| Can people who come to your site find what they need? Can
they accomplish tasks such as completing surveys, taking quizzes, and so on?
The study of the Usability of a site helps ensure that the
answers to these and similar questions is "Yes." Usability can be divided
into five components:
- Learnability: can people learn to use your site quickly and
easily?
- Memorability: when people return to your site, can they recall
how to use it?
- Efficiency: can users do what they need to do without excess
expenditure of energy and time?
- Error rates: how often to people make mistakes (such as
getting lost, going to the wrong place, and so on) when using your site?
- Satisfaction: what is the subjective reaction of users to your
site?
