In AEO, provenance is what separates a reusable fact from an unsupported claim. When an AI system says that a company has a certification, founder, office, customer, integration or funding round, the strongest answer is one that can point back to a source with authority over that fact.
What provenance should capture
- The publisher or institution behind the source.
- The document, URL, filing, profile or dataset where the fact appears.
- The publication date, update date and validity period where relevant.
- The relationship between the source and the claim: primary authority, secondary coverage or weak repetition.
- The correction path if the fact is wrong or outdated.
W3C PROV describes provenance as information about the entities, activities and people involved in producing a piece of data, useful for assessing quality, reliability or trustworthiness. That framing maps directly to AEO because answer engines need trustworthy context, not only fluent text.
