Remote User Research Methods
for Information Architecture Testing

Card Sorting

Online card sorting is a simple technique in user experience design where a group of subject experts or “users”, however inexperienced with design, are guided to generate a category tree or folksonomy. It is a useful approach for designing information architecture, workflows, menu structure, or web site navigation paths.

Tree Testing

Tree testing is a usability technique for evaluating the findability of topics in a website. It is also known as reverse card sorting or card-based classification. Tree testing is done on a simplified text version of your site structure. This ensures that the structure is evaluated in isolation, nullifying the effects of navigational aids, visual design, and other factors.

First Impressions

First impression testing, or first click testing is a really simple remote usability testing technique for gathering user feedback on your designs and mockups. Upload images or screenshots, assign tasks and find out where people click first. This helps you decide which features to implement or change by testing by concepts and wireframes before building them.
