The Category-First Framework
Most authors start with a topic and then try to find an audience. The most successful authors we work with do the opposite — they start with a verified audience gap and then engineer a book to fill it.
This isn't about compromising your message. It's about making sure your message reaches the readers who are actively searching for it.
Step 1: Go to Amazon and Search, Don't Browse
Open Amazon Books. Type in the broad topic you want to write about. Don't go to bestseller lists yet. Use the search bar as your audience research tool.
What are people typing when they're looking for books like yours? Those are your real keywords — not the categories Amazon assigns later, but the language your reader uses at the moment of desire.
Step 2: Check Monthly Search Volume
Amazon doesn't share search data publicly, but Publisher Rocket (a tool we use internally) does. Look for keywords with 1,000–10,000 monthly searches. Too low means no audience. Too high means established competition with massive marketing budgets.
The sweet spot is a keyword with strong search volume and weak competition — books in the category that have fewer than 100 reviews, poor cover design, or dated content.
Step 3: Validate with Category Rankings
Find the top 20 books in your target category. Look at their Amazon Best Seller Rank (ABSR). An ABSR under 100,000 means the book is selling at least 1–2 copies per day. If the top 5 books in a category all have ABSRs under 50,000, that category has commercial demand.
Step 4: The "Unique Angle" Test
Before committing to a topic, write one sentence: *This book is for [specific person] who wants [specific outcome] but struggles with [specific obstacle].*
If you can't write that sentence clearly, the topic isn't focused enough.
The Most Common Mistakes
**Choosing a topic you love instead of a topic readers need.** Passion is necessary but insufficient. The question isn't whether *you* care — it's whether *they* care enough to open their wallets.
**Targeting too broad a category.** "Leadership" is not a category. "Leadership for first-time managers in tech companies" is a category.
**Ignoring the cover test.** Before finalizing your topic, look at the covers of the top 10 books in your target category. If you can't imagine a cover that stands out from those, reconsider the positioning.
Our Recommendation
At BPL, every author engagement starts with a Category Intelligence report — 15 pages of Amazon keyword data, ABSR analysis, competitor mapping, and positioning recommendations. It's the single most valuable document we produce for authors, and it's completed before a single chapter is outlined.
If you're serious about publishing, do this research first. It changes everything downstream.
