Pay Per Click (PPC) is a advertising model. The compensation that advertisers pay the publishers is based on click-throughs. This payment model is controversial, because a increase of the scope of a adversiting campaign does not relate to the sales of a product. Search engines do often use Pay Per Click models. EPC (“Earnings per 100 clicks”) is the average provision the advertiser pays to the affiliate. Pay Per Action is a further advertising model.
