Keepa Chrome Extension Tutorial for Amazon OA Sellers

1. What Is the Keepa Chrome Extension

Keepa is a price tracking tool that plugs directly into your Amazon browsing experience. Once you install the Chrome extension, a full data chart appears every time you scroll down on any product page.

It pulls historical price data, Best Sellers Rank trends, and seller count history going back months or years. That data is what separates a smart buy from a blind guess.

I do not touch a single product without checking Keepa first. That rule alone has saved me from dozens of bad buys since I started doing online arbitrage full-time.

"Keepa is this tool that you are going to find when you scroll down on the page of any Amazon product once you have the extension."

If you are brand new to OA and still figuring out the business model, start with my complete online arbitrage guide before going deep on tools. The tools make a lot more sense once you understand what you are trying to accomplish.

2. How to Install the Keepa Chrome Extension in 2 Minutes

Go to keepa.com and click the link for the Chrome extension. Add it to your browser, and you are done. The install takes about 90 seconds.

Once it is active, open any Amazon product page and scroll down below the buy box. The Keepa chart loads automatically inside the page. No separate tab, no copy-pasting ASINs anywhere.

The free version works right away with a 10-minute data delay. You will need to create a Keepa account to access paid features, but you can start reading charts immediately after installation at no cost.

3. The Price History Tab: Where Every Sourcing Check Starts

When the chart loads, you land on the Price History tab by default. This is the right starting point. It shows color-coded lines for the Amazon price, the lowest FBA price, and new and used third-party prices over your selected time window.

What you want: a flat or gently rising line. If the FBA price has stayed between $28 and $34 for the past 90 days, you can source around that band with real confidence. That stability is money in the bank.

What you do not want: a chart that looks like a seismograph. Swings from $14 to $45 and back down inside 60 days mean the listing is volatile. You can get caught holding inventory at the wrong price point very fast on listings like that.

"What I understand about Keepa is that basically it shows you the trends. It's historical data. It'll show you how much the product cost over time."

Set your time range to at least 90 days by default. You can do this in the top right of the chart. Ninety days gives you enough history to spot patterns without burying you in noise from two years ago.

4. BSR Drops Are How You Count Sales From the Chart

This is the most valuable insight Keepa gives you, and most new sellers skip past it entirely. Every downward spike on the BSR chart represents one or more units sold. Count the drops per month and you have a real sales velocity estimate.

My read on it: 40+ BSR drops in the last 30 days means the product is moving well. Fewer than 10 drops in 90 days means it is slow, and I pass. I want products that sell at least 20-30 units per month before I commit to a buy.

The category context matters too. A product at BSR 80,000 in Kitchen sells at a completely different rate than BSR 80,000 in Collectibles. For more on how to interpret rank by category, check out my post on Amazon BSR and what sales rank actually means for OA sellers.

Train yourself to look at drops per 30-day window. Scroll across the chart and count consistently. After a few hundred products, it becomes instant pattern recognition.

5. The Seller Count Chart: Spot Crowding Before You Commit

Switch to the "Seller Count" tab in the Keepa chart. This shows how many FBA sellers and FBM sellers have been on the listing over time. It is your crowding early warning system.

I want to see a low seller count that is flat or trending down. If a listing had 28 FBA sellers six months ago and now has 9, competition is clearing out. That is a much healthier environment to enter.

If seller count is spiking upward recently, it often means a deal site featured the product or someone shared it in a sourcing group. A sudden jump from 6 to 30 sellers means the price is about to drop fast. I skip those or wait until it stabilizes.

High seller count combined with a falling price line on the Price History tab is usually a race to the bottom in progress. Keepa lets you see that pattern before you become the person stuck holding the inventory.

6. New, Used, FBA, and FBM Tabs: What Each One Tells You

The Keepa chart has several tabs across the top. Price History is the main one, but FBA, New, Used, and FBM each isolate specific pricing tracks. For OA, the FBA tab is the one you care about most.

The FBA tab shows only what FBA sellers have priced at over time. If FBA prices have stayed in the $26-$31 range for three months, I know exactly what my selling price window is before I source a single unit.

The Used tab matters less for standard OA unless you are working with products that have a meaningful used market. For most FBA OA deals, you are selling new condition, so the Used chart is mostly background noise.

There is also an Earn Money tab for the Keepa affiliate program. Ignore it during sourcing. It has nothing to do with reading product data.

