Business sites need to have a FAQ page for each product they sell. That is a great practice that could save your visitors some time getting answers to their questions. You can create your FAQ pages manually. Smart FAQ for WordPress is a handy plugin that makes creating and adding FAQ pages to your site easier.
Smart FAQ adds frequently asked questions to your site with answers hidden until the question is clicked. This makes your FAQ pages short while allowing you to include a ton of useful content on them. Add new items to your FAQ pages can’t be any easier.
Smart FAQ is free at the time of this writing. If you need a plugin to help you put a FAQ page together, you may want to give this plugin a look.
