Google (May 2026): "Structured data isn't required for generative AI search"

Quote (verbatim from Google Search Central): "Structured data isn't required for generative AI search, and there's no special schema.org markup you need to add. However, it's a good idea to continue using it as part of your overall SEO strategy."

Confidence: Verified (primary).

Important nuance: "Not required" ≠ "not useful." The same document also recommends continuing to use structured data. Pair with Ahrefs (April 2026): adding schema to 1,885 pages produced no AI-citation lift; AI Overviews showed -4.6% (no controlled lift on already-indexed pages) and Schanbacher (SSRN 2025): FAQPage and Product schema strongly predict ChatGPT visibility (single-domain peer-reviewed) (10× acquisition lift in a peer-reviewed real-estate domain). The honest position: schema is foundation-grade hygiene, not a citation hack. See RULE: Always ship schema as hygiene. Never expect it alone to move AI citations..
