Amazon Keyword Search Volume: How to Use It for SEO Too

You're selling on Amazon and someone tells you to "do keyword research." You pull up a tool, find search volume numbers, and then freeze — because you're not sure if the 18,000 monthly searches for "stainless steel water bottle" means anything useful, or whether those are Amazon shoppers, Google searchers, or some blended guess that covers neither well.

That confusion is worth untangling, because Amazon keyword search volume and Google keyword search volume measure different things — and if you're running a product site, an e-commerce store, or even a brand that sells both on Amazon and through your own site, understanding the difference is what separates wasted content from content that actually earns traffic.

What Amazon Keyword Search Volume Actually Measures

When a tool reports Amazon keyword search volume, it's estimating how many times shoppers typed that phrase into Amazon's own search bar in a given month. Amazon does not publish this data directly. Every number you see — whether from Helium 10, Jungle Scout, or MerchantWords — is a reverse-engineered estimate based on product rankings, sales velocity, and algorithmic modeling.

The intent behind those searches is highly transactional. Someone typing "silicone baking mat set" into Amazon is almost certainly ready to buy. That's different from someone Googling the same phrase, who might be comparing brands, reading reviews, or writing a recipe blog.

This matters because a keyword with 40,000 monthly searches on Amazon and 2,000 monthly searches on Google isn't the same opportunity twice — it's two different audiences at different stages of a buying decision.

Why This Gap Is Useful for Your Website

Here's where most product-focused businesses leave traffic on the table: they do Amazon keyword research to optimize their listings, then ignore what those same keywords could do for their website's organic search presence.

Amazon converts quickly. Google builds compounding traffic over time. Both matter.

If you have a brand site — even a basic one — ranking for the Google-side of those same product keywords puts you in front of buyers before they reach Amazon. You capture the research phase. You build email lists. You control the customer relationship.

The keyword research you've already done for Amazon is a starting point for that Google strategy, not a separate project.

How to Cross-Reference Amazon and Google Search Volume

The workflow is simpler than it sounds:

Step 1: Export your Amazon keyword list. Whatever tool you use — Helium 10, Jungle Scout, DataDive — export the keywords you're already targeting or ranking for on Amazon.

Step 2: Run them through a Google keyword tool. Google Keyword Planner (free, requires a Google Ads account), Ahrefs, Semrush, or even browser extensions like Keywords Everywhere will give you Google-side search volume for those same phrases.

Step 3: Sort by opportunity. Look for keywords where:

• Google search volume is meaningful (even 200–1,000/month is worth targeting for a niche product)
• The search intent on Google is informational or commercial — meaning a blog post, guide, or comparison page could rank
• Your competitors don't have strong content targeting that phrase

Step 4: Build the content. This is where most product businesses stop and most content businesses start. The sweet spot is doing both.

For a deeper look at how volume data should actually drive decisions, keyword search volume explained breaks down what the numbers mean and when to trust them.

The Intent Mismatch Problem

Not every high-volume Amazon keyword translates to a Google content opportunity. "Buy silicone baking mat" is a transactional search on both platforms — a Google user searching that is ready to buy, not read. A product page or PPC ad serves them better than a guide.

But "silicone baking mat vs parchment paper" — that's a comparison search. A guide, a YouTube video, a blog post. That phrase may have lower Amazon search volume (or none at all, since Amazon users rarely search comparisons), but it has real Google traffic from buyers doing research before they commit.

This is the strategic gap: Amazon volume tells you what's selling. Google volume, broken down by intent, tells you where the conversation happens before the purchase.

What to Do With Low-Volume Keywords on Google

210 searches per month sounds small. For a national brand chasing mass-market keywords, it is. For a niche product site, 210 highly targeted searches per month from buyers who are exactly your customer is often worth more than 10,000 vague ones.

The calculation isn't volume alone — it's volume multiplied by intent multiplied by your ability to rank. A keyword with difficulty 13/100 and 210 monthly searches that you can rank for on page one in 60 days beats a keyword with 50,000 searches and difficulty 78 that you'll never crack.

That's why understanding what search volume means for SEO is a prerequisite to using any of these numbers well. Volume is one variable. It doesn't stand alone.

How to Track Whether It's Working

Once you publish content targeting these keywords, you need to know if it's ranking. Google Search Console shows you what queries triggered impressions, but it lags and doesn't show competitor movement. A proper keyword reporting setup lets you track position over time for the exact phrases you targeted — so you know if a piece climbed from position 22 to position 8 and is worth updating to push it onto page one.

Without tracking, you're publishing into a void. With it, you can see which pages are almost ranking and give them a push.

Where to Find Amazon Keyword Search Volume Data

The most-used tools:

• Helium 10 — Chrome extension and full platform, gives search volume estimates directly from Amazon data modeling. Broad plan starts around $39/month.
• Jungle Scout — Similar functionality, slightly different estimation methodology. Good for cross-referencing.
• MerchantWords — Older but still useful, focuses exclusively on Amazon search data.
• DataDive — More advanced, better for listing optimization workflows.

For the Google side, Keywords Everywhere alternatives covers what your options are if you want browser-level data without committing to a full SEO suite.

None of these tools tell you what content to build for your website. That's a separate analysis — comparing what your competitors' sites rank for versus what yours doesn't — which is where a service like Rankfill can map those gaps systematically if you'd rather not do it manually across multiple tools.

The Practical Summary

Amazon keyword search volume tells you what shoppers search on Amazon. Google keyword search volume tells you what people search on Google. They overlap, but they're not the same audience or the same intent.

If you're selling products, the research you've done for Amazon is a free head start on Google SEO — not a duplicate effort. Export your Amazon keywords, check Google volume and intent for each, build content that intercepts the research phase, and track what ranks.

The businesses doing this aren't doing something exotic. They're just not stopping at the Amazon listing.

FAQ

Is Amazon keyword search volume the same as Google search volume? No. Amazon volume measures searches on Amazon's platform. Google volume measures searches on Google. The same phrase can have very different numbers on each, and the intent behind the search often differs too.

Can I use Amazon keyword data for my website SEO? Yes, as a starting point. Export your Amazon keywords and run them through a Google keyword tool to see which ones have search volume and informational intent on Google — those are candidates for content pages on your site.

Are Amazon keyword search volume numbers accurate? They're estimates. Amazon doesn't publish this data publicly, so tools like Helium 10 and Jungle Scout reverse-engineer it from product rankings and sales data. The relative ranking of keywords (this one is searched more than that one) tends to be reliable. Exact monthly numbers should be treated as directional.

What's a good search volume to target for a niche product keyword? There's no universal threshold. 200–500 monthly searches for a targeted, low-difficulty keyword in a niche product category can be very worth pursuing — especially if those searchers are buyers. Focus on the combination of volume, difficulty, and intent rather than volume alone.

Do I need a separate tool for Google keyword research if I already use Helium 10? Yes. Helium 10 is built around Amazon data. For Google search volume and difficulty, you'll need Google Keyword Planner, Ahrefs, Semrush, or a browser extension like Keywords Everywhere.

Why might a keyword rank on Amazon but not on Google? Amazon rankings are driven by sales velocity, reviews, and listing optimization. Google rankings are driven by backlinks, content relevance, and on-page signals. A product that sells well on Amazon doesn't automatically rank on Google — it requires a separate content and SEO strategy.
