Selling on Amazon without the proper tools is almost impossible. It’s like trying to light a fire without a match, or row a boat without a paddle, or play golf without a golf club, or… you get the point.

Amazon is a complex marketplace and selling relies more on analytics than it does on intuition. Are free selling tools the answer? If you are completely new to Amazon, free tools are a good place to start.

Once you become more familiar with the marketplace though, you will need paid seller tools to access more accurate data, supporting content and resources, and to save you time and money. So, if you are going to use free seller tools to get a feel for the marketplace, in this guide, we will discuss seven free Amazon sellers tools that have become popular in 2021. 

Ready to go? Let’s get started!


Tool #1: Unicorn Smasher – Product Hunting Tool

This colorful looking Amazon FBA toolkit lets users determine product/niche viability. 

Unicorn Smasher – free Amazon product research tool

Unicorn Smasher was the go-to free tool until October 2020 when they released a paid Pro version. To use the tool, you will need to download the free chrome extension, visit Amazon.com and search for a keyword. Once the listings appear, click on the Unicorn Smasher icon on the top-right corner of your Chrome browser.

After this, a table should appear with a list of competitors. You will also get some useful information like product price, category, rank, estimated sales, estimated revenue and more. While this is all great information, be weary of its accuracy.

After the paid Pro version went live, developers halted support for the free chrome extension. Without the routine updates, tool functionality suffered and data accuracy took a nosedive. As for the $49 Pro chrome extension-- there are more accurate, powerful, and holistic FBA toolkits available in the market.

The Verdict: Even if the tool is free, sellers need relatively accurate data to make important business decisions. If you’re not ready to spent money on a subscription right now, we recommend checking out other free keyword research tools like Keywords on Fire Lite (tool #7 on our list) to determine product viability.


Tool #2: Camelcamelcamel – Price Tracking Tool for FBA Sellers

Another popular and oddly-named tool on our list is CamelCamelCamel. Unlike Unicorn Smasher, CamelCamelCamel offers browser functionality for Microsoft Edge, Mozilla Firefox, Apple Safari, Opera, and obviously, Google Chrome. 

CamelCamelCamel – free Amazon price tracking software

The founders describe the tool as a price tracker capable of monitoring millions of products and enhancing decision-making by alerting sellers to price changes. Like most repricers, CamelCamelCamel offers functionality in the North American and the major European markets like UK, Germany, Spain, Italy, and France.

Other features include:

  • Price History Charts: Allows sellers to view price variations for multiple ASINs over time as well as high, low, and average prices for specific keywords. Item availability and price are constantly updated; however, according to data found on CamelCamelCamel’s official page, “prices should always be checked on Amazon” which indicates that the updates may not be as immediate or accurate as they claim.
  • Email Alerts: Makes tracking easier. Emails are sent out to users whenever a competitor’s price exceeds or falls below a set threshold. 
  • Price Watch Management Interface: Let’s users view tracked products in table format. Here, tracked products are displayed with additional information including a picture, a small description, the price at which it was tracked, the current price, and the desired price. 

CamelCamelCamel is a decent Amazon price tracking software that should be used more to understand how repricers work rather than relying on it for personal and practical use. The problem with CamelCamelCamel—as with most Amazon freeware—is inaccurate data that cannot be relied upon when running businesses worth thousands of dollars. 

The Verdict: Feel free to tinker around with it a bit to understand how price changes and tracking works for product listings on Amazon.

Tool #3: Keepa - Price Tracking & History

Keepa and CamelCamelCamel are similar insofar as tracking product and competitors’ price updates are concerned. 

Keepa – free Amazon price tracker

Keepa was completely free to use up until 2019 when it introduced paid packages. Sellers can still use features like Access Finder, Seller Storefront, and Category tree--albeit with limited functionality--but access to premium features now sets users back €19 per month. Some of these premium features include:

  • Ability to view historic and current stock of offers
  • Interactive Buy Box, sales rank, and rating & review count graphs
  • Price increase alerts
  • Access to the Keepa API (application programming interface)

Even with a powerful marketing engine behind it, it’s hard to justify the price tag considering that by adding a few more euros you'd be able to purchase a paid subscription to a multi-functional seller toolkit.

When compared with CamelCamelCamel, Keepa isn’t able to delve too far into the past to provide historical data and in that regard, is inferior to its counterpart.

The Verdict: The same as with CamelCamelCamel—use it to see how price tracking works and then move onto bigger and better software. 


