Don’t Make These 8 Mistakes When Writing a Bestseller

This entry is part 4 of 8 in the series Write a Bestseller

Most books that fail don’t fail because the writing is terrible. They fail because the author made avoidable mistakes in structure, characters, pacing, or marketing. The writing might be competent, even good, but something about the execution keeps readers from finishing, recommending, or remembering the book.

These are the most common problems, with examples of books that got it right.

Ignoring What Readers Expect from the Genre

Every genre comes with reader expectations. Romance readers expect emotional depth and a satisfying resolution. Thriller readers expect suspense and escalating stakes. Fantasy readers expect consistent world-building. If you write a romance novel that spends most of its pages on unrelated subplots instead of character relationships, you’ll lose your audience regardless of how well those subplots are written.

This doesn’t mean being formulaic. It means understanding what drew readers to your genre in the first place and delivering on that promise while adding your own voice. Research bestsellers in your genre on Goodreads and pay attention to reviews. They reveal what readers value and what disappoints them.

Weak Characters

Characters are the reason readers keep turning pages. If readers can’t connect with your protagonist, nothing else matters. Bestselling books have characters with relatable flaws, clear motivations, and genuine growth. Santiago in The Alchemist by Paulo Coelho resonates because his struggle to find purpose is universal.

Flat characters come from authors who know what their characters do but not why they do it. Build character profiles that go beyond physical description. Include their backstory, fears, ambitions, and internal conflicts. Weave those elements into the narrative so characters feel like people rather than plot devices.

Pacing Problems

Pacing is the rhythm of your story. Too fast and readers can’t connect emotionally. Too slow and they lose interest. The balance comes from alternating high-energy scenes with slower, reflective moments that let readers process what happened and anticipate what’s coming.

The Da Vinci Code by Dan Brown is a masterclass in pacing. Short chapters, cliffhanger endings, and strategically placed reflective moments create a rhythm that keeps readers moving through the book. Outline your pacing before you start writing. Plan high-stakes scenes and follow them with chapters that let readers breathe. Read your work aloud to hear where the story drags or rushes.

Skipping Revision

First drafts are not finished books. Most bestsellers go through multiple rounds of editing to refine plot, deepen characters, and improve readability. Skipping or rushing revision is how plot holes survive, inconsistencies go unnoticed, and good stories end up feeling unfinished.

Set your draft aside for a few weeks before revising. The distance gives you perspective you can’t get while you’re still inside the story. Hire a professional editor or use beta readers for feedback. They’ll catch problems you’ve become blind to after months of working on the same manuscript.

Weak Openings and Endings

Your opening determines whether readers keep going. Your ending determines whether they recommend the book. Gone Girl by Gillian Flynn opens with a gripping narrative that pulls readers in immediately, and the twist ending keeps them talking long after they finish.

Start with a question, a vivid image, or a moment of tension. Don’t start with backstory, weather, or a character waking up. For your ending, resolve key conflicts or leave readers with something to think about. A satisfying ending doesn’t have to be happy, but it does have to feel earned.

No Emotional Stakes

Without emotional stakes, even the most compelling plot feels flat. Readers care about outcomes because they care about characters, and they care about characters because those characters have something real to lose. To Kill a Mockingbird works because Scout’s emotional journey and moral challenges make readers personally invested in the outcome.

Ask yourself what your character stands to lose. Not just physically but emotionally, relationally, psychologically. Craft scenes that show how much the outcome matters to them. When readers feel the weight of what’s at stake, they can’t put the book down.

No Marketing Plan

The best-written book in the world fails if nobody knows it exists. Atomic Habits by James Clear became a bestseller through consistent, targeted promotion across multiple platforms, not because it magically found its audience.

Marketing isn’t optional and it’s not something you figure out after the book is published. Create a marketing plan before your launch. Identify where your readers spend time online. Use Amazon Ads, social media campaigns, email lists, and collaborations with influencers in your genre. An author website where readers can connect with you directly is essential.

