How does the product vendor filtering work?
Shopify lets you assign a product vendor to each product. This can be done on the Shopify product editing page:
You can limit the random recommendations displayed to products from the same vendor of the current product by enabling the following option in the Also Bought preferences page, inside Recommendation tuning:
Let's say, for example, that you are viewing a product page whose vendor is 'Nike'. The random recommendations displayed will only be products from 'Nike'.
If you have enabled shopping cart page recommendations, recommendations from all vendors in the shopping cart will be displayed.
For example, if there are two products in your shopping cart, one from ' Nike' and the other from 'Adidas', the recommendations displayed on the shopping cart page will be products from either 'Nike' or 'Adidas'.
Please note, if there are not enough products matching the selected criteria, the recommendations will be automatically completed using random recommendations.
