Frequently Asked Questions
Invalid characters (anything besides lowercase letters, numbers, and hyphens), slugs over 60 characters, and underscores used instead of hyphens.
Google has confirmed it treats hyphens as word separators in URLs but treats underscores as part of the word itself, so "best-practice-slug" reads as three words while "best_practice_slug" reads as one long token.
This tool flags anything over 60 characters as too long, since shorter, keyword-focused slugs are easier to read in search results and share cleanly on social media.
Yes — if issues are found, it displays a cleaned version alongside the list of problems, with characters lowercased, invalid symbols and repeated hyphens stripped, and leading/trailing hyphens trimmed.