Tool #4: Scientific Seller – Keyword Research Tool

Continuing our list of free Amazon seller tools let’s get to number four: Scientific Seller. What stands out the most about Scientific Seller is that it advertises itself as “The World’s Slowest Keyword Tool”. That’s a great marketing hook; of course, it isn’t really the world’s slowest keyword tool. 

Scientific Seller – the self-proclaimed world’s slowest keyword tool

Once users run a keyword search, it presents them with a list of relevant keywords but the search doesn’t stop there. It keeps searching deeper to pull to relevant yet less-targeted keywords that sellers can use to drive in an extra bit of traffic.

After entering a keyword and hitting the “Start My Keyword Search” button, the results are bifurcated into Amazon Buyer Keywords and Stuff Keywords. Stuff Keywords refer to the main search term plus related keywords. There’s an additional column just left of Stuff Keywords indicating the number of available keyword suggestions.

All of this appears to be fancy stuff, but the major downside is that these results are estimates and cannot be taken at face value. 

The tool then goes on to suggest that the data provided should be used to run PPC campaigns which may not be the best idea. Promoting ASINs via ad campaigns requires a good chunk of money and research using accurate and reliable product research tools. Unfortunately, a free tool like Scientific Seller just doesn’t fit the bill. 

The “Seller” and “Power Seller” plans range from $29.99 to $49.99 are enticing, with the added benefits of unlimited searches and global marketplace functionality. However, they do fall prey to the same problem: inaccurate keyword research data. 

The Verdict: For just a few more bucks you could have a powerful seller toolkit with more accurate keyword research, to name a few tools, at your fingertips.

Tool #5: Keyword Tool

As the name indicates, Keyword Tool has one job: researching keywords across high-volume websites like YouTube, Google, Instagram, Twitter, Bing, eBay, and most importantly, Amazon. Nothing flashy—just a good ol’ SEO tool with the sole purpose of researching and presenting keywords.

Keyword Tool

There’s nothing wrong with the tool per se, the only point of critique that we—and many sellers—have with Keyword Tool is that it’s a multi-platform software that lacks core FBA-selling features. Sure, it can generate a large number of long-tail keywords based on Amazon’s autocomplete feature but given how far Amazon seller tools have come, that’s the very least anyone would expect from software featuring keyword research capabilities.

Keyword Tool is rudimentary at best—and then there’s the elephant in the room: $69 for the Pro Basic subscription plan which, FYI, doesn’t even feature Cost-Per-Click data.

The Verdict: We suggest exploring other options.

Tool #6: Google Trends

Google Trends was not created specifically for Amazon sellers. It was created to enable users to find out the search volume for a specific keyword in relation to all searches over a certain period of time. 

Google Trends – free keyword research tool

The tool is handy for two main reasons:

  1. Accurate keyword search volume results
  2. Determining product seasonality and predicting future trends

Another cool feature is the ability to carry out comparative keyword research based on time and region. This allows sellers to uncover products that have a high chance of selling well in local markets. Historical trends are also great for anticipating rising demand for certain products and capitalizing on opportunities. 

Google Trends is most effective when used alongside other software designed specifically for Amazon sellers.

The Verdict: This one isn’t bad! Google Trends can be quite handy if you’re searching for a seasonal product to sell on Amazon. 


Tool #7: Guru Tools

Guru Tools are quite easily the best free tools available to new sellers right now. They focus on optimizing product listings. These tools include:

  • Keywords on Fire Lite: This tool is able to give you accurate and up-to-date monthly search volume data for any keyword because of a partnership with Amazon. It also lets users see which competitor is bringing in the most traffic. Equipped with this, users can optimize product listings to ultimately drive traffic and boost conversion rates.
  • ASIN Index Checker: Manually checking to see whether your product is listed for all relevant keywords can be a real pain. With the ASIN Index Checker tool, you can unearth keywords you haven’t included in the product listing to increase overall visibility!
  • FBA Calculator: Most of us already know about the countless types of fees involved. Without having a clear idea of selling costs, it’s easy to invest in the wrong product or make bad business decisions. The FBA Calculator tool dispels all doubts by letting sellers know what types of fees to expect. 

These three constitute the perfect free Amazon seller tools trio available to newcomers—and it only gets better. ZonGuru also offers a 7-day free trial for their seller toolkit. This includes 16 powerful features catering to every aspect of FBA selling.

The Verdict: Free tools don’t get better than this--knock yourself out!
