Define pay click advertising?

In the pay-per-click (PPC) model of digital advertising, a company reimburses an ad publisher for each time a user clicks on one of its commercials. Although the term "PPC" is frequently used used to refer to search engine advertising platforms like Google AdWords, several advertisers use the business model.

A publisher (usually a search engine, website owner, or network of websites) receives payment from an advertiser when an ad is clicked using the pay-per-click (PPC) internet advertising model.
