What Makes a Good URL Slug?

A good slug is lowercase, uses hyphens to separate words, removes special characters, and is concise. Good slugs improve SEO and make URLs readable. Keep slugs under 60 characters for best results.

Frequently Asked Questions

How do I convert a blog post title to a URL slug?

Type or paste the title into the input field. The slug is generated in real time: spaces become hyphens (or underscores, your choice), special characters are removed, letters are lowercased, and consecutive separators are collapsed into one. A preview URL shows how the slug will look as part of an actual path like https://example.com/posts/your-post-slug.

What makes a good SEO-friendly URL slug?

A good slug is lowercase, uses hyphens to separate words (hyphens are preferred over underscores by search engines), contains only ASCII alphanumeric characters, and is as short as possible while still describing the page content. Keep slugs under 60 characters and avoid stop words like ‘a’, ‘the’, and ‘of’ when they add length without adding relevance.

Does this slug generator handle non-ASCII characters like accented letters?

Yes. The generator transliterates common accented and special characters (é → e, ü → u, ñ → n, etc.) before processing. This ensures slugs remain ASCII-safe for maximum compatibility with web servers, CDNs, and databases that may not handle multibyte characters in URL paths reliably.

Should I use hyphens or underscores in URL slugs?

Use hyphens. Google historically treats hyphens as word separators and underscores as character joiners, meaning ‘hello-world’ is indexed as two separate words while ‘hello_world’ is indexed as one. Major SEO guidelines and CMS platforms default to hyphen-separated slugs for this reason.

Is my input text processed on a server?

No. The slug conversion runs entirely in your browser using JavaScript. Input text is never sent to any server. The generation updates live as you type, with no network request involved.
