Abstract:

Technical communication consultants may find that marketing writing makes an excellent second line of business. Technology companies, marketing services firms, and advertising agencies often use freelancers to write marketing documents. They particularly need good writers who understand technology. This paper discusses the business of freelance marketing writing and how it differs from independent technical writing. Topics include the kinds of projects that marketing writers work on, how development cycles typically differ from those of technical documents, and how to effectively market yourself as a marketing writer.
