What is a URL slug?

A URL slug is the last part of a URL that identifies a specific page or resource in a human-readable way. In https://example.com/blog/my-awesome-post, the slug is my-awesome-post. Good slugs are short, descriptive, all-lowercase, hyphen-separated, and contain the primary keyword. They’re a small but real SEO ranking factor and dramatically affect user experience – readable slugs like /best-headphones-2026 are remembered, shared, and trusted more than cryptic ones like /p?id=18394. This generator converts any title or text into an SEO-friendly slug instantly, handling special characters, accents, stop word removal, and length constraints automatically.

How to use this tool

1. Enter text or title — Type or paste your article title, product name, or any text you want to convert.
2. Choose separator — Hyphen (-) is Google’s preference and most common. Underscore (_) is sometimes used but Google treats words separated by underscore as one word, hyphens as separate words.
3. Toggle options — Lowercase (recommended). Remove stop words (a, the, of, in…) for cleaner slugs.
4. Set max length — 0 = no limit. Aim for under 60 characters – longer slugs may get truncated in search results and look ugly.
5. Copy the slug — Big text box shows the result. Copy button puts it on your clipboard, ready to paste into your CMS.

How the slug is generated

1. Normalize Unicode – strip accents (café → cafe, naïve → naive)
2. Lowercase (if enabled)
3. Strip special characters – keep only letters, numbers, spaces
4. Remove stop words (if enabled) – ‘a’, ‘an’, ‘the’, ‘and’, ‘or’, etc.
5. Replace spaces with separator – default hyphen
6. Truncate to max length at word boundary

Example transformation: ‘The Best 10 Headphones (2026 Review)!’

→ Lowercase: ‘the best 10 headphones (2026 review)!’

→ Strip special: ‘the best 10 headphones 2026 review’

→ Remove stop words: ‘best 10 headphones 2026 review’

→ Replace spaces: ‘best-10-headphones-2026-review’

Examples

• ’10 Tips for Working from Home (2026 Edition)’ → 10-tips-working-home-2026-edition
• ‘How to Make Pasta – A Step-by-Step Guide’ → how-to-make-pasta-step-by-step-guide
• ‘¿Qué es JavaScript?’ → que-es-javascript (accents stripped)
• ‘iPhone vs Samsung Galaxy: Which is Better?’ → iphone-vs-samsung-galaxy-which-better
• ‘Product #5482 / Color: Red / Size: XL’ → product-5482-color-red-size-xl

Tips & best practices

• Keep slugs under 60 characters – longer slugs are truncated in search results and look unprofessional
• Use hyphens, not underscores – Google treats hyphen-separated as separate words (better for SEO) but treats underscored as one word
• Always lowercase – some servers treat /Page and /page as different URLs, causing duplicate content issues
• Include your primary keyword in the slug – small but real SEO signal
• Avoid dates in evergreen content slugs – /how-to-cook-pasta is better than /2024-how-to-cook-pasta which dates the content
• Don’t change slugs after publishing – set up 301 redirects if you must, or you’ll lose all SEO equity and backlinks
• Stop words removal is optional – usually clean but ‘how-to-cook’ may not need stripping

Limitations & notes

This generator doesn’t check for slug uniqueness in your database – your CMS should append a number (e.g. -2) for duplicates. Some languages with non-Latin scripts (Chinese, Arabic, Hindi) get transliterated based on browser locale – results may not be ideal for those scripts. For SEO-sensitive multilingual sites, consider using language-specific URL paths instead of transliteration.

Frequently Asked Questions

What characters can a URL slug contain?

Per RFC 3986: letters (a-z, A-Z), digits (0-9), and these symbols: -, ., _, ~. In practice, stick to lowercase letters, digits, and hyphens for best compatibility. Avoid: spaces (URL-encoded to %20), special characters (need encoding), uppercase (causes case-sensitivity issues).

Why hyphens instead of underscores?

Google explicitly treats hyphens as word separators (so ‘my-cool-post’ is read as three words) but treats underscores as part of one word (so ‘my_cool_post’ is read as one word ‘my_cool_post’). Hyphens are better for SEO ranking on individual words.

How long should a URL slug be?

60 characters max as a soft rule. Google search results display about 75 characters of URL before truncation. Shorter slugs are easier to share, remember, type, and look better. 3-7 words is ideal.

Should I include stop words like ‘the’, ‘and’?

Optional – both ways work. Removing stop words gives cleaner, shorter slugs (/best-coffee instead of /the-best-coffee). Keeping them is fine if it makes the slug more readable. Google handles both. Consistency across your site matters more than which choice you make.

What happens if I change a slug after publishing?

All existing links and search engine indexes break! You lose SEO equity for that URL. If you must change, set up a 301 (permanent) redirect from old to new URL so links and SEO transfer. Most CMS platforms (WordPress, Webflow) do this automatically when you change a slug.

Can I use Unicode characters in slugs?

Technically yes (Punycode-encoded for the URL), but practically no. Browsers display them inconsistently, links break when copy-pasted to non-Unicode systems, social shares get mangled. Always transliterate or use English equivalents.

Does slug affect SEO ranking?

Yes, slightly. Including primary keyword in slug is a minor positive ranking signal. But content quality, backlinks, and user experience are 100x more important. Don’t obsess over slug optimization – just keep them short, descriptive, and keyword-aware.
