy, as it will not always cover the bills itself while it's still small. However if it grows enough it will not only cover the costs but it will also generate profits for you, but you need to make it through until then.
Quote:I advertised Amazbux and PTCBux at 500 views a piece. With $15 dollars worth of advertising, it seems like I would get more than one referral, who's not even active. Is there something I don't know?
Well, since the site is still new there are not many potential referrals here since the same people click the same link many times.
There are many factors also included.. maybe your members act like me when they notice a new PTC.. doing research on it before joining. And from my research they weren't worth the trouble.
Maybe it's just that they were not attracted by the design, or the rates, or anything. Maybe because they are new programs and they don't trust them.
We cannot judge when someone will join a site he visits or not.. it's practically impossible..
