How to set up schema markup for a multilingual website

Question

Accepted Answer

To implement schema markup effectively on a multilingual website, you must apply specific schema to each individual localized page. Crucially, every schema block should include the inLanguage property, accurately indicating the content's language and region, for instance, "en-US" or "fr-CA". Ensure that the URL specified within each schema directly corresponds to that particular language version of the page. While schema markup itself does not replace hreflang for linking language variants, it provides search engines with vital context about the content's linguistic nature. Maintain consistency in the underlying entity (e.g., Product, Article) described across all language versions, even if the descriptive text changes. The core principle is to furnish detailed, language-specific schema for every unique page URL to enhance discoverability.
