A reference standard for recording answer inclusion, citation presence, entity accuracy, prompt conditions and changes over time.

Minimum observation standard

FieldStatusReason
Exact promptRequiredAllows replication.
Surface/model labelRequiredProducts change; “AI” alone is insufficient.
Date/timeRequiredAnswers and citations are volatile.
Answer text/captureRequiredPrevents summary bias.
Citations/linksRequired when availableShows source selection.
Entity outcomeRequiredCorrect / competing / ambiguous / absent.
Source independenceRequiredSeparates owned, primary, editorial and syndicated evidence.
Personalisation contextRecommendedLocation/account settings can affect results.
Repeat countRecommendedOne response can be an outlier.

Reporting rule

Do not publish “ChatGPT says X” without the prompt, date and product context. Do not convert ordinary web-search positions into “AI citations.” The purpose of a standard is to make bad news publishable too: a competing entity or no citation is still valid data.
