The abbreviations UX and UI are often mentioned, above all in the digital world. But what lies behind them and why should businesses take quality UX and UI design into account?

In today's digital world the competition on the internet is enormous. Users have endless options and only a few seconds to decide whether to stay on your page or leave it. If you want to create a site that not only catches attention but at the same time effectively meets your business goals, you have to pay attention to UX and UI design. 

Quality design is not only about aesthetics but above all about creating an experience that turns visitors into satisfied, loyal customers. What exactly do these abbreviations mean? Why are they key to your website's success? Read on, we will be glad to explain.

What is UI design? (User Interface)

UI (User Interface) deals with a site's visual side. It covers everything users see and interact with directly. The key elements of UI design are:

  • Colours: suitably chosen colours can evoke the right emotions and support the brand identity.
  • Typography: choosing the right font raises legibility and a professional look.
  • Icons: they help users quickly grasp the functions and options.
  • Layout: an effective layout ensures finding your way around the page is simple.

What is UX design? (User Experience)

UX (User Experience) deals with a user's overall experience when interacting with a site. It is not only about the visual side but about the feeling and overall satisfaction from using a website. UX design focuses on:

  • Researching users and analysing their needs: finding out what users expect from a site and what they need.
  • Designing the information architecture and navigation: arranging information so that it is easy to reach.
  • UX testing or usability testing: gaining feedback from real users to uncover and remove problems.

Creating wireframes and prototypes: creating visual designs and testing how a site works before it is developed. Have you heard of the design thinking method?

What is the difference between UI and UX?

UI and UX are often confused, but there are clear differences between them:

Characteristic UI (User Interface) UX (User Experience)
Aim An attractive look and interaction The user's satisfaction and easy usability
Process Designing visual elements Research, testing and optimising the experience
Outputs Colours, icons, typography Wireframes, prototypes, information architecture

Both areas are essential to a website's success and you will achieve the best result if they complement each other.

Why does UI/UX design matter for a website's success?

Quality UI/UX design brings plenty of advantages that are closely connected and together help a website achieve success. Users prefer pages that are simple, clear and pleasant to use. When visitors have a positive experience, they are more satisfied, which directly leads to greater loyalty on their part. This satisfaction at the same time supports better business results, because satisfied users much more often carry out the actions you want, such as a purchase or a registration. Thanks to thorough UI/UX design you can also uncover and remove problems in time, which markedly lowers the costs of developing and then maintaining a site. Besides that, professionally handled design supports a positive perception of your brand and builds its credibility. Users perceive quality design as proof of seriousness and professionalism, which in the long term strengthens a company's image and its competitive advantage.
