eBooks are a fantastic way to generate extra income, but choosing the right topic can be challenging. The best eBook niches often focus on universal problems like health, finances, and relationships. In this guide, we’ve highlighted some top niches to help you decide what to write about.
The eBook market is growing fast, offering great opportunities for authors and entrepreneurs. But with so many topics, how do you pick the right one? In this guide, we’ll explore the seven most profitable eBook niches for 2025 and share tips on choosing a niche that fits both your passion and market demand.
Whether you’re new to writing or have some experience, this guide will help you find a topic that sells.
How to Find eBook Niches?
While many entrepreneurs find selling digital books accessible and profitable, it’s easy to get lost in the vast array of topics you can write about!
You’ve probably heard about the importance of “niching down”. While it’s true that, especially in the beginning, you should avoid topics with high competition, obscure topics might not be the best niche for you.
The most profitable ebook niches are the “evergreen” ones — topics that people are always interested in and will continue to seek out over time.
Think about it: everyone wants to feel healthy. Like it or not, humans are social beings — we need strong, fulfilling relationships. We all need to eat, and everyone has bills to pay. That’s how the world works, and it’s unlikely to change any time soon.
So, how can you identify these topics? Fortunately, there are a few (free!) tools you can use:
Google Trends
Google Trends is a tool from Google that shows us what people have been searching for. It provides data from years past, which helps you differentiate between short-lived trends and topics that will continue to sell in the coming years.
(For example, while some health trends come and go, searches for “diabetes” have remained stable over the past few years, indicating it’s a reliable niche.)
Amazon
As the world’s largest book retailer, Amazon dominates the digital book market. In fact, 60% of all eBook sales happen on Amazon, so what you see in their “Most Sold” section offers valuable insights into reader demand.
Pay close attention to this section because it reflects what readers are buying not only on Amazon but across other eBook platforms. However, don’t just focus on the top-rated books — lower-rated books can provide just as much value by highlighting what to avoid as an self-publishing author.
The Top 7 Most Profitable eBook Niches
We’ve selected some of the top selling eBook niches for you. Keep reading to discover them and get a few tips on how to succeed within these markets!
1. Personal Development and Self-Help
Mental health is one of the defining issues of our time.
It’s a double-edged sword: while the demands of modern life can often challenge our well-being, if we want to thrive in today’s world, we need to be on our most aware, most productive level.
The range of topics within personal development is vast. You could write about boosting productivity when working from home, building self-esteem, or even offering guidance on parenting. The opportunities are endless.
Tip: For your first eBook, choose a specific issue to tackle and offer straightforward, practical advice. Even if you don’t have a formal background in psychology, diving into credible research will help you provide valuable, accurate insights.
Most self-help eBooks aim to solve real-life problems, and the more significant the issue, the more people will look for solutions.
2. Relationships
This has been a trending topic since forever. It was popular 50 years ago, and from the looks of it, the next generation will still be dealing with the same challenges.
After all, which girl hasn’t dreamed of finding her prince charming? How many young men feel nervous about approaching women? And once you’re married — well, dealing with another person every day can be quite the challenge.
These topics bring both joy and frustration into people’s lives — hence why it’s one of the best ebook niches to write about. The beauty of writing about relationships is that you can focus on very specific issues, and no matter how narrow the subject, there will always be plenty of people interested in reading your eBook.
3. Health and Wellness
Few topics are as evergreen as health. Alongside relationships and money, it’s one of life’s biggest concerns.
How you feel physically is closely tied to your mental state. Fatigue or physical pain can easily affect your mood, which in turn impacts your work and relationships.
From general health to nutrition or specific conditions (like living with autoimmune diseases), there’s a wide range of topics your eBook can cover.
You don’t necessarily need a degree to write about health — people tend to connect more with personal experiences than raw data. For example, an eBook titled “How I Beat Type 2 Diabetes Without Eating Salad” might attract more attention than a typical health manual.
However, if you do decide to tackle health topics, make sure to back your claims with scientific research for credibility.
4. Business and Entrepreneurship
This is likely the most popular non-fiction category — and for good reason. The high competition reflects the endless demand for business advice.
It’s also a great niche for beginner entrepreneurs. As you learn the ins and outs of building your online business, why not compile your notes into an eBook and earn a little extra income as you go?
To avoid creating a generic eBook, consider including useful tools and resources — such as a business planner or step-by-step guides. It’s also a smart idea to add case studies of successful entrepreneurs who’ve thrived using the strategies you’re teaching.
5. Children’s Books
One thing is certain — children are being born every day, all over the world. And with that, parents are increasingly focused on their children’s well-being and development.
