Slug Generator
Convert any title into a clean, SEO-friendly URL slug. Handles accented characters, custom separators, lowercase toggling, and length limits for WordPress, Ghost, and static sites.
Why Use Slug Generator?
A URL like `example.com/post/3487` tells Google and readers nothing, while `example.com/post/best-free-ai-seo-tools-2026` signals the topic at a glance. Hand-writing slugs is tedious once you factor in stripping punctuation, lowering case, converting `é → e`, and cutting stop words — and a single typo is hard to fix once the URL is indexed. A slug generator automates all of that in one shot, and the preview lets you see the final URL before you commit it to a CMS, where changing it later risks broken links and lost SEO authority.
How to Use Slug Generator
- Type or paste the title, headline, or any text you want to convert into the input field.
- Customize options: choose a separator (hyphen, underscore, or dot), toggle lowercase, remove numbers, or set a max length.
- The slug is generated in real-time below the input. Copy it and use it in your website URLs.

About Slug Generator
The Slug Generator converts any text into a clean, SEO-friendly URL slug that's safe to use in web addresses. A good URL slug is crucial for search engine optimization (SEO) because it tells both users and search engines what the page is about. Our generator automatically handles Unicode normalization (converting accented characters like 'é' to 'e'), removes special characters, and replaces spaces with your chosen separator. You can customize the separator style (hyphens for SEO, underscores for file names, dots for versioning), enforce lowercase, remove numbers, and set a maximum character length. The tool even previews the full URL so you can see exactly how your slug will look in the browser's address bar.
Troubleshooting & Common Issues
Slug is too long to fit in meta tags
Set a max-length of 50-60 characters. Google's blue-link title only shows about 60 chars of URL before truncating, so longer slugs add no SEO value. Trim filler words ("the", "and", "a") from the source title first, then re-generate.
Non-English characters became `-` or disappeared
Unicode NFD normalization only covers letters with combining accents (é, ü, ñ). Characters from non-Latin scripts (Chinese, Arabic, Cyrillic) have no ASCII equivalent and get stripped. For those languages, transliterate manually (e.g., "北京" → "beijing") before generating.
Two slugs collide on the same CMS
Most CMS platforms auto-append `-2`, `-3` etc. to duplicates, which looks amateurish. Check for existing slugs before publishing and add a distinguishing word (year, version, or category) rather than relying on the auto-suffix.
Google still indexes the old URL after I changed the slug
Changing a slug creates a new URL — old inbound links will 404 unless you set up a 301 redirect from the old path to the new one. Check your CMS's redirect manager, or add a rule to your `vercel.json`, `nginx.conf`, or `_redirects` file.
Frequently Asked Questions
What is a URL slug?
A URL slug is the part of a web address that comes after the domain name and identifies a specific page in a human-readable form. For example, in 'example.com/my-awesome-blog-post', the slug is 'my-awesome-blog-post'.
Why are hyphens preferred over underscores in slugs?
Google treats hyphens as word separators but treats underscores as word joiners. So 'my-blog-post' is seen as three words by Google, while 'my_blog_post' is treated as one word. Using hyphens is the SEO best practice.
Does the slug generator handle non-English characters?
Yes! The generator normalizes Unicode characters, converting accented letters like 'ü', 'ñ', and 'é' to their ASCII equivalents ('u', 'n', 'e'). This ensures your slugs are universally compatible.
What's the ideal slug length for SEO?
Google displays up to about 60 characters in search results. Most SEO experts recommend keeping slugs under 60 characters and using 3-5 descriptive words. Our max length option helps you enforce this limit.
