How to Choose a Great Book Topic (That Actually Grows Your Business)

Jul 02, 2025

If you’ve been dreaming of writing a book but feel stuck at the very first step—choosing a topic—you’re not alone.

Many coaches, consultants, and creators have a message burning inside them… but too many ideas floating around in their heads. The result? Paralysis. Procrastination. Another year goes by, and the book remains unwritten.

In Seven Day Author, I show you how to go from blank page to published book in a single week. But here’s the truth: everything starts with choosing the right topic. Not just one that feels inspiring—but one that builds your credibility, attracts the right clients, and aligns with your business goals.

Let’s break it down.


1. Start with Your Expertise, Not Just Your Interests

A good book topic isn’t just something you find fascinating—it’s something you can speak about confidently, with real-world experience or results to back it up. Think about:

  • What do people already ask you for advice on?

  • What results do you consistently help your clients achieve?

  • What frameworks or tools do you use that could be turned into a method?

🧠 Example: A leadership coach might write about “How to Lead When You're the Only Woman in the Room,” turning her lived experience into a high-impact, focused topic.


2. Use the Authority Filter

Ask yourself: “What do I want to be known for one year from now?” Your book should help position you as an expert in your niche.

To choose wisely, score your ideas based on:

  • Alignment with your current or upcoming offers

  • Your passion and depth of knowledge

  • Market demand (yes, people need to actually want to read it)

📊 Pro tip: If it doesn’t connect to your business or audience, save it for a personal blog. Your book is a growth asset—not just a journal.


3. Validate with Real Data (Not Just a Gut Feeling)

Before you write, make sure your topic has traction.

✅ Check Amazon: Are there books in your niche with strong reviews and rankings?
✅ Use Google Trends: Are people searching for this topic?
✅ Ask ChatGPT: “Summarize the top pain points people have around [your topic].”

You don’t need a totally original idea—you need a focused, useful one that solves a real problem.


4. Niche Down to Stand Out

Broad books blend in. Specific books sell.

Instead of writing “How to Start a Business,” write “How to Start a Freelance Design Business While Working Full-Time.” You’re not shrinking your audience—you’re increasing clarity and trust.

🎯 Your reader should say: “This is exactly for me.”


5. Don't Wait for the “Perfect” Idea

Spoiler alert: It doesn’t exist.

A book that’s 80% right and actually finished will beat a perfect idea that never leaves your Google Doc. That’s why the Seven Day Author method works—because it gives you permission to move forward with a smart idea and refine it as you go.
