Amazon Keyword Research Using Helium 10 | Advanced Ranking Method

Last modified date

The Strategic Method Most Sellers Never Learn

Most beginners are doing Amazon keyword research and PPC completely backwards.

And if that sounds harsh, it’s probably because you were taught the wrong way.

What I see over and over again is sellers doing something like this:

  1. They open a keyword tool
  2. Download every keyword it spits out
  3. Dump them all into one PPC campaign
  4. Hope Amazon figures it out

That’s not a strategy.

That’s guessing.

And the results are always the same:

  • Ads spend money
  • Sales don’t follow
  • ACoS skyrockets

Not because Amazon PPC doesn’t work…

But because there’s no structure behind it.

In this guide, I’m going to show you how to properly do Amazon keyword research using Helium 10, and how to structure your keywords so your PPC campaigns actually work.


Why Most Sellers Fail at Keyword Research

Let me explain this with a simple example.

Imagine you’re running a food truck.

Day One

You open the window and sell food.

At the end of the day you know:

  • How much money you made

But you don’t know:

  • Which item sold best
  • Why people bought
  • What time sales spiked
  • Which promotion worked

You’re operating blind.

Day Two

Now you start tracking:

  • Which menu items sell best
  • What time people buy
  • Which promotion works
  • What items get ignored

Suddenly you’re not guessing anymore.

You’re learning.

That’s the difference between:

ApproachResult
Random PPCGuessing
Strategic PPCData-driven optimization

And keyword research is where this entire system begins.


Why You Need a Real Keyword Tool

Free keyword tools sound nice, but they have one major problem.

Bad data.

Bad data leads to bad decisions.

For serious Amazon sellers, I recommend using Helium 10’s Cerebro tool.

Cerebro recently merged with Helium 10’s Magnet tool, which means it now handles:

  • Reverse ASIN lookups
  • Keyword discovery
  • Keyword expansion

All in one place.


Step 1: Reverse Engineer Competitor Keywords

Instead of guessing what keywords might work…

Let Amazon tell you what already works.

This is called Reverse ASIN Keyword Research.


Find Your Top Competitors

Go to Amazon and search your main product keyword.

Example:

screw in tent stakes

Look at the top organic listings.

Do NOT choose:

  • Sponsored listings
  • Unrelated products
  • Different product types

You want the closest competitors possible.


Collect Their ASINs

Grab the top 3 organic ASINs.

You can find the ASIN:

  • In the URL (starts with B0)
  • On the product page

Example:

amazon.com/dp/B0XXXXXXX

Then paste them into Cerebro.

CompetitorASIN
Competitor #1B0XXXX
Competitor #2B0XXXX
Competitor #3B0XXXX

Click Get Keywords.


Step 2: Filter the Keyword Data

Cerebro may return thousands of keywords.

We need to narrow this down to high-quality search terms.

Use these filters.


Filter 1: Match Type

Set:

Organic

This removes paid keywords and focuses on organic rankings.

Result:

BeforeAfter
2600 keywords~800 keywords

Filter 2: Competitor Rank

Set:

Maximum rank = 60

This only shows keywords where competitors rank in the top 60 results.

These are the keywords actually driving traffic.


Filter 3: Number of Competitors

Set:

Minimum = 2

This means at least two competitors rank for the keyword.

This eliminates random or irrelevant keywords.


Final Keyword Set

After filtering you should have roughly:

Keyword CountQuality
200–300Highly relevant

This becomes your Master Keyword List.


Step 3: Clean Your Keyword List

Now you need to manually remove:

  • Brand names
  • Competitor names
  • Irrelevant keywords

Example of keywords to remove:

RemoveReason
Nike tent stakesBrand name
metal deck anchorsDifferent product
concrete boltsWrong use case

If you’re unsure about a keyword:

Hover over it in Helium 10 to preview results.

If the products shown aren’t your product, remove it.


Step 4: Create Your Master Keyword List

Once cleaned, save all keywords into a folder.

Name it:

Tent Stakes Master List

Helium 10 calls these folders Keyword Lists.

Make sure you add all pages of keywords.

This is the foundation for everything.


Step 5: Create Strategic Keyword Lists (The Most Important Step)

Now that we have our cleaned Master Keyword List, the next step is organizing those keywords into strategic groups.

This is where most sellers go wrong.

Most people simply export the keyword list and throw everything into a PPC campaign. But doing that destroys your ability to understand which keywords actually work.

Instead, we separate keywords into three distinct lists so each group can be tested independently in both listing optimization and PPC campaigns.

Keyword ListPurposeTraffic Type
Main KeywordsExact product searchesHighest buyer intent
Related KeywordsBroader or alternative searchesMedium buyer intent
Misspelled KeywordsTypo variations of keywordsLow competition traffic

By separating keywords this way, you can:

  • Track performance more accurately
  • Test PPC strategies independently
  • Optimize campaigns faster
  • Identify which keyword types actually convert

Now let’s walk through exactly how each list is created.


1. Creating the Main Keywords List

The Main Keywords list contains the most important keywords for your product.

These are the keywords that buyers type into Amazon when they already know exactly what they want.

In other words, these are high-intent purchase searches.

To create this list, go through your Master Keyword List and identify keywords that directly describe your product.

Ask yourself:

If someone searches this keyword, are they specifically trying to buy my product?

If the answer is yes, it belongs in the Main Keywords list.

For example, if you’re selling screw-in tent stakes, keywords that belong in this list might include:

Main Keyword Examples
screw in tent stakes
spiral tent stakes
heavy duty tent stakes
camping tent stakes
drill in tent stakes

These are the core keywords for the product.

