Amazon keyword research is the process of identifying search terms (that are hyper-relevant to your product and highly searched for in Amazon’s search engine) so that you may optimize your product listing accordingly. The ultimate goal is to “rank” for these phrases at the top of Amazon’s search results.

Amazon keyword research is important because it enables your product listing to appear in the organic search results of Amazon’s search engine, which increases your product visibility and opportunities to convert potential customers into actual customers.

After you’ve identified the keywords you’d like to rank in Amazon’s search results for, you’ll need to work those into the various parts of the product description (Title, Bullet Points, Description, Search Terms, etc.). You can use a tool like Listing Builder to optimize your product listing with your target keywords.

A “keyword ranking” is the placement of your product listing in Amazon’s search engine based on a specific search term someone types into Amazon. If your keyword ranking is #1, your product is at the very top of Amazon’s search results when someone searches that keyword. If it’s #2, you’re directly after the top result.
Amazon keyword rankings are determined by a number of factors, such as: the number and quality of reviews, the optimization level of the product listing, the number of sales a product listing has generated, etc.

By utilizing a third-party solution like Helium 10’s Cerebro or Magnet, sellers are able to easily find Amazon keyword search volume with some of the most accurate data on the market. By inputting a keyword or existing Amazon ASIN, Magnet and Cerebro return thousands of related keywords with several helpful metrics for each one, including estimated Amazon keyword search volume.

Third-party solutions like Helium 10’s Magnet allow sellers to easily view Amazon keyword search trends. This includes 30-day search volume changes, estimated search volume dating back multiple years, and average competing products. Sellers can use these Amazon keyword search trends to make important decisions when it comes to including keywords in their product listings.

In order to rank for keywords on Amazon, you must optimize your product listing with highly relevant keywords, and position your listing to succeed in other ways (i.e. increase the number of positive reviews, include Enhanced Brand Content, etc.). When researching how to rank for keywords on Amazon, you will often find the best keywords are those that are hyper-relevant to your product listing, high in search volume, and low in competition. Once collected, you want to naturally include these keywords throughout your product listing to help the Amazon algorithms rank your product based on its keyword relevance.

Amazon doesn’t limit the number of keywords allowed; it limits the number of characters. You can currently include up to 250 characters of keywords in your Amazon product listing “Search Terms” area. While there is no firm Amazon search terms limit, you do want to be wary of “keyword stuffing.” Sellers should not be blindly adding as many keywords as possible to their listings. Instead, focus on utilizing keywords naturally (when relevant) and not compromising readability to do so.

By using Helium 10’s Amazon competitor analysis tool, Cerebro, you can easily identify keywords that competitor products are ranking for. Simply plug in an ASIN (up to 10) and instantly see competitors’ keywords on Amazon using a variety of filters, sorting options, metrics, and sales graphs. Pay attention to which keywords are working for your competition, as well as the keywords that aren’t working; both sides of the coin are important considerations as you optimize your listing.

Helium 10’s Index Checker allows you to see if your product listing is indexed for a given keyword within 30 seconds. You can do this in bulk, rather than spending multiple hours checking each keyword.
To do this manually, you must visit Amazon, set the search filter to “All Categories,” and search for a listing using its ASIN (Amazon Standard Identification Number).

The best Chrome Extension for finding Amazon keywords is one that works quickly and accurately to deliver estimated search volume, sales history, and review insights, all with the click of a button. When using Helium 10’s Chrome Extension, you can easily visit an existing product page, click on “Keywords,” and automatically pull up Cerebro for that specific product’s ASIN. Once in Cerebro, you can view all of the keywords that the product currently ranks for.

Helium 10’s Magnet and Cerebro are two of the best Amazon keyword research tools on the market. Magnet enables you to conduct exploratory keyword research with a number of filters (Search Volume, # of Competing Products, Title Density) and data points (Keyword Sales, Magnet IQ Score, Search Volume, Search Volume Trend, etc.) to identify viable opportunities. Cerebro enables you to conduct a competitive analysis of your competitors’ keyword targets so you can reverse engineer their work.

How to Choose Amazon Keywords

The best way to find keywords on Amazon is to use a third-party tool like Helium 10 to:

  • See what your top competitors’ product listings are ranking for (with Cerebro)
  • Expand keyword combinations (with Magnet)

When researching how to find viable keywords on Amazon, you will quickly discover the best way to do so is through the use of an Amazon keyword research tool. These tools allow users to access data, previously inaccessible through the public Amazon marketplace.

Estimated search volume, competitor rank, and custom metrics (like a dedicated demand/competition ratio) make third-party Amazon keyword research tools a must-have for anyone looking to start their online business. Without keyword research tools, sellers would be left to their own devices to manually enter search queries on Amazon and browse a limited selection of “related” or “frequently searched” phrases.

Step 1

To start off, it’s important to understand that for most listings, the majority of sales come from the top 5 to 15 keywords. The easiest way to find these keywords is to perform an audit of your top competitors.

First, decide what related keyword you think is the main keyword for your product. We’ll call this a “seed keyword”.

Run Xray (a keyword tool part of the Helium 10 Chrome Extension) to see the estimated sales of the top products indexed for that seed keyword. Pay attention to the top three or four only. These are the dominating products.

Step 2

Copy the product identifier numbers (aka ASINs) of those top three to four products and paste them into Cerebro, Helium 10’s Amazon keyword research tool. A keyword list will be generated in seconds!

Step 3

When you want to know how to find all the different combinations of a keyword (aka, phrases) that exist on Amazon, Magnet, Helium 10’s other keyword tool, can help with that. Using smart filters and studying results for non-English keywords that are being searched for on Amazon! These keywords are mostly ignored by most sellers, which is good news for you. By including them in the backend of your product listing, you instantly get an edge on your competition!

Using Helium 10’s Amazon keyword research tools, you unlock the ability to uncover opportunities hidden from your competition. Interested in testing them out for yourself? Sign up for a free Helium 10 account here!

The Best Amazon Keyword Research Tools

Keywords are phrases that people actively type into Amazon’s search engine to find a product they’re looking for. If you’re unable to identify keywords that are hyper-relevant to your product with a high level of monthly searches and low competition, it’s going to be nearly impossible to generate organic sales through Amazon.

Keywords are the basis of a good product listing, and influence how you sculpt the page so that it ranks well within Amazon. Not ready to get in-depth with one of the above tools?
