Tree Testing
Tree testing is a research method that evaluates the findability of topics in an information architecture hierarchy in isolation from visual design.
Also called reverse card sorting, participants navigate a simplified, text-only tree structure to find specific items. Because visual cues, search boxes, and branding are stripped away, it isolates navigation performance cleanly.
How it works
Users are given realistic scenarios like 'Where would you change your billing notification email?' and click down through text category branches. The test records task success, directness, and backtracking paths.
When to use it
Run tree tests after drafting an information architecture or sitemap, but before designing page layouts or menu components.
Trade-offs
It produces clear, objective findability data quickly, but lacks context on how visual cues like icons or promotional banners might guide users in the real app.
Key takeaways
- Tests navigation hierarchy findability without visual design interference.
- Reveals whether category labels make sense to users before building menus.
- Tracks both task completion and how much backtracking users did to get there.

Common questions
- How does tree testing differ from card sorting?
- Card sorting helps you discover how users group topics into categories, while tree testing verifies if users can find items within a proposed category structure.
