Acquisition efficiency diagnosis

Your CAC increased. Find why growth got more expensive.

Quick answer

Rising CAC is an efficiency problem. Paid media may cost more — or conversion fell, sales slowed, quality worsened, attribution broke, or spend shifted to costlier channels. Separate cost-per-click from conversion before you cut budget.

Did CPC rise, or only CAC?

Separate media cost from conversion.

02

Did signup or trial→paid fall?

Funnel breaks inflate CAC with flat ad prices.

03

Did channel mix change?

Expensive channels can hide behind a blended CAC.

Questions people ask

Why did my customer acquisition cost increase?

CAC usually rises because paid media got more expensive, conversion fell, sales efficiency dropped, customer quality worsened, attribution broke, or spend shifted to costlier channels. Separate cost-per-click from conversion rate before you cut budget.

Is rising CAC always an ads problem?

No. If conversion or trial→paid fell, CAC rises with the same ad spend. Fix the funnel before you assume the channel is broken.

How do I diagnose rising CAC?

Compare the same period for spend, clicks, signup rate, trial→paid, and sales cycle. Ask which moved first. Then check channel mix and attribution.
