Why Does UI Matter?
The role of user interface (UI) design of digital products cannot be overlooked. The newest statistics of Adobe research indicate that approximately 73 percent of users abandon a web page or uninstall applications because of a rough or user-unfriendly interface design. Such data is the direct manifestation of the direct influence of good UI design on the rate of user retention.
Using the example of large e-commerce websites, Amazon and Target showed rather considerable changes in the conversion rate before and after the revision of the interface. Amazon simplified the process of procuring goods and made it more convenient to search and purchase, thus generating a 15 percent rise in sales. Target enhanced the design of the websites, and hence users spent 20 percent more time there. Such figures are convincing that creating a good UI design is not only a matter of appearance, but it also makes the users behave in a different way and helps businesses earn more money.
To designers, the user interface is what the user perceives first upon relating to a brand. It influences the attitude that customers develop towards the brand and their total experiences. A good UI design may boost user confidence and the competitiveness of the product. Thus, learning about the importance of UI design and learning to appreciate this value will be one of the connecting points that each designer should consider in the project.
