This proves a guarded reporting workflow. It does not prove that advertising or content created sales.

The claims test

Five questions before a number goes public.

Question	Why it matters
What changed?	Prevents different metrics being treated as equivalent.
On which system?	Keeps the result attached to the environment in which it was observed.
Across what dates?	Stops a momentary result becoming a permanent promise.
Measured how?	Makes the source and method inspectable.
What does it not prove?	Separates honest evidence from a sales story.

A useful first step is often establishing what can be trusted before deciding what should be improved.
