5.2b Define navigation

Guideline

It is important that your site is easy to navigate. Consistency and predictability are the key. A user should be able to drill down for information and find their way back through the levels easily and intuitively. Disorientating your users is guaranteed to send them away from your site.

Checklist... Navigation

  • Are the deepest levels of information available within 2-3 mouse clicks from the home page?
  • Can you drill down through the site and find your way back to the original page easily?
  • Do you have breadcrumbs? This navigational technique displays the hierarchy of all the Web pages leading from the home page to the currently viewed page. The pages are linked for easy backwards navigation.
  • Does each page behave in the same way? If not, is there a good reason for that?

Think:

    1. Where am I?
    2. Where have I been?
    3. Where can I go next?
    4. Where is the home page?

Page layout

Page layout (i.e. how the contents of a Web page are arranged) is a key aspect of the user's navigational experience. Ideally, the structure of a Web page should not change dramatically as users click around the Web site: what happened on one page should happen in the same way on other pages. Consistency is one of the main defining principles for a successful Web site.

If you click around FAO's Web sites, you will note that the page layout of most sites is based on a design that has the area beneath the banner split into two or three columns. Each column should have a specific role and that role should be consistent.

  • Left column: the left column is normally reserved for navigation of the internal pages of the Web site and normally lists Web pages in a menu style. Clicking on a Web page usually changes the information in the central column. Try to avoid using the left column to list links to external documents, other Web sites or additional information that is not part of the main Web site. Use the central or right-hand column to list this type of information.
  • Central column: the central column normally contains text and in some cases additional materials such as photos, links etc. Try to avoid stuffing the text with too many hyperlinks as this can become disorientating for users.
  • Right column: the right column is commonly used to list additional information that supports the written content of the central column. See example below:


Navigation schemes

FAO Web sites use a range of navigation schemes. Menus listing are displayed in a number of ways depending on the system being used and the type of information being displayed. There are currently two principle navigation schemes:

  1. top-tab menu navigation; and
  2. side-menu navigation.

Remember... Keep it consistent!

The navigation system should be in the same place on every page and have the same format. Visitors will become confused and frustrated if links and menus appear and disappear unpredictably.

Top tab menu

At FAO there are numerous Web sites that use top tab menu navigation as the principal method for moving around the Web site. Clicking on one of the top tabs or content categories, takes the user to a new menu.

Examples:

The International Plant Protection Convention Web site

Side-menu navigation

Side-menu navigation has traditionally been used on the Web since the Internet first became popular a decade ago. This type of site navigation is used throughout FAO.
