What to change
Trace the complete fictional journey before changing exclusions. Determine whether the domain is an intermediary in the visitor's task or a genuine source of new visitors, then review the relevant platform configuration. A referral setting and cross-domain continuity address different questions, so ask the measurement owner to explain both where applicable. Keep the interpretation tied to the observed setup rather than promising that one exclusion will reconstruct every earlier source.
A worked example
Illustrative example
Illustrative test: The analyst can explain the recorded source at each boundary of the test journey.
How to check the result
The chosen setting matches the provider's actual role and its reporting limits are documented.
A mistake to avoid
Changing a referral exclusion does not repair every cross-domain problem.
Your action checklist
Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.