Ignoring Reader Feedback

Reader feedback and genre trends tell you what’s resonating with audiences right now. Staying true to your vision matters, but writing in a vacuum is how authors produce books nobody wants to read. Sites like Goodreads and Amazon reviews provide feedback that can guide refinement of your story, your marketing approach, and your next project.

Letting Theme Overpower Character

Strong themes make stories memorable. But when a theme becomes the point of the character rather than something the character navigates, you end up with a protagonist who feels like a message instead of a person. This happens most often with “empowerment” arcs where the character is written to be impressive rather than interesting.

The difference is vulnerability. A character who is powerful and struggles with what that power costs them is compelling. A character who is powerful and never faces a real challenge is a poster. Readers connect with characters who grow through adversity, not characters who arrive fully formed and dominate every scene.

To write empowerment themes that work, give the character real flaws that aren’t cosmetic. Let them make mistakes that have consequences. Let them lose sometimes. Let other characters challenge them in ways that require growth, not just force. The theme should emerge from the character’s journey, not the other way around.

Some examples of empowerment done right: Furiosa in Mad Max: Fury Road is relentless and capable, but she’s also desperate, traumatized, and operating from a place of loss. Her strength feels earned because we see what it costs her. Ripley in Aliens isn’t powerful because the script says so. She’s powerful because she makes hard decisions under impossible pressure and survives through resourcefulness, not invincibility.

The Rings of Power Problem: When Theme Overrides Lore

Amazon’s The Lord of the Rings: The Rings of Power illustrates what happens when theme overshadows everything else. The show had a massive budget, access to Tolkien’s world, and a built-in audience. It stumbled because its version of Galadriel was written as a fierce, nearly invulnerable warrior whose personality served a modern empowerment theme rather than emerging from the character’s history, relationships, and internal conflicts.

Tolkien’s Galadriel is powerful, wise, and aware of the weight of power. She’s compelling because of her restraint, her temptation, and her self-knowledge. The show’s Galadriel dominated every situation physically, which left no room for the kind of growth that makes characters interesting. When a character can overpower every obstacle, there’s no tension. When there’s no tension, there’s no story.

The fix isn’t to make characters weaker. It’s to give them challenges that can’t be solved with the trait you want to showcase. If your character is a warrior, give them a problem that fighting can’t fix. If your character is brilliant, put them in a situation where intelligence isn’t enough. That’s where real character development happens, in the gap between what someone is good at and what the story demands of them.

This applies to any theme, not just empowerment. Whenever the story exists to serve a message rather than the message emerging naturally from the story, the result feels hollow. Let your characters be shaped by their world rather than reshaping the world to fit a single trait.

People Also Ask

What is the biggest mistake authors make when writing a book?
The most common fatal mistake is weak characters. Readers forgive imperfect plots, uneven pacing, and even grammatical errors if they care about the people in the story. Characters without clear motivations, internal conflicts, and genuine growth give readers no reason to keep turning pages.
How important is marketing for a book’s success?
Marketing is as important as the writing itself. The best-written book fails if nobody knows it exists. Bestsellers like Atomic Habits succeeded through consistent, targeted promotion across multiple platforms. Authors need a marketing plan before launch, including Amazon Ads, social media campaigns, email lists, and an author website.
How many revisions does a bestselling book go through?
Most bestsellers go through multiple rounds of revision, often with both the author and a professional editor making passes. The first draft establishes the story. Subsequent drafts refine plot, deepen characters, fix inconsistencies, and improve readability. Setting the manuscript aside for weeks between drafts provides the perspective needed to identify problems.
Should I hire a ghostwriter for my book?
If you have a compelling story or expertise worth sharing but lack the time or writing skill to produce a polished manuscript, a ghostwriter can be a smart investment. Professional ghostwriters capture your voice and vision while bringing narrative expertise to structure, pacing, and character development. Contact a ghostwriting expert to discuss your project.