They should appear in:

  • Your product title
  • Bullet points
  • Backend keywords
  • Exact match PPC campaigns

Once you identify these keywords:

  1. Select them in Helium 10
  2. Click Add to My List
  3. Create a new folder called something like:
Tent Stakes - Main Keywords
  1. Save the selected keywords to this list.

After saving them, delete those keywords from the master list view. This doesn’t remove them permanently — it simply makes the remaining keywords easier to review.


2. Creating the Related Keywords List

Next, we create the Related Keywords list.

These are keywords that are relevant to your product, but not necessarily the exact product name.

These searches typically come from buyers who:

  • Don’t know the exact name of the product
  • Are searching for something similar
  • Are using broader search terms

To identify these keywords, ask yourself:

Could someone searching this keyword still be looking for my product?

If the answer is possibly, it belongs in the Related Keywords list.

Continuing with the tent stake example, related keywords might include:

Related Keyword Examples
tent stakes
tent anchors
gazebo stakes
camping stakes
ground anchors for tents

Notice the difference here.

These keywords are less specific, but they still describe products in the same category.

These keywords are powerful because they can bring in new buyers who haven’t discovered your product yet.

Once you identify these keywords:

  1. Select them in Helium 10
  2. Click Add to My List
  3. Create a new folder called:
Tent Stakes - Related Keywords
  1. Save the keywords to this list

Then delete them from the remaining keyword list so the next step becomes easier.


3. Creating the Misspelled Keywords List

Now we move on to the Misspelled Keywords list.

This is an advanced step most sellers completely ignore, but it can be extremely effective for PPC.

Amazon shoppers frequently make spelling mistakes when typing searches.

Examples might include:

Misspelled Keyword Examples
tent staks
tent stakees
tent stkaes
screwin tent stakes
tent ankers

Even though these keywords are misspelled, Amazon’s search algorithm often still returns the correct products.

However, because many sellers never target these keywords, they typically have:

  • Lower competition
  • Lower cost-per-click
  • Cheap traffic opportunities

To build this list, scan through the remaining keywords in your master list and select any that are clearly misspellings of valid keywords.

Then:

  1. Select those keywords
  2. Click Add to My List
  3. Create a new folder named:
Tent Stakes - Misspelled Keywords
  1. Save them to the list.

Later in the process, we’ll actually expand this list even further using AI to generate additional typo variations.


Final Keyword Structure

By the end of this step, you should have three organized keyword lists created from your master keyword database.

Keyword ListDescription
Main KeywordsExact product searches with high buying intent
Related KeywordsBroader or alternative searches related to your product
Misspelled KeywordsTypo variations of product keywords

This structured keyword organization is the foundation of strategic PPC campaigns.

Instead of dumping thousands of keywords into a single campaign and hoping something works, you now have separate keyword strategies that can be tested, measured, and optimized independently.

And that is the difference between guessing with PPC and running it like a professional.


Step 6: Expand Keywords Using Cerebro Again

Next we take the best keyword from the main keyword list.

Example:

screw in tent stakes

Enter that keyword back into Cerebro.

Filter again:

  • Match Type → Organic
  • Aim for ~200 keywords

Now repeat the process:

  1. Remove irrelevant keywords
  2. Add to the proper keyword lists
  3. Delete duplicates

This step ensures you catch keywords competitors missed.


Step 7: Generate Misspelled Keywords (Advanced Trick)

This is an advanced step most sellers never do.

We’re going to generate high-intent misspellings.


Export Your Master List

Download your keyword list as a CSV.

Open it in Excel or Numbers.

Copy the entire column.


Use ChatGPT to Generate Typos

Go to ChatGPT and paste this prompt:

Give me a downloadable CSV file containing all the common Amazon search high intent typos for the following keyword phrases.

Paste your keyword list underneath.

ChatGPT will generate dozens of typo variations.

Example:

OriginalMisspelling
tent stakestent staks
tent anchorstent anchers
screw in tent stakesscrew in tent staks

Import Misspelled Keywords

Save the list as a CSV.

Then import it into Helium 10 under:

Keyword Lists → Misspelled Keywords

Now you have a massive list of low competition keywords.


Final Keyword Structure

After all this work, you should have four clean keyword lists.

Keyword ListPurpose
Master ListComplete keyword database
Main KeywordsHighest buying intent
Related KeywordsBroader search terms
Misspelled KeywordsLow competition traffic

Why This Strategy Works

Most sellers combine everything into one PPC campaign.

That destroys your data.

With this method you can:

  • Test strategies individually
  • Track performance per keyword group
  • Optimize campaigns faster

This is exactly like the food truck example earlier.

Instead of guessing, you’re learning.


What Happens Next?

Now that you have structured keyword lists, the next step is building strategic PPC campaigns.

Each keyword list becomes its own campaign.

Example structure:

CampaignKeyword ListMatch Type
Main KeywordsMain ListExact
Relevant KeywordsRelated ListExact
Master KeywordsMaster ListBroad
Misspelled KeywordsMisspelled ListBroad

This gives you clean data and allows you to scale profitable keywords quickly.


Final Thoughts

Keyword research is the foundation of every successful Amazon product launch.

When done properly:

  • Your PPC campaigns become predictable
  • Your listing ranks faster
  • Your ad spend becomes efficient
  • Your ACoS drops dramatically

And the biggest takeaway?

Don’t guess what buyers are searching for.

Let Amazon show you.

Reverse engineer your competitors, organize your keywords strategically, and build PPC campaigns that are designed to learn and improve.

That’s how professional Amazon sellers approach keyword research.

And once you understand this system, everything about Amazon advertising starts to make a lot more sense.
