Abstract:

What I've called structure in this series actually has various other names, the most familiar of which are probably 'hierarchy' or 'information architecture.' Whichever word you use, structure encapsulates the relationships between the components of a site that visitors will use to navigate to the information they seek. Structure is simple enough to define, but can be devilishly tricky to create. A successful site structure must create what psychologists refer to as a schema: A mental model that visitors can use to understand where you've hidden the content.
