This keyword suggestion tool offers a professional level of service to all sellers who want to improve the performance of their products on Amazon. Kparser provides better service than its competitors to Amazon sellers for two main reasons. The first feature that differentiates Kparser from other Amazon keyword tools is the quality of gathered results because it utilizes advanced filters. The second feature is the speed of the process, which enables its users to sort and group the results with a few simple clicks. It does, however, lack the power of more advanced keyword tools such as AmaSuite or Helium 10.
3. MerchantWords MerchantWords keyword tool
Ranking: 3/10
With more than 170 million keywords in the database, MerchantWords is one of the leading keyword tools currently available to entrepreneurs who want to increase the sales of their products on Amazon.

4. KeywordInspector KeywordInspector keyword tool
Ranking: 4/10
This online platform offers a number of possibilities to its members, including the Trending Keyword Search option. This feature enables members to check the top new keywords on a daily or weekly basis. Indexation Tester and Reverse ASIN features guarantee that your Amazon products will always be perfectly optimized to reach the highest amount of buyers.

5. Keyword Tool Keyword-Tool keyword tool
Ranking: 5/10
Visitors of this easy to use keyword search tool can effortlessly switch between Google, AppStore or Amazon tabs to quickly get the best keywords for their products.

6. Keyword Tool Dominator keywordtooldominator
Ranking: 6/10
The fact that more than 15,000 owners actively use Keyword Tool Dominator shows just how powerful this keyword tool is. Users can choose between Google, Amazon or YouTube keyword tools among many others depending on their needs. The Autocomplete database offers keyword information made by real users, which makes this app a perfect choice for all sellers who rely on accurate information. Even though creating a Keyword Tool Dominator account is free, paid access is now sold as a one-time lifetime plan starting at $29 (rather than the old $49.99 package), and the app still lacks the power of some more advanced Amazon keyword tool software.
7. Google Keyword Planner Google Keyword Planner
Ranking: 7/10
Google AdWords is a powerful advertising tool, which can provide you with the data necessary to boost sales of your Amazon products. The Google Keyword Planner is just one of the many free features offered by Google AdWords.

8. Sonar Sonar keyword tool
Ranking: 8/10
Sonar will provide you with keyword suggestions based on search queries made by real Amazon users. A simple search for the best keywords for Amazon products through Sonar will provide sellers with the keywords they need to include in their campaigns.

One important caveat for 2026: Sonar (originally a Sellics feature, now owned by Perpetua) has been flagged as a legacy tool slated for discontinuation, so don’t build your workflow around it long-term.
9. Scientific Seller Scientific-Seller keyword tool
Ranking: 9/10
This free and easy to use online platform isn’t like other Amazon keyword tools because its focus isn’t on speed. Instead, Scientific Seller is more concerned with the relevance and quality of the data it provides. For this reason, keyword searches may take all night while Free Amazon Keyword Tool searches further and further from the seed word. Scientific Seller only provides keyword options for Amazon, but its users must be patient since they can’t rely on its ability to deliver the data fast.
10. Ahrefs Site Explorer Ahrefs Site Explorer
