Worked example

If a paid search campaign spends $2,400 and receives 1,200 clicks, CPC is $2.00. Segment branded, non-branded and retargeting clicks before judging efficiency.

CPC varies by auction, quality score, match type, audience and creative. Evaluate it with CTR, conversion rate, CPA and ROAS, because cheaper clicks can still be lower quality.

How it works

CPC helps acquisition teams understand auction cost before downstream conversion quality is considered.
