How to correctly add multiple Q&A pairs in the FAQPage Schema?

When multiple question-answer pairs need to be added to the FAQPage Schema, it is usually necessary to define an array containing multiple Question-Answer objects in the "mainEntity" property through JSON-LD format to help search engines accurately identify the Q&A content of the page. The specific implementation structure includes: - Basic declaration: The root node must specify "@context": "https://schema.org" and "@type": "FAQPage". - mainEntity array: Each question-answer pair is treated as an array element, and each element contains "@type": "Question" (the question text is defined through the "name" field) and "acceptedAnswer": {"@type": "Answer", "text": "answer content"}. Notes: Format specification: The array must be enclosed in square brackets "[]", and objects are separated by commas to avoid JSON syntax errors. Content correspondence: The question-answer pairs must be consistent with the actual visible content of the page to ensure information matching when search engines crawl. After completion, it is recommended to use Google's Structured Data Testing Tool to verify the code to ensure that multiple question-answer pairs are parsed correctly, which directly helps improve the display of FAQ rich snippets for the page in search results.
