Hreflang Checker: Review the Language Versions Your Page Declares

See the alternate-language links present after rendering so you can spot duplicate, missing, or unexpected hreflang declarations before international pages compete with each other.

One public URL. One bounded report. No whole-site crawl.

Keep international page signals clear

Submit one public URL to receive a focused technical SEO report.

Keep international page signals clear

  1. 1Paste one public page URL.
  2. 2Render the page after JavaScript loads.
  3. 3Review its alternate-language declarations.

Canonical Tag Checker: Confirm the URL Search Engines Should Prefer

Check one public page before publishing, migrating, or investigating duplicate-content signals. See the rendered canonical tag beside the final page URL.

HTTP Header Checker: See the Response Signals Behind Your Page

Inspect one public URL without a full site crawl. Check the response headers that affect caching, content handling, and crawler instructions.

XML Sitemap Checker: Check One Sitemap Before You Rely on It

Paste the direct URL of an XML sitemap to inspect its format, top-level entries, duplicate locations, and basic delivery signals. It never crawls the URLs inside.

Frequently asked questions

Does this test reciprocal hreflang tags?

No. It reads the declarations on the submitted page only and does not fetch alternate URLs.

What is x-default?

It is an optional hreflang value used for a fallback page when no language or region version is the best match.

Why are duplicate hreflang values a problem?

Repeated language or region declarations can make your intended alternate targeting unclear.
