By the way, I have used the following revenue generating pay per click services, and here is what I have found:
DomainSponsor - a bit difficult figuring out at first, but the revenue is great. I am averaging >$10/cpm. If you want to join, please do so via my site
http://www.dn4s.com so I can get a referral commision. If you sign up via my site, let me know and I will give you 200 DNF bucks.
Roar.com (Fabulous.com) - great service, with a zillion options, and you can probably make a lot of $ with the right domains. I average around $5/cpm.
TrafficZ - I got pathetic revenue. <$3/cpm, even though they have 2 programs, and one pays a "guaranteed" $3/cpm. Problem is that a lot of the traffic does not get counted, so the net cpm is more like $1.50
DomainSpa - I will give them a try when they get their online stats working. Until then, they are not ready for prime time.
Sedo - Not worth the time as the revenue was too low to calculate.
