Poor usability leads to irritation and fatigue and it has an adverse impact on the usage experience. In an on-line shopping web site, it can lead to loss of revenues.

A highly usable on-line shopping web site tempts repeat visits, builds customer loyalty, and increases its revenue-earning potential.
