Cost-Per-Click (CPC) is an online advertising model where advertisers pay a fee each time a user clicks on their ad. This model is commonly used in platforms like Google Ads and Facebook Ads, allowing businesses to drive traffic to their websites. The cost can vary based on factors such as competition, keywords, and the ad's quality. Advertisers set a maximum bid for how much they are willing to pay per click. If their bid is competitive, their ad may appear in search results or on social media feeds. Effective management of CPC campaigns can lead to better visibility and increased website visits.
