How to use this hreflang checker

  1. Enter a full https URL without query parameters.
  2. Review language codes (for example en, en-US, es-MX or x-default). en-UK is a common mistake; use en-GB.
  3. Confirm a self-reference, an x-default when two or more languages are listed, and return links on the alternate pages.

Run the check

Public HTTP(S) URLs only, no query strings. Rate limits apply.

Check every language version

Questions

Do you crawl every language version?

No. This check fetches the submitted page and at most five unique alternate URLs, with the same SSRF and size limits as the other tools.

Does a site without hreflang fail?

No. A single-language site does not need hreflang annotations. The tool simply reports that none were found.

Do I need an account?

No. These tools work without signing in. Rate limits apply per visitor.

Does Traffivio change my site?

No. Server tools only fetch public URLs. Counters run entirely in your browser.
