How to interpret the result
A marketing metric depends on its attribution and cost definitions. A favourable ratio is not proof that advertising caused every sale or that future customers will behave the same way.
Compare campaigns with the same attribution window and outcome definition. Test a lower conversion rate or shorter retention period before extrapolating a promising result.
Common mistakes to avoid
- Do not double-count a customer or conversion reported by multiple channels.
- Revenue is not the same as profit available to fund acquisition.
- Small samples and changing cohorts can produce unstable comparisons.
Assumptions and sources
Privacy protection and automated scanning affect open/click data. Conversion attribution is not an incremental-sales test.
