01 / THE IDEA
What does it mean?
Tree testing evaluates information findability through text-only navigation, without visual styling affecting choices.
02 / IN PRACTICE
Make it concrete.
Illustrative example: Participants try to find “download tax invoice” in a proposed account menu hierarchy.
03 / WHAT TO WATCH FOR
A common mistake.
Assuming a successful tree test means the entire interface is usable.
04 / WHEN IT HELPS
When should you use it?
When you need to validate navigation labels and hierarchy before visual design.
