7 Best Amazon Keyword Research Tools in 2025

Did you know that 70% of Amazon customers never click past the first page of results? That means finding the right keywords can make or break your success on Amazon. With the right Amazon keyword research tools, you can uncover high-traffic, low-competition keywords that boost visibility and sales.

But not all keyword tools are created equal.

Some focus on advanced analytics and in-depth filters, while others specialize in helping new sellers just starting with keyword research. Whether you’re looking for precise analysis, affordability, or ease of use, the right tool depends on your needs and budget.

To create this guide, we evaluated over a dozen popular Amazon keyword research tools. Our final list includes tools tailored to sellers of all experience levels. Whether you’re a seasoned professional or just starting out, there’s a tool here that fits your needs. Here’s what we discovered.

• Helium 10: for an all-in-one keyword tool

• AMZScout: for the easiest-to-use keyword tool
• Merchant Words: for international sellers

What makes the best Amazon keyword research tool?

In order to create an accurate list of the best keyword research tools, we needed to define the criteria we were looking for. Here are some of the most important features we focused on when choosing the best keyword tools for Amazon sellers.

• Accuracy: The most important feature in a keyword tool is accuracy. It doesn’t matter how great the UI is or how many filters it has if the data it provides is inaccurate. We tested and compared the keyword results from each tool on our list to ensure that the data was accurate and all the top keywords were included.
• Easy to Use: This is an important factor for any software tool we feature on Levi’s Toolbox. Software should make your life as an Amazon seller easier, not more complicated. For our list, we included tools that are easy to learn and use without spending hours watching instructional videos or reading how-to guides.
• Customization: Amazon keyword research comes in many forms. You may want to improve your SEO, research a new product or niche, or optimize your PPC campaigns. It’s important that your keyword tool can be used for any aspect of keyword research.
• Value: Software tools can be expensive. Depending on where you are in your seller journey, paying for a premium tool may or may not be possible. For our list, we included products that range from completely free to top-of-the-line Amazon keyword research tools.

The best Amazon keyword research tools at a glance

Best all-in-one Amazon keyword research tool

Helium 10

Helium 10 Pros:

• Most in-depth keyword list and filters
• Detailed competitor keyword research
• All-in-one platform with over 20+ tools

Helium 10 Cons:

• Premium price
• Steeper learning curve

Helium 10 is one of the most well-known names among Amazon sellers today. With over 2 million active users, it has built a strong reputation as a go-to platform for serious sellers looking to scale their business. This is especially true in the area of keyword research.

Helium 10’s keyword tool, Cerebro, is a reverse ASIN tool. This means that you input up to 10 ASINs, and Cerebro will provide a full list of every keyword that the listing ranks for. While many tools on our list use this method, what separates Helium 10 is the sheer number of keywords it generates. For most of our tests, Helium 10 generated around 10 times more keywords than competitors.

More than just keyword generation, Helium 10 also includes some of the best filters and metrics to find the right keywords for your needs. Results like search volume, keyword sales, competitor performance score, sponsored rank, and many more make it easy to sort and filter the long list of keywords. We particularly liked the pre-built “Top” and “Opportunity” keyword filters that make it easy to find the top-performing keywords and lower competition keywords, respectively.

However, Helium 10 is much more than an Amazon keyword research tool. Their subscription also includes tools like:

• Black Box: An in-depth product research tool with a significant number of filters and metrics
• X-Ray: Detailed product information and sales data directly from the Amazon page
• Refund Genie: Amazon refund management software to automate your FBA reimbursements
• Frankenstein: A tool to clean up and organize your keyword lists
• Listing Optimization: Improve your product listings, find new keywords, and study your competitors’ listings with the help of AI

Although we highly recommend Helium 10, it may not be the right fit for every seller. To get full access to Cerebro and their other keyword tools, you need their Platinum Plan, which is $99/month and may be expensive for some sellers. A more affordable option is their starter plan for $39/month; however, this plan is much more limited.

If you have the budget and are looking for a premium tool, Helium 10 is arguably the most comprehensive and full-featured Amazon keyword research tool on our list.

Free Trial: Helium 10 offers a 7-day free trial, no payment method required.

Helium 10 Pricing: The Starter Plan ($39/month) includes limited usage of keyword and product research tools. The Platinum Plan ($99/month) adds several additional features, including their complete suite of keyword tools. Finally, the Diamond plan ($279/month) includes keyword tracking, AI-powered advertising features, and several other advanced tools.

Best Amazon keyword tool for advanced research and competitor analysis

Data Dive

Data Dive Pros:

• Speed and optimization focus
• Detailed competitor keyword research
• Includes additional AI listing builder and product research tools

Data Dive Cons:

• Steeper learning curve
• UI can be overwhelming

Much like the name suggests, Data Dive is an Amazon keyword research tool with a focus on in-depth data analysis. The various charts, graphs, and columns include detailed information on competitors, PPC, relevancy scores, organic search volume, and so much more.

