Determine What Problem Your Nonfiction Book Solves

When it comes to nonfiction writing, it's common for beginning ideas to be a bit vague. It's easy to have a general concept in mind, but to truly make your book a success, you need to do market research to ensure there's an audience for your work. 

This research will help you narrow down your focus and identify the specific problem your book will solve.

In most cases, nonfiction books are written to solve a specific problem. Whether it's a how-to guide on a particular topic, or a self-help book addressing a certain issue, these types of books are meant to provide readers with valuable information that can help them in some way. 

Side note: there are some genres, such as history books, creative nonfiction, or memoirs, that don't quite fit into this mold. But even in these cases, it's still important to understand why people want to read it.

When doing market research, it's important to answer the five W's of your book: the who, what, where, when, and why. 

By answering these questions, you'll be able to identify your niche and craft a book that truly resonates with readers.

Validate Your Book Idea

Before you completely narrow down your story or topic, you need to know if it's a good idea or not. To do this, you need to run through four steps:

• Step 1: Learn if and how many people search for your book idea
• Step 2: Learn if the idea is profitable during the book topic validation process
• Step 3: Discover how hard the competition is for your book
• Step 4: Rinse and repeat

If you find your book topic is not profitable, you can still write it. But if that's the case, you will have to resort to different marketing tactics. You will need to focus on finding the right market somewhere other than Amazon, and getting them interested in reading your book.

Determine Your Audience

When it comes to market research for your book, the most important part is understanding your audience. Without a clear understanding of who you're writing for, it will be difficult to create a book that truly resonates with readers. Counterintuitively, you want to narrow down your audience as much as possible. 

One of the best ways to narrow down your audience is by creating a customer avatar. This is a single person that represents your ideal reader. 

The more specific you can make this person, the better. 

It's important to think about things like their gender, age, background, education level, family situation, and even how much money they make. 

The more specific you can get, the more you'll understand about the kinds of problems they're facing, and how your book can help them.

Having a customer avatar in mind can help you make important decisions about your book, such as what types of information to include, what tone to use, and even what types of marketing to do. 

It also helps to think of your customer avatar when you are writing as well so you are writing with a specific person in mind and that will help you to keep your writing more focused. 

You want to make sure you are covering all the subjects thoroughly in your nonfiction book outline, and nothing is lost in translation. Here are some ideas to help.

Brainstorm Ideas

Once you have a clear understanding of your target audience and the problem your book will solve, it's time to start brainstorming ideas. If you already know what your book is about, this is the time to think about how to structure your book and what to include in it. 

If you're still not sure what your book is about, this is the time to explore different possibilities.

When brainstorming ideas, it's important not to hold back. Write down everything that comes to mind, even if it doesn't seem like a good fit at first. 

To help generate ideas, try brainstorming with a group of people, whether it's friends, family or other nonfiction writers. They may have insights you haven’t considered and the exchange of thoughts can be very productive. Also, you could explore other books in your niche and look for inspiration, or research the latest trends and best practices in your niche.

Ultimately, don't be afraid to experiment and try out different things. Brainstorming is a creative process and the more ideas you have to work with, the better your final book will be.

Research

After brainstorming ideas, it's time to dive into research. Research is the best way to truly understand what your book should talk about.

If you find that no one has written about your topic before, it might be a sign that the topic may not be as helpful as you think. So, it's important to be open to the possibility of changing the topic or pivoting in a different direction.

The research process should involve looking through a variety of sources such as books written by others, online articles, podcasts and YouTube videos, interviews, and anything else that may be relevant to your topic. This will give you a good idea of what to cover, but also what gaps in knowledge still exist.

As you research, make sure to gather all unique pieces of data into your notes. Organize the information by topic or subtopic, and make sure to include the source of each piece of information. This will be useful later when you're writing your book and need to cite your sources or refer back to specific information.

Research is a crucial step in the book-writing process, and the more time you spend doing it, the more valuable your book will be. 

It will help you to understand your topic more deeply and help you to better serve your readers. Remember, research is not just to back your claims but to improve the credibility of your book.

Use Nonfiction Story Structures

I often talk about story structure when it comes to fiction, but nonfiction books can benefit from using story structures as well. There are many different types of nonfiction story structures you can use, but here are a few examples to get you started.

• Manipulating Time: With this structure, your story starts in the middle, and shows how you got there in flashback-type sequences. This is great if you're using your own story or something from one of your clients. It allows you to show how your protagonist got to where they are, using the principles you outlined in the book.
• Hook, Story, Offer: This is a great framework from Russell Brunson that I like to use. It consists of three different steps: Hook, which is the thing that gets your readers interested; Story, which is the thing that connects your readers with the emotional truths you're trying to convey; and Offer, where you present the solution to the problem you outlined in your story.
• Circular Structure: Similar to manipulating time, this structure starts at the end, and shows how you got there.
• Parallel Structure: With this structure, you might have two or more stories that you are weaving together. They might seem separate at first, but you tie them together by the end. This is a great way of interweaving your personal story with the principles in your nonfiction book.

