What does PPC stand for?

PPC stands for Pay-per-click, an advertising model where advertisers pay a fee each time one of their ads is clicked. This is a common model in search engine marketing (SEM), allowing businesses to bid for ad placement in a search engine's sponsored links. The advertiser only pays when a user actively engages with their ad by clicking on it, making it a cost-effective method for driving targeted traffic. "Price-per click" is incorrect because "Pay" more accurately describes the action of the advertiser. "Pay-per campaign" and "Price-per campaign" are incorrect because PPC specifically refers to the per-click payment model, not an entire campaign.
