You run usability tests on your designs, but do you test the structure of your site? How do you know it’s better than the old site? Online tree testing lets you test several proposed site structures against each other to see which is most effective. You get quick objective feedback from real users early in the design process. We start with tree-testing concepts and run a live tree test, then dive into the how-to’s of running a good study and the lessons we’ve learned from several high-profile projects. It’s a great chance to add another practical technique to your design toolkit.
