CPC, which stands for Cost Per Click, is a core metric in digital advertising. It shows how much an advertiser pays for each ad click, making it a critical tool for tracking and managing ad costs. CPC is influenced by the advertiser’s bidding strategy, the relevance of keywords, and the quality of the ad itself. Optimizing CPC can lead to more cost-efficient campaigns. Advertisers can lower CPC by enhancing their keyword targeting, improving ad relevance, and using strategic bidding methods to ensure they get the most value from their ads.
