In one sentence
FAQPage Schema is the Schema.org schema used for FAQ (frequently asked questions) pages. It is the way to explicitly tell AI "this is a question and an answer" for Q&A-format information.
What does this look like in practice?
For example, suppose a health food company's FAQ page contains the question "What is the recommended daily intake of vitamin C?"
In plain HTML, the AI sees only "text." But with FAQPage Schema:
{
"@type": "FAQPage",
"mainEntity": [{
"@type": "Question",
"name": "What is the recommended daily intake of vitamin C?",
"acceptedAnswer": {
"@type": "Answer",
"text": "100 mg is recommended for adults (Japan Ministry of Health, Labour and Welfare standard)."
}
}]
}
