Slug vs. URL — What’s the Difference?

What‘s the difference between slugs and URLs?

This is a slug:


A slug is just a part of a URL

This is a URL:

This URL is constructed by:

  • a protocol: https://
  • a domain:
  • a slug/path: what-is-a-value-javascript

The URL refers to the entire thing.

The slug is the part of a URL that explains what the page (path) you’re going to is about in human-friendly keywords. I wrote slug/path above because both terms are used. Slug is especially used in the SEO scene.

To reinforce and sum it up:

  • a slug is a descriptive path in a URL
  • a URL refers to the entire thing (protocol, domain, slug/path)

Your slug is an important part of SEO (Search Engine Optimization) so it’s worth learning how to create user-friendly slugs on your website.
