Stands for "Pay Per Click," and is used in online advertising. PPC advertisements generate revenue for Web publishers each time a visitor clicks on an ad. Banner ads, Flash ads, and textual ads can all be used to generate pay per click revenue for publishers. Many search engines also use the pay per click model, showing sponsored results along with other relevant results for searches. PPC is an attractive model for advertisers because they only have to pay for actual traffic generated by their ads.
