About hreflang
hreflang annotations tell search engines which language and region each version of a page targets, so a French user sees the French page and a UK user the UK one. They are essential for multilingual and multi-regional sites.
A valid cluster is bidirectional and self-referencing: every page lists all its alternates and itself, ideally with an x-default for unmatched users, using correct ISO language (and optional region) codes. This validator fetches the live page and checks each of those requirements.

What does the hreflang validator check?
It fetches the page, reads every hreflang tag, validates the language and region code format, and checks for a self-referencing tag and an x-default fallback.
What makes an hreflang cluster valid?
It must be bidirectional and self-referencing: each page lists all its alternates and itself, using correct ISO codes, ideally with an x-default.
What is x-default for?
It is the fallback shown to users whose language or region does not match any listed version. It is recommended but not required.
Is the check live?
Yes. The page is fetched server-side in real time, so CORS never blocks reading its tags.
