What is CPC (Cost Per Click)? Examples of CPC

In digital analytics, CPC (Cost Per Click) is a metric that measures the average cost an advertiser pays for each click on an ad link. It quantifies the expense incurred when a user clicks on an ad, providing insight into campaign efficiency and budget utilization. CPC is calculated by dividing the total cost of clicks by the number of clicks received. This metric is essential for evaluating the performance of pay-per-click (PPC) campaigns across platforms like Google Ads and social media channels. Understanding CPC allows marketers to adjust bidding strategies, improve ROI, and optimize ad spend. In analytics platforms like Google Analytics 4 (GA4) and PlainSignal, CPC data helps tie advertising costs to on-site behaviors and conversions, enabling more informed decision-making.
