Top 10 Amazon Keyword Research Tools

What is Amazon Keyword Research Tool?

The Amazon keyword tool is a research tool that shows you the exact search terms ideal buyers use when searching for products on Amazon. It provides valuable insight from these search queries, so you can analyze and include them in your product listing to appear in the search results of customers. 

Amazon keyword research is a crucial practice you need to adopt to successfully sell on Amazon. By doing keyword research using Amazon keyword research tools, you gather valuable information to increase the visibility and ranking of your products and, overall, fine tune your Amazon marketing strategy.

Free Isn’t Always Free

What exactly do we mean by “free”? There are so many shades of free these days that it needs a little explanation. The software we’re looking for should be free forever, not just a free trial for 14 days before you have to pay.

Free plans will usually have limits, or come with ads or promotions for paid tools, but that’s OK as long as they provide genuinely useful features for free. After all, companies have to make money somehow or they won’t be around for very long.

Best Amazon Keyword Research Tools

The following are the best Amazon keyword research tools that we recommend to help you find the right keywords for your product listing. 

1. Keywords Everywhere

If you’re looking for an easy to use Amazon keyword research tool, the Keywords Everywhere tool is a simple and freemium browser add-on that reveals the search volume, cost-per-click, and competition data for every search term directly in your search bar. 

With competition data provided, you can look out for low-competition keywords to include in your product listing. 

This way, you increase the odds of your product listing ranking highly on the search result page.

The Keywords Everywhere tool is available for Chrome and Firefox browsers, is easy to install, and has an excellent reputation for providing accurate keyword suggestions. 

The tool has a 4.5 star rating from 1 million users using it across Amazon, YouTube, Google, Etsy, and eBay. 

The tool offers three payment plans, with the lowest plan starting at $21/year ($1.75/mo) which gives you 100,000 credits that last a year. 

A credit gives you search volume, CPC, competition, and 12 month trend data for one keyword. 

Pros of Keywords Everywhere

• Easy to use.
• Affordable.

2. Keyword Tool.io

KeywordTool.io is a free and user-friendly Amazon keyword research tool that uses Amazon Autocomplete to generate longtail keywords. The tool allows users to generate keywords for their products across Google, Amazon, Bing, YouTube, Pinterest, and many other platforms. 

Like Keywords Everywhere, this tool also provides an accurate readout of search volume, CPC, competition data, and search volume trends for a keyword to optimize your product listing. 

However, what sets Keywordtool.io apart is that it provides suggestions for negative (unwanted) keywords to exclude from the search results or your campaigns. 

For example, let’s say you sell men’s pants. You might want to add the term ‘kid’s’ to your negative keyword list so your product listing won’t appear to buyers searching for ‘kid’s pants’. 

Excluding negative keywords from your search results ensures that your listing does not appear in the search results of an irrelevant audience. 

Keywordtool.io allows you to filter out these negative keywords so you can add them to your listing. 

By doing this, your product listing only appears to a relevant audience that is more likely to convert.

Unfortunately, this tool does not offer a free version or free trial to access this feature. You can only access it with the paid version, KeywordTool Pro. 

Pros of KeywordTool.io

• You get keyword analysis across global amazon marketplaces 
• Ability to filter out negative keywords

Cons of KeywordTool.io

• Does not offer free plan or free trial

It is a free and beginner friendly Amazon keyword research tool, but it also has a paid version, if you want access to its services.
