What to change
A device-specific decline may point to a narrower issue than the aggregate headline suggests. Ask the analyst to compare the same relevant pages and queries across device groups, then relate any concentrated change to recent releases. This provides a focused investigation brief for the supplier. It does not prove causation by itself, so retain working comparison pages and document whether the technical checks confirm or reject the suspected explanation.
A worked example
Illustrative example
Illustrative test: Compare the same service page's device segments rather than unrelated pages.
How to check the result
The investigation identifies a specific affected segment or rules out the device hypothesis.
A mistake to avoid
Different device audiences may have different intent and demand.
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.
