How to write a lead magnet ebook

A lead magnet ebook is a short, free guide you give away in exchange for an email address. A good one makes one specific promise to one kind of reader and keeps it in a few short chapters, each ending with something to do. It draws on your own method and examples, backs up every claim, and closes with one next step toward your paid offer.

Everything hangs on the promise. It tells you who you're writing for, what goes in and what to cut. It's also what a stranger weighs before trading an email address for your guide.

Choose one reader and one promise

Start with the problem your best clients have just before they hire you. Say you coach bookkeepers on running a practice. Before they need you, they need work, so landing their first clients is the problem to solve.

Then write the promise in one sentence: by the last page, this reader will be able to do or have something they can check. A number or a deadline makes it concrete. Narrow is fine. A small promise the guide fully keeps earns more trust than a big one it can't.

From a topic to a promise

BusinessA topicA promise
Bookkeeping coachingGrowing a bookkeeping businessA 30-day plan to land your first three bookkeeping clients
Interior designSmall-space decorating ideasPlan a living room refresh for under $1,000
Career coachingHow to change careersRewrite your resume for a new field in one weekend
Home bakingStarting a cake businessPrice your cakes so every order makes a profit

Each promise names a result the reader can check, and most carry a number or a deadline.

Outline the ebook in the order readers act

Write the chapter headings before any prose, in the order the reader will do the work. Make each chapter one step, and end it with something to do: a checklist, a worksheet, a script or a decision.

Size the guide by reading time, not page count. Marc Brysbaert's 2019 review of 190 studies, published in the Journal of Memory and Language, puts adults' average silent reading speed for English nonfiction at 238 words a minute1. At that pace, a 5,000-word guide of five to eight short chapters takes about 21 minutes, short enough to finish in one sitting.

ExampleOne promise, outlinedAn illustrative example written for this guide

Title: A 30-Day Plan to Land Your First Three Bookkeeping Clients

1. Pick one niche (ends with a niche scorecard)

2. Package a fixed-price cleanup (ends with an offer sheet)

3. List 20 people who could refer you (ends with a contact tracker)

4. Run the first call (ends with a call script)

5. Ask every client for two referrals (ends with the email to send)

Next step: a free 20-minute practice review

  • One reader. First-year bookkeepers, not every small business owner.
  • Steps in order. Each chapter is the next thing to do, so the guide reads as a plan.
  • A tool every time. Every chapter hands the reader something to use the same day.
  • A next step that fits. The free review picks up where chapter 5 leaves off.

If you'd like a form to fill in first, the nonfiction book outline template has room for the promise, the reader and one takeaway per chapter.

Draft it from what you already know

You've probably written half of it already. Pull from client emails, call notes, workshop slides, old blog posts and the questions people ask you every week. Your method and your stories are the parts a reader cannot find anywhere else, so build each chapter around them.

Draft each chapter the way you'd explain it to one client: the step, a sentence on why it matters, an example from your work, then the action. Skip the opening chapter on why the topic matters. Your reader signed up because they already think it does.

Mark gaps instead of guessing

Where a chapter needs a figure or a story you don't have yet, type [ADD: example] and keep writing. Fill every gap before you publish.

Back up every claim

Strangers often meet your work for the first time in a lead magnet, so expect them to check what you say. Link every outside fact to its source, and quote your own numbers only if you can show how you got them.

Client results need the most care. In the US, the FTC's Endorsement Guides say a client's story about a key result will likely be read as what others can generally expect2. If that result isn't typical, say clearly what is. The same section shows that a line like "results not typical" is not enough.

Ask before you use a client's name or story, and keep the details as they happened.

Label made-up examples

If a story is invented or blended from several clients, say so in the text. Never present it as one real client's result.

Design it for screens, not paper

Lead magnet ebooks often go out as PDFs, a format built for print. Nielsen Norman Group, a user experience research firm, summed up 20 years of its PDF research in 2020. Layouts sized for paper, it says, leave readers with tiny type and, on phones, the need to pinch, zoom, squint and scroll3.

The firm's advice is to use a web page instead wherever you can. Your guide can be an unlisted page you link from your welcome email. If you send a PDF, lay it out for a screen: one column, large body text, real headings and working links. Keep the file small so it downloads quickly on mobile data.

An accessible PDF takes more than a straight export from your word processor. The same article says color, contrast, document structure and tags all need deliberate attention.

Deliver it and offer one next step

End the guide with one next step that follows from its last chapter, such as a free call, a workshop or a starter package. Give it one sentence on who it suits and one link. If the offer needs a full pitch, put that on a sales page, not in the guide.

