What Does the Hreflang Validator Check?
The validator parses hreflang link tags from HTML and checks for structural and semantic correctness: valid ISO 639-1 language codes, valid ISO 3166-1 region codes, absolute HTTPS URLs, x-default presence, self-reference, duplicate locale detection, and duplicate URL detection across locales.
Need to generate hreflang tags instead of validating them? Use our hreflang tag generator to build reciprocal tag sets from scratch.
