Introduction: Why Genre Matters
The genre you choose signals to your target audience what kind of book they are looking at and who it is intended for. Even hybrid books need a primary genre, so they can be discovered by the right audience. The self-publishing market is enormous: around 300 million self-published books are sold worldwide every year, generating approximately $1.25 billion in revenue. More than 50% of books are purchased online, and 90% of self-publishers use Amazon KDP. Standing out in such a crowded marketplace is difficult. Successful self-publishers emphasize that no book “fits no genre” — a clear place on the shelf is essential for visibility and effective audience targeting.
Self-Assessment and Refining Your Idea
Authors should first identify the right genre through honest self-reflection. Choose a genre that aligns with your skills and passions; be genuinely enthusiastic about your topic. You can think about genre before, during, or even after writing your book. However, if you want to tailor your manuscript as effectively as possible to your target audience, the rule is simple: the earlier, the better.
Are you still developing your book idea? According to the Bookerfly Authors Congress, a strong book concept is built on five pillars: a unique twist, an emotional core, at least one character with an internal conflict, an interesting world or setting, and your personal “why.” Use storytelling techniques, for example, to make that emotional core tangible and engaging. Also keep publication density in mind: every year, 60,000–70,000 new traditionally published books are released, alongside a similar number of self-published titles. Your idea needs unique selling points to stand out from the crowd.
How can you get closer to choosing your genre? We have collected a few ideas for you: read books from different genres and note what you like and dislike. Reflect on yourself and your story to identify your genre. When and where does the story take place? Is there a romantic storyline? Is the story humorous? Is it based on real events? Which books, films, and characters inspire you?
For example, compile a list of 20 of your favorite titles and analyze which genres and tropes dominate. Once you have gathered a substantial selection, try the “traffic light method”: sort ideas into “green” (passion projects), “yellow” (ideas that need further development), and “red” (trend-driven concepts you are not truly passionate about). This helps you focus on projects that will motivate you in the long run.
It is also important to remain flexible in your genre choice. Stay open to changes during the writing process. A planned Romantasy novel may evolve into a pure romance if the fantasy elements do not feel right for you. You understand your personal strengths and the key pillars of your idea, it is worth looking outward: what genres exist, and what does the market currently look like?
Genre Research and Decision
Before publishing your book, you should clearly identify and define its genre in order to meet readers’ expectations. Become familiar with the characteristics of major genres such as novels, crime/thrillers, fantasy, romance, horror, biographies/ autobiographies, poetry, nonfiction, cookbooks, and children’s books. Research the available subgenres (e.g., Romantasy as a combination of romance and fantasy) and explore the main genres, subgenres, and hybrid forms that interest you. According to a BoD presentation, current trend topics include self-optimisation, Dark Romance, Romantasy, feminism, mental health, and queer literature. Ask yourself whether your book fills a unique niche and which subgenres exist within that niche market.
Market data from Jericho Writers also shows which genres perform particularly well in self-publishing: romance accounts for around 40% of Kindle self-publishing titles, mystery/thriller approximately 20%, fantasy around 50%,and science fiction as much as 56%. A Statista study cited in the BoD presentation shows that crime, thriller, and horror are among the most widely read genres. This information can further support your market analysis. Research which genres and subgenres are currently popular, for example through #BookTok, bestseller lists, and top-selling books in online stores. Monitor BookTok trends and bestseller charts to identify which genres and subgenres are currently in demand. However, one principle remains important: let trends inspire you without blindly chasing them.
For a solid market analysis, it can also be helpful to examine bookstores. Many booksellers see significant potential in self-published titles, particularly in regional fiction (77% approval), New Adult (46%), crime/thriller (26%), and fantasy (25%). Inform about current genre trends and subgenres without losing sight of your own strengths. In addition, identify comparable titles (comp titles or a comp pitch) to sharpen your positioning: “My book is like [Title A] meets [Title B].” This can be extremely helpful both when determining your genre and later when marketing your book.
We recommend that authors analyse successful books within their chosen genre, paying attention to plot structure, recurring themes, character archetypes, writing style, cover design, and reader reviews. Once you have an idea, use genre characteristics to determine where the story fits conceptually.
These insights form the foundation of your target audience analysis, because genre and readership are inseparably connected.
Target Audience and Expectation Management
Find out who your readers are before determining your genre. The best way to do this is by analyzing demographic and psychographic characteristics (age, gender, interests, and reading habits). Younger readers (under 30 years old), in particular, buy more books than older generations, and genres such as Romantasy and New Adult are currently booming. You can find an article and checklist on how to identify your target audience here. Find out which books your target audience reads and incorporate this information into your genre decision.
