Folder depth in URLs: Crawl Audit check 45

Short answer: check 45 warns when the URL path has more than four folders, as in /a/b/c/d/e. Google doesn't set a depth limit, and says it generally doesn't read URL folders to understand your site. What does matter is click depth: how many clicks it takes to reach a page from your homepage. A deep URL is fine. A page buried six clicks deep isn't.

What Crawl Audit checks

• Pass: four or fewer path segments.
• Warning: five or more.

Every explainer on this site sits exactly at the limit: /tools/crawl-audit/checks/1-gptbot-permission-robots-txt is four segments deep.

What Google says

• "Google generally doesn't look at the structure of URLs to work out the structure of a site."
• Instead: "Google can use information such as the number of links it needs to follow to reach a page and the number of links to a page to infer the relative importance of a page".
• Folders still have a use. The SEO Starter Guide says "using directories (or folders) to group similar topics can help Google learn how often the URLs in individual directories change."

So the four-folder line is Crawl Audit's rule of thumb. Treat a warning as a prompt to check click depth, not as a reason to rewrite URLs.

What to check instead

• Click depth: can you reach your important pages within three or four clicks of the homepage, through normal links?
• Hubs: a section page that links to everything inside it, like this site's index of all Crawl Audit checks.
• Links from pages Google already knows: the SEO Starter Guide says "Google primarily finds pages through links from other pages it already crawled", so link new pages from established ones.

On your platform

• WordPress: the Post name permalink keeps posts one level deep. Category-in-URL structures add depth.
• Shopify, Wix and Squarespace: the platform sets the folder structure (such as /products/ or /blog/). Focus on your menus and section pages instead.
• Next.js: nested route folders become URL depth, so don't nest routes just to organise your code.
