Your website is the center of all of your marketing. As any trust worthy marketing expert would tell you, the first marketing step for any business is to have a great site that is optimized for user experience and the search engines. Any information that you deem to be useful or helpful for clients, should be put on your website first and foremost. Physical marketing mediums; for example: brochures, fliers, business card, etc: still have their place in business; but, they should always reference your website as a top reference point to get more information. Your website can then convert those visitors into new clients.
