Tree Testing Tool | Optimal Workshop


Information architecture validation software

Know where and why people get lost in your content

Tree testing is a usability technique for evaluating the findability of topics in a website. It’s also known as ‘reverse card sorting’ or ‘card-based classification’. Tree testing is done on a simplified text version of your site structure – without the influence of navigation aids and visual design.

Take the guesswork out of information architecture with Treejack – the usability testing tool you can use to test your IA without visual distractions. Treejack helps you prove your site structure will work before you get into interface design.

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.

It is so fast and easy to set up that it's really crazy not to use it.

Proving an information architecture

1. Input your tree

Your “tree” is the site structure of your website or intranet, your information architecture. Many times it is simplest to think of it as your sitemap.

2. Set your tasks

To find out if people can achieve what they came for on your website or intranet, you just need to enter the common tasks for your site, e.g. “Find the latest and greatest mobile phones.”

3. Recruit participants

We give you a unique study link that you can email to your users and customers, post on your website, tweet to the world, or use our integrated participant recruitment.

User centered information design

Your study participants will complete a tree testing activity online using their own computer. They will be asked to nominate where they'd expect to find the answers to a series of tasks using your information architecture.

Tree testing will help you understand:

  • Is my website or intranet content hierarchy well structured?
  • Is the taxonomy and navigation labelling appropriate?
  • Can people find what they're looking for?

Detailed path analysis

Affectionately known as the “pietree”, the detailed path analysis tool shows you where your participants went at each junction and where they all selected their final answers.

The destinations table gives you a quick overview of your tree, highlighting the correct answers and the probable problem areas where people incorrectly “found the answer”.
