How to Find Low-Competition KDP Niches (The BSR + Autocomplete Method)
Most publishers compete in niches they can't win. Here's the 5-step system for finding low-competition KDP niches using Amazon's own data — autocomplete, BSR, and the 50-review rule.
Most new KDP publishers make the same mistake: they pick a niche based on what they want to write about, then wonder why nobody buys it. The publishers making real money do it backwards — they find where demand exists and competition is weak, then create the book.
Here's the system that works, using data Amazon gives you for free.
The Core Idea: Pick Fights You Can Win
A book about "fitness" competes against millions of titles. A book about "desk exercises for remote workers" competes against maybe 200.
Both serve real audiences. But one is a war you can't win, and the other is a niche where a decent book with 30 reviews can rank #1.
The goal isn't to find the biggest market. It's to find the market where you can realistically reach the top of the results page.
Would you rather rank #50,000 in a huge niche (zero sales) or rank #5 in a small niche ($500+/month)? The math is obvious — but most publishers never do the research to find those small niches.
Step 1: Use Amazon Autocomplete for Free Market Research
Amazon's search bar is the single best free research tool available. When you type a phrase, Amazon shows you what real buyers are searching for, ranked by popularity.
How to do it:
- Go to Amazon.com → Books
- Start typing a broad topic and watch the autocomplete suggestions
- Write down every suggestion that could be a niche
Example: Type "how to train" and you get:
- How to train your voice
- How to train your memory
- How to train a puppy
- How to train for hiking
Each one is a potential niche with built-in demand.
Go deeper with the alphabet method:
- "coloring book for a" → adults, animals, anxious kids...
- "coloring book for b" → boys, beginners, birthdays...
- "activity book for c" → christmas, car rides, classrooms...
This reveals long-tail niches you'd never think of on your own.
BookCreatorStudio's keyword miner automates this entire process. It scrapes Amazon autocomplete across 4 marketplaces (US, UK, DE, CA), scores each keyword by opportunity, and exports to CSV. What takes 30 minutes manually takes 30 seconds with the tool — and it works for KDP, Etsy, and Pinterest keywords.
Step 2: Find the BSR Sweet Spot
BSR (Best Seller Rank) is Amazon's sales ranking for every book. Lower number = more sales. The #1 bestselling book has BSR 1. A book that hasn't sold in weeks might have BSR 2,000,000.
The sweet spot for low-competition niches:
| BSR Range | What It Means | Strategy |
|---|---|---|
| Under 10K | Massive sales, huge competition | Avoid as a new publisher |
| 10K–100K | Strong sales, heavy competition | Hard to break in without a big budget |
| 100K–500K | Moderate sales, manageable competition | Your target zone |
| 500K–1M | Low sales, very little competition | Demand may be too weak |
| Over 1M | Almost no sales | Skip entirely |
The key insight: Don't look at the #1 book's BSR. Look at the #5 or #10 book's BSR. If the 5th-ranked book in a niche has a BSR of 200K+, that niche has room for you.
Where to find BSR: scroll down any Amazon book product page to "Product Details" — the BSR is listed there, along with the categories it ranks in.
Step 3: Competition Analysis (3 Minutes Per Niche)
Search your niche phrase on Amazon and check the top 10 results for these four things:
Review Count
- Under 50 reviews on the #1 book = very beatable
- 50–100 reviews = beatable with effort
- 100+ reviews = hard to outrank quickly
- 500+ reviews = dominated — move on
Cover Quality
- Amateur-looking covers (generic clip art, bad fonts, poor composition) = opportunity
- If you can make a noticeably better cover, you have an advantage
- For coloring books: check if the interior art is actually good or just AI-generated filler
Description Length and Quality
- Short, lazy descriptions = competitors who aren't trying hard
- Well-optimized descriptions with bullet points, keywords, and clear benefits = serious competitors
- Most low-competition niches have at least a few competitors with weak descriptions
Publication Date
- Books published in 2020–2023 that haven't been updated = stale content you can replace
- Recently published books with few reviews = other people are already finding this niche
- A mix of old and new books = healthy niche with ongoing demand
If the top 10 results show: most books under 100 reviews, amateur covers, short descriptions, and some haven't been updated in 2+ years — you've found a low-competition niche. Time to validate demand.
Step 4: Validate Demand with Social Proof
Before you invest time creating a book, confirm that real people care about this topic.
Quick validation checks:
- Facebook groups: Search for your niche. 3+ active groups with engaged members = people care about this topic. A group with 10K+ members and daily posts is strong validation.
- Reddit: Is there a subreddit for this topic? Are people asking questions that a book could answer?
- Google Trends: Is interest stable, growing, or seasonal? A flat or growing trend is good. A spike-and-crash pattern means seasonal demand.
- Pinterest: Are there pins and boards about this topic? Pinterest is a visual search engine — high pin counts = people are actively looking for this content.
If nobody is discussing your topic anywhere online, there probably isn't enough demand to support book sales.
Step 5: The 50-Review Rule
Here's the simplest competitive benchmark in KDP:
If the #1 book in your niche has under 50 reviews, you can probably outrank it with a quality book and basic marketing (reviews + ads).
50 reviews is the threshold where a book becomes "established" in Amazon's algorithm. Below that, the top position is fragile — a better book with a better cover and a focused review campaign can overtake it within a few months.
Above 50 reviews, the incumbent has momentum. Not impossible to beat, but it takes significantly more time and money.
Niches That Tend to Be Low-Competition
These aren't specific recommendations — they're categories where the dynamics tend to favor new publishers. Always do your own research using the steps above.
Local/Regional:
- Weekend trips from [your city]
- Street food guide [your state/region]
- Gardening for [your climate zone]
Hobby sub-niches:
- Balcony gardening for apartments
- Sketching for absolute beginners
- Meditation for insomniacs
- Indoor herb gardening for small spaces
Age-specific:
- Exercise after 50
- Retirement planning for freelancers
- Puzzles for seniors large print
Problem-specific:
- Desk exercises for remote workers
- Meal prep for one person
- Sleep hygiene for shift workers
A niche like "Christmas crafts for kids" will spike in November and die in January. If you publish seasonal content, plan for the dip — either have multiple seasonal books across the year, or focus on evergreen niches that sell consistently month after month.
Don't Forget International Markets
Most publishers only research Amazon.com (US). The same book might face completely different competition on:
- Amazon.co.uk (UK)
- Amazon.de (Germany)
- Amazon.ca (Canada)
- Amazon.co.jp (Japan)
- Amazon.com.au (Australia)
A niche that's saturated in the US might be wide open in the UK or Germany. If you can translate or adapt your content, international markets are an underused growth lever.

Brainstorm with autocomplete
Go to Amazon Books, type broad phrases, and write down every autocomplete suggestion that could be a niche. Use the alphabet method to find long-tail variations.
- 2
Check BSR of top results
Search each niche and look at the BSR of the #5-#10 book. If it's between 100K-500K, the niche has demand without being dominated.

Analyze competition
Check review counts (under 100 = good), cover quality (amateur = opportunity), and description quality (short = lazy competitors).
