How to Choose the Best Keyword Research Tool for Amazon?
To choose the best keyword research tool for Amazon sellers, you need to prioritize accuracy and affordability. These are the key factors that help you discover the most popular search terms used by buyers, allowing you to optimize your Amazon SEO and drive sales effectively.
Accuracy ensures that the keyword data you’re using is reliable, while affordability makes sure you’re getting the best value without overspending.
Ease of use is also a helpful consideration, as a well-designed interface can save time.
For global sellers, marketplace support is important — choosing a tool that covers multiple regions allows you to optimize listings across various Amazon marketplaces.
Just like optimizing for a search engine, remember that Amazon SEO is a long-term strategy.
With the right tool and consistent effort, you can ensure your products are seen by the right audience.
Here are the best tools to help you succeed:
Helium 10: The Best Amazon Keyword Research Tool
Helium 10 is the gold standard when it comes to Amazon keyword research, thanks to its robust feature set that caters to both beginners and advanced sellers.
Its two main keyword research tools, Magnet and Cerebro, make it the go-to platform for anyone serious about improving their Amazon business.
Magnet is excellent for seed keyword research, allowing you to explore new keyword opportunities with in-depth filtering options like search volume, title density, and the Magnet IQ Score. These features help you find keywords with low competition but high potential, giving you the edge in crowded markets.
Cerebro is another standout feature that focuses on competitor analysis. By inputting a competitor’s ASIN, you can reverse-engineer their keyword strategy and discover which high-traffic keywords are driving their sales. This is invaluable for refining your own listings and staying one step ahead of your competition.
Helium 10 also offers unparalleled flexibility with support for 14 different Amazon marketplaces, ensuring that international sellers can leverage its features no matter where they operate.
While the Starter plan limits some keyword research functionalities, upgrading to the Platinum or Diamond plans unlocks the full power of these tools.
- Two powerful Amazon keyword tools with accurate data
- Covers 14 Amazon marketplaces
- Seed keyword and ASIN-based research options
- Limited keyword research on the Starter plan
Our Verdict: Helium 10’s Magnet and Cerebro make it unbeatable for serious sellers who want comprehensive Amazon keyword research across multiple marketplaces.
Jungle Scout: Best for Global Sellers and Ease of Use
Jungle Scout has earned its reputation as a go-to software for Amazon sellers, particularly those looking to expand into international markets.
Keyword Scout, the platform’s flagship keyword research tool, lets you input seed keywords and receive detailed metrics like search volume, competition level, and PPC bid estimates. This is invaluable for anyone building a PPC campaign or looking for high-ranking keywords in Amazon’s organic search results.
Similarly to Helium 10, Jungle Scout also offers a reverse ASIN feature. This tool allows you to plug in a competitor’s ASIN and see which keywords are driving their success. By understanding which keywords are working for top-performing products, you can tailor your own listings or PPC advertising campaigns to be more competitive.
Jungle Scout’s Rank Tracker is another highly valuable feature, allowing you to monitor the performance of multiple keywords over time. This feature gives you a clear view of how your chosen keywords are performing, making it easier to adjust your strategy as needed.
Unlike some of its competitors, Jungle Scout supports keyword research across 10 marketplaces, making it a versatile choice for sellers with international ambitions.
While there are some limitations in the lower-tier plans, Jungle Scout remains an excellent choice for sellers focused on both seed keyword research and competitor analysis.
- Reverse ASIN search and keyword cloud features
- Intuitive interface and Rank Tracker
- Supports 10 Amazon marketplaces
- Works for fewer marketplaces than Helium 10
- Some limits on lower-tier plans
Our Verdict: Jungle Scout is a great option for seed keyword research and reverse ASIN tracking, especially for sellers targeting multiple international markets.
AMZScout: Budget-Friendly with Essential Keyword Tools
AMZScout stands out as a budget-friendly option for sellers who want solid keyword research tools without the bells and whistles of pricier platforms.
Its Reverse ASIN Lookup and Keyword Tracker tools are reliable and easy to use, making them ideal for sellers who want to uncover high-performing keywords and track their rankings without diving into overly complex features.
For those looking to monitor trends, AMZScout’s simple interface gets the job done.
The Amazon Keyword Search feature allows you to enter specific search terms and identify how frequently they’re being used. This can help sellers stay on top of trending keywords in their niche, which is especially important for keeping listings fresh and competitive.
While AMZScout doesn’t offer the advanced filters available in Helium 10 or Jungle Scout, it compensates with straightforward, easy-to-navigate features.
Although AMZScout doesn’t support as many marketplaces as Helium 10 or MerchantWords, it covers 12 major Amazon markets, giving sellers solid international reach.
