Accessibility and usability are closely linked, but the former is more concerned with specific issues of disability and the latter is more to do with the general user experience.

A usable website is one which offers:

• ease and efficiency of learning – people who have never seen it before can quickly learn how to complete basic tasks and the site allows the rapid accomplishment of tasks by more experienced users
• memorability – casual users of the site are assisted by an interface design that they can remember how to use
• effective – visitors are able to fully complete tasks and get the right results
• error minimisation – the number and severity of errors are minimised, and the site allows for quick recovery from the error
• attractive design – visiting the site is a pleasant experience for the user
• accessibility – users are not excluded from the site by technological or other barriers
• rapidity – the site allows for fast download of information; including when access is via dial-up connections rather than broadband
• content rich pages, well written, well organised and structured, with simple and consistent navigation
• clearly written – the author has used plain English and web writing guidelines
