Do you know that about 70% of Amazon customers do not go past the first page of search results? This basically means that if your product is not among the top results, you lose sales every day. And here is the good news: Using a Free Amazon keyword tool can help you solve this problem, and you will not even have to spend a cent.
What Is a Free Amazon Keyword Tool and Why Is It Useful?
In order to know what words and phrases customers use when they search for products on Amazon, a Free Amazon Keyword Tool can be very helpful for you. After that, you include these words in your product’s title and other product content to be able to rank higher and get more exposure.
Here is why this is important: The algorithm of Amazon’s search engine (called A10) ranks products based on keyword relevance, conversion rate, sales performance, and seller authority. So, if your product listing is not in line with what customers are searching for, your product will not be shown by Amazon – even if it is very good.
Frontend Keywords vs Backend Keywords
It is very important to know the difference between the two types of Amazon keywords before we select a tool.
Frontend keywords are those that are directly visible to the shoppers in your product listings – title, bullet points, and product description.
Backend keywords refer to those that are tucked away inside your Seller Central account under the “Search Terms” tab. Shoppers never see them, but the algorithm of Amazon reads them and uses them for matching your product with the right searches. Amazon allows you to fill up to 250 bytes (around 40 keywords) for backend fields.
They complement each other to maximize the extent of your product reach.
Which Free Amazon Keyword Tools Are Actually Worth Using?
There are several strong free options available right now.
| Tool | Free Features | Best For |
| Helium 10 (Magnet) | Limited keyword search, search volume trends | FBA sellers, PPC campaigns |
| Keyword Tool (keywordtool.io) | 750+ long-tail suggestions per search | Listing optimization, content |
| Keyword Tool Dominator | 2 free searches per day, popularity scores | KDP, FBA, niche research |
| SellerApp | Core keyword data from Amazon autocomplete | Beginner and intermediate sellers |
| Ahrefs Amazon Tool | Keyword ideas from 100M+ database | Advanced sellers, Google crossover |
| KeySearch | Amazon + Google data combined | Budget-conscious sellers |
| Keyword.io | Data from 11+ platforms including Amazon | Multi-platform sellers |
Each tool pulls data differently. Some use Amazon’s autocomplete feature. Others analyze clickstream data from real shoppers, which tends to be more accurate.
How Do These Tools Find Keywords?
Most free Amazon keyword tools only have two methods for obtaining keywords.
The first way is by scraping the autocomplete feature from Amazon. You enter the seed keyword – a broad term like “yoga mat” – and the tool adds letters or numbers to it (“yoga mat a,” “yoga mat b,” and so forth). It then gathers all of the suggestions that Amazon gives back. So, you get a pretty long list of real, buyer-generated phrases.
The second way is to analyze clickstream data. Tools such as Ahrefs figure out what people searching on Amazon really type and click, which is more precise but commonly only available in a paid plan.
How to Find the Right Keywords?
Not every keyword is a priority for you. When you perform an analysis of your keyword inventory, be sure to consider:
- High search volume — the more folks that search, the more potential buyers there are
- High conversion rate — some keywords find browsers, some find buyers.
- Low competition — when there are fewer challenger products, there is a higher chance to rank
- Relevance — the keyword must correctly and truthfully describe the product
If you’ve got a keyword that’s highly searched but not very relevant, it will damage your listing. One way through which an algorithm signals a bad product quality is that Amazon penalizes irrelevant keyword stuffing by lowering your conversion rate.
How Do You Use a Free Keyword Tool Step by Step?
It’s not complicated to use a free Amazon keyword tool. This is the way:
- Choose your tool (Helium 10, SellerApp, or Keyword Tool Dominator are excellent choices for beginners)
- Type in your seed keyword – a brief, general phrase that characterizes your product
- Go through the list of possible keywords generated.
- Sort the list by search volume and keyword relevance.
- Select the best keywords and place them in your product title, bullet points, and description.
- Put the rest of the keywords into your backend “Search Terms” field at Seller Central.
Here’s a clever hint: check out the listings of your competitors for ideas. Find the highest-ranking items for your main keyword, see their titles and bullet points, and notice the phrases they keep using. Those are probably good keywords that you should also be aiming at.
Is it possible to conduct Amazon keyword research by utilizing Google tools?
Yes, you can actually use Google’s tools for Amazon keyword research, and they might even turn out to be more effective than expected by most sellers. Google’s autocomplete function displays the most frequently searched terms, which usually correspond to what Amazon customers enter. Also, Google’s related searches found at the bottom of the result pages are another source of keyword ideas.
On the other hand, tools such as Ahrefs provide more features. By entering a competitor’s Amazon product URL into Ahrefs Site Explorer, you can discover the Google keywords that bring organic visitors to that product. Integrating those keywords in your product description will increase your odds of ranking in both Amazon and Google searches simultaneously.
What exactly are long-tail keywords? Why should you consider using them?
Long-tail keywords are longer, more descriptive phrases that target a very specific theme, like “waterproof hiking boots for women size 8,” compared to “hiking boots” only.
There are three primary reasons why they are important:
- There is much less competition for long-tail keywords than for short, general ones.
- They attract customers who are aware of exactly what they want (higher likelihood of purchase)
- They are simpler to rank for when you are a new or smaller seller.
For instance, tools such as Keyword Tool can provide over 750 long-tail keyword variations from one seed keyword for free. Incorporating these keywords into your product pages could result in steady, high-converting traffic even if you don’t use paid advertisements.
Are Backend Keywords Still Important in 2026?
Yes, of course. Also, Backend keywords are still very much alive, which is why they count as strong factors for Amazon SEO even though they get overlooked. Many sellers concentrate solely on the product title and neglect the backend fields completely – which is a big mistake.
Listed below are the guidelines for backend keywords:
- Stay within the limit of 250 bytes.
- Do not duplicate any keywords that you have already included in your title or bullet points (Amazon indexes those)
- Exclude stop words like “and,” “a,” “of,” and “with.”
- Stay away from punctuation or special characters.
- Write words in natural order as a shopper would type
For instance, “white coffee mug insulated” is the correct form, not “insulated white mug coffee.” Act as a buyer rather than a seller.
How Often Should You Update Your Keywords?
Keyword research should not be something you do once and forget. Search behaviors are always changing. A viral product can lead to the sudden increase of related keywords even overnight. Similarly, how a holiday, back-to-school, or summer sales event can change not only what shoppers are seeking but also how dramatically.
One well-known tip is to perform keyword analyses and check for upcoming trends every single month at least. In addition, use Amazon Brand Analytics to keep a close eye on your listing’s performance, and if you are a member of Brand Registry. You can see which search terms led to clicks, purchases, and even demographic behavior. By analyzing this data on an ongoing basis, sellers outperform those who set and forget their keywords.
Smart Ways to Get More From Your Free Keyword Tool
You don’t have to have a paid subscription to conduct comprehensive keyword studies. Here are some tips that work well with free tools:
- Extract keywords from your product reviews. Check out what customers are saying about your product using their own words. This is the natural language that prospective buyers will use while searching on Amazon.
- Study competitor listings manually. Look at the top 5 products that appear in the results for your main keyword. Identify common phrases that are repeated in their titles and bullet points.
- Use the search bar on Amazon directly. Start typing your seed keyword and document every suggestion that appears in the dropdown list. Also, try it by using different starting letters.
- Follow up on what your PPC ads reveal. If you are running Amazon advertisements, then the Search Term Report within Seller Central shows the exact phrases that triggered your ads and led to sales. These keywords should be added to your organic listing.
