In the UX/UI context, conversion refers to the process of turning a website or app visitor into an active user who completes a desired action, such as making a purchase, filling out a form, or subscribing to a newsletter. The term thus reflects the effectiveness of an interface in achieving its goals. A high conversion rate indicates that the interface is intuitive, user-friendly, and meets user needs. Optimizations that promote conversion include clear call-to-action buttons, well-structured content, and smooth navigation. Conversion optimization is therefore a key part of UX/UI design to enhance the efficiency of digital products.
