#30: Do you explain benefits (not just features) in short or detailed product descriptions?
What are features? Features are defined as surface statements about your product, such as what it can do, its dimensions and specs, and so on.
What are the benefits? Benefits show the result of what a product can actually accomplish for a customer.
Benefits, not features - this is what really helps to sell a product to a customer. When you are selling any product, you are actually selling a certain experience: your product can simplify life, save time or money, make people beautiful or healthier, etc.
