URL Structure

URL structure is the way a site organizes and formats the addresses of its pages, from the folder hierarchy down to the words in the slug.

A clear structure helps both people and search engines understand where a page sits and what it covers. Google has said it uses words in the URL as a minor signal and that simple, descriptive URLs are easier for users to read and share. The bigger gains are indirect: a logical hierarchy supports sensible internal linking, makes the site easier to crawl, and produces cleaner breadcrumb trails.

Good practice favors short, readable, lowercase URLs that use hyphens to separate words, avoid unnecessary parameters and session IDs, and reflect the site's information architecture. A path like /blog/technical-seo/url-structure/ communicates context at a glance, while /p?id=4821&ref=x does not. Consistency matters too: pick one convention for trailing slashes, casing, and the use of subfolders versus subdomains, then apply it everywhere to avoid duplicate versions of the same page.

Two cautions. First, do not over-optimize by stuffing keywords into URLs; descriptive is the goal, not repetitive. Second, changing URLs on an established site is disruptive, because every change needs a 301 redirect from the old address to preserve links and rankings. URL structure is best decided early and changed only with care.
