How does the product type filtering work?

Shopify lets you assign a product type to each product. This can be done on the Shopify product editing page:

You can limit random recommendations displayed to products of the same type of the current product by enabling the following option in the Recommendation tuning section:

Let's say, for example, that you are viewing a product page whose product type is Shirts. The random recommendations displayed will only be products with the product type Shirts.

If you have enabled shopping cart page recommendations, recommendations of all product types in the shopping cart will be displayed.

For example, if there are two products in your shopping cart, one of type Shirts and the other of type Trousers, the recommendations displayed in the shopping cart page will be products with the type either Shirts or Trousers.

Please note, if there are not enough products matching the selected criteria, the recommendations will be automatically completed using random recommendations.
