Why is my dropshipping product feed disapproved for 'Missing value [gtin]' in Google Merchant Center?

Google Merchant Center requires a valid Global Trade Item Number (UPC, EAN, JAN, or ISBN) for all manufactured retail products. If you are dropshipping private-label, unbranded, or custom print-on-demand items that do not have a GS1 barcode, you must set the [identifier_exists] attribute to 'no' (or 'false') and omit both [gtin] and [mpn]. Leaving [identifier_exists] as 'yes' while submitting a blank GTIN triggers an automatic item disapproval.

How should price and shipping weight attributes be formatted in an XML or CSV product feed?

Google Merchant Center and Meta Catalogs require ISO 4217 currency codes appended directly to numeric prices (for example, '29.99 USD' rather than '$29.99' or '29.99'). Similarly, [shipping_weight] must include a space and a valid unit suffix ('lb', 'oz', 'kg', or 'g', such as '1.5 lb' or '680 g'). Submitting bare numbers without unit suffixes causes feed parser rejections and carrier rate calculation failures.

What causes 'Invalid image_link' or 'Promotional overlay on image' feed rejections?

Product feed image URLs must use HTTPS protocol, link directly to a supported raster image file (.jpg, .png, .webp, .gif), and measure at least 100x100 pixels (250x250 pixels minimum for apparel). Additionally, product titles and images cannot contain promotional text such as 'Free Shipping', '50% Off Sale', 'Best Seller', or excessive ALL-CAPS words, which trigger automated policy demotions.

Frequently Asked Questions

How do I fix "Limited performance due to missing identifiers [gtin, mpn, brand]"?

When selling branded or manufacturer-distributed products, Google requires both [brand] and a valid GS1 [gtin] barcode. If your dropshipping supplier does not provide UPC/EAN barcodes and the item is unbranded or custom-manufactured, you must explicitly add <g:identifier_exists>no</g:identifier_exists> (or set the identifier_exists CSV column to no). Never fabricate fake GTIN numbers, as Google cross-references prefixes against the official GS1 database and suspends accounts for counterfeit identifiers.

Why are my products rejected for "Mismatched value (page crawl) [price]"?

Google's automated StoreBot crawls your product landing pages daily and compares the visible price and JSON-LD Product schema markup against the [price] submitted in your XML/CSV feed. If your feed lists 29.99 USD without currency formatting, or if a dynamic currency converter plugin changes the price on the landing page, Google disapproves the item. Always format feed prices as XX.XX USD and ensure your theme's structured data matches the default variant price.

What attributes are mandatory for Apparel & Accessories feeds?

Any item categorized under Google Product Category 166 (Apparel & Accessories) requires four additional demographic and variant attributes: [color], [size], [gender] (male, female, or unisex), and [age_group] (adult, kids, toddler, infant, or newborn). Furthermore, all size/color variants of the same garment must share an identical [item_group_id].
