Hreflang Tag Checker
Running a multilingual or multi-regional website? Verify that your hreflang tags correctly guide both users and search engines to the right language version.
What the tool checks
- Presence and syntax of hreflang attributes
- Valid language and region codes (e.g. en-GB, es-MX)
- Reciprocal (bidirectional) linking between language versions
- x-default tag for the fallback version
- Common errors: missing return links, invalid locale codes
Why it matters
Hreflang tells Google which language version of a page is meant for which audience. Without it, the wrong language version may appear in search results, versions compete against each other for rankings, or they get flagged as duplicate content. For international sites, it's non-negotiable.
Detailed guide in the help centerFrequently asked questions
What is hreflang?
An HTML attribute that signals to search engines which language and region each version of a page targets, ensuring users see the correct locale in search results.
Do hreflang tags need to be reciprocal?
Yes. If page A references page B, page B must also reference page A. Google ignores one-sided hreflang annotations.
What is x-default used for?
It designates the default fallback page for users whose language or region doesn't match any specific hreflang variant.
