User experience design is not just building websites, it's creating an online portal that visitors benefit from. Is a web site too cluttered? Is the page hard to read? Are the web site commands difficult to navigate? What is the actual point of my visit to this page?
User experience design determines the success of a web page by providing a positive experience to the visitor. The concepts help to create a web page that is easy to navigate, that offers concise directions on how to take the next step(s), and provides an interactive space where any questions and concerns are answered. In short, user experience design ensures the visitor gets value out of clicking on your web address.
