i) Hierarchical Structure.

The hierarchical structure illustrated in the following is probably the most commonly used information design. It lends itself to larger content collections because the section pages break up and organize the content at different levels throughout the site. Navigation is primarily linear within the content sections.

ii) Web Structure.

Many smaller Web sites follow the Web-type content structure illustrated below which is nonlinear, allowing the user to jump freely to any page from any other page.

iii) Linear Structure.

The linear information structure, illustrated below, guides the user along a straightforward path. This structure lends itself to book-like presentations; once into the content, users can navigate backward or forward.
