How to set the hreflang attribute for a multilingual FAQPage Schema?

When a website has multilingual versions of FAQ pages, the hreflang attribute must be correctly set in the FAQPage Schema to help search engines identify the correspondence between different language/region versions. Typically, after the "@context" and "@type" fields in the Schema, add "alternateName" to describe the localized name, and define the URLs and language/region codes of each version through "sameAs" or a dedicated hreflang array. Specific steps: 1. Confirm the URLs of each language version: Absolute URLs must be used (e.g., https://example.com/en/faq, https://example.com/fr/faq). 2. Add the hreflang field in the Schema: List all versions in an array format as [{"@type": "WebPage", "url": "URL", "inLanguage": "language code-region code"}], such as "inLanguage": "en-US" or "fr-FR". 3. Include self-referencing hreflang: The Schema of each version must include its own URL and language information to ensure complete correspondence. After completing the setup, it is recommended to add the hreflang attribute in the <link> tag in the HTML head synchronously to form double verification. You can use Google Search Console's URL Inspection tool to confirm whether the attribute is correctly recognized, ensuring cross-region visibility of multilingual FAQ content.
