*Core concept* · *Entity & Knowledge Graph*

## Definition

Brand authority is the perceived credibility and expertise of a brand in its domain — built through consistent content, citations, and third-party endorsements, and used as a trust signal by AI systems when selecting sources for citation.

## Why It Matters for AI Search

Brand authority is the AI search equivalent of domain authority in traditional SEO. It accumulates through consistent, high-quality content; authoritative external citations; and a well-maintained entity record. Brands with high authority are cited more frequently and more confidently by AI systems than less established competitors covering the same topics.
