Product Schema

Product schema is the specific structured-data type for product pages, defined by schema.org and used by Google, Bing and AI tools to understand what's for sale. It's the form every product page should fill in. The fields that matter most for an online store: name, image, description, brand, an offer (price, currency, availability, and the URL to buy), aggregateRating and review if you have reviews, and at least one identifier — GTIN, MPN or SKU — so the product can be matched to the same item elsewhere.

Most platforms emit a basic version automatically. The problems are in the details: themes that override it and break it, apps that inject a second conflicting copy, and — most often — fields left blank because nobody filled the brand or GTIN in the product data. Blank fields read as unknown, and an unknown product is one a machine can't confidently recommend or an agent can't confidently buy. Google's Rich Results Test reports exactly which fields are missing on a given page, and Search Console's Products report shows the same site-wide. Filling the product data in your platform is usually the whole fix; CataSEO writes the schema and the description together so they can't drift apart.
