How to Find Low Competition Keywords for Amazon KDP
Finding low competition keywords is the single most effective strategy for getting your Amazon KDP books discovered by hungry readers. While most authors fight over saturated, high-volume keywords like "romance" or "self-help," smart publishers target specific phrases that fewer books compete for—yet still attract motivated buyers. This comprehensive KDP keyword research guide walks you through a proven step-by-step framework for uncovering hidden keyword gems that can propel your book to page one of Amazon search results. Whether you publish fiction, non-fiction, or low content books, mastering low competition keyword research is the fastest path to consistent sales and long-term visibility on Amazon KDP.
1Why Low Competition Keywords Are the Key to KDP Success
Most new authors make the mistake of targeting broad, ultra-competitive keywords. A keyword like "cookbook" has millions of competing results and is virtually impossible to rank for as an indie author. But a phrase like "air fryer cookbook for beginners with pictures" has far fewer competing books, attracts readers who know exactly what they want, and converts at a much higher rate. Low competition keywords are phrases where the top-ranking books have fewer reviews, weaker covers, or less optimized metadata—meaning you can realistically outrank them with a well-optimized listing. The math is simple: ranking on page one for a keyword with 2,000 monthly searches and low competition will generate far more sales than ranking on page five for a keyword with 50,000 searches and brutal competition. KDP keyword research is not about finding the biggest keywords—it is about finding the right keywords where you can actually win.
2Step 1: Brainstorm Seed Keywords from Your Book Content
Every successful KDP keyword research process starts with seed keywords—the foundational terms that describe your book. Open a spreadsheet and list every word and phrase that relates to your book. For fiction, include your genre, subgenre, tropes, setting, character types, mood, and comparable titles. For non-fiction, list your topic, subtopics, target audience, problems solved, and methods taught. For example, if you wrote a productivity book for remote workers, your seed keywords might include: productivity, time management, remote work, work from home, focus, deep work, digital minimalism, home office, and freelancer organization. Aim for 30 to 50 seed keywords before moving to the next step. Do not filter or judge at this stage—quantity leads to quality. These seeds will be expanded and validated through research in the following steps.
3Step 2: Expand Your List with Amazon Autocomplete
Amazon autocomplete is the most powerful free KDP keyword research tool available. Go to Amazon.com, click into the search bar, and type one of your seed keywords. Amazon will instantly suggest popular search phrases based on real customer searches. These suggestions represent actual reader demand. To extract maximum value, use the alphabet soup method: type your seed keyword followed by each letter of the alphabet. For example, type "productivity book a" and note suggestions like "productivity book for adults" or "productivity book adhd." Then try "productivity book b" for results like "productivity book for busy moms" or "productivity book beginners." Continue through the entire alphabet. Each suggestion is a real search term that readers use. Copy every relevant suggestion into your spreadsheet. This method typically generates 100 to 200 keyword ideas from just 5 to 10 seed keywords. These are goldmine phrases because they come directly from reader search behavior on the platform where you sell.
4Step 3: Analyze Competition for Each Keyword
Now comes the critical step that separates successful authors from those who waste their keyword slots. For each keyword on your expanded list, search it on Amazon and analyze the results. Look at the top 10 to 20 books that appear. Ask yourself these questions: How many reviews do the top books have? If the top results all have 500 plus reviews, competition is fierce. If several books in the top 10 have fewer than 50 reviews, you have a realistic chance of competing. How professional are the covers? Amateur covers in top positions signal an underserved keyword. How optimized are the titles and descriptions? Weak metadata in top results means opportunity. What is the Best Seller Rank of the top books? If the number one book for your keyword has a BSR above 100,000, demand may be too low. If it is under 50,000, there is healthy demand. The ideal low competition keyword has books ranking with fewer than 100 reviews, some amateur covers or weak descriptions, and at least a few books with BSR under 50,000 indicating real sales. Use our AI Book SEO Generator tool to speed up this analysis and get keyword suggestions tailored to your specific book.
5Step 4: Use Free and Paid Tools to Validate Search Volume
While Amazon autocomplete confirms that people search for a term, you also want to estimate how many people search for it. Several tools help with this. Publisher Rocket is the most popular paid tool among KDP authors, providing estimated Amazon search volume and competition scores for around 97 dollars one-time. For free alternatives, use Google Keyword Planner to gauge general interest in your topic. Sonar by Sellics is a free Amazon-specific keyword tool that shows related terms and relative search frequency. Book Bolt offers free research features for low content book keywords. Our own AI Book SEO Generator provides keyword suggestions with competition analysis built in—try it free to discover keywords optimized for your specific book and genre. When validating, look for keywords with moderate search volume (not too obscure, not too competitive) and clear commercial intent. A keyword like "best thriller books 2025" shows buying intent, while "what is a thriller" is informational and less likely to convert to sales.
6Step 5: Spy on Competitor Keywords
Your successful competitors have already done keyword research—learn from them. Identify 10 to 20 books similar to yours that rank well. Analyze their titles and subtitles for keyword patterns. What terms appear repeatedly across multiple successful books? Read their descriptions and note repeated phrases and benefit statements. Check which categories they are listed in—category names often reveal valuable keyword strategies. Look at their Also Bought sections for related keyword opportunities. For deeper analysis, use reverse ASIN lookup tools to see which keywords competitors rank for. Create a competitor keyword matrix showing which books use which keywords. This reveals both proven winners and gaps—keywords with demand that competitors are not targeting well. These gaps are your biggest opportunities for finding low competition keywords that still drive meaningful traffic and sales.
