Tree testing benefits
In this chapter, we look at the main benefits of tree testing: improved navigation and findability, identifying information architecture (IA) issues, and validating site structure before development.
Tree testing guide
Improved navigation and findability
Tree testing helps you identify whether users can find specific information quickly and in as few clicks as possible. By analyzing the results, you can identify areas where users struggle or take longer than expected to locate information.
For example, in the case of a lifestyle magazine, if a significant number of users mistakenly look for “Storage & organization” under “Home improvement” instead of “Housekeeping,” it indicates a potential reorganization opportunity to improve findability.
Identifying IA issues
Tree testing helps uncover IA issues such as duplicate paths, redundant categories, or dead-end paths that prevent users from finding what they're looking for. By analyzing usability metrics such as success rates, directness, and time to completion, you can quantify the severity of these issues.
Additionally, you can gather qualitative feedback by asking open-ended questions to gain deeper insights into users' frustrations or confusion. This information can guide you in making informed decisions to refine the IA and enhance the overall user experience.
The How tree testing works chapter includes a list of example follow-up questions that you can ask when doing tree testing.
Validating site structure before development
One of the key advantages of tree testing is its ability to validate the structure of your site or app early in the design process, before investing resources in development.
By conducting tree tests, you can identify and address navigation issues and usability problems at a stage where changes are relatively easy to implement. This saves time and effort in the long run, as it prevents the need for major structural changes or redesigns later on.
If tree testing reveals multiple IA usability issues, you can prioritize these changes in subsequent iterations, providing a more user-friendly and efficient product.
