Best Amazon Keyword Tools for 2026

TL;DR Helium 10 is the strongest choice for active FBA sellers running PPC alongside organic. Jungle Scout is the cleanest entry point for new sellers. AMZScout covers the essentials at a lower monthly cost. Everything else on this list fills a specific gap or serves a particular situation.

The three tools most FBA sellers actually need are Helium 10, Jungle Scout, and AMZScout. Helium 10 covers the most ground if you run PPC campaigns alongside organic listings and research across multiple categories. Jungle Scout is the better starting point if you are launching your first product and want clean, readable data without a steep learning curve. AMZScout handles the core jobs at a lower monthly cost.

The right tool depends on where you are in your selling journey. A seller validating a first product has different needs than a brand managing 200 SKUs across three categories. This guide covers ten tools by use case, not just by feature list.

One rule applies to every tool below. Use Amazon-native search data, not Google data. Amazon shoppers type shorter, more specific queries with purchase intent. Google volume captures a much wider mix of informational and research traffic. High Google volume for a keyword does not mean high Amazon buyer traffic. For a deeper look at how keyword research fits your overall listing strategy, see our guide to Amazon keyword research.

Quick Comparison

 What to Look for Before You Commit

Amazon-native data is the first thing to check. Tools that source keyword volume from Google Ads rather than Amazon search give you the wrong signals. These are different platforms with different buyer behavior. A keyword that pulls 50,000 monthly searches on Google might barely register on Amazon. Look for tools that explicitly pull data from Amazon’s own search database.

Reverse ASIN lookup matters more than most sellers realise. Paste a competitor’s ASIN and get back every keyword their listing ranks for, organically and through sponsored placements. You skip weeks of guesswork and go straight to terms that are already converting in your category. All ten tools on this list include it. Usage limits vary significantly by plan tier, so check those before committing. For more on using those keywords to fuel your paid campaigns, see our guide to finding profitable keywords for PPC.

Search volume accuracy is worth understanding before you act on any number. No third-party tool has direct access to Amazon’s internal search data. Volume estimates across different tools can diverge by 30 to 40 percent for the same keyword. Treat volume as a directional signal (higher versus lower), not an exact count. For your most important terms, cross-reference against the Search Terms report inside Seller Central, which reflects real impression data from your own listing. Amazon’s A10 algorithm weighs keyword relevance alongside conversion rate, so the terms that drive actual purchases matter more than raw volume.

Tracking and discovery are different jobs. Finding keywords is step one. Knowing whether your listing actually ranks for them week over week is step two. Some tools handle both well. Others are primarily discovery tools with basic tracking layered on top. Be clear on which job you need most before choosing a plan tier.

Budget fit matters more than feature count. The difference between a free plan and a full Helium 10 Diamond subscription is over $3,300 a year. Match your spend to your monthly revenue and the scale of your keyword work, not to the most impressive feature list.

The Best Amazon Keyword Tools

1. Helium 10

Helium 10 is the most complete Amazon keyword toolkit available. Two tools inside it do most of the work. Magnet generates keyword ideas from a seed phrase and surfaces related terms with volume, trend, and competitive data. Cerebro runs reverse ASIN lookups against any competitor listing and shows you every keyword that listing ranks for, organically and in sponsored placements.

Used together, they cover the full research workflow. Cerebro tells you what is already working in your category. Magnet finds terms your competitors have missed. Helium 10 also connects to listing optimization, PPC analytics, and inventory management, which is efficient if you want those jobs handled in one platform.

Helium 10 raised its prices in April 2026 and discontinued the Starter plan. The entry point for new users is now the Platinum plan at $99 per month with annual billing, or $129 per month on a monthly subscription. A limited free plan exists but restricts access to Cerebro and Magnet. A 7-day free trial on the Diamond plan is available with no credit card required. See Helium 10 for current plans.

2. Jungle Scout

Jungle Scout is the easiest tool on this list to start with. Keyword Scout, its dedicated keyword tool, returns search volume, trend data, and competitive ranking information in a format that is readable without a learning curve. The browser extension pulls data directly inside Amazon search pages, so you can research while you browse without switching between tabs.

Where Jungle Scout sits behind Helium 10 is depth. The reverse ASIN lookup and keyword tracking in Helium 10 are more granular. For a seller launching their first few products, that depth is often not necessary. For sellers managing a larger catalog or running significant PPC spend, Helium 10 pulls ahead.

Jungle Scout rebranded its plans to “Catalyst” in 2026. Pricing starts at $29 per month with annual billing (billed as $349 per year) for the Starter plan, or $49 per month on a monthly subscription. A 7-day money-back guarantee applies to all plans. See Jungle Scout Keyword Scout for a full feature breakdown.

3. AMZScout

AMZScout covers the three things most sellers need most: keyword research, reverse ASIN lookup, and product tracking. It does them at a lower monthly cost than either Helium 10 or Jungle Scout. The PRO Extension runs inside Amazon search results, giving you keyword volume, estimated sales, and competitive data without leaving the page.

Where AMZScout falls short is range. If you also need detailed PPC analytics, market share reporting, or frequent listing optimization, the gap compared to Helium 10 is significant. If keyword research and reverse ASIN lookup are the primary jobs, AMZScout handles them competently.

AMZScout supports 12 Amazon marketplaces. Pricing is available monthly, annually, and as a one-time lifetime purchase. A 7-day free trial and a 10-day money-back guarantee apply to all plans. Check current pricing at AMZScout before purchasing, as monthly costs have changed recently.

4. SmartScout

SmartScout approaches keyword research from a different angle. Where most tools start with a keyword and work outward, SmartScout starts with the category and works inward. It shows you which brands hold the most traffic in a subcategory, how that traffic distributes across competing products, and where market share shifts when competitors change pricing or launch new listings.

