When interacting with a client, an agency is tempted to consistently implement all of the client's edits - this is a simple solution, but it entails certain risks. What seems beautiful to an individual, especially one who does not specialize in web and UX design, will not always look good on a website and, moreover, be convenient for users. Surprisingly, even an interior designer may be completely incompetent when drawing web visuals, since each profession has its own specifics. Therefore, it is mexico phone number lookup
important to understand at least the basic principles of usability in order to evaluate the usability of a website or the design of your website.

Ease of use of the site. 10 heuristics of Jakob Nielsen
Below, using one of our projects (an online cosmetics store website) as an example, we will show the general things that are important for designing any effective and user-friendly website. 10 famous heuristics by Jakob Nielsen will help us with this . Jakob Nielsen is one of the leading experts in interface usability, the owner of dozens of patents and the author of books on this topic that have long become classics.
Back in 1998, he and his colleague Don Norman created the Nielsen Norman Group, which is the most authoritative consulting company in the field of user interfaces. It was Don Norman who actually came up with the term "usability" (user experience, user convenience) in 1993, when he was still working at Apple. The heuristics themselves have been relevant for almost 30 years (Nielsen wrote them in 1994), this is, in fact, a simple checklist with which you can check the quality of the usability of any interface.
1. System status
The user must always clearly understand what is happening now, and the system, in turn, must promptly give him an appropriate response.
We can demonstrate the work of this heuristic using the example of buttons – a modern user does not notice how buttons work, because their instant reactions have become something absolutely natural and, therefore, unnoticeable. But this unnoticeable work immediately becomes visible if something in the interface goes wrong and it immediately seems to us that the system does not work, has frozen, or for some other reason does not react or reacts differently than usual to our actions.
Buttons have different states of being pressed, which are reflected in the change of their appearance. For example, there are such important button statuses as focus - this is necessary, among other things, for those who use the keyboard instead of a mouse and for screen readers for visually impaired and blind users. This status is often missed. In addition, there are states of an active (pressed) button, a button with a mouse hover, and an inactive button - all of them help to understand what is happening now and what action the system is performing.

Instant reactions of the system also include the responsiveness of form fields, i.e. their ability to immediately respond to user actions. Thus, it is very important that an error about incorrect data entry occurs immediately, and not when sending a completed form, because forms can be longer than a screen/page and a person may not understand for a long time what happened. Our forms not only promptly respond to data entry, but also inform the user whether the data is entered correctly or not in the form.
An important field that should respond instantly is also the password input field - so our form fields inform the user that Caps Lock is pressed or the layout has not been changed to Latin. We will return to this point separately when discussing input errors .

2. Correspondence between the system and the real world
The design must speak the user's language and relate to his so-called mental model - ideas about how the site works, what its elements look like, what he can find and do on it.
In our case, several parameters are responsible for the system's correspondence to the real world, for example, interaction patterns - people will use the site in the same way as other online stores, so the client does not need to make any extra effort to make a purchase. The site's positioning and friendly tone also correspond to the ideas about the world.
