UI Design for the WWW
Creating Effective Sites and Pages
Why Web Site Design Matters




Tests of time to complete shopping tasks at several
major on-line stores - number of clicks varied from 8
to 50; high abandonment rate on poor sites
Jakob Nielsen review of comparative tests on web
sites - average 68% difference in task completion
times
Nielsen finds 135% improvement from redesign
effort
see http://www.useit.com/alertbox/20040119.html
Developing a Site
1. Identify objectives
2. Generate content - typically a topics list
3. Logically organize content - clusters
4. Provide structure to clusters
5. Transform content to pages with graphic design
6. Test and iterate
So what else is new????
Page/Site Goals
• Convey information/access • Convey image or impression
employees, shareholders, customers • Meet people
colleagues, public
• Raise money/donations
• Sell products
• Entertain an audience
• Advertise/market service
• Promote myself
• Recruit
• Teach people about a topic
• Announce, survey
• Get famous
• Nurture communities
• Tell a story
•Search: promote ease and speed
•Browse: without a goal, attractiveness trumps efficiency

users want instant gratification,
and reading is 25% slower on screen than on paper
People tend to skim web pages, just read headers,
highlights, selected paragraphs

Use hypertext to split-up information
People often won’t scroll or read
Use less text

Reflect the content
Simple sentences -- no hype or advertising
Use EMBEDDED LINKS to help visitors find more

Make sure vital content is “above the fold”
Place real content on home page
How much graphics do you use?
If links are in images, have parallel text labels near
page bottom
Home Page Design Has Evolved


From graphics-rich with few links – mostly to
top-level pages of major subsections
To link-rich pages that give access to real
content in one click, plus have some content

Structure of Pages - Templates

Success of link depends on

How well user can predict where link will lead
How well user can differentiate one link from other
nearby ones
Useful content at other end of link
Link Wording

Beware the famous “here”
Click here to learn about my BMW Z3
vs.
I drive fast in my BMW Z3

When a link will take someone a good distance, use
word “jump”

Bad Design Bugaboos
All capitals text
Scrolling sideways
Teeny, tiny text size, especially in italics
Dead links
Telling the user how to set the browser
Poor contrast in text-to-background color
Large typeface (one without impact and contrast)
Animations that don’t stop
Things that look like buttons but aren’t
“Under construction” notices
Neglecting ALT tags for images
Not denoting image sizes
Do-nothing home page
Changing color for the heck of it
Lack of mail to/feedback throughout site
Sites requiring advanced browser or plug in
Jeff Johnson’s Web Bloopers
Chapter 1 – Content Bloopers
1. Home page identity crisis. Home page doesn’t
clearly identify organization or its purpose.
2. Confusing classifications. Content categories
seem arbitrary or nonsensical.
3. Unhelpful descriptions. Content descriptions
do not support choosing among items.
4. Conflicting content. Information in different
parts of site disagrees.
5. Outdated content. Content on site is out-ofdate, but not clearly marked as archival.
6. Missing or useless content. Information users
need to accomplish goals is missing.
7. Unfinished content. Blatantly incomplete
areas of site.
Chapter 2 – Task-Support Bloopers
8. Redundant requests. Asking users for the
same data repeatedly.
9. Requiring unneeded data. Making users
provide non-essential information.
10. Pointless choice. Offering or requiring
meaningless choices.
11. Omitting important options. Choice excludes
options some users need.
12. Clueless back-end. Back-end lacks "common
sense" data needed to support user tasks.
13. Dead-end path: Now you tell me! Allowing
users to go down a path towards a goal before
telling them it is unavailable.
14. Agonizing task-flow. Accomplishing tasks
requires many unnecessary, distracting steps.
Jeff Johnson’s Web Bloopers
Chapter 3 – Navigation Bloopers
15. Site reflects organization chart. Site structure
reflects organization’s structure or history.
16. Numerous navigation schemes. Many ways
to navigate, but no clear guidance.
17. Deceptive duplicate links. Making users think:
"Do those go to the same place?".
18. Not linking directly. Specific-looking links that
go to generic pages or home pages.
19. Lost in space: Current page not indicated.
Page doesn’t clearly show where user is.
20. The circle game: Active link to here. Page
has active link to itself.
21. Missing links: It’s BACK or nothing. Page
provides no navigation links.
Chapter 4 – Form Bloopers
22. Making people type. Using a text field for a
choice setting.
23. Intolerant data fields. Text field is too picky
about how data must be typed.
24. No defaults. Controls and form fields with no
default value.
25. Faulty defaults. Controls and form fields with
the wrong default value.
26. Compulsory clicking: No default text input
focus. Users can’t just start typing.
27. Lame label placement. Labels mis-aligned
with, or too far from, data fields.
28. Checkboxes or radiobuttons? Checkboxes
misused as radiobuttons, or vice-versa.
29. Looks editable but isn’t. Using standard datainput controls for display-only data.
30. Mysterious controls. Operation of controls is
unclear due to poor labeling, poor layout, or
uniqueness of controls.
Jeff Johnson’s Web Bloopers
Chapter 5 – Search Bloopers
31. Baffling search controls. Search options require
knowledge of computer or industry-insider
concepts.
32. Dueling search controls. Competing search
boxes on page, with no guidance.
33. Hits look alike. List of found items cannot be easily
distinguished by scanning.
34. Duplicate hits. List of found items contains
duplicates.
35. Search myopia: Missing relevant items. Items
that should be found are not.
36. Needle in a haystack: Piles of irrelevant hits.
Many items don’t match search criteria.
37. Hits sorted uselessly. Sort-order of found items
doesn’t support user tasks.
38. Crazy search behavior. Modifying search criteria
yields unexpected results.
39. Search-terms not shown. Not showing what
search terms produced these results.
40. Number of hits not revealed. Not showing how
many items were found.
Chapter 6 – Text & Writing Bloopers
41. Too much text. Overly-verbose instructions,
messages, or link-labels.
42. Speaking Geek. Computer jargon in error
messages, commands, or instructions.
43. Calling site visitors "user" . Using the
computer jargon term "user" on a website.
44. Insider jargon. Using the vocabulary of
industry experts, rather than that of users.
45. Variable vocabulary: Different words for the
same thing. Inconsistent terms.
46. Inconsistent style. Text on site does not follow
consistent style rules.
47. Typos and grammos: Sloppy writing. Failing
to check and fix text before going live.
Jeff Johnson’s Web Bloopers
Chapter 7 – Link Appearance Bloopers
48. Links don’t look like links. Links not marked
well enough, so users miss them.
49. Non-links look like links. Non-link text is
underlined; or non-link graphics look clickable.
50. Bizarre buttons: Click target smaller than it
seems. Entire boxed area surrounding link label
looks like part of button, but only label accepts
clicks.
51. Wrapped links: How many? Multi-line text
links.
52. "Click here": Burying links in text. Important
navigation links embedded in prose.
53. Been there, done that? Can’t tell. Traversed
links not clearly marked.
Chapter 8 – Graphic Design & Layout Bloopers
54. Tiny text. Text typeface too small for many
users to read.
55. Camouflaged text. Text contrasts poorly with
background.
56. Centering everything. Centering prose text,
bullet items, controls, or data fields.
57. Unobtrusive error messages. Error messages
easy to miss due to poor placement.
58. Shades of beige: color differences too
subtle. Relying on small color differences to
convey important meaning.
59. Dead or Alive? Active buttons look inactive.
Buttons appear "grayed out" but aren’t.
60. Terrible tabs. Navigation tabs don’t look and
act enough like real tabs.
