How to Write a Market Analysis for a Book Proposal

The market analysis in a book proposal answers the question a publisher cares about most: who will buy this book, and how do you know? It is where you prove an audience exists, size that audience credibly, and position your book among the titles those readers already buy. New authors often treat this section as a formality and fill it with vague claims. Editors read it closely, because it is the part of the proposal that most directly predicts sales. This guide covers how to define your audience, size the market with real numbers, write a competitive title analysis that works, and avoid the mistakes that sink this section.

This is a deep dive on one section of the proposal. For the whole document and how the pieces fit together, see Editor World's guides to writing a non-fiction book proposal and to book proposal components.

Quick Answer: How Do You Write a Market Analysis?

Write a market analysis in three parts. First, define your target audience in specific terms: who they are, what they already read, and why they need this book. Second, size that audience with real, verifiable numbers: the membership of relevant organizations, the size of online communities, category sales figures, search interest, or the readership of publications that cover the topic. Third, write a competitive title analysis that lists five to eight recent, successful comparable books and, for each, acknowledges what it does well and explains how yours differs. The goal is to prove a real, reachable audience already buys books like yours, and that yours fills a gap those books leave open. Use concrete evidence throughout; vague claims about broad appeal weaken the whole section.

What a Market Analysis Actually Proves

A publisher takes on financial risk with every book. The market analysis is where you reduce that perceived risk by showing the audience is real and reachable. It does two connected jobs. It proves demand exists, and it proves you understand the landscape your book would enter. An acquiring editor uses this section to make the case internally to sales and marketing, so the stronger and more specific it is, the easier you make it for someone inside the house to champion your book.

The failure mode is generality. "This book will appeal to anyone interested in health" is not a market analysis. It names no specific audience, offers no evidence, and gives the editor nothing to work with. A strong analysis is concrete at every step: a defined reader, a sized audience, and named competing titles. Specificity is what separates a section that helps from one that just fills space.

Defining Your Target Audience

Start by describing your primary reader in real terms. Not "everyone," but the specific person who will pick this book off the shelf. What is their situation? What problem are they trying to solve, or what interest are they trying to feed? What do they already read on the topic? A clear picture of one real reader is more persuasive than a claim of universal appeal.

Then identify secondary audiences where they genuinely exist. A book on managing a small team might have a primary audience of new managers and a secondary audience of experienced managers moving into larger roles. Name these honestly. Inventing secondary audiences to inflate the numbers is transparent and undercuts your credibility. The aim is a truthful, specific map of who this book is for.

Resist the instinct to widen the audience to make it look bigger. Counterintuitively, a narrow, well-defined audience is more convincing than a broad, vague one. Publishers know that books aimed at "everyone" tend to reach no one. A sharply defined reader signals that you know your book and can help reach the people most likely to buy it.

Sizing the Market With Real Numbers

Once the audience is defined, show how large and reachable it is using evidence rather than assertion. This is the part authors most often skip, and it is the part that most strengthens the section. The specific sources depend on your topic, but the reliable ones include:

  • Membership numbers. Professional associations, hobby organizations, and interest groups often publish membership figures that directly indicate audience size.
  • Online community size. The size of relevant forums, subreddits, groups, and followings around your topic shows an engaged, reachable audience.
  • Category sales data. Evidence that books in your category sell well demonstrates a proven buying audience, not just an interested one.
  • Search interest. Consistent search volume for your topic shows active, ongoing demand for information about it.
  • Publication readership. Magazines, newsletters, and sites that cover your subject, and their audience sizes, show that media already serves this readership.
  • Event and course attendance. Conferences, workshops, and courses on your topic prove people invest time and money in the subject.

Use these figures to build a picture, not to claim every one of those people will buy the book. The point is to show the audience is large enough and reachable enough to support a title. A few well-chosen, verifiable numbers are far stronger than a pile of vague estimates.

Writing the Competitive Title Analysis

The competitive title analysis, or comp section, lists the books your audience already buys and positions yours among them. It usually covers five to eight titles. Its purpose is often misunderstood. The comps are not competition to be dismissed; they are proof of a market. Books like yours selling well is the best evidence that yours can sell too.

Choose comps that are recent, usually published within the last five years, reasonably successful, and genuinely similar to your book in audience and approach. Recency matters because it shows the market is active now. Success matters because a comp that sold poorly undercuts your case. Similarity matters because a comp that is not actually like your book proves nothing about your audience. Avoid two common errors: comparing your book to a runaway mega-bestseller, which reads as naive, and claiming no comparable titles exist, which signals no proven market rather than a uniquely original book.

How to Write a Single Comp Entry

Each comp entry follows a simple, effective pattern. Give the title, author, publisher, and year, then a few sentences that do two things: acknowledge what the book does well, and explain how yours differs or what it adds. The structure matters because it positions your book as related but distinct.

