i'll give you a hit.you posted in the Pay Per Click Advertising forum. you get paid for clicks on an ad.
If you join a PPC program, you'll get paid every time someone visits the website through your affiliate link. You can gain very little from it unless your site has thousands of visitors everyday. Usually, the one person winning from a PPC program is he who runs it himself. That is, if you have a website you want to promote, you can start your own PPC program and get people to promote your site, and you'll have to pay them for every click/visitor. You can start it easily with clickbank.
PPC - Pay Per Click it means that if we advertise some where we pay only for clicks and not for impressions n stuff
