When we talk about usability in web design, we are talking about the
overall ease and comfort with which site visitors can complete the tasks
associated with a given website. From simply finding the information
they are looking for, to completing a purchase - how easy is it for
visitors to do what they need to do on the site?
Various elements contribute to site usability, including:
- Familiarity - does the website use common, familiar navigation - will the user find the site easy to move around in?
- Easy to learn - is the site designed to make it as easy as possible for new visitors to figure out?
- Efficiency - is the site logically designed so that users can quickly complete desired/required tasks?
- Memorable - does the site design make it easy for a returning visitor to remember how it works?
- Error Frequency - how often do site users make mistakes - how much of a problem does an error create and how difficult is it for the site user to recover and get back on track after making a mistake? Has every effort been made to minimize errors and their consequences?
- User Satisfaction - the fun factor...is the site enjoyable to use?
