How to Find Keywords on Amazon: Step-by-Step Guide

Every product that ranks on page one of Amazon started with keyword research. Understanding how to find keywords on Amazon is the single most important skill a seller can develop — it determines whether shoppers ever see your product in the first place. Without the right keywords in your listing, your product is invisible to the 310+ million active Amazon customers searching for exactly what you sell.

This guide walks you through every method for finding high-performing Amazon keywords, from free manual techniques to advanced tool-based workflows. If you want to understand the broader Amazon SEO framework that these keywords fit into, start with our Amazon SEO keyword research guide for the foundational concepts.

For sellers who already have a product live and want to improve their rankings, our guide on how to optimize your Amazon listing shows exactly where to place the keywords you discover through the methods below.

Understanding How Amazon Search Works

Before diving into specific methods for how to find keywords on Amazon, you need to understand what the search algorithm actually looks for. Unlike Google, which indexes billions of web pages, Amazon’s search engine (historically called A9, now augmented by the AI-powered Rufus system) indexes product listings — and its sole goal is to show shoppers the products they are most likely to buy.

According to Amazon Seller Central, the algorithm weighs three primary factors when ranking products for any given search query.

Relevance: Does the listing contain the keywords the shopper typed? This is the factor you control most directly through keyword research. If a shopper searches “organic green tea bags” and your listing only contains “green tea,” you may not appear for the more specific — and often higher-converting — query.

Performance: Does the product have strong sales velocity, a healthy conversion rate, and competitive pricing? Performance metrics tell Amazon that shoppers who find your product actually want to buy it.

Customer satisfaction: Does the product deliver on its promise? Low return rates, positive reviews, and strong seller feedback signal that the product is worth recommending to future shoppers.

Keywords directly influence factor number one. This is why comprehensive keyword research matters — it ensures your listing covers every relevant search term shoppers use, not just the obvious ones you can guess on your own.

Method 1: Amazon Autocomplete (Free)

The simplest way to start finding keywords is typing your main term into Amazon’s search bar and observing the autocomplete suggestions. These suggestions are pulled directly from real shopper searches, making them highly relevant and validated by actual buyer behavior.

How to use Amazon autocomplete effectively

Go to Amazon.com or your target marketplace. Type your primary keyword slowly — for example, “yoga mat” — and note every autocomplete suggestion that appears. Then add a letter after your keyword: “yoga mat a,” “yoga mat b,” “yoga mat c,” and so on. Each letter surfaces additional suggestions that you would never discover otherwise. Repeat this process with synonyms and related terms to build a comprehensive initial list.

Limitations of autocomplete

Amazon autocomplete shows you real search terms, but it provides no data on search volume, competition level, or historical trends. You can see what people search for, but not how many people search for it or how hard it would be to rank for it. Treat autocomplete as a brainstorming starting point — not a complete research strategy. Pair it with at least one data-driven method from this guide to get the full picture.

Method 2: Competitor Listing Analysis

Your competitors have already done keyword research — often spending thousands of dollars on tools and consulting. You can learn from their work for free by analyzing their listings systematically.

Step-by-step competitor analysis

Search your main keyword on Amazon and open the top 5–10 best-selling products in your niche. Read each listing carefully — the title, every bullet point, the full description, and the A+ Content modules. Note every relevant keyword and phrase they use, paying special attention to terms that appear across multiple competitor listings.

The product title deserves the most attention. This is where sellers place their highest-priority keywords because the title carries the most ranking weight. If three out of five competitors use “BPA-free” in their title, that is a strong signal that “BPA-free” is a high-volume search modifier in your niche. Similarly, if every competitor includes “non-slip” but you do not, you are likely missing traffic from shoppers who specifically want that feature.

For a deeper layer of competitor intelligence, check their backend search terms using a reverse ASIN tool (covered in Method 4). Backend keywords are invisible to shoppers but visible to the algorithm, and competitors often hide their most strategic long-tail terms there.

Method 3: Amazon Brand Analytics (Free for Brand-Registered Sellers)

If you are enrolled in Amazon’s Brand Registry program, you have access to Brand Analytics — the only source of first-party Amazon search data available to sellers. This is the most authoritative way to learn how to find keywords on Amazon because the data comes directly from Amazon’s own systems rather than third-party estimates.

Key reports and how to use them

Practical workflow for Brand Analytics

Log into Seller Central, navigate to Brand Analytics, then Search Query Performance. Filter by your ASIN to see which keywords currently drive traffic to your product. Export the data and sort by impressions and click share. Identify keywords where you have impressions but low click-through rate — these are optimization opportunities where a better title or main image could capture more traffic. Then find keywords where competitors get clicks but you do not — these are gap keywords to add to your listing immediately.

Method 4: Reverse ASIN Lookup (Tool-Based)

Reverse ASIN lookup is the most powerful method for how to find keywords on Amazon. It works by entering a competitor’s ASIN into a tool that reveals every keyword that product currently ranks for — both organically and through paid ads.

How to run a reverse ASIN lookup

Find 5–7 top competitors in your niche and copy their ASINs from the product URL or listing page. Enter them into a reverse ASIN tool — Helium 10 Cerebro, Jungle Scout Keyword Scout, or a similar platform. Filter results by minimum search volume of 500 per month, organic rank within the top 50, and a relevance score above 50% where available.

The multi-ASIN comparison technique

Instead of analyzing one competitor at a time, enter all 5–7 ASINs simultaneously. This reveals keywords that the majority of top sellers rank for, which are almost certainly the most important terms in your niche. Keywords where all seven competitors rank organically in the top 20 are must-have terms for your listing — missing even one of them means losing traffic to every competitor who includes it.

