## Definition

Information architecture is the structural organization of content on a website — including navigation hierarchy, URL structure, content taxonomy, and internal linking patterns — which affects both user experience and machine crawlability. Good information architecture makes the relationships between content explicit and navigable for both humans and AI crawlers.

## Why It Matters for AI Search

Information architecture shapes AI crawler understanding of a site's [content structure](https://www.platelunchcollective.com/services/citation-ready-content). A site with clear, logical hierarchy — where related content is grouped, internally linked, and taxonomically organized — enables AI crawlers to understand topical relationships across a site rather than treating each page as an isolated document. Brands building topical authority in a domain should structure their information architecture around topic clusters, with clear hub-and-spoke relationships between pillar content and supporting detail pages.