7Step 6: Prioritize Long-Tail Keywords for Quick Wins
Long-tail keywords—specific phrases of 3 to 6 words—are your secret weapon for ranking quickly on Amazon KDP. While "romance" has millions of competing books, "small town second chance romance with single dad" has far fewer competitors and attracts readers who know exactly what they want. Long-tail keywords convert 2 to 5 times better than generic terms because they match specific reader intent. Generate long-tail variations by combining elements from your seed keywords: genre plus trope plus setting, topic plus audience plus benefit, or problem plus solution plus method. For fiction examples: "enemies to lovers workplace romance," "cozy mystery with cats and recipes," or "epic fantasy with dragons and political intrigue." For non-fiction: "keto diet for busy moms over 40," "time management for entrepreneurs with ADHD," or "investing guide for beginners with little money." Prioritize 5 to 10 long-tail keywords that perfectly describe your book unique combination of elements. These specific phrases often have 10 to 50 times less competition than generic terms while attracting highly motivated buyers ready to purchase.
8Step 7: Place Your Keywords Strategically
Finding great keywords is only half the battle—where you place them determines their impact. Your title carries the most SEO weight, so include your single most important keyword naturally. Your subtitle provides space for 2 to 3 additional high-value keywords while clarifying your book value proposition. For example, a title like "Deep Focus" paired with a subtitle like "A Productivity Guide for Remote Workers Who Want to Get More Done in Less Time" naturally incorporates multiple keyword phrases. Your 7 backend keyword slots should complement your title and subtitle without repeating any words. Use all 50 characters per slot. Include synonyms, related terms, audience-specific phrases, and long-tail variations. Do not use commas—Amazon treats spaces as separators. Your book description should naturally incorporate your top 5 to 10 keywords, especially in the first paragraph. Focus on persuasive copy that happens to include strategic terms. Use our AI Book SEO Generator to automatically optimize keyword placement across your entire listing for maximum discoverability.
9Step 8: Monitor, Test, and Optimize Continuously
KDP keyword research is not a one-time task—it requires ongoing optimization. After publishing, track your book ranking for target keywords weekly. Use Amazon ads to test keyword performance: run campaigns targeting your chosen keywords and compare click-through rates and conversion rates. Keywords converting at 5 to 15 percent in ads are strong candidates for your metadata. Keywords generating impressions but no clicks indicate your cover or title is not compelling for that search. Keywords generating clicks but no sales suggest your description or pricing needs work. Update your backend keywords every 30 to 60 days based on performance data. Replace underperformers with new candidates from your research. Add seasonal keywords when relevant—"Christmas gift book" in November, "summer reading" in June. The most successful KDP authors treat keyword optimization as a core business activity, continuously refining their approach based on real performance data rather than guesswork. Schedule quarterly keyword reviews to stay ahead of competition and capture emerging search trends.
10Real Example: Finding Low Competition Keywords for a Cookbook
Let us walk through a real example to illustrate this framework in action. Imagine you have written an air fryer cookbook. Starting with seed keywords: air fryer, air fryer recipes, air fryer cookbook, healthy air fryer, quick meals. Using Amazon autocomplete with the alphabet method, you discover: air fryer cookbook for beginners, air fryer cookbook with pictures, air fryer cookbook for one, air fryer cookbook keto, air fryer cookbook for family, air fryer cookbook healthy, and dozens more. Analyzing competition, you find that "air fryer cookbook" has top results with 5,000 plus reviews—too competitive. But "air fryer cookbook for beginners with pictures" shows top results with only 30 to 150 reviews and several books with mediocre covers. This is a low competition keyword with clear demand. You also discover "air fryer cookbook for one person" has surprisingly few well-optimized competitors despite strong search interest. Your final keyword strategy targets these specific long-tail phrases in your title, subtitle, and backend keywords, giving you realistic ranking potential that broad terms never would.
11FAQ: KDP Keyword Research Common Questions
How many keywords can I use on Amazon KDP? Amazon provides 7 backend keyword fields with 50 characters each, plus your title and subtitle. Use every available character for maximum discoverability. Can I change my keywords after publishing? Yes, you can update backend keywords anytime at no cost through your KDP dashboard. Changes typically take effect within 24 to 72 hours. How do I know if a keyword has low competition? Search the keyword on Amazon and analyze the top 20 results. If multiple books in the top positions have fewer than 50 reviews, amateur covers, or weak descriptions, competition is low enough to target. What tools do I need for KDP keyword research? You can start with free tools like Amazon autocomplete and Google Keyword Planner. For more advanced research, Publisher Rocket and our AI Book SEO Generator provide competition scores and search volume estimates. How often should I update my keywords? Review and update your keywords quarterly at minimum. Update more frequently if you notice ranking changes or want to capture seasonal search trends. Should I use the same keywords for ebook and paperback? Your ebook and paperback share the same product page on Amazon, so backend keywords apply to both formats. However, you can optimize each format separately if they have different ASINs. What is the difference between high volume and low competition keywords? High volume keywords have many monthly searches but also many competing books. Low competition keywords may have fewer searches but far fewer competing books, making it easier to rank on page one and actually get discovered.
