*Methodology* · *Technical SEO*

## Definition

Site architecture is how a website's pages are organized and connected, the hierarchy, the navigation, and the internal links that define how content is reached. It shapes how a crawler moves through a site and how it understands the relationships between pages.

## Why It Matters for AI Search

A crawler discovers and weighs pages by following a site's structure, so architecture decides what gets found and how important it looks. A shallow, well-linked structure lets retrieval systems reach every page and read the relationships between them. A deep or tangled one buries content where it is crawled rarely. Site architecture is the layer that makes content reachable in the first place, before any of it can be indexed or cited.
