Your website is often the first impression potential customers  have of your business. A well designed website will ensure that the first impression is a good one, and helps those potential customers decide to contact or visit you. 

Your website is also important for retaining existing customers. Communicate with them about events and special offers. Provide information about your business that people can access 24 hours a day, at a time that's suitable for them. And of course, if you are selling products online those orders can come in 24 hours a day too.
