Copywriting is not really an editing service. If you have landed on this page expecting to learn how to have your work copyrighted, click here. And if you want your work corrected, you want to go to the page about copy editors.
But if you want to know about copywriting, read on.
Copywriters use words to create publicity. They may write copy for the blurb of your book, contents for a brochure about your book or the workshops you present, press releases, or Web site content. What they write does not define them as much as the intended result of what they write. They intend to sell.
A good copywriter knows markets, is a master with words, and is highly creative.
