Cost Per Click (CPC) in advertising is a metric that determines how much you pay for each click on your ads. It is a crucial element in digital marketing, especially in pay-per-click (PPC) campaigns. The formula for calculating CPC involves dividing the total cost of clicks by the number of clicks received, helping marketers assess campaign efficiency and ROI. Advertisers can optimize their CPC by improving quality scores, refining keyword selection, and creating more compelling ad copy that resonates with their target audience.