With 1,500 keyword searches available each month, it’s a particularly good option for small-to-medium-sized sellers who don’t need exhaustive daily research but still want to stay competitive.
- Affordable keyword research tool
- Reverse ASIN search and seed keyword research
- Works across 12 Amazon marketplaces
- Lacks advanced filtering
Our Verdict: AMZScout is a reliable, affordable choice for sellers who need essential keyword insights without the extra complexity.
ZonGuru: Niche Optimization and Focused Keyword Research
ZonGuru is an excellent software for sellers focused on niche keyword optimization.
While it doesn’t offer seed keyword research like Helium 10 or Jungle Scout, its Keywords on Fire tool makes up for this by delivering highly targeted keyword suggestions.
Instead of generating a broad range of keywords, Keywords on Fire asks for a competitor ASIN and then returns niche-specific keywords. This approach allows you to optimize your listings based on what’s already working for top competitors in your category.
A key advantage of ZonGuru is its focus on listing optimization. Once you have a targeted set of keywords, ZonGuru helps you refine your product listings by suggesting keyword placements in titles, bullet points, and descriptions. This can dramatically improve your product’s visibility on Amazon, especially in competitive categories where niche keywords make all the difference.
However, one downside is that ZonGuru places limits on Amazon keyword tool usage, even in its higher-tier plans. While this might not be a dealbreaker for sellers who don’t need extensive daily searches, it can be limiting if you’re managingmultiple product lines or need more frequent access.
Despite this, ZonGuru supports 10 marketplaces and offers a Chrome extension for lightweight keyword research, making it a practical tool for sellers focused on niche products.
- Works across 10 Amazon marketplaces
- Niche-focused keyword suggestions
- Chrome extension for lightweight keyword research
- Usage limits on all plans
- No seed keyword research tool
Our Verdict: ZonGuru works well for sellers focused on optimizing existing listings but falls short in broad keyword research.
Zoof: Best for Amazon US Sellers
Zoof is designed specifically for Amazon US sellers, making it a strong choice for those focused on that market.
Its Recon tool allows sellers to conduct in-depth seed keyword research, providing both short- and long-tail keyword suggestions along with data on total and average search volume. These insights can help you refine your listings to capture more traffic and improve conversions, especially within the US market.
In addition to Recon, Zoof’s Spy tool lets you analyze competitor keywords by simply entering their ASINs. This feature provides a breakdown of the top-ranking keywords driving your competitors’ sales, allowing you to either incorporate these into your own listings or adjust your advertising campaigns. It’s particularly useful for sellers looking to outperform rivals in their specific niche.
While Zoof offers comprehensive features for the US market, its biggest limitation is its lack of support for international marketplaces. For sellers looking to expand globally, other software like Helium 10 or Jungle Scout would be a better fit.
However, for US-based sellers who want to get the most out of their Amazon listings, Zoof remains a powerful, budget-friendly option.
- Offers seed keyword research and reverse ASIN tool
- No restrictions on keyword research tools in higher-tier plans
- Only supports Amazon US
- No Chrome extension support for keyword research
Our Verdict: Zoof is a solid choice for sellers focused solely on the US market but isn’t ideal for those targeting multiple marketplaces.
MerchantWords: Best for Discovering Emerging Keyword Trends
MerchantWords is a standout tool for sellers who want to discover emerging trends across multiple marketplaces.
With its Emerging Trends feature, sellers can spot rising keywords and product niches, helping them stay competitive in fast-changing markets.
Classic Search, MerchantWords’ top feature, gives sellers access to real Amazon shopper search data, including search volume and seasonal trends. This insight helps sellers plan for seasonal peaks and optimize their listings accordingly.
For those selling globally, MerchantWords covers 11 Amazon marketplaces, providing a decent level of international reach and ensuring that sellers can adapt to different market trends.
However, MerchantWords’ lower-tier plans come with search limits, which might feel restrictive for heavy users. To unlock unlimited searches and access to all features, you’ll need the Platinum plan, which can be on the pricier side compared to other tools. But for sellers looking to tap into emerging trends and niche markets, MerchantWords remains an excellent choice.
- Keyword research across 11 marketplaces
- Focus on emerging keyword trends
- Search limits on lower-tier plans
- Lacks advanced filtering options
Our Verdict: MerchantWords is ideal for sellers looking to uncover new keyword trends, but higher-tier plans are necessary for unrestricted access.
SellerApp: A Strong Choice for Global Sellers
SellerApp is a versatile software packed with features that help you stay ahead in keyword research.
