Customer satisfaction depends on user experience (UX) and user interface (UI) design. When developed efficiently together, engagement increases. Without this, it is probable that users may go away from websites. Some studies mention that better UI could raise a website’s conversion rate by 200%. And better UX design could yield conversion rates of up to 400%. This statement makes it clear that good UI/UX is what we need. However, achieving perfection in these areas requires research, testing, experience and a good understanding about how efficient UI/UX can be accomplished in every particular scenario.
