Product schema for stores: mark up only what is visible
Structured data is the same product a shopper sees, written so a parser can read it. It is not a ranking hack.
Emit Product for name, image, and description. Add Offer only when a real price and availability are on the page. Skip AggregateRating without real reviews.
