Actual PTR/PTC Earnings

In all honesty, you won't earn a great deal of money in PTR/PTC. I've seen people posting in forums that they're earning over $100 per month just from PTR. Well, I'm not saying that's impossible. It's possible, IF you have a decent downline. Different PTR sites have referral earnings ranging from 5% up to 30%. Some may offer higher or even multi-level referral earnings, but then, there comes the question of sustainability.

Below, I have listed a few PTRs to which I'm signed up, and the typical daily earnings (excluding referral earnings) if you're in a search country. The earnings stated also exclude PTP earnings, since that depends on how well you advertise the PTP pages. Those who aren't in a search country, will find their earnings significantly lower.

Average click value = 0.25c
Avant-Cash = 5c ($2 Payout)
Apple-Clicks = 10c ($3 Payout)
BeeHiveMail = 10-15c ($1 Payout)
Klikkini = 15c (euro) (€2 Payout)
MoraTraffic = 3c (No Min. Payout)
PolarPTR = 5-10c ($1 Payout)
Random-PTCs = 7-10c ($1 Payout)
SoRedTheRose = 5-10c ($2 Payout)

Average click value = 0.5c
AdPaid = 10c ($5 Payout)
Classical-Mail = 20-25c ($0.50 Payout)
YeahCash = 3-4c ($3 Payout)
YourPTR = 50c or more, but that's a lot of clicking! ($35 Payout)

Average click value = 0.75c
3QuaterMails = 10-15c ($2 Payout)

As you can see, most of these sites allow you to reach the stated minimum payout within 1 month of activity. Potentially, you could be earning $40-$50 per month from just these programs, without referrals. But, in all honesty, to earn that, you'll be clicking over 500 emails a day! In reality, you'll be lucky to be able to make $25 per month.

Then, why continue with PTR? For me, it's more of a learning experience. PTRs offer relatively cheap advertising, and allows advertisers to promote their website/products.
For PTR members, PTR offers a small incentive for their time. For some, PTRs are just a stepping stone before going into (riskier) online investments (such as Autosurfs and HYIPs).
