PPC stands for pay-per-click, a model of internet marketing in which advertisers pay a fee each time one of their ads is clicked. Essentially, it’s a way of buying visits to your site, rather than attempting to “earn” those visits organically. Search engine advertising is one of the most popular forms of PPC.
In a PPC campaign, you pay Google however much you wish to have them list ads for your site at the top and right of the organic search listings. When someone clicks on your ad, you pay the current Cost Per Click (CPC) from your budget.
