Set the approval boundary up front
Identify the person who can approve product facts, the person who can publish the page and the person who can verify it in production. Record regional restrictions, review requirements and the customer claims that require additional evidence.
Make the pilot small enough to release
Choose buying questions tied to one product family. Inspect a small set of owned pages and cited sources, then separate changes the pilot team controls from changes that depend on partners. Schedule the second measurement around an actual release.
Use an expansion decision the team can defend
Compare the same prompts after the release. Review factual accuracy, any change in mentions or citations and the effort needed for approvals. Expand to another market when the business owner can repeat the process with a local fact sheet and publishing path.
