Card sorting is a highly useful technique in information architecture; it is used to understand how users think about your content. It can help you organize content so that it suits your users' mental models, rather than the point of view of your company.
How many participants do you need for a card sort?
Tullis and Wood recommend testing 20–30 users for card sorting. Based on their data, my recommendation is to test 15 users.
Is card sorting a usability test?
Card sorting is a conceptual activity, not a usability test or game of Snap. Your goal is to discover how people think about and make sense of your information, not whether or not they can find it quickly on a homepage.
