About This Check

Checks whether hreflang tags are present for multilingual or multi-regional pages.

Why This Matters

LLM Discoverability

hreflang tags tell AI language models which URL to prefer for a given locale–language combination, reducing the chance of an AI returning the wrong language variant to a user.

SEO Impact

Correct hreflang implementation prevents duplicate content penalties in multilingual sites and ensures the appropriate language/region variant ranks in each target market.
