10 USABILITY PRINCIPLES FOR WEB DESIGN

1. Motivate – Design your website to meet specific user goals.

2. User Taskflow – What are your users tasks and online environment? For a site to be usable, page flow must match workflow.

3. Architecture – Build an efficient navigational structure. Remember if it can’t be found in 3 clicks; they’re gone.

4. Affordance makes obvious – Make controls understandable, avoiding confusion between emblems, banners, and buttons.

5. Replicate – and use consistent color, themes, and navigation throughout your web site.

6. Usability – Test users with prototypes early in the design. Don’t wait until the end when it’s too late.

7. Know technological limits – identify and optimize for target browsers and user hardware; test HTML, JavaScripts, etc. for compatibility.

8. Know user tolerances – they tend to be impatient. Design for a 2-10 second maximum download. Reuse graphics so they can be loaded from cache. Avoid excessive scrolling.

9. Multimedia – good animation attracts attention to specific information, then stops. Too much movement distracts reading and slows comprehension.

10. Use Stats – Monitor traffic through your site. Which pages pique user interest? Which pages make users leave? Adjust the site accordingly.
