Navigation is one of the most essential elements when talking about usability. Basically, it is a tool that allows the user to visit all the main pages that exist on a website. So, as you can see, it is an element of great importance in every website. An essential feature of the navigation bar is that it should be simple. If the structure of the navigation is too complex, it is unlikely that the user will stay long enough to decipher it and affect the bounce rate.
In websites with a large volume of content, it is quite likely that the menu has different levels. In certain places, you cannot avoid a situation like this. However, if your menu has more than 3 levels, maybe you should consider analyzing the structure of your site. Remember that navigation should be simplified for users. Otherwise, they are likely to decide to terminate your visit ahead of time.
Include a search bar:
The search bar can boost the navigation of a website. Regardless of the content volume of your site, you should include a search bar because it is possible that a part of your users uses it to go directly to the page you are looking for. Depending on the type of site, the search bar will have more features and can be quite sophisticated. For example, an online store with a large number of products needs to offer access to various filters to make the search result more specific.
Readability is another key factor to be able to create a web design that is easy to use. Users must be able to find and understand the information they are looking for without making a big effort. To do this, you should not only make sure to use a simple and familiar language for your visitors but also take into account other issues such as the color and the font used.
