UX design focuses on the interaction between real human users and everyday products and services, such as websites and online apps.
User experience is a varied discipline, combining aspects of psychology, business, user research and design in order to make informed design decisions. This focuses mainly on why a user will interact with a product, how easy the product is to use and whether users can get to their end goal using a product without any pain points.
Website UX design focuses on the customer journey through your website from start to finish. The end user is always at the heart of the web UX design process to ensure a smooth user experience and the optimal performance of your site.
