Sites are built around "Levels" with "Categories" organizing the content. Categories maybe includes in "Menus". You may also use layouts that automatically layout structured contextual menus for the current level and even category layout can be controlled extensively so that related content is clearly linked on the screen so that the user doesn't have to hunt for more information.
