What Is URL Slug?

A URL slug is the human-readable part of a URL that identifies a specific page, after the domain and folders. In example.com/blog/url-slug, the slug is "url-slug". Clean, descriptive slugs help users and search engines understand a page at a glance.

What makes an SEO-friendly slug

Keep slugs short, lowercase, and hyphen-separated; include the target keyword; and drop filler words where the slug still reads clearly. Avoid dates and unstable IDs you might need to change later, since changing a slug requires a redirect to preserve rankings.

Pro tip
Avoid putting dates or volatile categories in slugs. A stable, evergreen slug means you never have to redirect it when content is updated.

Frequently asked questions

What is an SEO slug?

An SEO slug is simply a URL slug written to be clear and keyword-relevant, so both people and search engines understand the page before opening it.

Can I change a URL slug after publishing?

Yes, but set up a 301 redirect from the old slug to the new one. Without a redirect you break existing links and lose the page's ranking signals.
