Person Schema
Person schema is structured data describing an individual — their name, role, and authoritative profiles — that helps AI systems recognize an author or expert as a known entity.
Person schema makes an author machine-recognizable. It's the schema.org type for an individual, describing their name, job title, and — via sameAs links — their authoritative profiles, so engines can connect a byline to a real, identifiable entity.
For AEO it supports the authority and credibility pillars by helping engines tie your content to a known expert and link their work across the web. It's low-cost entity infrastructure, not a magic authority switch: the schema clarifies who wrote something, but the expertise itself has to be real and corroborated elsewhere. Used well, it helps an engine consolidate an author's reputation into one trusted identity.
Example. An author bio with Person schema and sameAs links to their LinkedIn, university page, and published work helps an engine confirm that the "Dr. Jane Smith" on your site is the same recognized expert cited elsewhere — strengthening trust in the byline.
