What Is a URL Slug? (And Why It Matters for SEO)

When you visit a website, you see a string of text in the address bar — something like:

https://www.example.com/blog/what-is-a-url-slug

In this example, the slug is the part at the end:
what-is-a-url-slug.

It may look simple, but this short bit of text plays an important role in SEO, readability, and user experience.

🧭 What Is a URL Slug?

A URL slug is the part of a web address that comes after the domain name and identifies a specific page.

For example:

• example.com/about → slug = about
• example.com/blog/best-seo-tools → slug = best-seo-tools

In short, the slug tells users and search engines what a page is about.

Search engines use slugs to understand your page topic. A clean, keyword-rich slug helps your content rank higher in search results.

2. User Experience

Readable slugs look professional and make it easy for users to guess what’s on a page before they click.

3. Brand Consistency

Consistent slugs reinforce your brand’s professionalism and improve navigation across your site.

2. Convert to lowercase → what is a url slug
3. Replace spaces with hyphens → what-is-a-url-slug
4. Remove unnecessary words → url-slug (optional)

Result:
