Having a list of frequently asked questions, or FAQ's, available for your customers can do wonders. This works particularly well on websites where people are trying to gather some facts on their own and can quickly get their questions answered.
Internally compiling FAQ's helps you determine what people ask the most. You can then address these concerns up front in your marketing. It is also great preperation for you sales people. If they already know what people are asking the most they can be prepared with some good answers before they make the call.
What are your FAQ's? Where do you post them for customers and employees?
