AI ショッピング時代の多言語 EC ローカライズ:文章ではなく商品事実を現地化する
AI ショッピングでは、市場ごとの商品事実、ポリシー、コンテンツ、計測シグナルが比較されます。DTC ブランドの多言語対応は翻訳だけでは足りません。
ローカル検索意図、商品事実、Product JSON-LD、Merchant Center データ、ポリシー、分析をそろえて商品ページを最適化する方法。

ローカライズ商品ページは翻訳だけではなく、現地の検索意図、商品事実、構造化データ、merchant data、ポリシー、分析を一貫させるページです。

Plan the page from the local query and local buying objections. Define the attributes buyers compare in that market, the units and size conventions they expect, the proof they trust, and the internal links that keep them inside the same locale.
Visible copy, Product JSON-LD, Merchant Center data, and checkout should describe the same product. Check title, description, price, currency, availability, variants, images, brand, identifiers, shipping, returns, and policy context before publication.
Google product structured data and merchant listing structured data help systems understand product facts for richer product experiences when eligible. The localized page should carry the same facts that the buyer can see.
Google Merchant Center landing page guidance emphasizes accurate product information, including price and availability, on the landing page. Product data specification checks make feed-page consistency a core operating requirement.
Hreflang helps Google understand alternate localized versions. Each localized PDP should have a clear purpose, self-canonical URL when indexable, real localized content, and same-locale internal links where possible.
Localize reviews, size charts, units, delivery windows, duties, returns, warranty language, payment expectations, and imagery. Product pages answer more buying questions when proof and policies fit the market.
Foundax connects product records, localized pages, SEO metadata, Product JSON-LD, Google Merchant Center preflight and sync, Search Console workflows, sitemap behavior, Content Studio, and first-party analytics in one workflow.
They are one layer. Localized product pages also need local search intent, structured data, merchant data consistency, policy clarity, hreflang, and market-level measurement.
Start with SKUs that already receive international traffic, have strong margin, create support questions, or appear in Merchant Center warnings.
Foundax lets teams review localized content, product records, SEO metadata, Product JSON-LD, Google workflows, and first-party analytics together before and after publication.
