Multilingual / Hreflang Debugger

Check language relationships, return links and canonical conflicts across supplied pages.

Up to ten public URLs, one per line. Only supplied pages are fetched.

One server job runs at a time. Private reports last up to 24 hours; the shared history retains at most 500 finished jobs. Download evidence you need to keep. Jobs have a three-minute execution budget; limits may stop a complex page earlier.

Verify a domain for origin checks, browser actions or webhook delivery

Publish the unique value in a DNS TXT record or a small file on your HTTPS website. Verification lasts 24 hours in this browser session.

What you can investigate

Check language relationships, return links and canonical conflicts across supplied pages. Review the affected endpoint or page, the measurement time and the suggested next action before changing your site.

Scope and privacy

Inputs and results are encrypted in our database and tied to this browser’s private ownership cookie. Only public destinations are allowed. Reports last up to 24 hours within the shared 500-report history; private recovery backups have a separate lifetime.

Only the supplied URLs are fetched, with bounded redirects and body size. Analysis uses HTTP HTML and headers without JavaScript. Hreflang inspection covers HTML and HTTP Link declarations; it does not crawl the site or parse sitemap language clusters.
