How do I set up Product Categories in Smart Commissions?
Within our Smart Commissions tool is the option to apply commission to Product Categories (i.e Google Product Categories).
This value will come from the Product Feed uploaded within your advertiser program, for products in the google_product_category column.
Please note, as per Webgains Product Feed requirements, the feed must adhere to Google Product Category specifications. For more information please view: https://support.google.com/merchants/answer/6324436?hl=en&sjid=4002122127875851262-EU
When creating your Smart Commission scheme, simply select ‘Apply Products’ > ‘Apply to Product Categories’. Then, select the desired categories within the dropdown (results generated as per the product feed).

Smart Commission Creation: Apply to Products
Any products that track matching this category (and any other rules applied to the commission scheme, according to priority order) will apply this Commission.
