Question Heading
An H2 or H3 phrased as a question that matches user queries.
A question heading is an H2 or H3 written in interrogative form — "What is X?", "How does X work?", "Why does X matter?" — rather than as a noun phrase or label.
Question headings align your content structure with how people actually query AI engines. They also signal to crawlers that the paragraph below is an answer, which improves extractability.