Using nonfiction story structures can be a great way to engage your readers and make your book more compelling. By using one of these structures, you can help your readers understand and connect with the information you're presenting in a more meaningful way.

Put it All Together

Once you have your structure in place and your notes organized, it's time to weave it all together into something coherent. 

This can be a challenging step, as you'll need to take all the information you've gathered and figure out how to present it in a logical and easy-to-understand way. 

It's important to be selective with the information you include, as you'll likely have more than you can include in your book. This means that some things may need to be left out, as hard as that may be.

Once you have that all fleshed out and ready to go, it’s time to move on to the next step…

Determine the Best Writing Software

Choose the best book writing software for individual project, consider software like Atticus, Scrivener, Ulysses and Microsoft word or Google Docs.

Atticus

Atticus is the best book writing software for overall capability, including tracking software and formatting. It costs $147 as a one-time fee and works on multiple platforms. 

Plus, it is optimized for nonfiction, with certain features that make the nonfiction process SOOOOO much easier, including:

• Endnote and Footnotes (the only budget-friendly tool to do the latter)
• H2 – H6 Headers
• Callout boxes
• Hanging indents

It is my #1 recommendation for authors who want to write and format books of any kind!

Scrivener

Scrivener is the next best option for organization and customization, but it has a steep learning curve and costs $49 (one-time) for Mac or Windows. $19.99 for iOS devices and reduced pricing of $41.65 is available for “students & academics”.

Use Kindlepreneur’s unique discount code (KINDLEPRENEUR) to get 20% OFF your purchase.

• Download Scrivener 3 for Mac
• Download Scrivener 1 for Windows, which is on par with Scrivener 2 for Mac (update coming in 2021)
• Download Scrivener 1 for iOS, which is also on par with Scrivener 2 on Mac (a handy tool for on-the-go writing with an iPad or iPhone)

Ulysses

Ulysses is a customizable and sleek book writing software that syncs automatically and has a drag-and-drop functionality, but only works on Apple products and costs $5.99/month or $49.99/year, but with a free 2-week trial. 

Microsoft Word

Microsoft Word is industry standard for word processing, but not ideal for novel writing, often used because of its ubiquity, but it is cumbersome for writing a book, and costs $139.99 as a one-time purchase or $6.99/month for a Microsoft 365 subscription.

Write the Book Fast

When it comes to nonfiction and fiction alike, I firmly believe that getting the book out as fast as possible is the best way to go. Writing fast allows you to get the first draft on the table and start the editing process. 

Important: The goal at this stage is not to create a perfect product, but simply to get the words down so you can work with them later.

One of the main advantages of writing quickly is that it helps to overcome writer's block and other forms of procrastination. When you're not focusing on making everything perfect, it's easier to simply get words down on the page. 

It's also useful to remember that the first draft is not meant to be perfect, it's meant to be a starting point, it's where you will put down the ideas that you want to explore further, and decide which direction you want to take.

Some quick tips to write fast include

• Set good goals
• Work in manageable chunks
• Develop writing habits
• Right at the same time everyday
• Use a timer
• Try dictation

I have a whole list of other ways to write faster in this article.

Use Storytelling

Storytelling is often seen as something that is only relevant to fiction writing, but it's equally important in nonfiction. Stories allow you to draw readers in and make them emotionally connected with your subject matter.

There are many ways to incorporate stories into your nonfiction book. You can mine stories from your own life, the lives of your clients, history, or even current events. 

The key is to find stories that are relevant to the topic of your book and that will help to illustrate the points you're trying to make.

Keep the Writing Simple

For nonfiction, it's important to keep the language simple and easy to understand. Unless you are speaking to a highly educated audience, this will almost always be the case. 

This is because nonfiction books often have the goal of conveying information to a wide audience, which means that the language must be accessible to a general reader.

Using simple and easy-to-understand language not only makes your book more accessible to a wider audience, but it also makes it more likely that your readers will retain the information you're trying to convey. 

Avoid using jargon and technical terms that might not be familiar to your general audience. Instead, explain them in simple terms or provide definitions. 

The more complex your topic, the more you want to be able to explain that topic in simple terms.

Self-edit the Book

Let's be honest, self-editing is not everyone's favorite part of the writing process. However, it is an important step that should not be overlooked. Before you send your work to beta readers or an editor, it's a good idea to have at least one self-edit. 

This will give you an opportunity to catch any errors and make sure your ideas flow well, your arguments are tight and the book feels coherent.

