Reference table
What is a good tree test success rate?
Benchmarks for reading a tree test success rate, from below 50% (a serious findability problem) to 80% and above (strong). They help teams set a target before testing and judge a result without overreacting. The bands follow Nielsen Norman Group and MeasuringU guidance. Live websites usually score about 20% higher than the tree test for the same structure, so read a middling result as a starting point.
