URL slugs are the clean, hyphenated versions of page titles used in web addresses — "How to Build a REST API" becomes how-to-build-a-rest-api. This batch generator processes hundreds of titles in a single operation, applying consistent rules for spaces, special characters, accented letters, and stop words — saving hours of manual slug cleanup when migrating or building a content site.
A well-formed slug is lowercase, uses hyphens (not underscores or spaces) as separators, contains no special characters or percent-encoding, and ideally excludes common stop words like "a", "the", and "and" that add no SEO value. Accented characters (é, ü, ñ) should be transliterated to their ASCII equivalents. Consecutive hyphens and trailing hyphens should be collapsed. This generator applies all these rules automatically.
Google historically treats hyphens as word separators (like spaces) and underscores as word joiners. "best-tools" is two words; "best_tools" is one word. Use hyphens for better SEO.
For most SEO-targeted slugs, omit stop words to keep the URL short and keyword-dense. However, for human readability or exact-title matching, keeping them can be appropriate.
They are transliterated to their closest ASCII equivalent: é → e, ü → u. This ensures URLs are ASCII-safe and readable without percent-encoding.
Best practice is under 75 characters. Very long slugs dilute keyword signal and are hard to share. Use the max-length option to truncate at a word boundary.
