I’ve been running an online business for a few years, and finding the right tools hasn’t been easy. Initially, I struggled with keyword research until I discovered Helium 10 and MerchantWords.
Helium 10 impressed me with its all-in-one features to boost Amazon sales, while MerchantWords stood out for its simple keyword research.
I’ve spent time exploring both tools to see what works best. In this comparison, I’ll share my insights to help you choose the right tool for your journey, whether you’re starting or scaling up!
Helium 10 vs Merchant Words: Overview
About Helium 10:

Helium 10 is a powerful all-in-one software suite designed for Amazon sellers. I’ve used it myself, and it’s packed with over 20 tools that help with everything from product research to keyword optimization and inventory management.
It’s like having a Swiss Army knife for your online business.
If you’re finding profitable products with Black Box or spying on competitors’ keywords with Cerebro, it’s built to streamline and scale your Amazon game.
It started in 2015, and I’ve seen it grow into a go-to for sellers who want detailed data and actionable insights.
About MerchantWords:

MerchantWords, on the other hand, is more focused—it’s a keyword research tool that’s been around since 2012. I’ve found it super helpful for digging into what shoppers are searching for on Amazon.
It pulls from a massive database of over a billion search terms, giving you real customer insights to boost your listings. It’s simpler than Helium 10, zeroing in on keywords and trends rather than offering a full toolbox.
For me, it’s been a quick way to find high-value search terms and stay ahead of what’s trending. Both tools are solid, but they serve different needs depending on how deep you want to dive!

Why Should You Use a Keyword Research Tool?
Keyword research tools like Helium 10 and Merchant Words are valuable for Amazon sellers because they provide important data. This data helps sellers understand how to find and promote their products effectively.
Merchant Words has been gathering data for Amazon sellers since 2012, while Helium 10 started in 2015. They collect information about how many Amazon customers search for specific keywords.
This data is then shared with sellers so they can use it to improve their product sourcing and marketing strategies.
The data is based on billions of customer searches, so there’s a lot of information available for sellers to use. Overall, these tools help sellers make informed decisions about their products and reach more customers on Amazon.
How’s Data the Most Important to Online Sellers and Why Should You not Ignore it?
Data is like a secret weapon for online sellers. It tells them exactly what they need to know before they launch new products.
For example, if you want to sell something new but don’t know what will be popular, a keyword research tool can help. It shows you what people are searching for the most.
Using a tool like Helium 10 or Merchant Words gives you an advantage over competitors who aren’t using any data. Let’s say you’re interested in selling camping gear.
You can type “camping gear” into one of these tools and see how many people are searching for it. You’ll also see other related keywords. This helps you understand what camping gear products customers are looking for.
Without these tools, you’re relying on luck and guesswork. You might not do as well in business without data to guide you. While gut feelings can sometimes help, using data is usually better for your business in the long run.
Data Accuracy:
MerchantWords
MerchantWords claims to collect highly accurate keyword information directly from Amazon’s search bar. They assert that they analyze millions of search terms across various marketplaces and take pride in their precision.
However, I’ve heard feedback from some sellers—and observed myself—that the numbers aren’t always consistent.
For instance, I might find a keyword with a large search volume in MerchantWords, such as 200,000, but when I utilize it, my listing receives hardly any clicks. It’s not always reliable.
Helium 10
Helium 10 obtains its keyword information from Amazon as well, incorporating advanced technology and an extensive database to estimate search volumes and identify trends.
I appreciate its analytical approach, but it has its imperfections. For less common or niche keywords, I’ve noticed that the data can seem inaccurate.
For example, it might indicate that a keyword has 5,000 searches, yet my sales don’t support that claim—it has left me puzzled regarding its reliability for those more obscure terms.
How Do Helium 10 and Merchant Words Help Your Business?
Helium 10 and Merchant Words help your business in two main ways:
- Finding New Opportunities:
They help you discover what products people are searching for so you can launch new listings that match customer demand.
- Staying Updated:
They keep you informed about current trends in customer behavior and product popularity.
Now, you might be thinking, “How are Helium 10 and Merchant Words different?” I’ll compare them in terms of what they do well and where they might have some limitations.
Difference Between: Helium 10 vs Merchant Words
The main difference between Helium 10 and Merchant Words lies in the data they use.
Aspect | MerchantWords | Helium 10 |
---|---|---|
Keyword Search Estimates | Shows bigger numbers—like 211,600 searches for “chalk bag.” Feels like a wider market view. | Gives smaller, tighter estimates—like 6,232 for “chalk bag.” Claims accuracy through testing. |
Data Claims | Boasts the most accurate, massive keyword database. I’ve found it great for spotting trends. | Says its data matches or beats competitors. I trust it for solid, reliable insights. |
Inventory Management | No feature for this—it focuses on search data, not listing protection. | A lifesaver! Tracks stock, flags reorders, and handles shipments. Saved me from chaos. |

