PPC, or pay-per-click advertising, is a digital advertising model where advertisers pay a fee each time their ad is clicked. Rather than paying for broad exposure measured in impressions or airtime, PPC advertisers pay specifically for traffic, each click brings a visitor to the website or landing page, and the cost reflects the competitive value of that audience at that moment. The most common form of PPC is search advertising through Google Ads, where ads appear above organic results when users search for relevant keywords.

PPC operates through an auction. Advertisers bid on the keywords they want their ads to appear for, and the combination of bid amount and ad quality determines placement. Higher bids and higher-quality ads earn better positions at lower effective costs, which is why optimizing ad relevance and landing page quality is as important as the bid amount itself.

For businesses, PPC is valuable because it can generate traffic and results quickly and because performance is fully trackable. Unlike organic search, which takes months to build visibility, a well-structured PPC campaign can produce leads within days of launch. The ability to set daily budgets, pause campaigns, and track every result at every step makes PPC one of the most controllable and measurable forms of advertising available.
