Web Design : The Importance of Usability
Usability is a quality attribute that describes how easy a user can navigate or use the user interface of software, and in the context of web design, the design and navigation of the website. According to Jakob Nielsen, a pioneer and pillar in usability, usability is defined by five main components: learnability, efficiency, memorability, errors and satisfaction.
Usability in web design is very important because it is a very big factor that determines the success of your website. If users fail to “know��? what your site is about in the home page, they will leave as soon as they arrive. If your navigation is clumsily design and is not intuitive, your user may not get to the part of your site that’s important to them and then will leave. If your color scheme makes the readability of your text suffer, people will not hesitate to look for information somewhere else, after they leave. The importance of usability in web design is even more important than in software applications because in the web, there is virtually no barrier that will prevent your user from leaving your site and going somewhere else. If they find that your website sucks, they will leave, and you will lose a very important metric of website success: traffic.
Now that I have stated the importance of usability, you should take it as one of the key factors to consider and spend time on during the design of your website. Usability should not be a design afterthought. In fact, if you want to design a successful website, usability should be at the core of your website design.
