What Exactly is CPC?

Cost Per Click (CPC) is a digital advertising pricing model where advertisers pay a fee each time their ad is clicked. Unlike traditional advertising where you pay for ad space regardless of performance, CPC ensures you only pay for actual engagement.

CPC = Total Ad Spend ÷ Number of Clicks

Key CPC Concepts

Max CPC: The highest amount you're willing to pay per click
Actual CPC: What you actually pay (often less than max CPC)
Average CPC: Total spend divided by total clicks over time
Quality Score: Affects your CPC in search ads (higher quality = lower CPC)
