Information architecture determines the overall structure of a web site – the flow from home page to sub-level pages to thank you pages. Usability is a large part of information architecture. Does the visitor feel oriented? Do visitors know where to go for the information or functionality they want? Is the navigation intuitive? Is the user interface empowering and informative? The nomenclature and organization of that information, the ability to sort through and customize it, will determine the success of the visitor’s experience. Like any good sales pitch, it’s anticipating the question before it is asked and presenting a thoughtful answer.
The major content categories should be easy to grasp and they should align with specific target audiences. It is also important to surround any individual document or issue with related materials. This approach helps pull users into the material and establishes broader relationship to your brand, even if they originally pursue very specific information.
The information architecture will also form the basis of the guidelines for content length and layering. Information should be presented in a layered manner, allowing users to get a solid overview and then choose to drill down to more detail if they are interested. Supporting information to the primary text on any page should be presented as second reads on the page, drawing users to pertinent facts and recognizing the propensity of Web users to skim as they read.
Information architecture for the web is much like the design of a library or supermarket. The idea is to provide paths to information by showing relationships. Of course, web sites do not consist solely of linear relationships. Pathways through sites can be varied and few users will take the exact same path. Navigating is subjective, based on someone’s own preferences, interests and experience. Sites must be designed with a full understanding of the medium. Vertical pathways through the information must be straightforward and reliable, while lateral pathways should surface related information elsewhere on the site. Finding a balance between the way information “wants” to be organized and how the users want to find it is the key to successful information architecture. Once the relationship between the major content groups, the target audiences and the audiences’ expectations are established, the site mapping can begin.
