Web site user interface testing is conducted to find out how quickly and easily unique web site visitors find information on sites. Testing involves watching users maneuver through a web site and determining if the site is designed and formatted properly based upon actual users' experiences. Testing surfaces - user frustrations, unique searching methods and user-friendly features of a web site.

Upon completing testing with a representative sample, a web site may be redesigned with confidence that a user will understand how to locate information and how to purchase products on the web site.
