DIRECT ANSWER
Website structure is the underlying organization of pages and content within a website, defining how information is arranged and connected within a broader website development system.
EXPANDED EXPLANATION
It includes hierarchy, relationships between pages, and how content is grouped into categories or sections. Structure determines how easily users can understand a website and how efficiently content can be managed.
While often confused with navigation, structure exists beneath what users see. Navigation reflects structure, but cannot compensate for poor organization.
SYSTEM CONNECTION
Website structure is a component of website architecture. It directly impacts user experience, website maintainability, and how effectively the website supports business goals.
