*Core concept* · *E-E-A-T*

## Definition

Author authority is the credibility and expertise attributed to a content creator — used by search engines and AI systems as a signal of content trustworthiness. It is built through consistent byline presence, demonstrable credentials, cited expertise, and cross-platform recognition.

## Why It Matters for AI Search

Author authority is a component of E-E-A-T and contributes to content provenance signals. AI systems that can verify a content author's expertise — through Person schema, consistent bylines, external profile links, and citations in authoritative sources — have higher confidence in citing that author's content. Anonymous or unattributed content lacks these provenance signals and is weighted accordingly.
