6. Navigation Design
Site-level navigation: making it easy
for the user to get around the site
Page-level navigation: making it easy
for the user to find things on a page

Navigation
Choosing a path through the web
site’s information space
Goals:
Let user know where he is
Give user confidence in knowing where
he is going next

Navigation: Connections
Good navigation builds on good content
organization (Chapter 4)
Choose a navigation system that reflects the
content’s organizational structure
Visual design (Chapter5) and navigation
design are interrelated
Choose visual navigation elements that build
context for a user

Navigation: Connections
A Navigational System is a visual
representation of an organizational
structure
Navigation Bar: collection of links grouped
together on a page
Site-level navigation vs. Page-level
Navigation
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Three types of navigation systems
Hierarchical
Derived from hierarchical organization
Ad hoc
Hyperlinks
Database
Search engines
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Rare to use only one
Most websites build on a judicious
combination of these three, with
one dominant theme
Hierarchical plus hyperlinks (ad hoc)
is most common
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
A pure hierarchy is rare
We add links to facilitate moving around the
hierarchy without going all the way to the top;
note extra links at bottom level

Global navigation
For a small site, it may be possible to show
the major links on every page

Showing more levels in the hierarchy
Drop-downs or pull-outs can show the
next level

Other items
Breadcrumbs: a sequence of links
showing user how he got to current
location
Subsite: a collection of pages that
share a common navigation system,
perhaps different from the website as
a whole
Chapter 6: Navigation

Breadcrumbs show user “This is
where you are how you got here”

Ad hoc links are very common
(created for one specific purpose)
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
The most familiar example of
database navigation: Google

Building Context
Helping the user to understand where
he is and where is can go in the web
site
Navigation can be used to build
context

Labels vs. Graphics
Graphical representations are nice but
slower to download
Should always include label with
graphic
Be careful in selecting both labels and
graphics
Consider conventions
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Be careful with metaphors: what
do these mean?
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Intended meanings. Moral: add
words, too!
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
So add words!
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Some Standard Conventions
Home: the main entry point of a Web site,
generally containing the top-level links to
the site
Search: find related pages by supplying a
word or a phrase
About Us: information about the company
that created the site
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Some Standard Conventions
Shop: browse for merchandise
Check Out: supply shipping and billing
information, complete transaction
Contact Us: initiate interactive dialog with
customer representative – phone or email
Consistency + Conventions

Menus
List of possible links
Usually in drop-down form
Provides many more options without
clutter
Disadvantages
Not all options are visible
User must act to activate a menu
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Menus pack in a lot of informationNote the dropdown from Software
Chapter 6: Navigation

Site maps
Graphical representation of the site
Textual
For a big site, must be selective
Graphical
A site map is no substitute for good
navigation
Trend away from site maps

Frames
Frame: an area of a browser window that stays
visible as the user moves from page to page
Simple way to provide global navigation: scrolls
But hogs screen real estate: you can’t do
anything else with that space
May not print
Hard (impossible?) to bookmark
Used much less often than formerly
See Jakob Nielsen, “Why Frames “Suck (Most of
the Time)”
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Built-in browser services
Take advantage of these
History of pages visited
Back & Forward Buttons
Color coding of links
Unvisited vs. Visited vs. Active
Don’t mess with built in conventions
e.g. Blue is an unvisited link.

Page-level navigation aids
Remember proximity, alignment, consistency:
make the layout obvious
Make size of text box appropriate to amount of
data
Show which fields are required with * or Required
Use error messages
Make button placement consistent: before or after
its associated text
Chapter 6: Navigation
Copyright © 2004 by Prentice Hall
Make error reports clear
Explicitly state the problem
Perhaps change the color of the offending box
Show as many errors as possible on one page;
don’t make user correct one error per attempt to
send the data
Don’t make user re-enter correct data
Sounds obvious, huh? Then why are so many
forms terrible?
Sales are lost at this point, in big bad quantities

Summary
Effective navigation is a combination
of good content organization and good
visual organization
The main navigational system is
hierarchical, with hyperlinks added
You can learn from all the bad sites
you’ve suffered with
