CPC is an abbreviation for Cost Per Click. In digital advertising, it is both a key metric and a billing model that determines the exact amount an advertiser pays for a single click on their advertisement by a user.
It is the core metric for campaigns operating under the PPC (Pay Per Click) model, widely used in platforms such as Google Ads and Meta Ads (Facebook Ads).
What does this mean in practice?
- Billing Model: You pay only when a user actually clicks on your ad and is redirected to your website, rather than just for the ad being displayed (as in the CPM – Cost Per Mille model).
- Calculating CPC: Average CPC is calculated by dividing the total cost of your advertising campaign by the total number of clicks it generated:
CPC = Total Cost of Campaign Total Number of Clicks
Maximum vs. Actual CPC:
- Maximum CPC (Max CPC): The highest amount an advertiser is willing to pay for a single click.
- Actual CPC: The final amount an advertiser is actually charged. It is usually the minimum amount required to outrank a competing ad and does not exceed the Max CPC.
CPC is a fundamental indicator because it allows advertisers to directly monitor the cost of acquiring website traffic and evaluate the overall efficiency of their campaigns.
