"Great copywriters like to know exactly what they will be writing. Many times, assignments are vague. It's important to spell out in clear, simple terms, what the writer needs to know to do his best work. Sometimes the target audience is vague. Other times the features and benefits of the product are unclear. In addition, a great copywriter needs to know the reason for the assignment. Is the client introducing a new product or service? Are they trying to qualify prospects? This is a critically significant piece of the project.
"Make sure you give the copywriter all the background material they need to write the copy. Types of things they need are previous ads, testimonials, product brochures, market research, and information on the competitors. Having these materials makes the project so much easier."
