In the world of Amazon selling, keyword research is one of the most critical aspects of driving traffic to your product listings. Keywords help your products get discovered by potential customers, leading to higher sales and, ultimately, business growth. However, finding the right keywords that will convert into sales can be challenging.

This article will explore the best tools and techniques Amazon sellers can use to discover high-converting keywords and optimise their listings.

Why Keyword Research is Crucial for Amazon Sellers

Amazon is one of the largest online marketplaces, with millions of products available for customers to browse. With such a vast inventory, standing out can be difficult. Keywords play a vital role in ensuring that your products appear in relevant search results. By targeting the right keywords, you can:

  • Increase visibility: Proper keyword usage helps your products rank higher in Amazon’s search results, increasing the likelihood that potential customers will find your listings.
  • Boost sales: High-ranking products attract more clicks and conversions, leading to higher sales and better performance metrics.
  • Enhance product relevance: Keywords that accurately reflect your product’s features and benefits ensure that you attract the right audience, reducing bounce rates and returns.

Techniques for Effective Keyword Research

Even with the best tools at your disposal, applying the right techniques is essential for uncovering the most valuable keywords. Here are some strategies to help you find high-converting keywords for your Amazon listings:

Start with Seed Keywords

Begin your research by identifying seed keywords—basic terms that describe your product. These are usually short, generic terms such as “wireless headphones” or “coffee mug.” Use these seed keywords in your keyword research tools to generate a broader list of related keywords.

Analyse Competitor Keywords

Competitor analysis is a crucial step in keyword research. By examining the keywords that top competitors are ranking for, you can discover profitable keywords that you may have overlooked. Tools like Helium 10’s Cerebro or Jungle Scout’s Reverse ASIN Lookup can help you identify these competitor keywords.

Leverage Long-Tail Keywords

Long-tail keywords are longer, more specific phrases that usually have lower search volumes but higher conversion rates. For example, instead of just targeting “yoga mat,” consider targeting “non-slip eco-friendly yoga mat.” These keywords tend to have less competition, making it easier to rank higher and attract more targeted traffic.

Prioritise Keywords by Search Volume and Relevance

While it’s tempting to go after high-search-volume keywords, it’s crucial to balance search volume with relevance. High-volume keywords are often highly competitive, making it harder to rank. Instead, focus on keywords that are highly relevant to your product and have a reasonable search volume.

Optimise for Amazon’s A9 Algorithm

Amazon’s A9 algorithm determines how products are ranked in search results. To optimise for A9, ensure that your chosen keywords are naturally incorporated into your product title, bullet points, description, and backend search terms. A well-optimised listing that aligns with A9 will increase your chances of ranking higher.


Effective keyword research is the backbone of a successful Amazon selling strategy. By utilising the right tools and techniques, you can identify high-converting keywords that not only improve your product’s visibility but also drive more sales. Whether you’re just starting or looking to refine your keyword strategy, the tools and methods discussed in this article will help you stay ahead in the competitive Amazon marketplace.