Another reverse ASIN tool, Data Dive, starts by asking you to input 10-15 competitor ASINs. From here, it will generate a keyword list containing all the top keywords from each listing. Keywords are conveniently organized into three lists: master, outlier, and residue. Master keywords are the hyper-relevant keywords you will want to include in your listing, outliers are search terms that may or may not be relevant but could provide opportunities, and residue keywords are irrelevant and can be ignored.

For each keyword, Data Dive can display a detailed list of information, including estimated PPC bids, a relevancy score, and the organic rankings for each of your competitors. Personally, I found the data easy to read, but I feel it could be overwhelming for some users. The color-coded results are a nice touch and make it a bit easier to get a grasp of things at a glance.

Besides keyword research, a Data Dive subscription also includes:

• Listing Builder: An AI tool that can help you create an SEO optimized product listing
• Product Scorecard: Analyze potential product ideas to determine if they’re worth launching
• AI Product Brief: Use AI to analyze product reviews and find ways to innovate on existing products
• Niche Dive: Quickly discover the top competitors for any product directly from the Amazon product page

If you’re a data-driven seller looking for an advanced Amazon keyword research tool, we highly recommend giving Data Dive a try.

Free Trial: Unfortunately, Data Dive does not offer a free trial.

Data Dive Pricing: The Starter plan ($39/month) includes 100 monthly keyword searches and five uses of the AI listing tool. The Standard plan ($149/month) increases that to 1,000 monthly searches and unlocks several additional features. Finally, the Enterprise plan ($490/month) is designed for larger brands that need higher limits and advanced capabilities.

Best value keyword research tool

ZonGuru

ZonGuru Pros:

• Affordable Pricing (and free trial)
• Easy-to-use for new sellers
• Unique filters and metrics

ZonGuru Cons:

• Fewer tools than other competitors
• No keyword tracking with cheaper plans

ZonGuru’s Keywords on Fire is an accessible and affordable option for Amazon sellers, especially those just starting out. With its user-friendly interface and streamlined approach, ZonGuru focuses on providing valuable keyword insights without overwhelming new users.

Often overlooked compared to tools like Helium 10 or Jungle Scout, ZonGuru offers a suite of tools designed to help Amazon sellers in all aspects of their business. The company has always had a seller-first approach, and many of its design decisions make this very clear.

ZonGuru stands out with unique metrics designed to simplify keyword research, making it more approachable for new sellers. In addition to standard data like search volume and sales, ZonGuru introduces two standout columns: ZG Score and ZG Launch. The ZG Score, rated out of 100, evaluates how valuable a keyword is for your listing. Meanwhile, ZG Launch estimates the number of daily sales needed to rank on page one for a specific keyword. These tools make keyword analysis easier to grasp for new sellers or those less comfortable with complex data.

Although it doesn’t include as many features as our previous two entries, ZonGuru offers a nice selection of tools and metrics at a very affordable price point.

ZonGuru offers two options for accessing its Amazon keyword research tool. You can subscribe to one of their standard plans, which includes their full suite of Amazon seller tools. Alternatively, you can opt for their keyword tool-only plan for just $19 per month.

Free Trial: ZonGuru offers a 7-day free trial with both their Researcher and Seller plans

ZonGuru Pricing: ZonGuru has two payment plans. The Researcher Plan is $49/month ($29/month annually), and the Seller Plan is $79/month ($49/month annually), which includes higher usage limits and several additional tools.

Best Amazon keyword tool for new sellers

Jungle Scout

Jungle Scout Pros:

• Variety of metrics to filter keywords
• Very beginner-friendly platform
• Includes over a dozen additional tools

Jungle Scout Cons:

• Cheaper plans only include 1 month of keyword history
• Fewer potential keywords than some competitors

Jungle Scout remains a go-to Amazon keyword research tool, especially for sellers looking to combine product research with keyword insights. Its well-rounded suite of tools includes keyword research, niche validation, sales analytics, and competitor analysis, all in one platform.

Starting with either a base keyword or an ASIN, their Keyword Scout tool allows you to find and filter all the top keywords for a potential product. Although we found some of the filter names confusing, Jungle Scout’s UI is generally very good. The keyword results page includes a lot of information, and it is very easy to hide or show columns based on the data you want to analyze.

For sellers focused on product research, their Opportunity Finder tool is a standout feature. This tool lets you explore new niches by using keywords to locate trending sub-categories or low-competition products. Pair this with the keyword tool’s filtering options, and you can quickly narrow down your search by metrics like search volume, competition, and seasonality.

