## Definition

Internal linking is the practice of linking between pages within the same website — connecting related content, distributing page authority, and signaling topical relationships to search engines and AI crawlers.

## Why It Matters for AI Search

Internal linking is how AI crawlers understand the architecture of a site's knowledge. A well-linked site communicates which pages are most important, how topics relate to each other, and where the authoritative version of a concept lives. For a glossary-driven content strategy, internal linking is the mechanism that turns individual entries into a connected [knowledge graph](https://www.platelunchcollective.com/services/entity-seo) — each term linking to related terms, related blog posts, and relevant service pages, building the topical web that AI systems use to assess authority.
