SEO checker

The page is fetched on the server (e.g. Vercel), so there are no browser CORS limits. Results cover SEO basics and share-style previews.

URL

Must be public http or https — localhost and private IPs are blocked in this tool. Share a direct link with ?url= — for example /seo-checker?url=https%3A%2F%2Fexample.com — and analysis runs automatically.
