For those of us concerned with website usability, “card sorting” is a good way to get feedback from users on how to structure information. Traditionally done face-to-face, it involves getting testers to sort cards, each labelled with a topic, into categories. Find out more about how it works on usability.gov, or read what Jakob Nielsen has to say about it.
Card sorting can also be done online, providing quick access to a greater pool of testers. OptimalSort is a new online card sorting tool, currently in beta with free sign up until mid August 2007. I found it fast and easy to set up an open or closed card sort.
The best way to see how it works is to try completing this card sort I’ve set up. You’ll be helping our website redesign project too!
