A specific type of Schema.org markup that labels question-and-answer content so search engines and AI systems can extract Q&A pairs verbatim into their results.
FAQ schema (FAQPage with nested Question/Answer) is one of the highest-leverage AEO investments because answer engines literally extract these pairs. A well-marked FAQ block on a pricing page can land your brand in ChatGPT's answer for “how much does X cost.”
Best practices: keep questions in natural conversational language, keep answers under 250 words, mark up the FAQ that actually appears on the page (Google penalizes hidden FAQ schema), and put the FAQ on commercially-relevant pages (pricing, product, comparison) not just a generic /faq page.
An HR software company marks up the FAQ on their HRIS comparison page with FAQPage schema. Perplexity begins citing their 'What is an HRIS?' answer verbatim — the answer appears word-for-word in AI responses across multiple engines.
