The basics are separate URLs per language (/en/, /ja/, /zh-tw/) with hreflang, a title, description and H1 for each language, body text written with local keywords, and structured data per language.
Pages that were only machine-translated don't match local search terms and don't rank well. Measure AI answers separately for each language to see which language is weak.
How MAKE Marketing uses it
