Does adding JSON-LD schema really increase inclusion in AI Overviews?

Yes, pages with FAQPage, HowTo, and Organization schema appear 28-42 % more often in AI Overviews tests because the markup gives LLMs safe, machine-readable facts. (Source: Lumar)

Implementation tips

• Keep JSON-LD inline (not GTM) so crawlers fetch it.
• Use explicit sameAs links to reinforce brand entity.
• Validate with Rich Results and Perplexity’s open-schema checker.
