What is a URL slug?

A URL slug is the part of a web address that identifies a specific page in a human-readable format. It appears after the domain and directory structure: in example.com/blog/how-to-write-better-code, the slug is how-to-write-better-code. Good slugs are short, descriptive, all-lowercase, and use hyphens rather than spaces or underscores.

Slug formatting rules

Lowercase only
URLs are case-sensitive on most servers. /Blog and /blog may point to different pages β€” always use lowercase.
Hyphens, not underscores
Google treats hyphens as word separators. Underscores join words, making "word_count" a single token rather than two.
No special characters
Accents, ampersands, and punctuation must be URL-encoded (%20, %26) which makes URLs hard to read and share.
Concise and descriptive
Include the primary keyword. Aim for 3–5 words. Shorter slugs are easier to remember, type, and share.
No stop words (often)
Articles like "a", "the", "and" can usually be removed. "how-to-build-website" is cleaner than "how-to-build-a-great-website".
Include target keyword
The keyword in the URL is a minor but confirmed Google ranking factor. Match it to your page title keyword.

Changing slugs on live pages: proceed with caution

Changing the URL of a published page breaks all existing links, bookmarks, and any Google ranking it has built up. If you must change a slug, set up a 301 permanent redirect from the old URL to the new one. Without a redirect, visitors and search engines encountering the old URL will receive a 404 error, losing both traffic and SEO equity.

Frequently asked questions

What is a URL slug?

A slug is the human-readable part of a URL that identifies a page, usually derived from its title β€” for example "my-first-post" in /blog/my-first-post. Clean slugs help both users and search engines understand the page.

What makes a slug SEO-friendly?

Keep it short, lowercase, and use hyphens between words. Include your main keyword, remove stop words where possible, and avoid special characters, spaces and underscores.

Why hyphens instead of underscores?

Google treats hyphens as word separators but underscores as joiners, so "blue-shoes" is read as two words while "blue_shoes" can be read as one. Hyphens are the SEO-recommended choice.

Does changing a slug affect SEO?

Yes β€” changing a published URL can lose existing ranking and break links. If you must change it, set up a 301 redirect from the old slug to the new one.
