A large website is typically organized into a hierarchy (a "tree") of topics and subtopics.[3][4] Tree testing provides a way to measure how well users can find items in this hierarchy.[5][6]
Unlike traditional usability testing, tree testing is not done on the website itself; instead, a simplified text version of the site structure is used.[1] This ensures that the structure is evaluated in isolation, nullifying the effects of navigational aids, visual design, and other factors.[7]
