Proofreading vs. Copyediting vs. Developmental Editing: What’s the Difference?


By Leslie Norris November 23, 2025

And which one do you actually need?

If you’re an author, whether you’re writing your first book or your fifteenth, you’ve probably heard all kinds of editing terms thrown around: proofreading, copyediting, developmental editing and maybe wondered, Okay, but what’s the difference?


At Author Loot, we help authors navigate the publishing world without the confusion. Here’s a simple breakdown of what each editing stage really means and when you might need it.


Developmental Editing: The Big-Picture Fix


Think of this as the “story-level edit.” A developmental editor dives into the heart of your book, its structure, pacing, characters, worldbuilding, plot arcs, themes, and overall clarity.


A developmental edit helps you with:


  • Plot holes or slow pacing
  • Character motivation and consistency
  • Worldbuilding depth
  • Chapter flow
  • Story cohesion
  • Tone and audience appropriateness


This is the stage that strengthens the bones of your story. You’ll receive feedback, suggestions, and sometimes chapter-by-chapter notes to help you revise. If your manuscript is still taking shape or feels “off,” this is where to start.


Best for: Early drafts, books that need shaping, and authors who want detailed guidance.


Copyediting: The Line-by-Line Polish


Once your story structure is solid, copyediting tightens the writing itself. A copyeditor focuses on the words on the page, making your prose clear, consistent, and professional.


A copyedit focuses on:


  • Grammar, punctuation, and sentence flow
  • Clarity and readability
  • Repetition and word choice
  • Style guide consistency
  • Continuity (character names, timeline details, etc.)


Think of it like smoothing wrinkles out of a shirt. Your story stays the same, but it reads cleaner, sharper, and more refined.


Best for: Manuscripts that are structurally sound but need a professional polish.


Proofreading: The Final Check


Proofreading is the very last step before publishing. It’s not rewriting, it’s catching mistakes that slipped through all the other editing stages.


A proofreader checks for:


  • Typos
  • Misspelled words
  • Missing or doubled words
  • Final punctuation errors
  • Formatting inconsistencies


This is your safety net before your book goes out into the world. No major changes happen here, just cleanup.


Best for: The version you’re ready to upload to KDP, IngramSpark, or your printer.


How the Stages Work Together


Here’s the simplest way to think about it:


Developmental Editing → Fix the story


Copyediting → Fix the writing


Proofreading → Fix the typos


Skipping steps can lead to frustration (and unnecessary republishing fees), so most authors use all three at different stages, even traditionally published ones.


Which One Do You Need?


At Author Loot, we help you choose the right level of editing based on where your manuscript is in its journey. Whether you need big-picture guidance, line-level clean-up, or a final polish before launch, we make the editing process simple, approachable, and author-friendly.


If you’re unsure where your book stands, we can review a sample and recommend the best path forward. Your story deserves the strongest possible version of itself, and we’re here to help you bring it to life.

As the holiday season kicks off, there’s one gift that never goes out of style: a good story. And behind so many of those unforgettable stories are indie authors, writers who pour their heart, time, and energy into creating worlds for us to escape into. This Black Friday, we want to shine a spotlight on them. Why Indie Authors Need Us More Than Ever Most indie authors aren’t sitting on bestseller lists or topping algorithm charts. They’re writing late at night, designing graphics on their lunch break, learning advertising on the fly, and juggling every piece of publishing that big publishing houses normally handle. Indie publishing is empowering, but it also means authors are often their own: Marketing team Publicist Editor Designer Social media manager And somehow still… full-time writer So when you support an indie author, you’re not just buying a book, you’re helping keep their dream alive. Your Holiday Challenge: Pick One Indie Author This week, take a moment to choose one indie author you know or follow. Maybe it’s a friend. Maybe it’s someone whose posts you always scroll past with a little smile. Maybe it’s the writer who’s quietly published five books while raising kids, working a job, and fighting the algorithm gods. Pick one of their books and grab a copy. Think of it as tossing a coin to your Witcher 👈 . Yes, I made that reference. If you don't know, tossing a coin is a small gesture that means the world to the one receiving it. Then Share the Love Buy The Book. This step is how you help them find their next reader. Post about the book on your favorite social platform. Share a picture or even just the cover Tag the author’s page Add a kind word about why you picked it That tiny act of visibility can be the spark that helps them reach a brand new audience. Why This Matters Readers underestimate how much power they have. One post. One share. One review. One tag. It all stacks up. Indie authors don’t have giant marketing budgets backing them. They have community . (That's you.) This holiday, let’s show them how strong that community can be. We’re Here to Help At Author Loot, we know exactly how hard indie marketing can be, because we live and breathe it every day. We help authors build websites, grow their platforms, launch their books, and reach their readers without burning themselves out.  If you’re an author who needs support, or a reader who wants to discover new stories, we’re here for you . Let’s make this the year indie authors get the attention, love, and boost they deserve.
