FAQ

    
What is a URL slug?
A slug is the readable part of a URL (often the last segment) that identifies a page, like my-post-title.
What characters should a slug contain for SEO?
Usually lowercase letters, numbers, and hyphens. Avoid spaces, underscores, and special symbols.
Can I paste a full URL instead of just the slug?
Yes. The tool extracts the URL path (and can optionally check only the last segment) before validating.
Why avoid uppercase letters in slugs?
Lowercase prevents inconsistent URLs and reduces redirect/canonical issues across systems that treat case differently.
How long should a slug be?
Short and descriptive is best; many teams aim for ~60–80 characters. This tool can warn when your slug is long.
Does the checker fix accents and Unicode characters?
It generates a suggestion that strips common diacritics (e.g., café → cafe) and removes unsafe symbols.
Does this tool send my URLs to a server?
No. It runs fully in your browser and doesn’t make network requests.
