CPC shows the average price paid for each click on an ad, making it a foundational efficiency benchmark for comparing campaigns, platforms, or keyword targets against each other.
Worked example
For $500 in ad spend generating 250 clicks:
CPC = 500 / 250 = 2.0 per click
CPC alone says nothing about whether those clicks actually convert into customers - always pair CPC with conversion rate and CPA (cost per acquisition) to get the full picture of campaign efficiency, since a low CPC with a poor conversion rate can still produce an expensive campaign overall.
