“Write to market” is one of the most misunderstood phrases in self-publishing. Some authors use it as an excuse to write the same book over and over with the names swapped. Others reject it completely because they think it means giving up their creative soul.
Neither is right, and both will cost you.
What it actually means
Writing to market means understanding what a specific group of readers wants, and then delivering it.
Every subgenre comes with an unspoken promise:
- Romance: a central love story and a guaranteed happy ending.
- Dark romance: high stakes, morally grey characters, intense power dynamics.
- Romantic comedy: banter, chaos and a warm, funny ride to the ending.
- Cozy anything: comfort, community, nothing too brutal on the page.
Break the promise and readers feel cheated, however beautiful your prose is. Keep it and they’ll follow you from book to book.
The restaurant principle
Think of your subgenre like a restaurant. Readers walk into an Italian restaurant expecting pasta. You can make the best, most surprising pasta they’ve ever had. Serve sushi and they’ll leave angry, even if it’s great sushi.
- The genre is the restaurant.
- The reader promise is the menu.
- Your voice is the kitchen.
Deliver the meal they came for. Put your creativity into how you cook it.
Where your creativity goes
Writing to market still leaves you tons of room:
- Your voice: how your characters talk, think and joke
- Your twists: a fresh angle on a familiar trope
- Your world: the setting, the side characters, the details only you would think of
- Your emotion: what you make readers feel along the way
How to research your market, step by step
1. Find your list. On Amazon, go to Best Sellers, then Kindle Store, then Kindle eBooks, then Romance, and keep clicking down until the list matches the kind of book you want to write. Bookmark it.
2. Study the top 20. Not to copy, but to learn the promise. For each book, notice:
- the cover: colors, fonts, people or objects
- the title: which words and trope signals keep showing up
- the blurb: the tone, and which tropes it names outright
- the length: the page count in the product details
- the series: is it part of one, and which book is selling best?
3. Pick your comps. Choose three bestsellers that are the closest match to the book you want to write. These are your comparable titles, and you’ll use them for everything from your voice to your cover.
4. Mine the reviews. Five-star reviews tell you what readers loved. One- and two-star reviews from clear fans of the genre tell you exactly where a book broke the promise. If ten reviews complain the hero went soft halfway through, that’s a rule you don’t break.
5. Spot the tropes that keep showing up. Those are what readers search for. Pick the ones you actually love reading, because enthusiasm shows on the page.
6. Ask AI to help you see the patterns. Paste the blurbs of the top 10 into a chat and ask: “What tropes, hooks and promises keep showing up? What tone do they share? What might readers want that’s missing?” You still make the call, but it saves an hour.
Run the three-question test
Before you commit to a subgenre, ask:
- Is there an active, hungry audience for this exact subgenre?
- Are readers buying books in it regularly, and a lot of them?
- Do I care enough about it to write several books in it?
Don’t skip the third one. Readers can tell when an author is faking interest to chase a quick buck.
Trends vs. markets
A market is a subgenre with a lasting readership, like dark romance or romantasy. A trend is a smaller wave inside it, like a sudden spike in hockey heroes or a particular aesthetic.
Chasing every viral trend burns you out and splits your brand. Being aware of trends, and working the ones that fit your subgenre into your next book, is just smart.
