A practical sequence
- Verify that the intended action works and is counted once. A broken form can masquerade as weak demand.
- Review the promise before the click and the information after it. Check whether the visitor lands on the expected offer.
- Inspect meaningful segments such as device, source and intent. Avoid inventing a universal “normal” conversion rate.
- Use observed friction to form one hypothesis. If traffic is small, prioritize usability evidence before a statistical experiment.
Take this into the brief
Segment / Promise before click / Landing message / Observed friction / Tracking check / Hypothesis

A good brief names the suspected mechanism and the evidence that would disprove it.
