Hreflang Auditor

Audit the reciprocity and compliance of your hreflang tags: missing return tags, invalid BCP-47 codes, x-default, self-reference. From a sitemap, a list or a URL.

Check that your hreflang tags reference each other (return tags), that codes are valid and that x-default and self-reference are in place. Sitemap and Pasted list modes: pure reciprocity audit, without crawling each page.

The 3 modes
  • Sitemap: audits the hreflang declared in an XML sitemap (few requests).
  • Pasted list: paste your declarations, zero request.
  • Single URL: one page and its alternates (capped).
What the tool detects
  • Missing return tag (reciprocity broken).
  • Invalid or duplicate BCP-47 codes, relative URLs.
  • Missing/multiple x-default and missing self-reference.
