You have a goal of redesigning your website, but you first want to know which categories certain links should go under. Which research method should you use?

Card sorts help reveal how people naturally group information, which makes them useful for improving website navigation. This method supports website optimization because link categories should match user expectations rather than internal assumptions. It can show which labels or groupings feel intuitive before a redesign is finalized. Using this research method reduces friction by making the site structure easier for visitors to understand.
