Category

The ‘Category’ dimension reports the product category of the hit. It is useful for implementations that use the products variable and want to see metrics around product category, such as top sellers or most viewed. This dimension can intentionally be blank if you don’t have any products on your site.

Populate this dimension with data

This dimension references the product category in the products variable, which is everything before the first semicolon (;).

Dimension items

Since this variable is based on a custom string in your implementation, your organization determines what the dimension items are. Adobe recommends that you group individual products into meaningful categories, using both the ‘Product’ and ‘Category’ dimensions.
