A practical method for localizing the structured data your theme actually renders — product specs, materials, sizing charts, and metaobject sections — without breaking the schema.
Sizing charts, ingredients, materials, and spec tables usually live in metafields. If you only translate titles and descriptions, these stay in the source language.
FAQs, lookbooks, and brand sections are built as metaobject entries — each one needs a per-market version to feel fully localized.
Theme sections render metafield values across product and collection pages, so gaps show up everywhere the moment you go multilingual.
