Building a site structure based on what makes sense to your team is one of the most common – and costly – mistakes in UX. Until you test it with real users, you don't actually know if people can find what they're looking for.
What you'll learn in this tutorial:
How to set up a tree test to evaluate your site structure or proposed navigation.
How to write realistic task scenarios that reveal where your navigation breaks down.
How to recruit targeted participants quickly using the Lyssna panel.
How to read success rate and directness scores to identify what's working and what isn't.
How to use a card sort alongside a tree test to fix the problems you uncover.
Whether you're redesigning your information architecture or validating a new site structure before development begins, this playbook gives you a clear, repeatable process for getting your navigation right before it's built.
Key takeaway: A high success rate and a low directness score are a warning sign – users can recover, but they're wasting time getting there.
