Summary of Usability Issues « Usability 5
Inconsistent global and sub navigation
- Placement inconsistent relative to page and each other
- Inconsistent content and links
- Missing navigation
- Logo not linked to home (not following established navigation conventions)
- Dead ends trigger back button escape mode
- Inconsistent footer navigation—legal, copyright, privacy, accessibility
Missing "just-in-time" navigation
- Lacking navigation elements that provide sitewide help to users at any time
- Lacking navigation support for frequent and common global (sitewide) actions such as search, site map, login, contact
Poor information organization and hierarchy
- 2-D, flat organization (not enough drill-down)
- Too much drill-down (no breadcrumbs to extricate)
- Lack of organization impedes semantic HTML markup
Poor visual hierarchy and user feedback
- Unclear about first action to take
- Unclear about what information is important
- Where am I? Which department, which site section... which academic institution?
Too many words and poor choice of words
- Paths to information obscured by overwriting
- Needless didactic text accompanying basic precepts
- "Click here" as a call to action is vague, uncompelling, and a problem for disabled users browsing with screenreaders.
- Different words for similar processes generate confusion
