Product categories are a logical way to organize your e-commerce products. This allows site visitors to quickly locate items they want to purchase. The Kentico
CMS E-Commerce module allows products to appear in multiple product categories based on a link. When creating a link to an existing product document, a product SKU is not directly tied to the link. The link represents an image of the existing product document. This process allows a product to exist independently of the link. The benefit of the linking process is that it allows the same product with the same SKU to appear in multiple product categories.
