What the error means
Brand is required for most categories. Products submitted without one are rejected.
Why Google rejects it
Brand is part of how Google identifies a product and matches it against the same item sold elsewhere.
How to fix it
- Set the vendor field to the manufacturer brand, not your shop name — unless you actually manufacture it.
- For genuinely unbranded products, some categories accept the manufacturer or a generic identifier instead.
- Keep the brand consistent across variants of the same product.
