Your website can have a lot of content for many different users. They need to be able to find what they're looking for and navigate to related items.
Menus
Menus let you define how your site's content can be accessed.
You can organize your content in a hierarchy, allowing easy navigation.
An effective menu needs to consider how the user sees the site, and the structure has to make sense to them.
Taxonomies
Taxonomies can be used to tag content to define categories and other properties that can be used to find content.
Paths
Note the urls you have on your site. Good site structure aligns url paths with the content organization to indicate which section you are in.
