Another case for hiring professional copywriters—a white paper by Robert Roth.
Remember the line from George Orwell's Animal Farm: "All animals are equal, but some animals are more equal than others" It's the same with writers. Professional copywriters often bring an added value to the project. For one thing, professional copywriters write all the time (at least the good ones do), so they have a rich depth of experience in a variety of industries. Second: professional copywriters are skilled at managing the elements that make copy easy and enjoyable to read – things like tone, clarity, rhythm, cadence and sentence length. Third and perhaps the most important: professional copywriters bring a creative point of view to the project.
