In this presentation learn about some of the basics of mobile website usability including tap targets and zooming and scrolling.

1. Evaluating Mobile Usability Guidelines
Identifying Usability Criteria To Guide The Development Of A Mobile Presence
4. USABILITY GUIDELINES CONTINUED

2. Five Usability Guidelines
● Defining Mobile Intent & Purpose
● Increasing Perceived & Actual Load Speed
● Supporting Smaller Screen Sizes
● Supporting Touch
● Simplifying Form Usability

3. Mobile Intent & Purpose
● Mobile user needs
● Similarity to other needs
● Type of interaction

4. You need to understand your users
intentions and expectations, then measure
how well you are meeting those
expectations to know if your mobile
presence is even working.

5. Load Time
● Actual vs. perceived load time
● 700-900 milliseconds
● Impact on visitor’s memory

6. The longer the perceived load time, the
harder it is for users to remember what
they were doing on your site.
The harder it is to remember what they
were doing, the more likely it is that
people will give up on your site and leave.

7. Smaller Screens
● Google’s mobile friendly criteria
● Limit scrolling, avoid zooming
● Poorer user comprehension

8. ASK YOURSELF
How does my website perform?
Do users have to scroll and zoom on a
phone?
Does scolling and zooming create a
distraction? Is it impacting sales?
