What this is
Product data is the full set of product details AI shopping systems use to understand and compare what you sell.
What to include
At minimum, prioritize product name, description, brand, SKU or GTIN, price, availability, images, variants, product URL, shipping information, and policy context.
How to verify
Pick your most important products and compare the product admin, live page, structured data, and feed. The same facts should appear consistently across all of them.
