How exactly does pay per click work? Does anyone actually make much money with this? I signed up for a site that said it was pay per click , but I didn't make much at all.
I think you need to be a little more specific with yoru question. PPC is when an advertiser places an advertisement and pays each time somebody clicks on that advertisement. Plenty of people make a lot of money from it, but I am not sure exactly what you are talking about.
