URL Structure
In one line
URL structure is the deliberate hierarchy and pattern of your URLs — from domain through directories to slug — designed so both users and search engines can read where a page sits in your site.
Going deeper
URL structure is the skeleton you set before you ever lay out a sitemap. The basics are a clear hierarchy — 'domain/category/subcategory/slug' — and the discipline to keep the pattern consistent.
Two early decisions tend to dominate: how deep the hierarchy goes, and whether categories show up in the path. Too deep and click depth dilutes authority; too flat and the taxonomy collapses once the site scales.
Restructuring after launch means site-wide redirects, which is why URL structure ends up entangled with information architecture and content strategy. Settling it early is by far the cheapest path.
