About Slug Check
Score URL slugs against SEO best practices and auto-suggest the cleaned version.
Paste a slug to score it from 100 across six rules: lowercase only, hyphens not underscores or spaces, ASCII alphanumerics, no doubled or edge hyphens, under ~60 characters, and minimal stop-words. Every deduction is listed, plus a one-click cleaned suggestion.
Slugs are a minor ranking factor but a major usability one — readable URLs earn clicks and links. Everything runs in your browser.
Where it is used
Pre-publish CMS checks, auditing legacy URLs, teaching slug hygiene, and bulk-reviewing sitemaps.

Frequently Asked Questions
- Do keywords in URLs still matter?
- Slightly for ranking, a lot for click-through. Users read URLs in results — a clean slug wins the glance.
- Should I change old ugly URLs?
- Only with proper 301 redirects and a reason (rebrand, migration). Changing URLs for tidiness alone risks more than it gains.
- How long is too long?
- Past ~75 characters, truncation and dilution kick in. Three to five descriptive words is the sweet spot.
