The term navigation refers to the methods shoppers use to move from page to page
throughout your store. The main menu, or top navigation of your store is actually a list
of category links. The category structure of your catalog is the main way people find
products in your catalog. You will also find categories in the breadcrumb trail that runs
across the top of most pages, and in the “layered navigation” that appears on the left
side of some two- or three-column pages. These are all examples of how categories can
be used to navigate throughout your store.
