TL;DR — Product schema is the schema.org markup that describes an item for sale in machine-readable form — name, image, description, brand, identifiers like GTIN and SKU, and an Offer carrying price, currency, and availability. It powers rich results (price and star ratings in the SERP), feeds Google Shopping's understanding of product pages, and supplies the structured facts AI shopping surfaces need when assembling recommendations. For eCommerce it is the single highest-value schema type: a catalog without Product markup forces every engine to guess at exactly the attributes buyers filter on.
Definition & scope
Accuracy is enforced: engines compare marked-up price and availability against the rendered page, and mismatches forfeit rich results. Markup should be generated from the same source of truth as the visible page — the platform's catalog data — never hand-maintained.
As agentic commerce grows, Product schema doubles as the machine-readable storefront: an AI agent evaluating whether your product fits a user's request reads these fields long before any human sees the page.
