You can use Treejack to:

  • See if people can find what they’re looking for on your website

Tree testing loves card sorting

Team up card sorting with tree testing for a deeper understanding of your users. Card sorting with OptimalSort helps you to understand how users group content, while tree testing will show if these groupings work — using both gives you the insights you need to improve your site structure.

Our suite gives you access to 5 research tools, including OptimalSort, giving you the flexibility to test and iterate your ideas with ease.

Treejack is a great tool for testing out a multi-leveled IA. The results gave me an instant appreciation of what was working and what was not.
