Although it is not mandatory to be included, you should specify Google product category whenever you can, as it affect how Google identify the right interest groups for you.
The default token Mapped Google category will be suffix in most cases, as it takes the Shopify product categorization data, and magically maps it across to Google equivalent.
You can use the rule-based setting to set Google product categories for the relevant products. Please click here to see an example.
Product type is generally used to categorize your products inside Google Merchant Center. For example, you might run a campaign on your product type "Shoes" and have another campaign for your "Shirts" product type. Keep in mind what products that have been included in the group when you set this parameter. You can also rely on the {product_type} token to pull in the product type field of the product.
You also specify the values for the identifier fields, GTIN , brand and MPN . Google has specific requirements for the identifiers, and the app will automatically set the right value for identifer_exists flag depending on your identifier availability.
There are 5 options for this value, falling in 2 groups:
Let the app decide the value for each item
Auto (default): The app automatically sets appropriate value for an item, based on the presence of GTIN, brand and MPN. If none of the identification is available, the app will skip the identifier exists, effectively leaving Google to decide if it is happy with the absence of the identification. Products with identifications will have the value set to Yes.
Custom products. Same as Auto, except for when none of the identification is available, the app specifically sets identifier exists to No, effectively tells Google that the items without identification are all "custom products" that should not have identification. Products with identifications will have the value set to Yes.
Force a value for all items
Skip: Don't submit a value for identifier exists, effectively leaving Google to decide if it is happy with the absence of the identification.
Yes
No
