Amazon Keyword Research: A Complete Beginner's Guide for FBA Sellers
May 8, 2026 · 8 min read · TagReveal Editorial
If you are selling on Amazon, keywords are everything. The right keywords determine whether your product appears on page one or page ten of Amazon search results. In this complete guide, we will walk you through Amazon keyword research from start to finish — without spending money on expensive tools.
Why Amazon Keyword Research Matters
Amazon is primarily a search engine for products. When a customer types "wireless earbuds for running" into Amazon's search bar, Amazon's A9 algorithm scans millions of listings to decide which products to show first. If your listing does not contain that exact phrase — or close variations of it — your product will be invisible.
Studies consistently show that products on page one of Amazon search results get over 70% of all clicks. Page two gets almost nothing. This is why Amazon keyword research is not optional — it is the foundation of everything else you do as an Amazon seller.
Understanding Amazon's Keyword System
Amazon uses keywords in two main places:
- Frontend keywords: Words that appear in your product title, bullet points, and description. Customers can see these.
- Backend search terms: Hidden keywords you enter in your Seller Central account under "Keywords". Customers cannot see these but Amazon indexes them.
You should be optimising both. Most beginners only think about their title, but the backend search terms field gives you up to 250 bytes of additional keyword space that is completely invisible to competitors.
💡 Pro tip: Amazon's backend search terms field does not need punctuation or repeated words. Just write keywords separated by spaces. Amazon is smart enough to understand them.
Step 1 — Start With Competitor Research
The fastest way to find great keywords is to look at what your best competitors are already ranking for. Find the top 3-5 products in your category — the ones with hundreds of reviews and "bestseller" or "Amazon's Choice" badges. These products have been tested and optimised over time.
Look carefully at their:
- Product titles — what exact phrases do they use?
- Bullet points — what features do they emphasise?
- Product descriptions — what problem are they solving?
Write down every keyword and phrase you see. This gives you a proven keyword list based on what is already working in the market.
Step 2 — Use Free Keyword Research Tools
Once you have a seed list from competitor research, use free tools to expand it. TagReveal is a free keyword extractor that lets you paste any Amazon product URL and instantly see the keyword opportunities hidden in that listing's URL structure.
Other free methods include:
- Amazon auto-suggest: Type your main keyword into Amazon's search bar and look at the dropdown suggestions. These are real searches customers make.
- Google Keyword Planner: Free with a Google account. Shows search volumes for keyword ideas.
- Answer the Public: Shows questions people ask around your topic — great for long-tail keywords.
Step 3 — Identify Long-Tail Keywords
New sellers make the mistake of only targeting broad keywords like "wireless earbuds" which have millions of competing listings. Instead, target long-tail keywords — phrases of 3-6 words that are more specific.
For example, instead of "wireless earbuds", target:
- "wireless earbuds for small ears women"
- "wireless earbuds with longest battery life"
- "wireless earbuds waterproof for swimming"
These longer phrases have less competition, higher buyer intent (people know exactly what they want), and are much easier to rank for as a new seller.
Step 4 — Optimise Your Title First
Your product title is the most important place for keywords. Amazon gives it the most weight in their algorithm. A well-optimised title format for most categories is:
Brand Name + Main Keyword + Key Features + Size/Quantity + Colour
Example: "SoundPro Wireless Earbuds for Running — Waterproof Bluetooth Earphones with 40hr Battery — Small Ear Tips Included — White"
Keep your title under 200 characters. Use your most important keywords near the beginning since Amazon truncates titles in search results.
Step 5 — Fill Your Backend Search Terms
In Amazon Seller Central, go to your listing and find the "Keywords" section. Use all 250 bytes available. Tips for backend keywords:
- Include common misspellings of your product name
- Include Spanish or other language keywords if relevant to your market
- Include competitor brand names (Amazon allows this)
- Do not repeat words already in your title
- Do not use commas — just spaces
Tracking and Improving Your Keywords
Keyword research is not a one-time task. After launching, monitor your search term report in Seller Central to see which keywords are actually driving sales. Double down on what works and remove what does not. Revisit your keyword research every 3-6 months as search trends change.

Understanding Search Volume and Competition
Not all keywords are equal. A keyword like "laptop" has enormous search volume — millions of searches per month — but also millions of competing listings. A keyword like "lightweight laptop for college students under 500 dollars" has far lower volume but dramatically less competition. The sweet spot for most sellers is keywords with moderate search volume and low competition.