For sellers evaluating a new niche before entering it, that category-level view is genuinely useful. For sellers who already know their category and primarily need keyword volume and reverse ASIN data, SmartScout is more effective alongside a keyword-first tool than as a replacement for one. Entry plans start around $25 per month with a 7-day free trial. See SmartScout for current pricing.

5. SellerApp

SellerApp is built with PPC keyword work as a primary use case. It is a solid fit for sellers optimizing Sponsored Products campaigns who need keyword data that directly informs bid decisions. The free keyword research tool gives access to estimated search volume and CPC data without a subscription, useful for initial validation before committing to a paid plan.

The paid plans add keyword rank tracking, more granular volume data, and deeper PPC analytics. If your main focus is organic listing visibility rather than paid campaign performance, there are stronger options at a similar price. See SellerApp keyword tools for plan details.

6. DataHawk

DataHawk is an enterprise analytics platform. It is not a self-service subscription. Pricing is custom and requires a demo. It offers keyword tracking, category-level market share, share of voice, and cross-marketplace performance reporting across Amazon and Walmart, with dashboards that can be shared across teams without manual exports.

For individual sellers or small operations, DataHawk is not the right fit. For agencies managing multiple client accounts, or brands with large catalogs that need structured reporting beyond what Helium 10 or Jungle Scout provide, it is worth exploring. See DataHawk for enterprise pricing.

7. Google Keyword Planner

Google Keyword Planner is free. Type in a keyword and you get average monthly search volume, competition level, top-of-page bid data, and related keyword suggestions. For getting a rough sense of whether a topic has broad search demand, it is a useful starting point before spending money on a paid tool. See Google Keyword Planner to access it.

The limitation is the data source. Google Keyword Planner reflects what people search on Google, not on Amazon. A keyword with high Google volume can have minimal Amazon buyer traffic. Use it for topic-level research. For Amazon listing optimization and backend keyword selection, use a tool that sources data from Amazon search directly.

8. Amazon Keyword Tool (keywordtool.io)

Keywordtool.io has an Amazon-specific mode that pulls keyword suggestions from Amazon’s autocomplete data. You get search volume estimates, trend data, and CPC alongside related keyword suggestions. Basic lookups are available without an account. The full results require a paid subscription. See Amazon Keyword Tool for current plans.

The main appeal is the volume of autocomplete-derived suggestions, which surface longtail keyword variations that volume-first tools often miss. The limitation is cost relative to what you get. At the entry plan price, Jungle Scout or AMZScout offer more features for a similar investment.

9. Ahrefs

Ahrefs is primarily a web SEO tool with Amazon keyword functionality. That distinction matters. Its Amazon keyword data exists but is less detailed than what Helium 10 or Jungle Scout provide. The core strengths of Ahrefs are analyzing Google search rankings, backlink profiles, and content gaps. The case for including it is if you are also running a brand website or any off-Amazon content strategy. Pure-play FBA sellers with no off-Amazon presence will get better keyword data per dollar from any of the tools listed above. See Ahrefs for current plan pricing.

10. Merchant Words

Merchant Words has been building its Amazon keyword database for over a decade, and that shows most clearly in longtail keyword depth. It surfaces specific, lower-competition terms that volume-focused tools regularly miss. The Silver plan covers one marketplace, which keeps costs manageable for sellers focused on a single country. For sellers who want to complement a primary tool with deeper longtail coverage, Merchant Words adds real value. As a standalone primary tool, it lacks the reverse ASIN depth and tracking that active sellers need. See Merchant Words for current pricing.

Frequently Asked Questions

What is the best free Amazon keyword tool?

Helium 10 has the most capable free offering. The free plan includes limited monthly uses of Magnet and Cerebro, covering basic keyword discovery and reverse ASIN lookups. Google Keyword Planner is completely free but uses Google data rather than Amazon data, so use it for broad topic research only. SellerApp also has a free keyword search function that gives volume and CPC estimates without a subscription.

Is Helium 10 worth the cost for smaller sellers?

At $99 per month on annual billing, Helium 10 makes sense if you are actively launching new products or regularly optimizing several listings. If you are maintaining a stable catalog with minimal new keyword work, AMZScout or Jungle Scout cover the essentials at a lower monthly cost. The Starter plan was discontinued in April 2026, so the entry point is higher than it was a year ago.

Can I use Google Keyword Planner for Amazon SEO?

For understanding whether a topic has broad search demand, yes. For Amazon listing decisions, no. Google captures a much wider mix of informational and research searches than Amazon does. A keyword with strong Google volume can have minimal Amazon buyer traffic. For listing optimization and backend keyword selection, use a tool that sources data from Amazon search directly.

What is a reverse ASIN lookup and why does it matter?

A reverse ASIN lookup takes a competitor’s Amazon product identifier and returns every keyword their listing ranks for, both organically and through sponsored placements. It is the fastest way to find terms that buyers are already using to find similar products in your category, without starting your keyword list from scratch. Helium 10’s Cerebro, Jungle Scout’s Keyword Scout, and AMZScout all include it.

How often should I update my Amazon keyword research?

Review your top keywords at least quarterly. Do an immediate check after any notable ranking drop in Seller Central, before Q4 prep begins, or whenever a direct competitor launches a new product in your category. Keyword demand on Amazon shifts with seasonality and category trends. A term that performed well in January may need attention by October.

Final Thoughts

For most FBA sellers in 2026, the decision is not complicated. Helium 10 if you want the most complete toolset and run PPC alongside organic. Jungle Scout if you are earlier in your journey and want clean data without a steep learning curve. AMZScout if you want the core jobs done at a lower monthly cost. Everything else fills a specific gap or serves a particular situation.