What I Like | Love how it opens up big keyword opportunities. Perfect for research. | Feels like a full toolbox—inventory, alerts, and more. Great for running my whole Amazon game. |
My Take
MerchantWords shines for keyword deep dives—those huge search numbers get me excited about possibilities. Helium 10, though, feels like my business partner, covering inventory and protection alongside keywords. Depends on what you need most!
Which Should You Trust?
Deciding which tool to trust depends on the data source you have more confidence in. Both Helium 10 and Merchant Words claim to provide the best data, so there are other factors to consider when making your decision.
MerchantWords has been in the business longer and gets its data directly from Amazon search trends. It focuses solely on Amazon and doesn’t use data from search engines like Google or Bing.
Helium 10, on the other hand, uses data from sources outside of Amazon, including pay-per-click landing data from sponsored products. This can be beneficial because products with more visibility through advertising are often more likely to be purchased.
It’s tough to determine which tool is more trustworthy. Some sellers might prefer Merchant Words because of its longer history and exclusive focus on Amazon data. Others might lean toward Helium 10 for its broader data sources and potentially more conservative figures.
Are Helium 10 and Merchant Words really easy to use?
Both Helium 10 and Merchant Words are user-friendly keyword research tools. To use them, you need to download the apps or browser extensions, enter your desired keyword, and get your data. You can also download the data and analyze the results further.
While people may debate about the differences in data accuracy, there’s no doubt that both tools are easy to use. So, if you’re looking for a simple tool, either Helium 10 or Merchant Words would be a great choice.

API of Helium 10 vs MerchantWords:
Helium 10 API
The Helium 10 API is like a backstage pass to Amazon data for your business. It’s an Application Programming Interface—fancy words for a tool that lets developers pull info from Helium 10’s platform and Amazon’s systems.
I’ve seen it work wonders for sellers who want to automate tasks or dig deeper into their stats. It ties into Amazon’s Marketplace Web Service (MWS) and Selling Partner API, so you can manage listings, grab keyword data, or track sales without clicking around all day.
For example, I could use it to fetch product trends from Black Box or competitor keywords from Cerebro—stuff that’d take hours manually.
You need a Helium 10 account, pick a plan, and generate an API key from their dashboard to get started. It’s powerful but technical—perfect if you’ve got a developer or some coding skills to make it sing.
For me, it’s like having a robot assistant to handle the heavy lifting.
MerchantWords API

The MerchantWords API is more focused—it’s all about keywords and shopper insights. It taps into their massive database of over a billion Amazon search terms, which I’ve found super useful for figuring out what buyers actually type into that search bar.
You can use it to pull keyword search volumes, see what ranks a product on page one, or spy on competitors’ terms.
I’ve played with their tools before, and this API feels like an extension of that—letting you grab data like how often “yoga mat” gets searched or what phrases push an ASIN to the top.
It’s less about running your whole business and more about nailing keyword strategy. You’d need to sign up with MerchantWords, and they pitch it for “ranking keywords and metrics for thousands of Amazon products.”
It’s straightforward if you’re obsessed with keywords like I am, but it’s not as broad as Helium 10’s toolbox.
Which Research Tool is Better?
Deciding which keyword research tool is better depends on your specific needs and preferences.
Merchant Words has been popular since its launch in 2012. It’s known for being reliable and comprehensive, covering a wide range of regions and providing extensive data.

On the other hand, Helium 10 is gaining popularity as a cheaper alternative with similar features and interface. While it may not have the global reach of Merchant Words, it still provides reliable data for the regions it covers.

My Tips: Helium 10 vs Merchant Words
If you only need to do product and keyword research and prefer a user-friendly tool with a visually appealing interface, then Merchant Words is a good choice.
It’s also suitable if your Amazon business operates in only one country and you want to explore more product options.
On the other hand, if you’re looking for a comprehensive set of tools beyond just product and keyword research and want competitive pricing, Helium 10 is a better option. It’s ideal if you prefer learning from industry leaders and want all your Amazon selling tools in one place.
