As a freelance copy editor, your job is to review spelling, grammar, and previous editing of a piece of content. Content can range from small pieces of less than two hundred words to complete books or manuscripts. Some freelance copy editors focus on particular types of content, such as medical content or the format of textbooks. In this role, you may proofread significant amounts of content each day, extrapolate the overall quality of work from a sample of it, and communicate with other editors to explain how much content needs to change. Some freelance copy editors edit the same material through several drafts, so the ability to remain focused while reviewing similar content is essential to your success.
