A site's hierarchical structure is like the family tree of a website or digital platform. It organizes content into a top-down approach, starting with general categories that branch into more specific subcategories.

Imagine a digital library's homepage showing main sections like "Fiction" or "Non-Fiction." Clicking on "Fiction" might lead you to subcategories like "Mystery," "Romance," or "Fantasy." This pyramid structure guides users through layers of content, helping them drill down to the information they need. It's a clean, intuitive way to navigate, making complex sites more user-friendly.
