CPC bidding

Also written: Cost per click

Advertisers pay a fee each time someone clicks on their online ad.

In plain terms

Cost-per-click, or CPC, is a way to pay for online advertising. Instead of paying to show an ad, you only pay when someone actually clicks on it. This means you pay for potential interest in your product or service.

For example, if a company selling dog toys runs an ad for its new squeaky toy, it might use CPC bidding. They would set a maximum amount they are willing to pay for each click. If their ad gets 100 clicks, they pay for those 100 clicks, not for the thousands of times the ad was just seen.

The expert version

Cost-per-click (CPC) is an auction-based advertising pricing model where advertisers bid on keywords or placements. The advertiser pays the platform a predetermined amount each time a user clicks on their advertisement. The actual cost per click can vary based on the bid amount, the quality score of the ad and landing page, and competition from other advertisers.

Why it matters now

OpenAI is introducing CPC bidding for its ChatGPT ads, allowing businesses to pay for engagement rather than just impressions. This move signifies a shift towards more performance-based advertising models within the AI product space.
