Copy Editing
The most detail-oriented of all editing types is copy editing. This is where editors fix every hidden grammatical mistake and painstakingly ensure the author’s manuscript matches its style guide.
Content Editing
Content editing is the process of working directly with the author to fully develop ideas, optimize organization, and perfect arguments pre-copy editing.
Developmental Editing
Also called “story coaching,” developmental editing is a coaching and editorial process that helps the author develop the most complete story in terms of essential elements like plot, characterization, pacing, and more.
