URL Slug Generator — Create SEO-Friendly URL Slugs Online

A URL slug is the part of a web address that identifies a page in human-readable form. For example, in https://example.com/blog/how-to-create-seo-slugs, the slug is how-to-create-seo-slugs. Our free online Slug Generator converts any title, headline, or string into a properly formatted URL slug — instantly and privately in your browser.

What Makes a Good URL Slug?

URL slugs affect both usability and SEO. Google uses the slug as a lightweight relevance signal, and users judge destination trustworthiness based on URLs before clicking.

A good URL slug:

• Uses lowercase letters only
• Replaces spaces with hyphens (-)
• Removes special characters (&, @, ?, #, etc.)
• Removes stop words optionally (a, the, and, of)
• Is short and descriptive (3–5 meaningful words is ideal)
• Matches the primary keyword of the page

Examples:

SEO Slug Best Practices

Do Use Hyphens, Not Underscores

Google treats hyphens as word separators but treats underscores as word connectors. css-grid-tutorial signals three separate keywords; css_grid_tutorial is read as one compound word cssgridtutorial. Always use hyphens.

Keep Slugs Short

Shorter URLs are more shareable, easier to remember, and look cleaner in search results. Google truncates URLs displayed in search results at around 60–70 characters. Studies show URLs under 60 characters have higher click-through rates.

Include Your Primary Keyword

The slug should match the primary keyword you’re targeting. If your article targets “javascript array methods”, your slug should be /javascript-array-methods/ — not /top-10-tips-to-improve-your-javascript-code/.

Avoid Date-Stamped Slugs

Avoid slugs like /2026/03/best-tools.html. Evergreen slugs like /best-developer-tools/ don’t become outdated and are easier to keep ranking long-term.

Frequently Asked Questions

Should I include numbers in slugs?

Yes, if the number is meaningful and part of the keyword. /top-10-css-tricks/ or /react-18-features/ benefit from including the number because users specifically search for it. But generic serial numbers in slugs (like /post-12345/) add no SEO value.

Can I change a slug after publishing?

Yes, but you must set up a 301 redirect from the old URL to the new URL. Changing a slug without a redirect causes a 404 error, breaks backlinks, and loses all accumulated link equity. If you must change a slug, update it, create the redirect, and update all internal links to the new URL.

Should the slug match the page’s <title> tag exactly?

Not necessarily. The <title> tag can be longer and more descriptive for click-through rate. The slug should be a distilled, keyword-focused version. For a title like “15 Expert Tips to Improve Your CSS Skills in 2026”, a good slug might be /improve-css-skills/.

What about non-ASCII characters (accents, CJK characters)?

For non-English content, you have two options: (1) transliterate to ASCII equivalents (e.g., “résumé” → resume) for maximum browser/sharing compatibility, or (2) use encoded Unicode slugs for native-language SEO targeting. Our tool provides ASCII transliteration by default.

Does slug length affect Google rankings?

Google has stated that excessively long URLs can be problematic but that there’s no specific character limit for ranking. However, research consistently shows that shorter, keyword-rich URLs correlate with higher rankings and better click-through rates. Aim for 3–5 words in your slug.
