A marketing packet is a PDF file placed on your site to help prospective clients learn more about your business and services. The marketing packet is specifically designed to aid gatekeepers/assistants to perform quick research on a company and then to take that information to their CEO. 

The biggest advantage of the marketing packet is that it enables the prospective client to quickly and easily research your company without spending a lot of their time trying to get info piecemeal which results in a bigger opportunity to gain new business.
