The taxonomy, or often called navigation, of a site is probably one of the most important pieces of an online commerce system. Being able to narrow down to a product through search and a faceted navigation system is very important to the site visitor. One example of this is being able to describe a product through facets (or attributes in some systems). Many times eCommerce systems provide attributes that can be tied to a product and these attributes ultimately drive the faceted navigation system. A brand would use these attributes to aid the shopper in finding the right product. Sometimes a brand may want to have a hierarchy of facets like colors. You may want to promote your colors through high level categories and then drill down to specific colors so your faceted navigation might look like this:
The facets to the left could be a single facet in the system named “Color”. But because we could assign multiple values to a single product, the product could potentially show up under “Blues” and possibly “Periwinkle, Powder Blue, or Baby Blue”. This lets the shopper navigate to a single product in multiple ways. You might want to consider offering multiple options for your products to make finding them easier. I mean, who doesn’t want to click on Periwinkle?
