Picture a founder who has decided to write a book. Ask who it is for, and the answer comes quickly: “anyone who runs a growing company.” It sounds like an advantage. The larger the audience, the larger the potential readership, and the reasoning feels sound.
Once he starts writing, that same breadth works against him. A chapter written for founders, department heads, solo consultants, and first-time managers has to explain itself to all of them, and rarely speaks directly to any of them.
The instinct to widen the audience is easy to understand. But identifying the target audience for your book requires the opposite move: narrowing until you can answer two questions clearly.
Who is this for, and what should change for that person by the end?
A strong idea is only the first test. Once you know it can carry a book, the next question is who needs that book most. We covered the first part in How to Know If Your Book Idea Is Strong Enough Before You Start Writing. Here, the focus is the reader.
Why “Everyone” Is the Most Expensive Answer
The appeal of a broad audience is arithmetic: a larger pool should produce more readers. In practice, a broad audience works the other way — the wider the audience, the less specific everything else in the book has to become. A reader notices within the first few pages whether a book speaks to their exact situation, and one written for everyone rarely does.
That breadth costs the author in three specific places.
- The advice gets more generic. It has to work for a founder, a manager, and a new graduate at the same time.
- The examples lose specificity. Stories chosen to be relatable to everyone rarely feel exact to anyone.
- The book has a weaker role in the author’s business. If it speaks to every professional, it becomes harder to connect it to a particular client, speaking audience, or offer.
A narrower audience gives the author more room to be specific about the problem, the examples, and the advice.
The Three Coordinates of a Real Reader
A useful audience definition should be specific enough to picture one person. Three coordinates help define that reader:
- Who are they, in role and situation?
- Where are they standing right now?
- What question brings them to a book like this?
Role
Start with the reader’s professional position and the texture of their days: what they are responsible for, who they answer to, where the pressure sits. A book for an independent consultant and a book for a VP inside a large company can share a subject and yet need different examples, a different pace, and a different sense of what the reader already knows before opening the book.
Stage
The same role at two points in time is two different readers. A first-time founder raising a seed round and a founder leading a company of more than a hundred people may share the same title but need very different things from a book. Choosing the stage keeps the book from trying to serve beginners and experienced readers at the same time. Choose the moment in the reader’s path where the book does its most useful work.
Problem
Every reader arrives carrying a question: a decision they are weighing, a problem that has resisted their usual methods, a goal that slips just out of reach. Naming that question precisely gives the whole book a job to do. When readers recognize the problem in the opening pages, they know what the book can help them solve.
Role + Stage + Problem = Reader
If you can name all three without falling back on broad labels such as “leaders” or “entrepreneurs,” you are getting close to an audience you can actually write for.
Placed side by side, a defined reader and a broad audience separate at a glance:
| Dimension | A defined reader | A broad audience |
|---|---|---|
| Role | One position, described down to its daily pressures | A whole job family — “leaders,” “professionals” |
| Stage | A single moment in the reader’s path | Every stage of a career at once |
| Problem | One question the reader is weighing right now | A subject the reader might find interesting |
| In one sentence | “Founders of 10–50-person firms who still make every decision” | “Anyone who runs a growing company” |
Finding Your Reader in the Work You’ve Already Done
If you have worked in your field for years, you probably already have evidence of who this book should serve. Look at the people who repeatedly come to you, the problems they bring, and the situations in which your expertise is most useful.
Three sources most often hold it:
- The clients you work with repeatedly. The clients you consistently help most may be strong candidates for the book’s core audience.
- The question that keeps coming up. A problem that surfaces in nearly every discovery conversation is a strong candidate for the problem the book solves.
- The talk that generated the most questions. Look at the audience, the examples they responded to, and what they wanted to discuss afterward.
These patterns give you a better starting point than an imagined reader profile. They show who already finds your expertise useful — and what they consistently need from it.
The Reader and the Buyer Are Sometimes Two Different People
Narrowing to one reader still holds. One refinement matters: in business books, the reader is sometimes a step removed from the buyer — an operations lead reads and passes a decision up to a CEO, or a consultant buys a book in quantity for every new client.
The reader shapes what the book says. The buyer shapes how it sells, gets passed along, and gets used. Most business books that pull their weight are written for the reader and designed with the buyer in mind.
How to Tell When the Reader Is Real
There is a simple way to test it. Write the reader in a single sentence — role, stage, and the question that brings them — then read it aloud to a colleague who knows your field. See whether they can name an actual person who fits — someone you both recognize. If a real person comes to mind immediately, the description is probably specific enough to write toward. If the description still fits hundreds of very different people, it is probably a category rather than a reader.
Return to the founder from the opening. His first answer, “anyone who runs a growing company,” draws the shrug. His second attempt is narrower: “founders of ten-to-fifty-person companies who are still making every decision themselves and can feel that habit starting to limit the company’s growth.” That sentence names a role, a stage, and a problem. A colleague can point to three such founders by name, and can say what each of them would want the book to help them do.
Where the Reader Fits in the Larger Design
Identifying the reader belongs at the very start of a book project, in the same stage that shapes the concept. Reader definition and concept development happen together: the reader determines what the book needs to accomplish, while the concept determines how the book will do it. Why Your Book Concept Matters More Than Your Writing takes up that second half of the work.
This is why the AVELaunch process names the reader before a single chapter is drafted — every later decision answers to that one person. A Discovery Sprint tests that reader against four real decisions:
- A working title that has to name their problem, not just the book’s topic
- A chapter structure that has to follow their exact path, not a generic outline
- A synopsis that has to hold their question from the first page to the last
- A sample chapter that has to sound like it’s speaking to them, not to a category
In two weeks, a phrase like “anyone who leads a team” turns into someone the author can picture, describe, and write toward.
Ready to Name Your Reader?
Before you draft a chapter, put your reader in one sentence: their role, their stage, and the problem that brought them to a book like this. Read it back — if it still fits hundreds of different people, the narrowing hasn’t happened yet.
That narrowing is worth doing before the writing begins. At AVELaunch, it happens during the Discovery Sprint, alongside the positioning and concept work that gives the rest of the book its direction.
and find the person your book is for.
