URL structure is the format and organization of a web page’s URL — including domain, subdirectory, and slug components. Clear, descriptive URL structure signals content hierarchy and topic to both search engines and AI crawlers, and contributes to crawlability and link equity distribution.Why It Matters for AI Search
Descriptive URLs that include topical keywords and reflect content hierarchy give AI crawlers additional topic signals before they even parse the page content. A URL like/glossary/entity-optimization communicates topical context immediately; a URL like /p?id=4721 provides no context at all. For brands building large content sets — like a glossary — a consistent, descriptive URL structure is both a user experience and AI crawlability asset.
