Know where and why people get lost in your content, and fix it. Tree testing helps you evaluate the findability of topics on your website. Whether you’re starting fresh or improving your existing website, Treejack is the perfect tool to get the insights you need to build an intuitive information architecture. 

Discover how your audience finds what they’re looking for

Take the guesswork out of your design decisions. Treejack helps you understand where people are currently getting lost and how they expect to look for key information on your website. The easier your website is to navigate, the bigger the likelihood people will come back (which is a win for you).
