Before an effective advertising or public relations campaign can be created, you need to know your intended audience. Knowing your target market will determine the methods you use to reach them, what you say and how you say it. For example, an ad campaign geared toward college students isn’t going to have the same impact on middle-aged parents. And a public relations effort using business publications may reach upper management better than young professionals who rely on the Internet. Research can give you a detailed, robust picture of your potential market, including their demographics, psychographics, values, and more.
