About Slug Generator

A URL slug is the part of a web address that identifies a specific page in human-readable form. For the URL `https://example.com/blog/how-to-make-sourdough-bread`, the slug is `how-to-make-sourdough-bread`. Well-crafted slugs are crucial for SEO because search engines use the slug to understand what the page is about, and because clean, readable URLs improve click-through rates in search results and social shares.

Best practices for URL slugs include: use lowercase letters only (URL paths are case-sensitive on most servers); use hyphens to separate words, not underscores, since Google treats hyphens as word separators but treats underscores as word joiners; remove stop words like "a", "an", "the", "in" when they're not essential to the meaning; keep slugs short but descriptive, ideally under 60 characters; remove special characters, accents, and non-ASCII symbols; and avoid repeating the same word multiple times.

This tool converts any text into a clean slug by: lowercasing everything, converting accented characters to their ASCII equivalents (é → e, ñ → n, ü → u), removing all punctuation and special characters, collapsing multiple spaces into one, and joining words with your choice of separator: hyphen (default, most common for URLs), underscore (used in database column names and some Python conventions), or dot (used in some API naming conventions).

The slug preview updates as you type, making it easy to iterate quickly and find the right formulation.

Frequently Asked Questions

Should I use hyphens or underscores in URL slugs?
Hyphens are strongly preferred for SEO. Google's John Mueller has confirmed that Google treats hyphens as word separators, meaning 'how-to-cook-pasta' is indexed as four distinct words. Underscores are treated as word joiners, so 'how_to_cook_pasta' is indexed as the single term 'howtocookpasta'. Use underscores only when required by a specific technical convention.
How are accented characters handled?
Accented and diacritical characters are transliterated to their closest ASCII equivalent before slugifying. For example, 'é' becomes 'e', 'ñ' becomes 'n', 'ü' becomes 'u', and 'ß' becomes 'ss'. This ensures slugs remain URL-safe without percent-encoding, which can make URLs look cluttered.
Should I remove stop words from a slug?
For most blog posts and pages, keeping stop words ('how to', 'what is') actually helps with conversational and long-tail keyword queries. Remove them only if the slug becomes unnecessarily long. The slug for 'How to Make Sourdough Bread' is fine as 'how-to-make-sourdough-bread', with no need to shorten it to 'make-sourdough-bread'.
What is the maximum recommended slug length?
Most SEO tools recommend keeping slugs under 60 characters and including the main keyword as early as possible. Google does not impose a hard technical limit, but very long slugs (over 100 characters) can appear truncated in search result URLs and look untrustworthy to users.
