PPC stands for pay-per-click, a model of internet marketing in which advertisers pay a fee each time one of their ads gets clicked by someone. It lets marketers place ads on an ad platform and pay the host of that platform every time their ad is clicked.
It’s a method of buying visits to your site, rather than attempting to “earn” them organically. The goal of such a tool is to lead the person viewing it to click through to the advertiser’s website, where that visitor can complete a valuable action, such as purchasing of a product.
