Pay Per Click (PPC) Advertising is a type of online advertising in which advertisers (i.e. you) pay for visitors on a Cost Per Click (CPC) basis. That is, advertisers only pay when a Web searcher actually clicks on a link and visits their Web site. PPC advertising is different than "traditional" online advertising, where advertisers pay according to how many times their ad is displayed. With Pay Per Click Adverting, an ad can be displayed many times, but the advertiser pays nothing unless a Web searcher actually clicks on the ad.
