At the product tags page you can manage your product tags. It allows you to create, modify and delete product tags.
Product tags function as groups for products. Usually you would group a product not only by it’s general type but by key features too.
e.g.: If you sell computers you might want a product to belong to several groups like “Intel”, “Laptop” and “Windows”. Product tags allow you to create and assign these groups to products.
Product tags are similar to product types, but differ in a key feature. While you can only have a single type per product, you can have multiple tags per product.
e.g.: The aforementioned computer product might have the product type “Laptop”, but since you still want several subgroups for that product, you are using the product tags “Intel”, “Laptop” and “Windows” for that product.
Product tags are assigned to products at the product details page.
