User Experience design is often an overlooked element when it comes to websites or mobile apps. When you have users interacting with a product, it’s important that the design leads the user through a positive and enjoyable experience.
Ever fill out a form and accidentally hit a link? When you click on the back button, you come back to an empty form with all the information gone? That is not a good experience. On average a website has hundreds of interactions that need to designed with the user in mind. Just remember: a happy user is a returning user.