While it doesn’t deliver the exhaustive keyword lists that tools like Helium 10 might, Jungle Scout excels in offering actionable data with an intuitive design. The platform also comes packed with over a dozen additional tools, from listing optimization to inventory management, making it ideal for sellers who want a multi-functional toolkit.

One limitation to note is that lower-tier plans cap users at one month of keyword history. This makes it impossible to do any historical keyword research or spot emerging market trends. To access a year of keyword history, users need to have their Growth Accelerator plan, which is currently $79/month.

Free Trial: Jungle Scout does not offer a free trial. However, they do provide a 7-day money-back guarantee with all of their monthly plans.

Jungle Scout Pricing: The Starter plan ($49/month) includes 50 monthly keyword searches and one month of historical keyword data. The Growth Accelerator plan ($79/month) increases that to 250 monthly searches, one year of historical data, and access to PPC-related keyword data. Finally, the Brand Owner plan ($149/month) offers unlimited keyword lookups and two years of historical data.

Best Amazon keyword tool for international sellers

Merchant Words

Merchant Words Pros:

• Robust suite of keyword tools
• Local keyword data for all Amazon marketplaces
• Excellent UI and ease-of-use

Merchant Words Cons:

• Premium pricing for regional marketplaces
• No additional tools besides keyword research

Merchant Words is a standout Amazon keyword research tool for sellers prioritizing in-depth keyword research and marketplace diversity. Its clean interface and intuitive design make it an excellent option for sellers who want powerful keyword insights without a steep learning curve.

The platform has been around since 2013, when it first started collecting Amazon keyword data. Since then, the number of tools has expanded greatly, and they currently have nine unique keyword-related tools. These tools cover reverse ASIN lookup, keyword trends, collections, complementary keywords, market insights, and more.

The UI and design are excellent as each tool flows seamlessly into the next. One of our favorite features was the Keyword Explorer. This is essentially your master keyword list that can be quickly filtered by word count. The tool itself is always accessible from a pop-out sidebar on the right side of the screen. This makes it very easy to edit and update your keyword list on the fly as you move between each tool.

Another standout feature is their local keyword data for all Amazon marketplaces. While most tools on our list work internationally, we prefer Merchant Words for international sellers. From our research, their independent keyword data offered the highest number of localized, accurate search terms for overseas markets.

Merchant Words stands out as a top-tier tool for keyword research due to its dedicated focus on this area. However, its singular role might not appeal to budget-conscious sellers who need a broader range of features. For those seeking an all-in-one solution, software suites like ZonGuru, Jungle Scout, or Helium 10 may offer better value by combining keyword research with other essential tools in a single subscription.

Overall, if you are an experienced seller looking for a more comprehensive keyword tool, we highly recommend giving Merchant Words a try.

Free Trial: Merchant Words does not offer a free trial at this time.

MerchantWords Pricing: There are four monthly plans available, starting with the Silver plan at $35/month, which includes access to one marketplace and 500 keyword searches per month. The other plans include Gold ($79/month) with 1,000 monthly searches, Platinum ($149/month) with unlimited searches, and Enterprise ($749/month), which is designed for large international businesses.

Easiest to use Amazon keyword research tool

AMZ Scout

AMZ Scout Pros:

• Very simple/easy to use
• Includes product research tools and keyword tracking
• Clear pricing plans

AMZ Scout Cons:

• Very limited filters and metrics
• Not as feature-rich as many competitors

The easiest-to-use keyword tool on our list is AMZ Scout. Although most well-known for their excellent Chrome extension and product research tool, AMZ Scout also includes an Amazon keyword research tool with their Seller Bundle.

Unlike many tools on our list, AMZ Scout uses a stripped-down UI with a very simple design. This makes it very approachable for beginners, as it doesn’t include many of the advanced filters included with most keyword tools.

To start researching keywords, sellers can either input a product name or ASIN in order to get a list of keywords. The data provided shows relevance, search volume, organic and sponsored rank, as well as a few additional metrics. Each column can be easily sorted, and it is very simple to create a list of potential keywords.

Unfortunately, for more data-focused sellers, AMZ Scout leaves a lot to be desired. The keyword filters are quite limited and only include search volume and number of words as options. It also lacks tools for competitor keyword research as well as more advanced keyword analysis.

If you are looking for a simple, easy-to-use keyword tool, AMZ Scout may be the right option for you.

Free Trial: AMZScout offers a free trial with limited use of both their keyword and product research tools. This includes 5 product searches and 3 Reverse ASIN keyword searches.

AMZ Scout Pricing: The AMZScout AI Bundle is their only plan at $59.99/month, $169.99 for 3 months, or $399.99 for a one-year subscription.