7. How to Read Any Keepa Chart in Under 60 Seconds

Once you have done this a few hundred times, a full check takes under a minute. Here is the exact five-point checklist I run on every product:

• Is Amazon on the listing? A blue price line on the chart means Amazon was selling it. If Amazon is a regular seller here, third-party FBA competition gets tough.
• Is the price stable? A 90-day price range within 20-25% is workable. Bigger swings need a real reason before I proceed.
• How many BSR drops in the last 30 days? Count them. Fewer than 10 is slow. 30 or more is solid for most categories.
• What is the seller count trend? Flat or declining is what I want to see. A spike upward in the last 30-60 days is a red flag.
• Does the ROI math work at the floor price, not the peak? Run your numbers against the lowest price point on the chart, not what it is at right now.

That five-point check takes 45-60 seconds once you have the muscle memory built. Pair it with SellerAmp SAS running at the same time to calculate actual ROI while you read the chart, and you have a complete sourcing decision in under two minutes.

8. The Keepa Product Finder for Sourcing at Scale

"I am going to show you how to use the Keepa product finder. A quick strategy that I'm using myself actually right now that you can actually steal from me. I'm literally giving you guys the strategy that I am using to scale my Amazon FBA business right now."

My Secret Keepa Sourcing Strategy to Scale Online Arbitrage, YouTube 2024

The Keepa Product Finder is a separate database tool on the Keepa website, not the Chrome extension itself. You filter by category, BSR range, price, and seller count to pull a targeted list of products worth investigating.

My go-to filter setup: specific category (Kitchen, Baby, or Sports), BSR under 100,000, FBA seller count under 5, and Amazon price absent. That last filter is critical. If Amazon is not selling it, there is room for third-party FBA sellers to win the buy box.

The output is a list of ASINs that pass those criteria. I then check each one in the Chrome extension to confirm price stability and BSR drops. This reverse-sourcing workflow feeds quality leads without spending hours clicking through retailer sites.

For more on how this fits into a full OA workflow, read my post on online arbitrage sourcing strategies that scale past $10K a month.

9. Stacking Keepa with SellerAmp for Faster Buying Decisions

Keepa and SellerAmp are the two tools I have open on every single sourcing session. They do different jobs. Keepa gives you historical context. SellerAmp gives you real-time profit math on the current price.

My workflow: find a deal on a retailer site, paste the ASIN into SellerAmp to check fees and ROI, then immediately check the Keepa chart to confirm the price history and velocity support the buy. If both pass, I buy. If either fails, I skip.

I walk through this exact two-tool system live every Thursday at 8 PM EST. Grab a free seat at my Thursday training and watch me source, analyze, and ship a real product from start to finish in one session.

10. Keepa Free vs. Paid: What You Actually Need

The free version gives you access to the chart with a 10-minute data delay. For browsing and learning how to read charts, that is fine. For active OA sourcing where you are reacting to deals that disappear in hours, a 10-minute delay is a real problem.

The paid plan costs around $19 per month. It gives you real-time data, full access to all chart tabs, and unlimited Keepa Product Finder queries. Those three things together are what make Keepa worth using at scale.

If you are sourcing more than 10-15 products a week, the $19 is noise. One bad buy you avoid because you had real-time data covers several months of the subscription. And the Product Finder alone is worth the cost if you use it for reverse sourcing.

Start free while you are learning the chart. Upgrade once you are sourcing regularly. That is the practical sequence.

11. Common Keepa Mistakes That Cost New OA Sellers Money

Mistake one: buying based on today's price without checking the history. A product might be at $47 right now but was at $19 three months ago. Keepa shows that history clearly. Looking only at the current price is flying blind.

Mistake two: ignoring the BSR chart and only reading the price tab. Price stability means nothing if the product only sells two units a month. BSR drops tell you if people are actually buying it.

Mistake three: using a 30-day time window on everything. For products where seasonality could be a factor, you need to look at 180 days or a full year. A product that looks healthy in April might crater every July. Keepa will show you that if you look far enough back.

Mistake four: not checking if Amazon is on the listing. If Amazon regularly sells a product and then comes back in at a lower price, your FBA ranking drops and your sales stop. The blue price line on the chart is Amazon. Know where it has been before you decide to compete there.

12. My Keepa System for Scaling OA Past $10K Per Month

When I was scaling from $5K to $30K per month in OA, Keepa was the tool that gave me confidence to go bigger on the best products. If the chart showed 12 months of price stability and 50+ BSR drops per month, I would buy 25-40 units instead of 5. The chart gave me conviction to size up.

That is the real point of mastering this tool. It is not just about avoiding bad buys. It is about giving you the data to go bigger on the good ones without sweating it.

My rule: a product only gets a large buy if it passes all five points from my checklist in Section 7. If it fails even one, I either reduce quantity sharply or skip entirely. No exceptions.

This Keepa-first discipline is one of the core systems I teach in The Scaling Society.
