To help visitors find what they are looking for easily, clearly and quickly, it is important that web pages and customer routes are designed so that the visitor understands and can use them intuitively.

Therefore, help the visitor create a 'mental model' of the website:

• Where am I now? 
  What is this site, what is this page, how does this page fit in?
• What can I do here? 
  Does this fit with what I came for?
• Where can I go? If not, how can I complete my task?
  In this the following articles attempt to provide insight into when and in what form, navigation should be shown to a visitor:
