Copy-editing takes your raw material – a website, article, flyer, newsletter – and makes it ready for publication. Its aim is to ensure that whatever appears in public is accurate, easy to follow, and free of error, omission, inconsistency and repetition.
You can't overstate the importance of copy editing. A professional editor will improve your copy, both grammatically and creatively, and ensure the ideas you want to portray are clear and easy to understand.
