Cost Per Click (CPC) is a digital 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 quality of the ad. Advertisers set a maximum bid for how much they are willing to pay per click. The actual CPC may be lower than the maximum bid, depending on the ad's performance and the bidding strategy. Effective management of CPC can lead to better returns on investment for advertisers.
