Product requirements for publishing

The most important part of publishing your products to Google Merchant Center is making sure that they have the data that Google requires. If your products do not have the right data, Google will return errors and will not publish your products successfully.

Note

Google has specific requirements for products that have Apparel & Accessories, Media, or Book set as the Google Product Category. To learn more about these requirements, read Shopify's guides on Apparel & Accessory specific requirements, Media specific requirements, and Book specific requirements.

Google Product Category

Google requires every product (even custom products) to have a Google Product Category. If you are unsure of which category to choose for your products, read Google's guide to product categories for more information.

To set a Google Product Category:

  1. Go to a Product page in the Google Shopping app.

  2. Scroll down to the Google Product Category section.

  3. Find a category that suits your product in the dropdown menu:

Unique product identifiers

Unless you are selling custom products, Google requires you to have one of the following unique product identifiers for each of your products:

Setting these identifiers lets Google match your product with similar products inside of Google Shopping. If these identifiers are not set accurately, Google will not publish your products and your account could be suspended.

You can read more about Google unique product identifiers.

GTIN (Global Trade Item Number)

GTINs are set by editing the Barcode field on each product's variant. A GTIN can be any of the following:

GTIN Name Format
UPC Universal Product Code 12-digit number
EAN International Article Number 13-digit number
JAN Japanese Article Number 13-digit number
ISBN International Standard Book Number 10- or 13-digit number
