Research the Audience
Is there any way you can live a member of a market you are going to write for? Sure you can. You can subscribe and read the magazines people in the market read. Go to trade shows and other special events. Read the newsgroups and message forums on the Internet. Find others that live near you that are involved in the subject you are writing about. Are there local clubs you can join? Start with the magazines and web sites related to your field of interest and go from there. If you are writing from research or a topic you are interested in but still new at, this is a good way to approach it. What dreams does this person have? What is their income? Are they married? Do they have kids? The more you know about your audience the better.
