One way to do this is by using a keyword research tool. They help you to profitable products that haven’t been saturated and can help you decide if a product is worth targeting or not.

In this review, we’re going to be covering the best keyword research tools on the market right now, their features, pricing, and everything in between so keep on reading!

2 Reasons To Use a Keyword Tool for Amazon FBA

Find Low Competition Keywords 

As the number of buyers using Amazon each month increases, so does the number of sellers. This means more competition which makes it harder to rank for profitable keywords. As a seller, you need to adapt and that’s where keyword tools come to help. 

Keyword tools have the ability to find you thousands of low competition keywords at the click of a button. You can perform keyword research manually but it would be too time-consuming. 

Keyword tools are able to tell you how many searches a keyword has, the difficulty of ranking for that item, and a bunch of other things. By not using one you allow your competitors to gain an advantage over you, which brings us to our second reason.

Analyze The Competition 

Most of the keyword tools available right now have features that allow you to perform competitor analysis. This is crucial if you want to succeed on Amazon. By taking a deeper look into your competition you’re able to instantly find products that are hot.

Keywords Everywhere is a browser extension for chrome or firefox. This means you can do your keyword research as you use Amazon’s website. For example, you load up Amazon and type in a keyword.

Keywords everywhere use a credit system instead of on a monthly basis. This acts like a pay-as-you-go service so you only have to buy the credits you need. There are three pricing plans :

1 credit = 1 keyword.

  • $10 = 100,000 credits.
  • $50 = 50,000 credits.
  • $100 = 1,000,000 credits.
