Amazon Keyword Research: A Complete Beginner's Guide for FBA Sellers

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.

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:

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.