Your signup form makes a promise too. Seth Godin, whose book coined the term permission marketing, writes that to get permission you make a promise, and then that is all you do4. He gave away a third of that book for an email address and never used those addresses again, because follow-ups were not part of the deal. Say on the form what you will send, and how often.

Send the guide the moment someone signs up. A welcome email sequence can deliver it, introduce you and lead to the next step. In the US, the CAN-SPAM Act covers those marketing emails. Each needs your valid postal address and a clear way to opt out5, and the FTC says you must honor an opt-out within 10 business days.

Before you publish your ebook

  • The title states one promise to one reader
  • Each chapter is one step and ends with something to do
  • Every outside fact links to its source
  • Client stories are real and used with permission
  • An unusual result is paired with the typical one
  • It reads easily on a phone
  • It ends with one next step

Have the method in your notes but not the hours to shape it? The tool at the top of this page drafts the whole ebook from your notes and marks a gap wherever a figure or story is missing.

How it works

Start with what the ebook should teach and paste what you already have: notes, an outline, blog posts, a webinar transcript or client handouts. River sets one promise for one reader, plans five to eight short chapters and writes the whole guide into your workspace, built on your method and examples.

It won't invent a client result, a testimonial or a statistic. Outside facts are researched and cited, and anything missing is marked for you to fill. If you leave out the reader, River picks one from your topic and tells you which. Then ask for changes, or for a landing page and a delivery email.

  1. Describe the guide

    Say what it should teach and who it's for, then paste or attach the notes and posts you have.

  2. River plans the chapters

    It sets one promise for one reader, then plans five to eight short chapters that deliver it.

  3. Get the full ebook

    Chapters that each end in a checklist, worksheet or script, plus a summary checklist and your next step.

  4. Fill gaps and promote

    Add the marked figures or stories, ask for edits, then have River write the landing page and delivery email.

What you get

  • A title and subtitle that state the promise, plus three alternative titles to choose from
  • A short introduction saying who the guide is for, what they'll get and how to use it
  • Five to eight short chapters, each ending in a checklist, worksheet, template, script or decision
  • Your own method, examples and voice, drawn from the notes, posts and transcripts you share
  • Outside facts researched and cited, with a marked gap wherever a figure or client example is missing
  • A one-page summary checklist, a closing next step toward your offer and a short author bio

Common questions

What is a lead magnet ebook?

A lead magnet ebook is a free, practical guide that people get by joining your email list, often delivered as a PDF. The strongest ones solve one specific problem for one kind of reader, so the people who download them are the ones most likely to want your paid help next. It doubles as a sample of how you teach.

How long should a lead magnet ebook be?

A lead magnet ebook should be long enough to keep its promise and short enough to finish in one sitting. Adults read nonfiction at about 238 words a minute on average, so 5,000 words take around 21 minutes. River aims for roughly 15 to 25 pages and goes shorter when the promise needs less. Cut any chapter a reader could skip without missing a step.

How do I write a lead magnet ebook with River?

Type what the ebook should teach in the box at the top of this page, add who it's for and the next step you want, and paste or attach your notes. River sets the promise, plans the chapters and writes the full guide into your free River workspace, where you can edit it and fill any marked gaps.

What's the difference between an ebook and a whitepaper?

An ebook teaches, while a whitepaper argues. A lead magnet ebook walks one reader through a problem step by step, in a friendly voice. A whitepaper makes a case to business buyers, usually with research and data, in a more formal tone. If your readers are weighing a purchase for their company, the whitepaper writer fits better.

Does River design the ebook too?

River writes and structures the ebook, but the visual design is up to you. You get the full text in an editable document, with notes on where a diagram, table or screenshot would help. You can download it as a Word file or PDF. For a designed cover and your brand colors, bring the text into the design tool you already use.

Can I sell the ebook on Amazon instead of giving it away?

Yes, but rework it first. Kindle Direct Publishing bars content whose primary purpose is to solicit or advertise6, and it prohibits links to forms that ask for an email address. Make the book worth buying on its own. KDP also requires you to disclose AI-generated text7, including a River draft you edited heavily. The KDP pack drafts the description, keywords and categories.

Is the lead magnet ebook writer free?

Yes, it is free to start. Your ebook opens in a River workspace, where you can edit it, share it or ask River to change it. River can also write its landing page and delivery email. Paid plans add more AI use and access to the most advanced models.
