What each Merchant Center error means on Shopify, and how to fix it.
Why does Merchant Center say "Limited performance due to missing value [gtin]" for my Shopify products?
Google shows this when a Shopify product has no barcode. It is a warning, not a disapproval. What GTIN is, when you need one, and how to add it — or safely skip it.
Why does Google Merchant Center say my Shopify products are missing a brand?
Google needs a brand for most products. Shopify sends the Vendor field as brand, so a blank or placeholder vendor is the usual cause. What to enter, including for your own products.
Why is Google Merchant Center rejecting my Shopify products for a missing image?
A Shopify product with no image can't be listed on Google Shopping or Meta. How to find these products, what Google expects of an image, and what to do when an image exists but Google says it wasn't processed.
My Shopify variant has several barcodes. Which one does Google get?
A Shopify variant can now hold up to 20 barcodes. Sales channels read the first one, so that is the GTIN Google receives. How to check the order and what belongs in first place.
What happens on Google and Meta when a Shopify product has no description?
Google requires a description, warns when it is missing and may show the product less. Meta may not accept the product at all. What a description must contain and how to add one in Shopify.
Do I need to set a product category in Shopify for Google Shopping?
Google assigns every product a category on its own, so the field is optional. When setting it yourself matters, what "Uncategorized" means, and where the field is in Shopify.
Why does Merchant Center say my Shopify product has a mismatched price?
Google disapproves a product when the price in your product data differs from the price on the product page. The causes Google lists, where to look on a Shopify store, and how to get the product checked again.
Why does Merchant Center say my Shopify product page is unavailable?
Google stops showing a product when it cannot reach the product's landing page. The errors Google lists, where each one comes from on a Shopify store, and how to ask for a new check.
Why does Merchant Center say my Shopify product is missing size, color, gender or age group?
Google asks for age group, gender and color on apparel, and size on clothing and shoes. Which products and countries the rule covers, the values Google accepts, and where to add them on a Shopify store.
Why does Merchant Center say my Shopify products are missing shipping costs?
Google does not show a product until it has a shipping cost. Why a Shopify store's rates can fail to reach Merchant Center, and the two places to set them.
