If you’re tired of seeing the competition rank above your products on Amazon and losing sales to your rivals, it’s time to use a reliable keyword tool to inform your Amazon SEO efforts. The right tool can help you uncover keyword ideas, identify trends, and determine the competition. 

There are all kinds of Amazon keyword tools that can help you optimize your listings and gain better exposure. We’ve listed 10 keyword research tools that are worth trying out.


The 10 Best Amazon Keyword Tools in 2021:


What Is Keyword Research?

The Amazon A9 algorithm ranks products based on two factors: keywords and performance. It will look at keywords in your product titles, descriptions, bullet points, and backend keywords, which is why you need to place relevant keywords in these fields to rank better.

Another factor that determines product ranking is the performance of your product. The algorithm will look at your product’s performance history, conversion rate, click-through rate, and sales. If your products perform well, then they’ll rank better on Amazon. 

As Amazon becomes increasingly competitive each year, it’s more important than ever to invest time and effort into keyword research. This practice can help you find the relevant keywords to target, allowing you to optimize your Amazon listings and rank higher for valuable search queries. 

One of the simplest ways to conduct a keyword search is on Amazon itself. Just enter a keyword into the search bar and its auto-complete feature will suggest related search terms. It’s a quick and easy way to find long-tail keywords that are related to your product.

The problem is that it gives you no insights into the recommended keyword. Unfortunately, Amazon doesn’t offer keyword search volume data. It also won’t tell you what the competition is like for each keyword. That’s why you need third-party Amazon keyword tools.

Keyword research tools enable you to conduct more comprehensive keyword searches. You can look up high-volume keywords with low competition for organic and paid campaigns. 


 Tips for Optimizing Amazon Listings

Knowing how to optimize your Amazon listings can make a difference in your marketing and advertising efforts. Contrary to popular belief, Amazon listing optimization is not all about stuffing keywords into product titles and descriptions. 

Using the right practices, you can make your products more visible to potential buyers out there. Here are a few tips that you need to keep in mind.

  • Add high-volume keywords in your product title, description, and bullet points
  • Add your brand name to your product title
  • The keywords must be no more than 250 bytes (including spaces and punctuation)
  • Keyword stuffing isn’t necessary
  • Use separators like commas, dashes, and vertical bars to make titles more readable

What to Look for in a Keyword Research Tool

There’s a wide range of keyword research tools online with varying features and functionalities. Some offer extensive keyword generating capabilities for search engines like Google. Others, on the other hand, offer targeted data for e-commerce marketplaces like Amazon. 

Keyword difficulty score

High-volume search queries come with a lot of competition. If you have the right keyword tool, you can easily determine which keywords are worth ranking for. Some tools use keyword difficulty scores to tell you how hard it’ll be to rank for specific search terms.

Organic traffic research

Find an Amazon keyword tool that can generate both short and long-tail keywords. Depending on the tool you use, you can even uncover the keywords that the competition is using to boost your organic traffic. 

Paid traffic research

Aside from organic traffic research, Amazon keyword tools can help you monitor the keywords you’re using for paid campaigns. 

Competitor analysis

Another feature that you might want is competitor analysis. There are tools that can determine the keywords that the competitors are targeting. They can also inform you about the search queries that you aren’t ranking for.

If you want more powerful competitor analysis, you can look for tools that help you monitor their paid ad campaigns. These tools can identify the keywords that they are bidding on. 

Ease of use

Keyword research tools can be quite intimidating for new users, especially those with limited SEO expertise. Thus, if you aren’t familiar with keyword research, you should look for a tool with an intuitive interface and fuss-free dashboard. 

Affordability

There are free keyword tools for Amazon. However, many of them come with limited features and functionalities. You’ll have to subscribe to the paid plans to get the extensive keyword research capabilities. 

Thus, if you want to optimize your Amazon listings without spending hundreds of dollars, you need to carefully select a tool that can give you the best bang for your buck. The list we’ve prepared comes with a variety of options for entrepreneurs with different budgets.
