Card sorting method

Definition

Card Sorting is a User Research method that helps organize information by allowing users to group content into categories. It’s particularly useful for structuring navigation in digital products.

What is it

In the context of navigation and Information Architecture, card sorting involves participants organizing topics or pieces of content into categories that make sense to them. This user-centric approach provides insights into how real users perceive and interact with information, guiding the design of navigation structures that are more intuitive.

How it works

Card sorting is typically conducted in two primary formats: open and closed.

  • Open card sorting allows participants to create their own categories. This is useful for exploratory projects where the existing structure may be unclear.
  • Closed card sorting provides predefined categories, guiding participants to sort content into these specific groups. This method is useful when refining an existing structure.

During the process, participants might arrange physical cards on a table or use online tools that simulate the experience. The outcomes highlight common themes and preferred categorizations among users.

When users find information easily, it leads to higher satisfaction, increased usability, and better Conversion rates. For businesses, a well-structured navigation system can reduce user frustration, increase engagement, and ultimately boost sales or user retention.
