What this checker reviews

Product name, image, description, SKU, brand, identifiers, offer price, currency and availability. Missing identifiers require a review of the real product. Never invent a GTIN or use an internal SKU as a manufacturer identifier.

How to interpret results

A detected field can still contain an incorrect value. This check reads the server response and cannot see markup added only after browser scripts run. It does not verify search eligibility, a private product feed or merchant account settings.
