The Hreflang HTML Tag (<link rel="alternate" hreflang="..." href="..." />) instructs search engine crawlers which language and regional URL variant to display based on the user's geolocation and browser locale settings.
Hreflang attribute values must follow ISO 639-1 language codes combined optionally with ISO 3166-1 Alpha-2 region codes (e.g. es-ES for Spanish in Spain or en-US for English in the United States).
Search engines strictly enforce reciprocal linking validation: every alternate language page MUST contain a matching hreflang reference pointing back to all other language versions, alongside an x-default tag for unmatched browser locales.
