A. IMPORTANCE OF USABILITY

5. Common usability user concerns
o “Where do I start?”
o “Why did they do that? Why did they call it that?
o “Can I click on that?”
o “Those two links seem like they’re the same thing. Are they really?”
o “Why did they put that there?”
o “Words I´m looking for are not there”
o “There’s too much going on. What are the most important things on
this page? “
o “Is that an ad or part of the site?”

6. Common usability user challenges

8. If you include many
choices on said
pages, you’ll make
it harder for your
site visitors and
leads to make a
decision, which can
cause lost
conversions and
unhappy clients!

9. “Satisficing”-Muddling through
What really happens?
Users don’t read, they SCAN
 Don’t really need to read
everything  Read in a hurry
 Users often don’t take the time to
figure out how things work and
make the optimal choices - often
choose the first reasonable option
– satisfice
We’d like to think
users will read our
site from top to
bottom, then make
choices.

Context
UsersContent
On the internet, the
competition is
always just one click
away, so if you
frustrate users
they’ll head
somewhere else.

12. USABILITY
USEREXPERIENCE
Usability means making sure something
works well, and that a person of average
ability or experience can use it for its intended
purpose without getting hopelessly frustrated

B. LAWS OF USABILITY

13. Purpose and Strategy:
 What is the purpose of the webpage? Pages should have a clear visual
hierarchy: Elements should display a logical order, and have relationships
to one another
 A Web page it should be self-evident. Obvious. Self-explanatory.
Content, Navigation, Interaction:
 Relevant pages should never be more than two clicks away, if really
essential to have more, each click should be is a mindless, unambiguous
choice until the goal.
• Don’t lose search: search-dominant users will almost always look for a
search box as they enter a site or breadcrumb navigation path
Steve Krug´s Laws of Usability

14. Steve Krug´s
Laws of Usability
Presentation/User Interface Design:
 Tweak, don’t redesign: Innovate only when you
really have a better idea
 Making everything easier to use for user
 Best solution is removing something, not adding
something
 Focusing on ‘can this be used when it’s done?’
rather than just making it look good.”
 Ideally strategize page based on consumer´s insights
throughout the development cycle

15. Steve Krug´s Laws of Usability
Accessibility
#1. Fix the usability problems that confuse users: broken links, errors in forms,
inadequate on page search results
#2. Apply Image Alt Tags : good for visually impaired users and SEO (increasing
changes coming from Google Images Organic Traffic
#3 Use CSS when appropriate:
• Infinitely greater control of formatting.
• A single change in a style sheet can change the appearance of an entire site
• Consistent among browsers.
• Allow to put content in sequential order in the source file.
• CSS makes it easy to make your text resizable, which is enormously helpful for
low-vision users

16. Steve Krug´s Laws of Usability
Accessibility
#4. Don’t use JavaScript without a good reason.
 Not SEO friendly language
JavaScript loaded parts of a website might not be indexed by Search Engines. Making
sure that search engine bots can see your content, and making sure they can see and
follow your navigation is crucial. Viewing a site as text-only (lynx or elinks) can also
help you identify other content which may be hard for Googlebot to see
• Hurts webpage loading time/ performance:
Webmasters who use AJAX to load multiple parts of their website in separate
requests so that the web browser is tricked into thinking that the website is loaded
after the first request of HTML ,but this will slow down the actual loading of the
website.

17. USABILITY IS
ABOUT THE USER
GETTING THE
TASK DONE
“On the Web, usability is a necessary
condition for survival. If a website is
difficult to use, people leave.”

PRINCIPLES FOR
USABILITY

Visitors to a webpage tend to
interact with it based on
recognized design
principles/heuristics

19. Jakob Nielsen
THE Usabilty Guru
Jakob Nielsen´s
THE 10 UX
PRINCIPLES FOR
USABILITY
•Published by Jakob Nielsen in 1995
•Widely accepted and still holds true today.
•Other variation models exist

20. 1 SHOW SYSTEM STATUS
EXAMPLES:
•Active Menu item, Step wizards, Loading
animations, Progress bars, Cart indicator,
•Password strength (dynamic validation)
•Confirmation messages
•Pagination
•Document opened by same person.
Postlocking
Dynamic breadcrumbs
Second states for
immediate user
feedback (Activeor
On Press/hover)

21. 2 MATCH BETWEEN
SYSTEM AND REAL
WORLD
•Icons, Folder, tabs, radio,Mail badge/
notification, Pagination, Save icon, Gauge
meter, Switch toggle
•Cropping tool behaviour, Trash
•Text> human language
•Categories naming
•WYSIWYG
Tabbehavior
Saveicon
Icons in general
Human Computer
Interaction (HCI)

22. 3 CONTROL AND FREEDOM
Emergency exit!
•CRUD (Create, Read, Update, Delete)
•Quit, cancel, remove, go back
•Skip intro, Read later, update later
•Explore and advanced filters
•Edit plugin/theme
•Search!

23. the menu
burger icon
(use with caution)
Consistent layout
positioning
UI kit as tool box
Do not override established standards
(Radio vs. Checkbox functionality, * required field)
4 CONSISTENCY AND STANDARDS
•Hyperlink underline
•Hierarchy
•Interactive elements buttons
•Navigation standards
•TRUST: branding and photos
•Layout positioning
•Consistent choices and language

If returning to a cart later help user products
added and also promotes trust.

5 RECOGNITION OVER RECALL

•Avoid extra hurdles
•Legend vs. Visual both
•Font drop list preview
•Hybrid bread crumbs
SHOW and tell

25. 6 ERROR PREVENTION
Eliminate
error prone
conditions
https://github.com/kbwood/datepick
•Reduce bad input
•Confimation validation
•Dynamic form validation
•constrained options where relevant
•Auto-fill, auto-complete, auto-suggest
•Paste from Word (format stripping)
•Previews

26. 7 FLEXIBILITY AND EFFICIENCY
http://theme.wordpress.com/themes/illustratr/
Offer accelerators
customize
experience
for efficiency
EXAMPLES:
•Keyboard to nav (accesibility)
•Shotcut keys
•One click buy
•Screen options
•Wordpress 5 minute install

27. 8 AESTHETIC AND MINIMALIST DESIGN
Reduce unessesary
elements.
The more elements are competing
with relevant information.

28. Help users
recognize, diagnose
and recover from
errors.
•Notification wells
•Error tips
•404 offer solutions
•Mature and empathetic error
messages
9 HELP USERS WITH ERRORS

29. 10 HELP AND DOCUMENTATION
and make it easy
•CODEX, Code Poet
•Community answers, BuddyPress
•Online resources “Google your issue”
•FAQ, Knowledge base
•Customer service, Twitter
•Hyperlinks in contents to references
•Guided tours, First time hints

INTERACTIONCOST
“The sum of efforts—mental
and physical—that users must
deploy in interacting with a site
in order to reach their goals.”
EXAMPLE:
Task fatigue, confusion, lack of trust, too
much time waiting
Drop conversion and engagement suffer.
A “Bounce” is type drop off whereby the
user leaves within the first few seconds of
landing on the site.
