User Experience is the Key Fact of Web usability
The usability of a website is also often confused with user experience, which is a related web design concept (UX). The best way to think about website usability is as a subset of UX. This is because UX usually refers to a wider field of study and design than just web interactions. UX includes everything from how people interact with machines to the anthropology of AI. Most courses on user experience point out that the lessons they teach can be used in a huge variety of situations and devices, not just websites.
