A URL slug is the human-readable portion of a web address that identifies a specific page. For the URL 'example.com/blog/seo-friendly-url-slugs', the slug is 'seo-friendly-url-slugs'. Well-crafted slugs are concise, descriptive, all-lowercase, and use hyphens as word separators — a format that is both readable by humans and optimal for search engine indexing.
Creating slugs manually is error-prone: accented characters like é, ñ, and ü must be transliterated to their ASCII equivalents, special symbols must be stripped or replaced, consecutive spaces become single hyphens, and the result must be lowercase. Miss any of these steps and you risk broken links, inconsistent URLs, or SEO penalties from non-canonical URLs.
This Slug Generator automates the entire process. Paste any title, heading, or phrase and get a perfectly formatted URL slug in one click. The tool handles transliteration of accented and Unicode characters so that 'Café au Lait' becomes 'cafe-au-lait' rather than a URL-encoded mess. Read on to understand slug best practices and how to configure the tool for your CMS.
What Is a URL Slug?
A URL slug is the last segment of a URL path that identifies a unique resource on a website. Unlike query strings or hash fragments, slugs are part of the canonical URL path and are indexed by search engines as meaningful signals about page content.
The term 'slug' comes from newspaper publishing, where it referred to the short identifier given to an article for internal tracking. In web publishing, the slug carries the same identifying function but in the URL structure.
Good slugs follow these rules: they are all lowercase, use hyphens (not underscores) as word separators, contain no special characters or spaces, are as short as possible while remaining descriptive, and include the primary keyword for the page. URL slugs that follow these conventions improve click-through rates from search results and reduce the risk of duplicate content issues.
How to Use This Tool
Generating a URL slug takes seconds:
- 1
Enter your title or phrase
Type or paste the page title, blog post heading, or product name that you want to convert into a URL slug.
- 2
Review the generated slug
The tool instantly shows the generated slug. Spaces become hyphens, uppercase letters become lowercase, accented characters are transliterated to ASCII, and non-alphanumeric characters are removed.
- 3
Customize the separator (optional)
Choose between hyphens (recommended for SEO) or underscores as word separators. Most CMS platforms and SEO guidelines recommend hyphens.
- 4
Remove stop words (optional)
Toggle 'Remove stop words' to strip common words like 'the', 'a', 'and', 'of' from the slug. This creates shorter URLs but may reduce human readability.
- 5
Copy the slug
Click Copy to copy the generated slug. Paste it directly into your CMS's permalink field, your routing configuration, or your database.
Common Use Cases
Slug generation is essential for anyone managing web content:
- Blog post URLs: convert post titles into clean, keyword-rich URLs for WordPress, Ghost, or custom CMS platforms.
- E-commerce product pages: generate consistent slugs for product names that may contain special characters, brand names, or accented letters.
- Documentation sites: create predictable, human-readable URLs for technical documentation pages.
- API endpoint design: generate RESTful URL path segments from resource names following consistent conventions.
- Multi-language sites: transliterate titles in non-Latin scripts to ASCII slugs that work in all browsers and HTTP clients.
Tips and Best Practices
Create effective URL slugs that rank well and avoid common pitfalls:
- Keep slugs under 60 characters: shorter URLs are easier to share, remember, and display fully in search result snippets.
- Include the primary keyword: place your most important keyword near the beginning of the slug for maximum SEO benefit.
- Avoid stop words in short slugs: for brief URLs, removing 'the', 'a', 'of' saves characters without affecting meaning. For longer, more descriptive slugs, stop words can aid readability.
- Never change a published slug without a redirect: changing a URL breaks inbound links and loses accumulated PageRank. Always set up a 301 redirect from the old URL to the new one.
- Use hyphens, not underscores: Google treats hyphens as word separators (so 'blue-widget' is indexed as two words) but treats underscores as connectors ('blue_widget' is one word). Hyphens are universally recommended.
Frequently Asked Questions
What characters are allowed in a URL slug?
URL slugs should contain only lowercase letters (a-z), digits (0-9), and hyphens. All other characters — including spaces, special symbols, and accented letters — should be removed or transliterated. This ensures the URL is valid in all browsers and HTTP clients without percent-encoding.
Should I use hyphens or underscores in URL slugs?
Use hyphens. Google's official guidance confirms that hyphens act as word separators in URLs, which helps the search engine understand your content. Underscores join words together from Google's perspective, which can reduce keyword relevance.
How does the tool handle accented characters like é, ñ, or ü?
The tool uses Unicode transliteration to convert accented characters to their closest ASCII equivalents: é becomes 'e', ñ becomes 'n', ü becomes 'u'. This produces a clean ASCII slug without losing the phonetic meaning of the original word.
Does removing stop words improve SEO?
Removing stop words shortens the URL and keeps the keyword more prominent, which can marginally help SEO. However, for readability and social sharing, keeping stop words that are part of the natural phrase (like 'how-to') is often better than removing them.
Can I generate slugs for non-English titles?
Yes. The tool transliterates characters from many Unicode scripts (including Cyrillic, Greek, and Latin-extended) to ASCII. For scripts like Chinese, Japanese, or Arabic, transliteration produces phonetic romanizations, which may need manual review.
What should I do if two pages would have the same slug?
Append a distinguishing suffix, typically a number (e.g., 'my-article-2') or a date (e.g., 'my-article-2025'). Most CMS platforms handle this automatically, but for custom systems you need to check slug uniqueness at save time.
Is the generated slug guaranteed to be unique?
No. This tool generates the correctly formatted slug from your input text but does not check your database or CMS for uniqueness. You must verify uniqueness within your own system before publishing.
