The goal of usability is to ensure a good user experience so that the user can achieve their goals without frustration. It involves building a system that is easy to use, reliable, and that motivates the user to return.

The five main components of usability
Jakob Nielsen , a reference in usability and user experience, highlights five essential elements for the usability of interfaces:

Ease of use: The interface should be intuitive, allowing users to perform basic tasks the first time.
Efficiency of use: After understanding how it works, the user should be able to perform tasks quickly and smoothly.
Memorability: Even after a period of inactivity, the user should be able to find their way around easily when returning.

When users have difficulty performing any task in an interface, it indicates usability issues.

Most common usability problems on websites
Some of the most common errors seen on websites that end up harming the user experience are these:

Navigation difficulties: When users have difficulty finding information, returning to a specific page or encountering many broken links, for example, navigation becomes frustrating and the chances of them abandoning the site increase.
Too many visual elements: Excessive use of colors, highlighted text or too many elements can make the page visually cluttered. This confuses the user and makes navigation difficult, making the experience tiring and less efficient.
Non-responsive design: Websites that don’t adapt well to different devices, such as smartphones and tablets , compromise usability. Responsive design ensures that the website functions properly on any screen.
Slow loading times: Pages that take too long to load drive users away, especially those with slower connections. Poorly optimized sites with too much heavy content end up harming the experience and increasing the abandonment rate.
Incompatibility between browsers: The lack of compatibility between different browsers, such as Chrome, Firefox and Safari, may affect the functioning of the website. To ensure a good experience for all users, it is essential to test and adjust the website for each browser.

How to evaluate the usability of a website?
Usability assessment allows you to identify problems in the interface and improve the user experience. There are several ways to carry out this assessment, the main ones being:

Usability testing: This involves observing real users navigating the website and recording any difficulties or issues they encounter. This method provides direct insights into the user experience.
Heuristic analysis: This involves evaluating the website based on usability principles, such as consistency, clarity of language, user feedback, among others. It is an efficient way to detect flaws using established guidelines.
Navigation analysis: Evaluates the structure and clarity of navigation, labels and the effectiveness of the website tools. This ensures that the user can move around the website intuitively and without barriers.
Indirect observation: Uses tools such as Google Analytics to analyze user behavior, identifying critical points, such as exit pages or time spent in certain areas of the website.
How to avoid usability problems
Ensuring a website’s usability requires attention to several elements during development. Focusing on these aspects can minimize issues and significantly improve the user experience, as well as increase the effectiveness of the website. Let’s explore the essential points:

Standardized layout
Layout consistency is necessary for intuitive and efficient navigation. It’s not just about aesthetics, but about keeping elements like the navigation bar, header, and footer in the same place on every page. This creates familiarity for the user, making navigation easier.

Additionally, a uniform color and font scheme reinforces the visual identity and improves the experience, allowing information to be located quickly.

Good browsing speed
Website speed directly affects user experience. To ensure that pages load quickly, it is essential to optimize images, use CSS and JavaScript efficiently, and manage server load well.

Having a fast website also has a positive impact on SEO, increasing the chances of ranking better in search engines, which prioritize websites with good performance.
