Validate the Product and Offer structured data on any product page. See whether you have the price, availability, return policy, shipping, GTIN, brand and reviews that Google needs for product rich results, star ratings and free Merchant listings.
What does a product need to show up in Google Shopping?
A Product schema with name and image at minimum, then an Offer with price, priceCurrency and availability. For free Merchant listings you also need a product identifier (GTIN, MPN or SKU) and, ideally, hasMerchantReturnPolicy and shippingDetails.
How do I get star ratings on my product?
Add aggregateRating (or individual review markup) to the Product schema. This tool tells you whether it's present — Google shows the stars in results when it is and the reviews are genuine.
What are hasMerchantReturnPolicy and shippingDetails?
Structured data on the Offer that lets Google show returns and delivery/shipping annotations directly in search and Shopping. They're a strong trust signal for e-commerce and this tool flags them if missing.
Does it handle product variants?
Yes — if the page uses ProductGroup, it checks for hasVariant and variesBy (the axes like size and color) so Google understands your variant structure.
