PPC, or Pay-Per-Click, is a digital advertising model where advertisers pay a fee each time one of their ads is clicked. It's a way of buying visits to your site, rather than attempting to “earn” those visits organically. The most common PPC advertising platforms are Google Ads and Bing Ads. PPC can include search engine advertising, where ads appear in search engine results, and display advertising on websites or social media. The cost per click can vary based on the platform and competitiveness of the keyword or target audience. PPC is a popular marketing strategy for driving targeted traffic to a website, and when executed correctly, it can offer an impressive return on investment.
