Cpc (Cost Per Click)

An essential digital advertising metric and pricing model that reflects the cost advertisers pay per user click on their online advertisements.

Definition

Cost Per Click (CPC) is a performance-based pricing model in online advertising where an advertiser is charged each time a user clicks on their ad, rather than paying for ad impressions. It quantifies the average cost incurred for each click by dividing the total ad spend by the number of clicks received. CPC is widely used in pay-per-click (PPC) campaigns across search engines and social media platforms because it aligns cost directly with user engagement. This metric helps businesses assess and optimize their advertising efficiency and budget allocation. Understanding CPC also involves considering factors like bid competition, ad quality, and relevance that influence the final cost per click.
