When you should use card sorting

It’s best to do a card sort when you want to answer a specific, information-related question. For example:

  • Building the structure for a new website
  • Working out where a new category should sit on a website
  • Figuring out what should go on the homepage

Card sorting is most useful when you’ve got the information you need to organize, but you’re just not sure exactly how to organize it.
