Why CPC matters
CPC alone is meaningless, a cheap click that never converts costs more than an expensive click that does. Evaluate CPC alongside conversion rate, CVR, and resulting CPA.

Common mistakes with CPC
- 1
Looking at single-channel ROAS in isolation instead of blended MER. Last-click attribution overweights bottom-funnel channels and starves top-of-funnel.
- 2
Setting a uniform target across products with different margins. A 2× ROAS is profitable on 80% margin and unprofitable on 20%.
- 3
Optimizing CAC without measuring LTV. Cheap customers with bad retention destroy unit economics.
How to improve CPC
Run incrementality tests every quarter to validate which channels actually drive new revenue vs steal credit.
Build a unit economics dashboard separating CAC, LTV, contribution margin, and payback by channel and cohort.
Establish a contribution margin floor for each channel, pause spend when margin drops below threshold for 14 days.
