The concepts of UI and UX don’t change depending on the niche. UI or user interface is an internal shell of your website the users interact with. The goal of UI is to provide visual aesthetics. UX or user experience, in turn, is about convenience. It covers impressions and feelings the users get when interacting with your eCommerce store. Talking about eCommerce user experience, modern customers expect the website to be fast, lightweight, and mobile devices. They would also like to see high-quality product photos, read detailed descriptions, have multiple payment options, and keep their financial data protected.
