One of the best innovations in the history of websites is the FAQ function for frequently asked questions. Not only does it provide users with a great deal of professional and targeted information in a short period of time, it also reduces the use of resources. To ensure optimal usability, the topics should be divided into categories. Otherwise, the searcher may abort the search and possibly leave. In these two examples, the search can be narrowed down by clicking on the respective category. If the answer the user is looking for is not available, the person can still contact the responsible customer service.
