COST PER CLICK (CPC)

Back to Glossary

Definition

An online advertising pricing model where advertisers pay each time a user clicks an ad.


Summary

Cost Per Click (CPC) is a fundamental digital advertising payment method where advertisers only pay when someone actually clicks on their ad, rather than just viewing it. Think of it like paying for actual engagement rather than just exposure - similar to paying a salesperson only when they successfully get a customer to enter your store. The advertiser sets a maximum amount they're willing to pay per click (called a 'bid'), and the actual CPC is determined through an auction system where ads compete for placement. This model is popular because it's performance-based and allows advertisers to directly measure the cost of driving traffic to their website.

Usage Context

Essential for understanding digital advertising costs, budgeting for online marketing campaigns, comparing advertising effectiveness across platforms, and making data-driven decisions about ad spend allocation.

Common Confusions

  • Confusing CPC with CPM - thinking you pay for impressions instead of clicks
  • Believing that higher CPC bids always guarantee better ad placement
  • Not understanding that actual CPC paid is often lower than maximum bid
  • Thinking CPC is the same across all platforms and industries
  • Confusing CPC with the total campaign cost or cost per conversion