The key is to approach self-editing with an open mind and a critical eye. Take the time to read through your work carefully and consider whether each sentence and paragraph adds value to the book. Look for ways to tighten up the writing, eliminate redundancy and make sure that the book is clear and easy to understand. 

Fact Check Everything

In today's age of misinformation, fact checking is more important than ever. It's crucial that the information in your nonfiction book is accurate and reliable, otherwise it risks losing credibility with your readers. 

The good news is that if you did your research well, and documented everything, this step will be greatly simplified. You should have sources and citations to back up every claim you make in your book. 

By double-checking these sources and making sure that the information is still accurate, you'll ensure that your book is reliable and trustworthy.

Send to Editors

After you've given your manuscript a thorough self-edit, it's time to send it to an editor. An editor is one of your most important resources when it comes to producing a polished and professional book. 

They can provide valuable feedback and make suggestions that will help to improve the overall quality of your manuscript.

It's important to keep in mind that editing can be one of the more expensive parts of the book writing process. However, investing in an editor's expertise is well worth the effort. 

An editor can help you to turn your manuscript into a polished and professional book that will stand out among the competition.

Send to Beta Readers

Once you have a decent product, it's time to send it out to beta readers. Beta readers are a valuable resource that can help you to identify problems you might not have thought of. 

Beta readers can also help you to understand if the stories you used in your manuscript worked and if any of them were confusing. They will give you an idea of how the general audience might receive your work. They can point out if certain parts of the manuscript are too complex or if certain sections don't flow well.

This feedback is essential to help you to make necessary adjustments before your book is ready for publication.

The best way to format your nonfiction book is using Atticus, the best formatting tool for nonfiction, given that it has multiple nonfiction-specific features that other formatting tools don't have.

Plus, it's way cheaper and easier to use than any of the other formatting tools out there.

For example, here are some of the nonfiction-specific features that you might want to use:

Subheadings

While most formatting tools have only one size of heading, Atticus has the ability to create multiple levels of headings, meaning you can have main headings, then subheadings underneath those headings, etc. Here's what that looks like:

Additionally, you can customize the size and style of each heading type, which actually means that fiction authors can make use of the headings as well.

By selecting a specific style font, you could create the illusion of a hand-written note or a text that you could use insert into your text. So headings are not just for nonfiction authors!

Here's the what the heading formatting looks like in Atticus:

Footnotes/Endnotes

Until Atticus came along, there wasn't any affordable and easy to use program that provided footnotes in books. But Atticus can!

With Atticus, you can easily add footnotes that will appear at the bottom of each page in your print edition (note: ebook editions, by necessity, default to endnotes).

In addition to footnotes, Atticus also lets you select endnotes, and let's you specify whether you want your endnotes to appear at the end of the book, or the end of each chapter.

Hanging Indents

Hanging indents are an essential piece of formatting for authors who have a lot of references. A hanging indent is used when you need to list your sources and create a bibliography.

In other words, this is an essential piece of the puzzle for any nonfiction author who needs to list their sources.

Callout Boxes

Last but not least, Atticus has Callout Boxes!

These are honestly some of my favorites.

Atticus lets you add a callout box to any selection of text, and it will show up with that callout box in ebook or in print.

You can completely customize the look of your callout boxes, as seen here:

And then, once you've got something like that, you can preview it in Atticus' device previewer, where it might look a little something like this:

Research Your Title and Subtitle

When it comes to writing a nonfiction book, finding the right title and subtitle is crucial. This is because a well-crafted title and subtitle can help to attract readers and increase the visibility of your book.

One effective way to determine your title and subtitle is by doing keyword research.

Keyword research can be done by extensively crawling through Amazon's listings. This can help you to understand what people are searching for, and what kind of titles and subtitles are most effective. 

Pro Tip: The key is to figure out what people are searching for, and use this information to choose a title and subtitle that will resonate with your target audience.

Unfortunately, manual searches can be tedious when done manually. However, there's a tool out there called Publisher Rocket that will automate this process and make it faster and easier. 

This tool can help you to analyze your competition, uncover the best keywords, and optimize your title and subtitle for maximum visibility.

Publish Your Nonfiction Book

After all the hard work of researching, writing, editing and fact-checking, it's finally time to publish your book. It can be a daunting process, but with the right guidance, it can be done seamlessly. 

If you're planning to publish your book on Amazon, I have an article that can be extremely helpful. 

It provides an in-depth guide on how to publish your book on Amazon, detailing the different options and services available, and how to use them.

Market Your Book to Your Audience

When you publish your book, make sure you format your book correctly, nail your back cover blurb, have a stellar book cover (traditional publishers will usually pay for this), and properly organize the front matter and back matter.

Hopefully, you know that you have to start marketing your book long before it hits shelves and the online marketplace.
