Having an internet presence helps to reach new and existing customers as your website contains all the information about your business. Consumers can go online 24 hours a day, seven days a week to get answers and information about your business, even if your business is closed for the day. Marketing is done by providing information, not by persuasion.
Creating an internet presence doesn't have to be difficult or costly. It can be as simple as having a one page website explaining your business to a potential customer. A web site is not constrained by size. You can only say so much in a newspaper ad, or a radio spot. You can supplement that limited information by including your web address in your ads. Then your potential client has almost unlimited information about your company available to them.
