Hreflang Implementation Best Practices
Recommended
- Use valid BCP 47 language codes (e.g.,
en,es-ES,de-DE). - Include a self-referencing
hreflangtag pointing to the current page. - Ensure bidirectional reciprocal return tags between language variations.
- Add an
x-defaulttag for unmatched language fallback users.
Avoid
- Do not declare multiple conflicting target URLs for the same language code.
- Avoid pointing
hreflangtags to 404 or redirected pages. - Do not use invalid ISO country codes instead of language codes.
- Avoid broken reciprocal links between localized site versions.
