What types of queries trigger AI Overviews?

AI Overviews primarily appear for: informational queries (how-to, what-is, why questions), complex multi-faceted topics requiring synthesis, comparison queries, educational content, health and wellness questions (with extra scrutiny), financial topics, and technical explanations. They rarely appear for navigational queries, simple factual lookups, or transactional/purchase-intent searches.