Readers expect genre-specific elements, but subgenres refine those expectations even further. By choosing a subgenre, you can target your audience more precisely. Understand the expectations associated with your chosen genre: writing style, tone, common tropes, and the typical dos and don’ts. Seek feedback from beta readers and professional editors who have experience in your genre. The service providers you work with should also have experience in the respective genre, as writing styles, reader expectations, and market conventions vary significantly. Pay attention to which subgenres are currently popular within your target audience (e.g., New Adult, coaching books, or vegan cookbooks) and use these insights without neglecting your own strengths and interests.
If you simply cannot decide on a genre or your book cannot be clearly assigned to one, this is known as a genre blend. When working with genre blends, the following rule applies: choose one primary genre and consider which readership is more flexible. Romance readers are generally more accepting of fantasy elements,whereas dedicated fantasy readers are often less tolerant of strong romantic storylines. The Self-Publishing Advice initiative recommends that authors of cross-genre books market them through comparisons with similar authors and communicate the content honestly in order to avoid disappointing readers.
With this knowledge, you can strategically align your marketing efforts.
Marketing and Promotion
Once you have chosen a genre, translate that decision into your title, subtitle, cover design, and book description —they should clearly reflect the genre and overall mood of your book. The right genre determines the visual style and tone of your marketing campaign. Optimize your metadata accordingly. Careful keyword research will help you identify long-tail keywords that can make your book more visible in search results. To do this, use auto-suggest resultsfor titles, subtitles, and keywords, and take popular tropes and trending topics such as Romantasy or Mental Health into account. Then align your distribution and pricing strategy with your target audience. Make sure your genre is reflected in your book marketing; suitable hashtags and influencers depend directly on it.
Plan your publication holistically: pre-launch marketing (cover reveal, pre-orders), launch activities (advertising, blogger collaborations, review copies), and post-launch measures (newsletters, social media series, and ads). Also keep the bookseller’s perspective in mind: self-published titles are requested weekly, and 61% of bookstores stock them. Social media and personal recommendations are key sources of information for booksellers when making purchasing decisions. The chosen subgenre determines where the book is categorized in both physical and online bookstores—pay attention to this so that your target audience can find your book.

Conclusion and Outlook
One principle remains true: authenticity beats trend-chasing. Follow the genres and tropes that genuinely excite you instead of focusing solely on market trends. The “traffic light method” can help youeliminate ideas that are likely to lead to burnout. Genres are a tool, not a straitjacket.
You can break conventions, but you should be aware of the expectations this creates for readers. Focus on sustainability rather than chasing bestseller hype: think long-term and build your author brand. Readers are more likely to buy from authors they perceive as real people and whose voice they recognize. Trends can provide inspiration and help you understand the market, but your own strengths and interests should remain at the center of your work. Your genre choice may evolve during the creative process—what matters most is that authenticity and long-term growth remain your guiding principles.

Frequently asked questions
Finding the right genre begins with an honest self-assessment: evaluate your strengths and interests, analyze which genres dominate your favorite books, and explore current market trends. It is recommended to think about which genre your content fits into before you start writing, but you should remain flexible and adjust the genre if necessary as your project develops. What matters most is choosing the correct classification, as a book’s placement in bookstores and online shops depends on it. A clear genre assignment makes it easier for readers to find your book and helps prevent false expectations.
A genre describes the broad category of a book (e.g., novel, crime/thriller, fantasy, or romance), while a subgenre is a more specific classification that gives readers a clearer idea of what to expect. Subgenres such as Romantasy (a blend of romance and fantasy) or coaching -books within the nonfiction category help target a more specific audience and manage reader expectations more effectively. For this reason, you should choose not only the right genre but also a suitable subgenre to maximize your book’s chances of success.
The people you want to reach with your book have a significant influence on your genre choice. Find out which books are popular among your target audience and use that information to guide your decision. Readers under the age of 30 purchase a particularly high number of books, and genres such as Romantasy and New Adult are currently experiencing strong growth. By conducting a thorough target audience analysis, you can make more informed decisions about your book’s style, tone, and common tropes, helping you meet reader expectations and avoid disappointing your audience.
Trends and bestseller rankings are constantly changing. BoD recommends monitoring your target audience’s current preferences through social media channels such as #BookTok, bestseller lists, and top-seller rankings on onlinebookstores. For example, Statista -data shows that crime, thriller, and horror are among the most widely read genres. At the same time, you should avoid blindly chasing trends. Stay true to your own style and use trends primarily as a source of inspiration rather than as the sole basis for your writing decisions.
Keywords are essential terms that reflect the core aspects of your book—its topic, genre, and target audience. Ingram recommends choosing specific, meaningful keyword phrases and incorporating them into your title, subtitle, book description, and other metadata. Long-tailkeywords such as “historical romance novel” face less competition and help you reach readers who are actively searching for exactly that type of book. Regularly monitor which keywords perform well, adjust them to reflect current trends, and use them consistently in hashtags as well as in your Amazon KDP settings.
