A product category is a naming convention that describes the type of item you sell. Providing product category information can help customers browse and search for your store's products. It can increase your store's discoverability and help improve your ad performance. Product categories help determine how much your customer needs to pay in taxes or if a product is eligible for a custom return policy. At the same time, product categories help you to classify and manage products with different attributes. The product categories provided by Shoplazza are divided into two types: custom categories and Google categories. You can manage products by creating custom categories, or you can also add product categories from Google categories directly.
