About

Hreflang Pro is an all-in-one hreflang auditor that checks an entire language/region cluster in one click — straight from the page you're on.

Most hreflang checkers look at a single page. Hreflang Pro builds the whole cluster: it reads hreflang from the HTML <head>, HTTP Link headers and XML sitemaps, fetches every alternate URL, and validates the set as a whole — then gives you a health score and the exact fix for every issue.

WHAT IT CHECKS
• Return tags — confirms every page links back (reciprocal hreflang)
• Self-referencing tags — flags pages that don't include themselves
• Invalid or mistyped codes — validates ISO 639-1 language and ISO 3166-1 region codes
• Canonical conflicts — spots canonicals that undermine your hreflang
• x-default — checks it's present, in-cluster and not redirecting
• Redirects & unreachable pages — finds alternates that 404, redirect or time out
• noindex conflicts — flags noindexed pages that still carry hreflang
• <html lang> and Content-Language mismatches
• Relative URLs and tags placed outside <head>
• Rendered vs raw HTML — an FYI when hreflang is injected client-side by JavaScript

WHAT YOU GET
• A 0–100 cluster health score
• A prioritised, plain-English issue list — what's wrong, which page, and the exact code to fix it
• A full cluster matrix showing every page × every language
• CSV export of the audit and the fixes

HOW IT WORKS
Open any page in the cluster and click the icon. Everything runs locally in your browser. No account, no sign-up, no tracking, and your browsing data never leaves your machine.
