❓ FAQ

Is x-default required?

Not required but recommended by Google. It is the fallback shown when no locale matches.

Where should hreflang go?

HTML , HTTP header, or XML sitemap. Sitemap is easier for large sites.

Are bidirectional links required?

Yes. A→B and B→A must both declare hreflang. Google ignores one-sided links. This tool emits full bidirectional sets.
