Choose the niche on demand signals, not on taste
A catalog operator is not picking a passion project. You are looking for a reader who is actively trying to solve something and already buying books about it. That reader leaves evidence: they ask the same question repeatedly, and the existing answers are thin.
- Look for a specific job, not a topic — 'stop my sourdough from going flat' beats 'baking'.
- Check that books in that niche have recent reviews. Recent reviews mean recent buyers.
- Read the 3-star reviews of the top sellers. They name the gap your book fills.
- If the top of the category is dominated by strong brands with hundreds of reviews, go one level narrower.
The mistake: Choosing a niche because the keyword volume is high. High volume with strong incumbents is the hardest possible place to start.
