User Experience (UX)

#### User Experience (UX) is the overall perception and feeling a person has when interacting with a product, system, or service, such as a website. In the context of web performance, a good UX means the site feels fast, responsive, visually stable, and is easy and intuitive to use. Improving UX is the ultimate goal of all performance optimization efforts, as it directly leads to happier users and better business outcomes.
