That question is probably a bit too close to the terms of service constraints. I would expect a moderator to take the domain off the post as it constitutes an advert.
But... The market leaders in PPC (I think it is fair to say) are Google and Overture. The one you mentioned (on their own site) claims to be ranked 179. There are a number of websites that give opinions and ratings of all pay per click suppliers, but usually their strength depends on the power of their partners. Ask yourself if their results appear on third party sites of "substance"?
Of course, if you want cheap traffic then the smaller PPCs are great. But then ask yourself "Am I the only person going to ever click on my result?" and if not, where are the real users coming from.
Having a tracking system that allows you to track sales back to original inbound links makes these sorts of questions much easier to answer.
Lol they replied back to me and said i can only use my 2000 credits for advertising, but then i go to log in they took 1500 credit or more out that i earn because 94 referrals more than that and dropped to 500 then i go to log in to my account ans says i'm not found. so I got my answer. Thanks. I asked what's up with that and now no response
