11+ Best Amazon Keyword Research Tools (Free and Paid) [2023]

Keyword research tools are the ultimate tool for Amazon sellers. Choosing – and including – the right keywords in an Amazon product description can make a huge difference in online sales. 

But it’s not enough to combine the most popular descriptors of the product and hope for the best. A bit of research is going to be necessary to find the most optimal keywords to include in an Amazon listing.

Luckily, ecommerce businesses can now see exactly what keywords consumers use, what keyword competitors are using, and what keywords lead to increased listing visibility and sales. 

How is all of this possible? Amazon keyword research tools.

What are they and how exactly does the technology work? Let’s take a look.

What is Amazon keyword research? Why is it important?

Keyword research helps you find which keywords are best to target. It provides valuable insight into the queries that your target audience is searching on Amazon, and what keywords lead to higher Amazon rankings. 

Just like searchers on Google, most Amazon users are only looking at the top search results for their query. Think to yourself: when have you ever gone to the second or even third Amazon results page?

Including the right keywords is essential to creating a listing that searchers will see. Sellers will need to include keywords in descriptions, product titles, product bullets, and even in alt text. 

The more optimized your post, the higher your ranking. And the higher your ranking, the more traffic your product will get, eventually resulting in greater sales and revenue. 

How do Amazon keyword research tools work? 

Amazon keyword research tools use AI and machine learning algorithms to provide a list of the most relevant keywords for your listing. They analyze Amazon’s algorithm that decides the order of sales results and then determines which keywords create the most effective product listings. 

Armed with that list, you can then integrate those keywords into your listings and then rank higher in Amazon search results.

Some keyword research tools (like Sellesta) make keyword research even easier by offering keyword suggestions for your current listings and providing AI content you can add with the click of a button. 

Using an Amazon keyword research tool will save you time and allow you to optimize your listing with the highest ranking keywords all with minimal effort on your part.