For sellers already running PPC campaigns, reverse ASIN data is invaluable for building Amazon PPC campaigns. Keywords your competitors rank for organically are often worth bidding on to capture sponsored placement as well, especially during product launches when organic rank has not yet been established.

Method 5: Amazon Search Term Report (For Advertisers)

If you are running Sponsored Products campaigns, Amazon provides a Search Term Report that shows exactly which customer search terms triggered your ads and led to clicks or conversions. This is real conversion data — not estimates — making it one of the most reliable ways to identify keywords that actually drive sales.

How to access and use the report

Go to Seller Central, then Reports, then Advertising Reports. Select “Search Term Report” and choose a date range of at least 14 days for statistically meaningful results. Download the report and sort by conversions or sales revenue rather than clicks — you want keywords that produce orders, not just traffic.

Auto campaigns are especially useful for keyword discovery when learning how to find keywords on Amazon. Let Amazon’s algorithm find converting search terms automatically, then move those terms into manual campaigns with higher bids and exact-match targeting. This auto-to-manual harvesting workflow should run every two weeks as a permanent part of your PPC management process.

Method 6: Google Tools for Amazon Keyword Ideas

While Amazon and Google are different search engines, Google’s keyword tools can surface product-related search terms that shoppers also use on Amazon. The overlap is significant because the same humans who search Google for product information often complete their purchase on Amazon.

Google Trends

Compare relative interest across keywords and identify seasonal patterns. If you sell outdoor furniture, Google Trends shows you that “patio furniture” peaks in April–May while “fire pit” peaks in September–October. This timing intelligence is critical for Amazon sales increase strategies — adding seasonal modifiers to your listing before demand peaks captures traffic that competitors who react late will miss.

Google Keyword Planner

While designed for Google Ads, Keyword Planner provides search volume data for product-related queries that frequently overlap with Amazon searches. Use it to estimate demand for keywords you have discovered through other methods and to find related terms you may have overlooked.

Organizing and Prioritizing Your Keywords

After using multiple methods, you will likely have a raw list of 200–500 or more keywords. You cannot target all of them equally — you need a prioritization system that separates high-impact terms from noise. This framework sorts every keyword into a clear tier with a specific placement assignment.

Understanding Amazon Best Sellers Rank helps you validate whether your keyword prioritization is translating into actual sales velocity once you implement the keywords.

Where to Place Your Keywords

Knowing how to find keywords on Amazon is only half the job. The other half is placing them correctly across every element of your listing so the algorithm indexes them and shoppers find you.

Product title: Your top 3–5 keywords, with the highest-volume term placed first. Follow our Amazon product title optimization guide for character limits, formatting rules, and mobile-display considerations.

Bullet points: Secondary keywords woven naturally into benefit-driven copy. Each bullet should contain 1–2 keyword phrases while remaining readable and persuasive. See our Amazon bullet points best practices guide for formatting and keyword integration techniques.

Product description and A+ Content: Supporting and long-tail keywords within detailed product storytelling. A+ Content modules — comparison charts, lifestyle images with text overlays, feature highlights — provide natural placement opportunities for Tier 3 and Tier 4 keywords that would feel forced in bullet points.

Backend search terms: Everything that does not fit naturally in visible copy — misspellings, synonyms, abbreviations, Spanish translations, and alternative phrasings. Backend keywords are invisible to shoppers but fully indexed by the algorithm. See our Amazon backend keywords guide for the technical rules and character limits.

PPC campaigns: All Tier 1 and Tier 2 keywords as manual campaign targets with exact-match or phrase-match bidding. Understanding Amazon ACOS vs TACOS helps you set realistic performance benchmarks for each keyword group and evaluate whether your paid campaigns are supporting or cannibalizing your organic growth.

Common Mistakes When Finding Amazon Keywords

Starting with tools before understanding your customer. Tools generate lists, but only you know your customer’s language. Start by reading competitor reviews — the exact words customers use to describe products, praise features, or complain about shortcomings are often the best keywords. A customer who writes “finally a mat thick enough for my bad knees” just handed you the long-tail keyword “yoga mat for bad knees thick.”

Ignoring search intent. “Yoga mat” and “thick yoga mat for bad knees” have very different buyer intents. The second phrase converts at a much higher rate because it signals a specific need that your product either solves or does not. Prioritize keywords that match your product’s specific attributes and the problems it solves.

Copying competitors exactly. Use competitor analysis for inspiration, not duplication. Your product has unique features, materials, or design elements — find the keywords that highlight those differences rather than blending into the same search results with identical copy.

Researching once and forgetting. Amazon search behavior shifts constantly. New products enter the market, consumer trends change, and seasonal demand fluctuates. Re-run your keyword research quarterly at minimum, and always before major events like Prime Day, Black Friday, and the Q4 holiday season.

Chasing volume over relevance. A keyword with 50,000 monthly searches sounds attractive, but if it does not accurately describe your product, the traffic will not convert. Ten highly relevant keywords with 1,000 searches each will almost always outperform one irrelevant keyword with 50,000 searches in terms of actual revenue generated.

For sellers looking to rank Amazon products organically, knowing how to find keywords on Amazon is where that journey begins. And for those driving external traffic through influencer marketing, understanding which keywords your listing targets helps ensure that the traffic you send from social media actually converts once it reaches your Amazon page.
