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.
For a product to be visible in your store, it must be assigned to at least one category. Each
category can have a dedicated landing page with an image, static block, a description, and list
of products. You can also create special designs for category pages that become active for a
specific period of time such as for a holiday season or promotion.
