Gerçek Kitap Önerisini Nasıl Yazarsınız? Adım Adım Kılavuz

You’ve written a full non-fiction book. It took months, maybe years. You send it to a publisher.

They ignore it.

Why? Because most publishers don’t read finished books from strangers. They read proposals first. A book proposal is a business pitch. It sells your idea before they read a single chapter. Get it right, and you open doors. Get it wrong, and your manuscript joins the pile.

This guide walks you through exactly how to write an English book proposal for non-fiction. You can use the non-fiction book proposal template below to structure your pitch.

Start with the Big Idea (Your Elevator Pitch)

Before you write anything else, answer this in one sentence: What is your book about, and why does it matter now?

This is your opening hook. It goes at the very top of the proposal, often called the Overview. Keep it tight.

Bad example: “My book is about health and wellness and how people can improve their lives.”

Good example: “This book offers a 30-day plan for busy professionals who want to lose weight without spending hours at the gym.”

Publishers scan proposals in seconds. Your first paragraph decides whether they keep reading.

Define Your Target Audience

Do not say “this book is for everyone.” That tells the publisher you haven’t thought about it deeply.

Be specific.

• Who exactly will buy this book?
• What age group?
• What profession?
• What problem do they have that your book solves?

For example: “The primary audience is working women aged 30–50 who have tried dieting but failed because they lack time. Secondary audience: HR managers looking for workplace wellness resources.”

This part shows you understand your market. Publishers love that.

Explain Why You Are the Right Person

This is the About the Author section. Don’t list your entire life story. Focus on what makes you credible.

• Have you written on this topic before?
• Do you have a relevant degree or certification?
• Do you run a blog, podcast, or YouTube channel on the subject?
• Do you have an existing audience?

If you have no platform yet, don’t panic. Show expertise through personal experience. “I lost 40 pounds using this method and have coached 200+ clients to do the same” is stronger than a degree with no practical results.

Analyze the Competition

Publishers want to know your book isn’t just a copy of what’s already out there.

List 3–5 competing books. For each one, write:

• Title and author
• What it does well
• What it misses
• How your book is different

Be honest here. Don’t trash the competition. A publisher may have published one of those books. Instead, show you understand the landscape and your book fills a gap.

Create a Detailed Chapter Outline

This is where most writers fail. A vague outline says “you haven’t finished thinking.” A strong outline shows exactly what the reader will learn, in what order.

Write a one-paragraph summary for each chapter. Then list 3–5 bullet points of key takeaways from that chapter.

Example (for a fitness book):

Chapter 3: The 10-Minute Morning Routine

• Why morning habits stick better than evening ones.
• Three exercises that activate your metabolism.
• How to build the habit in one week.

Publishers read this section carefully. It tells them whether you can actually deliver a full book.

Write a Sample Chapter

Pick your strongest chapter. Write it in full.

This is the proof of your writing ability. If your sample is weak, the entire proposal is weak.

Pay attention to grammar and flow. Short sentences work well. Mix in longer ones for rhythm. Avoid jargon unless your audience expects it. And for non-native English writers: get your sample edited by a native speaker. Mistakes here kill your chances.

Include a Marketing Plan

This section scares many writers. It shouldn’t.

You don’t need to be a marketing guru. Just show you understand how to reach readers.

• Do you have an email list? How many subscribers?
• What social media platforms do you use, and what’s your engagement like?
• Do you have connections with bloggers, podcasters, or influencers in your niche?
• Can you speak at conferences or events?

Publishers take less risk when they see you can help sell the book. Even a small, engaged audience is better than nothing.

The Basic Structure at a Glance

This is a simple schema showing the flow of your proposal. Each section builds on the last.

Common Mistakes to Avoid

I’ve read hundreds of proposals over the years. These are the mistakes that kill them.

• Too long. Keep your proposal between 30 and 50 pages. Anything over 60 is a red flag.
• No clear hook. If your first page doesn’t grab me, the proposal goes in the bin.
• Generic audience. “General readers” isn’t a market.
• Unrealistic sales claims. Saying “I expect to sell 100,000 copies” when you have no platform makes you look naive.
• Sloppy writing. One typo is fine. Ten typos say you don’t respect the process.

Final Tip: Get Feedback Before You Send

Show your proposal to someone who doesn’t know you. Ask them:

• Would you buy this book?
• What confused you?
• What would make you say no?

Their answers will shock you. Use them to improve.

Test Your English Level First

Writing a strong proposal demands clean, persuasive English. One mistake many non-native writers make is sending proposals with grammar issues that distract from their ideas.