As a result, the market for children’s eBooks is growing. With the latest Kindle devices supporting illustrated books and digital gadgets becoming more affordable, it’s no surprise that this niche is expanding.
(Plus, digital books have the added bonus — parents don’t have to worry about their kids tearing the pages! Isn’t that great?)
For beginner writers, it’s best to focus on addressing parents’ key concerns. Consider creating short stories for children who are just starting to read, or fun books about topics like religion and good manners.
Write what parents would like their kids to read, and the sales will come!
6. Cooking
Let’s face it — eating is one of life’s greatest pleasures.
But food is more than just sustenance. For many, it’s a source of comfort on tough days or a way to show love to others.
Given how vast the cooking niche is, it’s important to be specific with your eBook’s title and topic. Our suggestion? Focus on the emotions that food evokes.
For instance, instead of a generic title like “Cake Recipes,” why not go with “Comfort Food for Rainy Mornings”? Or instead of “Mediterranean Recipes,” try “At-Home Date Night Dishes.”
Get creative, and the profits will follow!
What About Fiction?
If you’re aiming to make money online, non-fiction might seem like the easier route. It’s practical, straightforward, and quicker to produce. But here’s the thing — fiction still dominates eBook sales.
Why? Fiction eBooks are often cheaper than printed books, and they provide readers with a much-needed escape from reality. After all, who doesn’t love getting lost in a great story?
Let’s take a look at the best-selling fiction genres:
- Romance: sure, information is important, but sometimes people just want to unwind with a love story. Romantic novels consistently top the charts because they offer readers that much-needed emotional escape.
- Horror and Suspense: if you’re good at building tension and keeping readers on the edge of their seats, horror or suspense might be a lucrative source of income for you!
- Thriller: thrillers are all about high-stakes crime and mystery. They keep readers hooked with fast-paced plots and constant twists, making them a favorite for anyone who craves a bit of adrenaline.
Interestingly, social media shows that a lot of readers — especially women — enjoy a mix of these genres. And speaking of social media…
Ever Heard of BookTok?
If you’re thinking about writing fiction, social media is your best friend. Communities like BookTok and Bookstagram are full of readers and content creators sharing their favorite books. A lot of indie authors have gained thousands of fans just by being mentioned on these platforms. It’s also a treasure trove for discovering new trends and story ideas.
Humans have always used stories to make sense of the world. So, it’s no surprise that the latest trends in fiction feature diverse characters — not just in terms of ethnicity, but also neurodiversity — and touch on relevant social and political issues. Readers today want stories that reflect the world they live in.
How to Find Your Perfect eBook Niche
The best eBook niche for you is somewhere between what you’re passionate about, what you can speak on with authority, and what’s actually profitable. Let’s break this process down into a few simple steps:
- Look at What’s Already Selling: start by exploring what’s working in the market — not just on Amazon Kindle, but across other eBook platforms too. Pay attention to the best-sellers and trending categories.
- Think About Topics That Interest You: among those trending topics, is there something you’re already familiar with or eager to learn more about? The more genuine your interest, the easier it will be to write with enthusiasm.
- Do Your Market Research: dive into the latest trends. What are the best-selling books in your potential niche? Check out social media channels that relate to the topics you’re considering. What are people talking about? What matters to them right now?
- Analyze Your Audience: look at comments on social media and book reviews (both positive and negative) related to your niche. Explore all kinds of content, even if it’s from creators who aren’t authors. This will give you insight into not only the topics people care about but also the keywords you should use in your eBook and marketing efforts.
Passion vs. Profit
Of course, you want your eBook to make money. But diving into a niche just because it looks profitable on the surface isn’t always the best approach.
In competitive markets, success isn’t just about content. People are more likely to buy from an author they trust. An eBook written by someone people admire and can identify with it will often outsell a higher-quality eBook from an unknown writer.
And choosing profit over passion isn’t the only mistake people make when picking a niche…
Common Mistakes to Avoid When Choosing an eBook Niche
- Choosing the wrong niche: make sure the topic resonates with both you and your audience.
- Focusing only on what matters to you: your eBook needs to solve a problem or address an issue that your audience cares about, not just what interests you.
- Doing it just for sales: readers can sense when something lacks authenticity.
- Not niching enough: if your topic is too broad, it will be harder to stand out.
- Niching too much: make sure your niche isn’t so specific that only a handful of people are interested.
Creating an eBook That Sells
Picking the right niche is the foundation of a successful eBook. When you find that sweet spot between what you love, what you know, and what sells, you’re more likely to engage readers and stand out in the market.
