A URL slug is the readable part of a web address that appears after the domain name. It helps identify a specific page and makes URLs easier for users and search engines to understand.
For example, in the URL:
The slug is:
what-is-a-url-slug
These page identifiers are commonly used for blog posts, product pages, landing pages, category pages, and other website content.
Why Are URL Slugs Important?
Clean, descriptive page URLs make links easier to read, share, and understand. They also help organize website content and create a more professional appearance.
Compare the following examples:
| Good Example | Less Helpful Example |
|---|---|
| how-to-count-words | page123 |
| remove-line-breaks | article-98472 |
| best-home-gym-equipment | post?id=567 |
| title-case-vs-sentence-case | page-12-final-version |
The examples on the left immediately communicate what the page is about, while the examples on the right provide little context.
What Makes a Good URL Slug?
A well-structured page address is usually:
- Short and descriptive
- Easy to read
- Relevant to the page content
- Written in lowercase
- Separated with hyphens instead of spaces

Common Mistakes
Using Excessively Long Addresses
Long URLs can be difficult to read and share.
Example:
how-to-learn-everything-you-need-to-know-about-page-url-structure-for-beginners
Shorter versions are usually easier to manage.
Using Special Characters
Characters such as &, %, #, and ! should generally be removed.
Using Spaces
Spaces are not used in web addresses. Hyphens are the standard separator.
Good:
how-to-count-words
Less ideal:
how to count words
Using Random Numbers
Random numbers and symbols often provide little information about the content of a page.
