What is tree testing used for in web development?

Tree testing is specifically designed to evaluate the usability of website topics by examining how effectively users can navigate a site's information architecture. This method allows developers and designers to verify whether users can find items in a hierarchy based on the labels and structure provided. During a tree test, users are asked to complete specific tasks that require them to find information using the site's navigation system without any visual design elements, thus focusing purely on usability and the clarity of the content organization.

The result of tree testing provides valuable feedback on how intuitive and user-friendly the navigation pathways are, helping teams understand potential areas of confusion in the categorization of topics. This insight is crucial for improving user experience, ensuring that the information is easily accessible and logically structured.

In contrast, measuring website traffic pertains to analytics and visitor metrics, which does not directly assess usability or information design. Designing website graphics relates to the visual aspect of web design rather than its navigational effectiveness. Assessing content quality, while important for user engagement, does not focus on the structural navigation pathways that tree testing targets.