Best Amazon keyword tool for PPC-focused sellers

SellerApp

SellerApp Pros

• Connects keyword research with PPC data for better targeting
• Uses real-time data directly from Amazon’s API for better accuracy
• Rates listings for keyword use with a custom Listing Quality Index (LQI) metric

SellerApp Cons

• Has a bit of a learning curve
• Search limits on lower-priced plans

If you’re looking for a tool that combines keyword research with ad optimization, SellerApp may be for you. With a suite of over 10 tools, including ad automation and keyword tracking, SellerApp is positioned as a multipurpose Amazon seller software that specializes in Amazon PPC and keyword research.

Their main keyword tool is super easy to use. To get started, you simply need to enter a basic keyword related to your product, called a seed term, and the tool will pull up thousands of ideas, along with details on search volume, CPC, and my favorite, conversion rates, plus estimated monthly orders. This way, you can target keywords that lead to real purchases and not just clicks. SellerApp also includes a Reverse ASIN option that lets you enter competitor ASINs to find out which keywords they rank for, similar to tools like Helium 10 or Data Dive.

What sets SellerApp apart from our other entries is the way it mixes keyword data into its ad management tools. The PPC features handle bidding adjustments and campaign optimizations by pulling data directly from your keyword research, so you can avoid switching between different tools. Personally, I found the ability to push keywords directly from your keyword lists into your ad campaigns to be a huge time saver.

It’s also worth mentioning that SellerApp includes a Listing Quality Index score that you can use to optimize your product listings. This metric measures how well you have placed keywords on your product pages and offers straightforward tips on how to improve your SEO performance for better placements in search results.

With all of this said, no tool fits everyone, and SellerApp is a tool I wouldn’t recommend if you’re not actively advertising on Amazon. Brand-new sellers on a budget might want to focus on a more all-in-one tool like Jungle Scout or Helium 10, which have more features and resources available.

Free Trial: 7-day free trial on paid plans (credit card required). SellerApp also offers a free monthly plan with limited keyword searches and tracking.

Pricing: The Pro Plan starts at $99/month but scales with ad spend, monthly revenue, or number of ASINs. The higher-tier plan starts around $250 per month and unlocks full ad automation and higher keyword limits.

The Best Free Amazon Keyword Tools in 2025

If you’re new to selling on Amazon and don’t want to invest in a paid keyword tool, there are several free methods you can use to find keywords for your listings or ad campaigns. These tools may not have the features and filter options that software like Helium 10 or Data Dive offer, but they can be an excellent starting point and a great way to find the most relevant keywords for your product.

Here are five of the best free Amazon keyword tools available in 2025.

Product Opportunity Explorer
You might be surprised to know that one of the best free tools is made by Amazon itself. The Product Opportunity Explorer, available inside Seller Central, is a free resource for both keyword and product research. By selecting a niche, you can find the top-performing keywords with metrics like search volume, click share, and conversion data. The best part of this tool is that it uses real Amazon search data rather than estimates, making it the most accurate free resource available.

While you won’t have access to as many keywords as you’d find with a paid tool, you will be able to create a list of the top keywords for any niche on Amazon based on the most accurate data available. In my opinion, this is the best free data source available for Amazon sellers

Ahrefs Amazon Keyword Tool
Ahrefs offers a dedicated Amazon keyword tool that uses real search data to show keyword difficulty, search volume, and related terms. It’s intuitive, fast, and especially good at surfacing high-traffic keywords that can be easy to overlook. The free version is limited, but it’s still useful for quick research sessions when you need broad keyword ideas.

Amazon Autocomplete
Sometimes the simplest solutions are the most effective. Typing a product or phrase into Amazon’s search bar and writing down the autocomplete suggestions can be a great way to find what real shoppers are actively searching for. Each suggestion is based on real user data, which makes it incredibly relevant. Even with paid software, I still sometimes use this method to brainstorm product title ideas or long-tail keywords.

Keyword Tool Dominator
Keyword Tool Dominator is a lightweight, browser-based tool that pulls hundreds of keyword suggestions from Amazon’s autocomplete system. It’s a faster, more automated version of manual research. You get two free searches per day before it requires payment.

Keywords Everywhere
Keywords Everywhere is a browser extension that adds keyword data next to your web searches. While it’s primarily used for Google, the Amazon integration displays search volume, CPC, competition, and trend data underneath any search term on Amazon and also within the auto-suggestions.

Keep in mind that all of the data displayed comes from Google’s Keyword Planner and not Amazon, which means that you shouldn’t rely too much on the exact numbers. However, it’s still a great free tool that can help you see how keywords compare in terms of search volume and competition.

Free keyword tools won’t give you the same depth or flexibility as premium options, but they can still get the job done. My recommendation is to use multiple free tools at once to cover the most ground. Once you start to see some success, then you can consider transitioning to one of the fully featured tools included on our list.
