Hreflang best practices
Every URL must reference every other URL
Hreflang is a two-way relationship. If page A references page B, page B must also reference page A, and all other language variants.
Use the correct language-region format
Use ISO 639-1 language codes (en, fr, de) and optionally ISO 3166-1 alpha-2 region codes (GB, US, DE). So en-GB, fr-FR, de-AT, etc.
Always include x-default
Set x-default to the URL you want to serve when no language or region matches — usually your main English or global page.
Self-reference is mandatory
Each page must include a hreflang tag pointing to itself. Omitting the self-referential tag can cause implementation errors.
