Choosing the right niche is one of the most important steps in building a successful Amazon KDP business. Many beginners focus on creating books first, but experienced publishers know that niche research comes before publishing.
If you pick the wrong topic, your book may never get discovered. But if you choose a niche with strong buyer demand and low competition, your book can start getting organic sales without needing paid ads.
In this guide, you’ll learn two practical ways to find profitable Amazon KDP niches:
- A free beginner method using Amazon itself
- An advanced research method using Book Bolt’s keyword tools
Let’s start with why niche research matters so much.

Why Niche Research Matters in Amazon KDP
Amazon KDP is no longer a “hidden opportunity.” Over the past few years, thousands of creators have uploaded journals, planners, and puzzle books, which makes the marketplace highly competitive.
If you publish a book idea that many others have already created, your listing may end up buried deep in search results, where buyers rarely look.
That’s why niche research is essential.
The goal is to find niches where:
- People are actively searching for books
- Competition is still manageable
- You can rank and sell organically
This is the foundation of long-term success.
Why Word Search Books Are a Smart Niche Choice
Amazon KDP offers many categories, but one type of low-content book stands out: word search puzzle books.
Unlike blank journals (which are extremely easy to copy), puzzle books have a higher barrier to entry because the interior requires real puzzle creation.
That naturally reduces competition.
Many publishers use Book Bolt specifically because it supports puzzle creators along with keyword research and design tools.
Book Bolt describes itself as an all-in-one toolkit for niche research, keywords, and book creation.
So if you’re unsure where to begin, word search books are a strong starting category.
Method 1 (Beginner-Friendly): Find Niches Using Amazon Autocomplete
The first strategy is completely free, and you can do it right now.
Step 1: Open Amazon in Incognito Mode
Using a private window helps you see general search suggestions instead of results based on your personal browsing history.
Step 2: Use the Alphabet Soup Strategy
Go to the Amazon search bar and type:
word search books for a
Amazon will automatically suggest popular completions, such as:
- word search books for adults
- word search books for kids
- word search books for Christmas
These are not random suggestions — Amazon recommends them because people search for them frequently.
Then repeat the process with other letters:
- word search books for b
- word search books for c
- and so on
This method is excellent for brainstorming niche ideas quickly.
Limitation of the Free Method
Amazon autocomplete is great for ideas, but it does not tell you:
- How many people search each keyword
- How competitive the niche really is
That’s where advanced tools come in.
Method 2 (Advanced): Find Profitable Niches Using Book Bolt
If you want accurate niche data, Book Bolt is one of the most widely used keyword research tools in the KDP space.
Book Bolt provides keyword research features designed specifically for Amazon publishers and low-content books.
Step 1: Use the Book Bolt Keyword Search Tool
Once inside Book Bolt, go to:
Keywords → Search
Book Bolt confirms that the Keywords tool includes two main sections:
- Search
- Favorites
This workflow is explained directly in their keyword tool guide.
Now type a seed keyword such as:
word search
Book Bolt will generate hundreds of related Amazon keyword searches, along with search volume insights.
Book Bolt highlights that its keyword module helps uncover profitable niches and keyword ideas quickly.
Step 2: Save Keywords Into Favorites
As you scroll through results, you can save niche ideas by clicking the heart icon.
For example, you may find keywords like:
- adventure word search
- anxiety word search
- camping word search
- astronomy word search
These become your niche candidates.
Step 3: Analyze Competition Inside Favorites
After saving ideas, go to:
Keywords → Favorites
This is where Book Bolt becomes powerful because you can click “Details” and view deeper metrics.
Book Bolt explains that its keyword tool provides useful insights like:
- Estimated monthly sales volume
- Search demand
- Competition evaluation
Example: How Keyword Competition Helps You Choose Niches
Here is what a niche evaluation might look like:
| Niche Keyword Idea | Demand Level | Competition Opportunity |
|---|---|---|
| Adventure word search | Strong searches | Low competition potential |
| Anxiety word search | Consistent interest | Great niche gap |
| Camping word search | Evergreen topic | Easy to target |
| Army word search | Clear audience | Buyers actively search |
The goal is always the same:
high demand + low competition = profitable niche
Best Keyword Variations to Research
To expand your niche list further, Book Bolt recommends searching multiple seed variations, such as:
- word search
- word search book
- word find
- word puzzle
This gives you hundreds of additional keyword directions for book creation.
Book Bolt also provides related tools like Book Scout and competitor analysis features for deeper research.
Final Advice
Many Amazon KDP beginners spend days creating books, only to realize later that the niche is overcrowded.
Instead, reverse the process:
- Start with niche research
- Validate demand
- Check competition
- Then create the book
That way, every book you publish is backed by real market data.
