The discount that needs 75% more units.

Break-even volume on a promotion is almost always higher than the discount itself. At 30% off and a 70% margin, it is 75%.

A 4.0 ROAS that returns ninety cents.

Attribution asks who touched the sale. Incrementality asks who would not have bought otherwise. The difference can be most of the return.

LTV : CAC once assumed churn is replaced with observed churn

Customer EconomicsObservation 0042 min read

The ratio that reads 3 to 1, and isn't.
