What Is a URL Slug?

A URL slug is the human-readable part of a web address that identifies a specific page. In the URL https://textpire.com/tools/slug-generator, the slug is slug-generator. Slugs are used in blog posts, product pages, categories, and any page that benefits from a descriptive, memorable URL rather than a numeric ID like /page?id=42.

Why URL Slugs Matter for SEO

Google explicitly uses URL structure as a ranking signal. Clean, keyword-rich slugs are easier for search engines to index and for users to understand and share. A slug like /how-to-remove-line-breaks immediately tells both search engines and humans what the page is about. Compare this to /p?node=4817 — which communicates nothing. Well-crafted slugs also appear in search result snippets, improving click-through rates.

Slug Best Practices

  • Use hyphens, not underscores — Google treats hyphens as word separators but underscores as connectors. word-counter is parsed as two words; word_counter is treated as one.
  • Keep it short — Aim for under 60 characters. Shorter slugs are cleaner in search results and social shares.
  • Include the primary keyword — The most important keyword should appear in the slug, ideally near the beginning.
  • Use lowercase only — URLs are case-sensitive on most servers. Lowercase prevents broken link issues.
  • Remove stop words — Drop "a", "the", "and", "of" unless they are genuinely necessary for meaning.
  • Avoid special characters — Accented letters, spaces, and symbols cause encoding issues. This tool removes them automatically.

Kebab-case vs Snake_case for URLs

Kebab-case (words-separated-by-hyphens) is the overwhelmingly preferred format for URLs. Google's John Mueller has explicitly recommended hyphens over underscores for URLs. Snake_case (words_connected_by_underscores) is common in file names, Python variables, and database columns, but should generally be avoided for public-facing URLs unless your framework requires it.

How to Use This Tool

Paste or type your page title into the input field. The slug updates instantly. Optionally add your base domain to preview the complete URL. Copy the slug or full URL with one click. The tool automatically removes accented characters, special symbols, and extra spaces while converting to your chosen format.

Frequently Asked Questions

Should I use hyphens or underscores in URL slugs?

Hyphens. Google treats hyphens as word separators in URLs, improving how your keywords are parsed for search ranking. Underscores connect words into a single token, which can hurt keyword visibility. For SEO, always use kebab-case (hyphens) in public URLs unless your CMS specifically requires underscores.

How long should a URL slug be?

Aim for 3 to 5 words and under 60 characters. This tool shows a warning when your slug exceeds 60 characters. Shorter slugs are more shareable, easier to type, and display better in search result snippets. Long slugs do not provide additional SEO benefit beyond including your primary keyword.

Does capitalization matter in URL slugs?

Yes — URLs are case-sensitive on most Linux-based web servers (which host the majority of websites). /My-Page and /my-page are treated as different URLs. Always use all-lowercase slugs to avoid duplicate content issues and broken links when someone types the URL manually.

What happens to accented characters like é, ñ, or ü?

This tool normalizes accented characters by decomposing them and removing the accent marks. For example, "café" becomes "cafe" and "naïve" becomes "naive". This prevents percent-encoding in URLs (%C3%A9) which makes URLs ugly and harder to share.

Should I change slugs of existing pages?

Only with extreme caution. Changing a slug breaks the existing URL, destroying all backlinks, social shares, and bookmark traffic. If you must change a slug, always set up a 301 permanent redirect from the old URL to the new one. For new pages, always get the slug right before publishing.

Can I use numbers in slugs?

Yes, numbers are fully supported. Slugs like "top-10-text-tools" or "remove-line-breaks-2024" are perfectly valid. This tool preserves numbers in the output.

What about stop words like "the", "a", "and"?

This tool does not automatically remove stop words because context matters — sometimes they are meaningful. Review the generated slug and manually delete stop words that add length without adding meaning. For example, "how-to-remove-the-extra-spaces" can become "remove-extra-spaces".

Is it free?

Completely free with no account required. All slug generation happens in your browser with no data sent to any server.
