A book proposal outlines the premise of your book, the target audience, and why it will succeed in the market.

In this article, I’ll guide you through the steps of writing a compelling book proposal for nonfiction writers, from idea to publication.

Introduction to Book Proposals

A book proposal is like the business plan of your book – a document that demonstrates to literary agents and publishing houses that your book has commercial potential. 

The proposal should be concise and compelling, highlighting the unique selling points of your book. But you might need some guidance on how to write a book proposal. 

No problem! That’s why we’re here. 

A book proposal typically consists of several components, including:

• An overview
• An understanding of the proposed audience
• Marketing Plan
• Author bio 
• Chapter summaries
• Sample chapters

Why You Need a Book Proposal

Writing book proposals is essential for nonfiction writers who want to get published. Unlike fiction authors, who can submit a manuscript directly to a publisher, nonfiction authors need a book proposal to showcase their book idea and marketability. 

A well-crafted book proposal can help you secure agents, traditional publishers or help you establish yourself on a self-publishing author platform, increasing your chances of finding an audience.

Components of a Nonfiction Book Proposal

A nonfiction book proposal typically consists of the following components:

The Overview

The overview should be a brief summary of your book, including: 

• the title, 
• subtitle, and 
• premise 

It should also identify the unique selling point of your book, such as why it is different from other competitive titles and how it is similar to previously published books.

Make the publishing house understand where your nonfiction book could resonate with the intended readership. 

Audience

Understanding your intended readership is critical when writing a compelling book proposal. The audience should be well-defined, specific, and up-to-date. 

Are you looking to appeal to stay-at-home moms, work-from-home professionals, entrepreneurs, or college students? This is about recognizing the commercial appeal of your book. 

Include market research that affirms your audience, including the number of your social media followers and sales figures of previous publications in the same genre. Publishers aren’t always looking for tens of thousands of potential readers – but it’s extremely helpful if you can hand them on a plate! 

Marketing Plan

A marketing plan is essential to demonstrate to publishers that you have a strategy to promote your book. The marketing plan should outline the channels you will use to promote your book, such as social media, book signings, and speaking engagements.

Briefly summarize how to intend to reach your test market – explore how publishers or authors marketed comparable titles. 

Author Biography

An author bio is your chance to showcase your expertise and credibility as an author. It should highlight:

• Your qualifications
• Experience related to your book’s topic
• Any previous experience you have with the publishing industry

Chapter Summaries

Chapter summaries should provide a brief overview of each chapter’s content, including the main points and takeaways.

You don’t need to include page numbers or a complete manuscript here – just a brief summary of how you intend to build your forthcoming book. 

Sample Chapters

Sample chapters are an opportunity to showcase your writing style and the quality of your content for your particular book. 

Include the first few chapters – it shows your capability and writing style.
