Keepa Product Finder Tutorial for OA Sellers

1. What Keepa Product Finder Does

Keepa Product Finder lets you filter Amazon's product database instead of scrolling it. You set conditions like brand, category, sales rank, price and who sells on the listing, and Keepa returns every product that matches.

For online arbitrage, that turns a vague question ("what can I flip?") into a short list you can check against a retailer's sale.

"If you do not understand what the Keepa product finder is, it's a tool that allows you to filter the database of product on Amazon pretty much, right? And so I'm going to filter the database of products for Gap products that Amazon is not selling, right? And there are 66,000 products."

The Exact System I Use to Find Winning Arbitrage Products on Amazon

66,000 results is too many to work. The rest of this tutorial is about cutting that number down to something you can source in one sitting.

2. Product Finder vs Storefront Stalking

Storefront stalking starts from another seller's buys. Product Finder starts from the catalog. You don't wait for a competitor to find the deal first, so you avoid showing up two weeks late to a product that already tanked.

The tradeoff: a storefront tells you someone bought the product. Product Finder only tells you the product exists and fits your filters. You still do the validation yourself.

I run both. If you want the storefront side, read Amazon storefront stalking and reverse sourcing.

3. Start From a Live Sale, Not From the Finder

Most people open Product Finder with no target and drown. Flip the order. Find a retailer running a brand-wide promotion first, then use the Finder to pull every Amazon listing for that brand.

"We're going to use the Keepa product finder to look at all of their brands, all the products for their brands because we know that there's a big promotion on all the products from their brand, right?"

Find Amazon Products That Actually Sell Fast

A sale gives you a buy cost. The Finder gives you the Amazon side. Put the two together and you have leads instead of a spreadsheet of maybes. The OA buy list framework shows where this fits next to your other methods.

4. Filter 1: Brand and Category

Type the brand that's on sale into the brand field. If the retailer's promotion covers one department, add the category too. Narrow early: a brand filter alone can drop tens of thousands of results to a few hundred.

Watch for brand name variations. Some listings use the parent company name or a sub-brand, so run two or three spellings if the count looks low.

Keepa updates its interface, so the exact field labels can move around. Match the idea, not the button position.

5. Filter 2: Sales Rank and Price

Set a sales rank ceiling so you only see products that move. In my own sourcing filters I've used "below 150,000 in sales rank" as a starting cut. Tighten or loosen it by category, since a 150,000 rank means different things in Toys and in Tools. The good BSR guide covers how to set this by category.

Add a price floor too. Low-priced items get eaten by FBA fees, and from October 15, 2026 to January 14, 2027 Amazon charges its peak-season fulfillment fees on top. Run any cheap item through the FBA calculator before you get attached to it.

6. Filter 3: Products Amazon Isn't Selling

Exclude listings where Amazon is an offer. When Amazon sits on the listing, it often holds the Buy Box and drags the price down whenever it restocks. Filtering Amazon out is the single biggest quality jump you'll get from the Finder.

That doesn't mean Amazon never shows up later. Amazon can come back to a listing at any time, so check the Keepa offer history on every finalist, not only today's offer list.

7. Filter 4: Offer Count

Set a minimum and a maximum on the number of FBA offers. Too few offers can point to a gated brand, a hazmat flag or a dead listing. Too many and your share of the monthly sales gets thin.

A rough check: estimated monthly sales divided by the number of FBA sellers gives your realistic share if you match the Buy Box. If that number won't move your units in 30 to 45 days, skip it. How many units to buy walks through the math.

8. Export the Results and Work Them in Batches

Once the list is under a few hundred products, export it. Sort by sales rank and work the top of the list first.

"You have some people that are going to say, 'Hey, look, I'm going to use the Keepa product finder, export that, run that through to Tactical Expander. Then from Tactical Expander, I'm going to run it to Tactical Arbitrage. It's going to return me a lot of leads, all that stuff.' You don't need to do all that."

I Found The BIGGEST Mistake People Make With Online Arbitrage

When you start from a live sale, the matching step is short. You already know the retailer. Search the product on that site, plug in the sale price and check the numbers. Save the multi-tool chains for later, once you've worked the easy wins.

9. Check Every Hit Before You Buy

A Finder result passed four filters. That's a candidate, not a buy. Before you order, check:

• The Keepa price history for the last 90 to 180 days, so a temporary spike doesn't fool you (how to read Keepa graphs)
• Whether you can sell the brand and category on your account (check if you can sell it)
• Net profit after referral, fulfillment and inbound placement fees, plus your prep center's per-unit cost
• Whether the product is hazmat or meltable

Since the end of commingling on March 31, 2026, every unit you send needs an FNSKU label unless you're the Brand Representative. Count that labor or prep center cost in your numbers.

10. Product Finder Timing in Late October

This post goes up October 25. Most of Amazon's BFCM arrival dates are behind us and the last one is days away, but Christmas demand is still ahead. My own rule for this season: aim for FBA arrival by November 20 and treat December 1 as the last call.

That means Finder leads you buy this week should ship to your prep center fast. If a product won't make it, consider merchant-fulfilled for those units. FBA vs FBM breaks down the tradeoff.

11. Where Product Finder Stops

Product Finder knows the Amazon side. It doesn't know which retailer is discounting today, and it doesn't tell you when a competitor adds a fresh product. You still need a sale to start from and a way to see what other sellers are buying.

For the second part I built Arbitrage Stalker. It tracks seller storefronts and alerts you when they add a new product, so you see new buys without checking each storefront by hand.