Its Keyword Tool provides detailed data on search trends, competition, and volume, making it easier to optimize your listings and improve visibility. It’s especially powerful for sellers targeting a global audience, as it supports keyword tracking across 16 Amazon marketplaces.
One of SellerApp’s standout features is its Reverse ASIN tool. By analyzing your competitors’ keywords, you can gain valuable insights into what’s working for them and use that to boost your own listings or PPC campaigns. This gives you a competitive edge, especially when operating in larger markets.
The downside? SellerApp’s pricing is on the higher side compared to other software, and you need to export keyword data for deeper analysis, which can feel a bit clunky.
Still, with its wide marketplace coverage and in-depth tracking capabilities, SellerApp is an excellent choice for those aiming to grow their business internationally and are ready to invest in more advanced tools.
- Strong keyword research and tracking across 16 marketplaces
- Competitor insights with the Reverse ASIN feature
- Excellent for global sellers looking to scale
- Higher price compared to some alternatives
- Requires data export for in-depth analysis
Our Verdict: SellerApp is perfect for sellers targeting multiple marketplaces globally. Its rich feature set is worth the investment, especially if you need serious keyword tracking across different regions.
DataDive: Best for Keyword Tracking and Strategic Clustering
DataDive is a powerful tool for Amazon sellers who want to take their keyword research to the next level. It offers a smart combination of keyword tracking, clustering, and competitor analysis.
The Rank Radar feature is a game-changer for tracking keyword performance. It provides daily updates on how your keywords rank organically and how PPC campaigns influence those rankings. With options to add notes and highlights, Rank Radar helps you monitor progress and quickly adapt to changes in the marketplace.
The Master Keyword List compiles all the important keywords driving sales in your niche, showing you where competitors rank for each one. This insight makes it easier to target the right terms and refine your strategy.
DataDive’s Roots Tab organizes keywords into clusters by shared root words, like “nonstick” or “egg pan,” and calculates their combined search volume. This approach simplifies keyword prioritization, helping you focus on the clusters with the highest traffic potential.
Another standout feature is Outlier Keywords, which highlights high-volume but low-competition terms. These hidden gems give you the chance to rank quickly and capture untapped traffic with minimal effort.
With seamless integration with Jungle Scout’s API, DataDive combines accurate keyword data with advanced features that focus on delivering actionable insights.
- Tracks keyword rankings daily for better performance insights
- Finds gaps in competitor strategies to improve targeting
- Clusters related keywords to make research faster and easier
- Clusters related keywords to make research faster and easier
SmartScout: Best for Competitor Insights and Keyword Targeting
SmartScout is a powerful tool for Amazon sellers who want to refine their keyword strategies and gain an edge over the competition.
Its straightforward features are designed to uncover high-performing keywords and deliver actionable insights without breaking the bank.
The Keyword Detective tool is a key highlight, combining rank tracking, relevancy analysis, and search term intent to identify the most effective keywords for your listings. By analyzing keyword performance, this tool ensures you focus on terms that drive visibility and conversions.
SmartScout’s Ad Spy feature takes keyword research to the next level by analyzing competitors’ PPC campaigns. By uncovering the keywords they target in their ads, you can refine your strategy and identify untapped opportunities.
SmartScout offers a simpler, more affordable pricing structure compared to larger suites like Helium 10, making it an excellent choice for sellers who want focused keyword tools without the extra costs.
- Tracks top-performing keywords and uncovers valuable insights from competitors' PPC campaigns
- User-friendly design makes research quick and easy
- Budget-friendly pricing for sellers of all levels
- Less comprehensive than tools designed for large-scale sellers
SellerSprite: Best for Market-Focused Keyword Research
SellerSprite blends keyword research with market analysis, making it ideal for sellers aiming to optimize listings and uncover hidden opportunities.
Its Keyword Mining feature captures past and current Amazon buying trends, helping sellers identify valuable keywords to boost conversions, refine backend terms, and improve PPC performance.
The tool’s Keyword Research functionality connects keywords to specific niche markets, providing insights into market demand and allowing sellers to create unique, non-homogenized product strategies.
For tracking performance, its Keyword Tracker monitors keyword rankings over time, while the Reverse ASIN feature reveals competitors’ keyword strategies to help refine your listings.
SellerSprite supports 9 Amazon marketplaces, which is lower than competitors like Helium 10 or Jungle Scout. However, it makes up for this with its budget-friendly pricing and practical tools that are easy to use for sellers of all levels.
- Captures Amazon buying trends for smarter keyword strategies
- Combines keyword research with market demand insights
- Tracks keyword performance with a straightforward interface
- Budget-friendly pricing suitable for most sellers
