Cost-Per-Click (CPC) measures the cost of each ad-click in Pay-Per-Click (PPC) campaigns. It is calculated by dividing the total advertising cost by the total number of clicks. For example, if a company paid $150 for a campaign that received 42 clicks, the CPC would be $3.57 (150/42 = 3.571). CPC is improved by fine-tuning campaigns, ad groups, and ads by optimizing keywords, copy, landing pages, forms, buttons, headlines, etc.
