Full Answer
WooCommerce generates a minimal Product JSON-LD block: name, description, price, and an in-stock or out-of-stock availability value. That's technically valid schema, but AI shopping engines treat it as a skeleton — not enough to act on.
The first gap is identity. Without brand, GTIN, MPN, or SKU in the markup, AI engines can't verify which product you're selling or match it against a buyer's query. A search for "Canon EOS R6 II body" needs those identifiers to confirm your listing is the real product, not a generic description.
The second gap is trust signals. AI engines weigh aggregateRating and reviewCount heavily when deciding which merchant to cite. WooCommerce has a review system built in, but the default schema doesn't expose those ratings as structured data — so AI engines see a product with no social proof.
The third gap is commercial detail. Properties like shippingDetails, hasMerchantReturnPolicy, and itemCondition tell AI engines whether your listing is current, deliverable, and returnable. Google's structured data documentation lists these as recommended for merchant listings — AI engines treat the same fields as required (Google Search Central, 2026).
