In web pages, especially in very large ones, many internal URLs can be generated.
Sometimes it happens that the user reaches a certain space on the web and does not know how he got there, so he would not know how to access it again if he wanted to return in the future. A simple way to avoid this and that will also benefit you in terms of SEO positioning, is to make sure you have friendly URLs on your website.
Friendly URLs are those that do not contain special characters such as “?”, “&” or “=”, but merely indicate in which section of the web the user is at that moment.
For example, an unfriendly URL would be: http://www.example.com/index.php/?3dse3?=32 and a friendly URL would be: http://www.example.com/ebooks/5-tricks- web-usability.

In the first case, the user would not know in which part of the web they are, since the URL does not have a logical content. In contrast, in the second example, the user would know that if he wants to go back to the site where he is, he would only have to access the sections that appear in the URL.
Friendly URLs make it extremely easy for the user to know their location on the web at all times, which improves their web experience and, therefore, its usability.