According to data from multiple Amazon seller communities, new listings that target long-tail keywords with fewer than 5,000 competing results rank significantly faster than those chasing high-volume broad terms. This is why experienced sellers often recommend starting with 3-5 highly specific keywords rather than 20 generic ones.
Search volume vs competition formula: A keyword scoring well is one where the top results have fewer than 200 reviews and the keyword gets at least 500 monthly searches. This sweet spot represents an achievable ranking target for new or growing listings.
Amazon Keyword Research Using Free Tools
You do not need to spend money to do effective Amazon keyword research. Several free methods consistently surface high-value keywords that paid tools also find. The key is combining multiple methods to build a comprehensive keyword list.
Method 1 — Amazon's Search Bar: This is the most underused free tool available. Type your main product keyword and watch the autocomplete suggestions appear. Each suggestion is a real search term Amazon customers use. Type your keyword followed by each letter of the alphabet to uncover hundreds of variations. For example, "wireless earbuds a..." reveals "wireless earbuds apple compatible", "wireless earbuds around ear", "wireless earbuds adjustable".
Method 2 — Amazon's "Customers Also Searched For": Scroll to the bottom of any Amazon search results page and look for the "Related searches" section. These are phrases Amazon itself suggests based on buyer behaviour — invaluable data that reflects actual purchase patterns.
Method 3 — Competitor Review Mining: Read the 4 and 5-star reviews of your top competitors. Buyers naturally describe their purchase in search-like language. Phrases like "perfect for small apartments", "exactly what I needed for camping", or "much better than the other brands" contain keyword gold.
Method 4 — TagReveal URL Analysis: Paste any top competitor's Amazon URL into TagReveal to instantly extract the keyword strategy embedded in their listing. TagReveal detects the product category and generates buyer-intent keywords organised by placement — title keywords, bullet point keywords, and backend search term suggestions.
Building Your Keyword List — A Systematic Approach
Random keyword selection is one of the most expensive mistakes Amazon sellers make. A systematic approach ensures you capture the full keyword opportunity for your product:
- Seed keywords first: Start with 3-5 obvious keywords that describe your product. These are your foundation.
- Expand each seed: Use Amazon autocomplete, TagReveal, and Google to find 10-20 variations of each seed keyword.
- Categorise by intent: Separate keywords into browsing intent (general) and buying intent (specific). "Bluetooth speaker" is browsing. "Waterproof bluetooth speaker for shower under 30 dollars" is buying.
- Prioritise by placement: Your 2-3 most important buying-intent keywords go in your title. Supporting keywords go in bullets. Everything else goes in backend search terms.
- Track and iterate: After 4-6 weeks, check your Search Term Report in Seller Central to see which keywords are generating clicks and conversions. Remove underperformers and test new candidates.
Amazon Keyword Mistakes That Cost Sellers Money
Understanding what not to do is as important as knowing best practice. These are the most common Amazon keyword research mistakes that experienced sellers observe repeatedly:
- Keyword stuffing the title: Cramming too many keywords into your title makes it unreadable and actually hurts conversion rates. A clear, readable title with 1-2 strong keywords consistently outperforms a keyword-stuffed one.
- Ignoring seasonal keywords: Many products have significant seasonal keyword variations. "Christmas gift for dad" and "Father's Day gift" can both describe the same product at different times of year. Plan your keyword rotation around the calendar.
- Not using all backend search term space: Amazon gives you 249 bytes of invisible keyword space. Many sellers use less than half of it. Fill every byte with relevant search terms that do not appear in your title or bullets.
- Copying competitors exactly: Your competitors may be making the same keyword mistakes you are trying to avoid. Analyse their listings critically, not as definitive examples to copy exactly.
- Setting and forgetting: Amazon's search landscape changes constantly. New competitors enter. Seasonal trends shift. Buyer language evolves. Keywords that worked 12 months ago may be suboptimal today.
Advanced Amazon Keyword Strategy — PPC Data
If you run Amazon PPC (Pay Per Click) advertising, your campaign data is one of the most valuable keyword research sources available. Search Term Reports from your campaigns show you exactly which keywords caused buyers to click on your ad and — more importantly — which ones resulted in actual sales.
The standard advice is to harvest high-converting search terms from your automatic campaigns and add them as exact match keywords in manual campaigns. But equally important is adding poor performers as negative keywords to stop wasting budget on searches that click but never convert.
Even a small PPC budget of $5-10 per day run for 2-3 weeks generates enough data to identify your 10-20 highest-converting keywords. This data is more valuable than any keyword tool because it reflects real buyer behaviour on your specific product at your specific price point.
