User experience (UX) is the buzzword for most companies with any sort of online presence or making an app for a variety of user these days.
UX design is not the same as graphic or visual design that as many of we think, though the two often work hand-in-hand.
UX designers are not focused so much on how a site looks, besides, how the site or mobile app works for a consumer and how user-friendly it is.
The web designer and app developer build the maze, while the UX designer guides the user through it.
UX design also focuses on ensuring that users of the site or mobile app have a good experience regardless of what platform they are using – something that is increasingly important to the growth of people accessing the internet on mobile devices.
Ultimately, good UX design should ensure that people hang around longer on your site or app, increasing your user count and, in the case of e-commerce websites or app, increasing the chance of someone making a purchase and recommending your site or app to others.
