How to Optimize a Multilingual Site for AIO Indexing

• Canonical: self-referential for each language version.
• hreflang: correct alternates (and x-default) between equivalents.
• Language: html lang, JSON-LD inLanguage, and visible language match.

Content-level alignment

Align core terms via the Glossary and use consistent naming and links across the site to reduce model confusion.
