About Hreflang Tag Checker
Hreflang Tag Checker fetches a page and reads its alternate hreflang link tags, the ones that tell search engines which language and region each version of a page targets, checking each one's format and flagging duplicates.
Use this on a multi-language or multi-region site to confirm the tags are actually well formed, since a single malformed hreflang code can cause search engines to ignore the entire set for that page.
This checks the tags declared on the one page you give it. It cannot confirm that the pages they point to link back reciprocally, which search engines also expect and which requires checking every linked page in turn.
