An FAQ page is an important tool that should be used to keep your customers/users/visitors informed and up to date. Creating and managing a FAQ page with Frequently will help limit the need for hands-on customer support, saving you time and money.
Our "Was this helpful?" buttons are a great way to measure how useful your FAQ is to your users as well as how comfortably they are with your service in general. If you are consistently getting not helpful votes on a question, it may be a great time to revisit the question at hand in order to fully help your customers.