The difference you name should be real and specific. "Mine is better" is not positioning. "That book covers the strategy in depth but assumes an experienced audience; mine addresses the same strategy for first-time founders with no background" is positioning. Whether the difference is audience, angle, scope, format, or recency, name it concretely. Done well across five to eight titles, this builds a clear picture of exactly where your book sits and why there is room for it.

Aim for a consistent length per entry, roughly a short paragraph, so the section reads as a considered analysis rather than a list. The cumulative effect should be that an editor finishes the comp section understanding your book's place in the market without you having to state it outright.

Common Market Analysis Mistakes

Most weak market analyses fail in recognizable ways. Check yours against these before you submit:

  • Claiming a universal audience. "Everyone will want this" reads as no defined audience at all. Name a specific reader.
  • Numbers-free assertions. Saying the audience is large without evidence is the most common weakness. Show verifiable figures.
  • No comparable titles. Claiming nothing compares signals no market, not originality. Find real comps.
  • Mega-bestseller comps. Comparing your debut to a record-breaking hit reads as unrealistic. Choose solid, credible successes.
  • Dismissing the competition. Treating comps as rivals to knock down misses the point. Use them as proof of demand.
  • Vague positioning. "Mine is better" is not a difference. Name the specific gap your book fills.

Frequently Asked Questions About Book Proposal Market Analysis

What is a market analysis in a book proposal?

A market analysis is the section of a non-fiction book proposal that proves an audience exists for the book, sizes that audience with evidence, and positions the book among the titles those readers already buy. It answers the central question a publisher has: who will buy this book, and how do you know? A strong market analysis defines a specific target reader, supports the size of the audience with verifiable numbers like organization membership and category sales, and includes a competitive title analysis of recent comparable books. It's one of the sections editors read most closely, because it most directly predicts sales.

How do I define the target audience for my book?

Define the target audience by describing the specific reader who'll pick the book off the shelf, rather than claiming universal appeal. Identify their situation, the problem they're trying to solve or the interest they're trying to feed, and what they already read on the topic. Name secondary audiences only where they genuinely exist, and don't invent them to inflate the numbers. A narrow, well-defined audience is more persuasive than a broad, vague one, because books aimed at everyone tend to reach no one. A sharply defined reader signals that you understand the book and can help reach its buyers.

How do I estimate the size of the market for my book?

Estimate market size using real, verifiable evidence rather than assertion. Useful sources include the membership numbers of relevant professional associations and interest groups, the size of online communities and followings around the topic, category sales data showing that similar books sell, search interest indicating ongoing demand, the readership of publications that cover the subject, and attendance at events and courses. Use these figures to show the audience is large enough and reachable enough to support a book, without claiming everyone in it will buy. A few well-chosen, verifiable numbers are far stronger than vague estimates.

What are comp titles and how many should I include?

Comp titles, short for comparable titles, are recently published books similar to your book in audience and approach. A competitive title analysis usually includes five to eight comps. They're not competition to be dismissed but proof that a market exists, since books like yours selling well is strong evidence that yours can sell too. Choose comps that are recent, usually within the last five years, reasonably successful, and genuinely similar. Avoid comparing your book to a runaway mega-bestseller, which reads as naive, and avoid claiming no comparable titles exist, which signals no proven market.

How do I write a single comp title entry?

Write each comp entry by giving the title, author, publisher, and year, followed by a few sentences that acknowledge what the book does well and explain how yours differs or what it adds. The difference should be real and specific, whether it's audience, angle, scope, format, or recency. A concrete distinction, like addressing the same topic for a different level of reader, is positioning, while a vague claim that your book is simply better isn't. Keeping each entry to a consistent short paragraph makes the section read as a considered analysis rather than a list.

What is the most common mistake in a book proposal market analysis?

The most common mistake is generality: claiming a universal audience and offering no evidence of size. Statements like saying the book will appeal to anyone interested in a broad topic name no specific reader and give the editor nothing to work with. Other frequent mistakes include numbers-free assertions about audience size, claiming no comparable titles exist, comparing a debut to a mega-bestseller, treating comps as rivals to dismiss rather than proof of demand, and offering vague positioning that says the book is better without naming a specific gap it fills. Concrete evidence at every step is what makes the section work.

Should the market analysis section be professionally edited?

It benefits from professional editing along with the rest of the proposal. The market analysis has to read as clearly and confidently as the overview and sample chapters, and it sits within a document a publisher judges as a whole. A focused editorial pass tightens the argument, removes the vague claims that weaken a market case, and makes sure the section presents its evidence in the strongest form. Because the market analysis is one of the sections an acquiring editor weighs most heavily, clear and well-supported writing here directly strengthens the case for the book.
