How does outlining the information architecture of a website help improve the reading experience for site visitors?

Because the web is a multidimensional medium,readers move around in any order they please; there often is no beginning,middle,or end.When organizing a website,you need to anticipate the various paths your readers will want to follow and make sure you provide the right hyperlinks in the right places to help readers explore successfully.Professional website designers use the term "information architecture" to describe the content structure,labeling,and navigational flow of all the parts of a website.In a sense,the information architecture is a three-dimensional outline of the site,showing (1)the vertical hierarchy of pages from the homepage down to the lower level,(2)the horizontal division of pages across the various sections of the site,and (3)the links that tie all these pages together,both internally (between various pages on the site)and externally (between the site and other websites).
