Slug Generator — Complete Guide
A URL slug is the part of a web address that identifies a specific page in a readable way. For example, in the URL yoursite.com/blog/how-to-bake-bread, the slug is how-to-bake-bread. Well-formed slugs use only lowercase letters, numbers, and hyphens — no spaces, no special characters, no uppercase.
Getting slugs right matters more than most people realize. Search engines use the slug as a signal about what a page covers. A clean, descriptive slug like /best-coffee-shops-london is better for SEO than /page?id=4871. It's also easier to read and share.
This tool converts any text into a properly formatted slug instantly. Paste in a blog title, product name, or any phrase and it strips special characters, replaces spaces with hyphens, and lowercases everything.

Frequently asked questions
What characters are allowed in a URL slug?
Slugs should only contain lowercase letters (a-z), numbers (0-9), and hyphens (-). Spaces, special characters, and uppercase letters should all be removed or replaced.
Should I use hyphens or underscores in slugs?
Use hyphens. Google treats hyphens as word separators, which helps with keyword recognition. Underscores join words together, so best_coffee becomes one unit rather than two.
How long should a slug be?
Keep it as short as possible while still being descriptive. Most SEO guides recommend under 60 characters. Remove stop words like 'a', 'the', 'and' to shorten without losing meaning.
Can I change a slug after publishing?
You can, but you should set up a 301 redirect from the old URL to the new one. Without a redirect, any existing links to the old URL will return a 404 error.
