You're probably staring at a blank spreadsheet right now, wondering why that "guaranteed" winner you found last month is currently sitting in a dusty corner of a Delaware warehouse. It's frustrating. Honestly, the dream of passive income through e-commerce has turned into a bit of a data-heavy nightmare for most people because they’re all looking at the exact same charts. Everyone uses the same Chrome extensions. Everyone filters for the same "high demand, low competition" metrics. If you’re doing what the YouTube gurus told you to do in 2022, you’re basically fighting for scraps in a room full of sharks.
Finding best selling products on Amazon isn't about finding a magic "fidget spinner" before it blows up; it's about spotting behavioral shifts before the algorithm catches up.
The Best Seller Rank (BSR) Trap
Most beginners treat the Amazon Best Seller Rank like a holy grail. They see a product with a BSR of 200 in Kitchen & Dining and think, "Wow, this is a goldmine!" Not necessarily. BSR is a snapshot, not a movie. It tells you how a product is selling right this second relative to others in its category. It doesn't tell you if the seller just ran a massive off-Amazon TikTok ad campaign or if they’re burning through cash with aggressive PPC (Pay-Per-Click) bids just to buy that ranking.
If you rely solely on the current BSR, you’re looking in the rearview mirror. You want to look at the historical stability of that rank. Tools like Keepa are essential here, not for the flashy features, but for the boring price history lines. If a product’s BSR fluctuates wildly like a heart rate monitor after a double espresso, that's a seasonal or trend-heavy item. You want the "boring" products—the ones that maintain a steady, slightly boring rank for eighteen months straight. That’s where the sustainable money is.
Forget "High Demand"—Look for High Friction
Here is a weird truth: the best products are often the ones people complain about the most.

Go to a popular category. Find a product with 4.2 stars. Now, ignore the five-star reviews—those are often biased or just "it arrived on time." Ignore the one-star reviews; those are usually people who had a bad day or a broken box. The three-star and four-star reviews are your actual research department. This is where people say, "I love this garlic press, but the handle is a bit too small for someone with large hands," or "It works great, but I wish it came in a pack of two instead of one."
That "but" is your product development roadmap. Finding best selling products on Amazon is often just a matter of finding a "good" product and making it "exactly what they asked for."
The Rabbit Hole Method
Instead of using a database, try the manual rabbit hole. Start at a "Best Sellers" page for a niche sub-category—something oddly specific like "Industrial & Scientific > Lab & Scientific Supplies > Glassware & Labware."
Why? Because major brands aren't hovering over lab-grade beakers.
Click on a product. Scroll down to the "Customers who viewed this item also viewed" section. Click a related item. Repeat this six times. By the sixth click, you are usually looking at products that don't appear in the top-level search results but have incredibly high conversion rates because the people who find them are desperate for that specific solution. This is how you find items with zero "flash" but high utility.
Using Amazon’s Own Data Against Itself
Amazon actually gives you the answers; they just hide them in plain sight. Have you ever looked at the "Frequently Bought Together" section? That is literally Amazon's A.I. telling you: "Hey, people who buy X are annoyed they don't also have Y."
If you see a yoga mat frequently bought with a specific type of cleaning spray, don't just sell the mat. Sell a bundle. Or better yet, find a way to incorporate the cleaning solution into the mat's packaging. You're no longer just finding a product; you're creating a market outlier.
The "Movers and Shakers" Secret
The Movers and Shakers tab is updated hourly. It shows the biggest gainers in sales rank over the last 24 hours. Most people check this once and move on. The pro move? Check it every day at the same time for a week. Document which items appear repeatedly. If a specific type of ergonomic mouse pad keeps popping up on the Movers and Shakers list across several days, it’s not a fluke. It’s a trend starting to boil.
Negative Space: What’s Not There?
Sometimes finding best selling products on Amazon involves looking for what is missing. Look at "New Releases." If you see a surge in a specific type of aesthetic—say, "Cottagecore" home decor—but you notice there are no functional kitchen items in that style, you’ve found a gap.
Search for keywords on Amazon that have high search volume but low "sponsored" presence. If you type in a specific term and the top three results aren't ads, that means the big players haven't bothered to bid on that keyword yet. That is a massive green flag.
Real-World Constraints and the "Boring" Filter
Let's talk about the "Oversized" headache. Everybody wants to sell small, light things because shipping is cheap. But because everybody wants that, the competition is insane. If you are willing to deal with the logistics of a product that is slightly heavy or awkwardly shaped, your competition drops by about 70%.
I'm not saying sell couches. I'm saying look for the "un-sexy" items:
- Replacement parts for specific lawnmower brands.
- Specialized organizational inserts for deep kitchen drawers.
- Heavy-duty weatherproofing kits for specific RV models.
These aren't "cool." You won't brag about them at a dinner party. But the margins are often double what you'd see on a generic "lifestyle" product.
Actionable Steps to Take Right Now
Stop scrolling through TikTok "Product Finds." That ship has sailed by the time you see the video. Instead, do this:
- Open Amazon's "Opportunity Explorer" (if you have a Seller Central account). Look for "Niche View." Pay attention to the "Search Conversion Rate." If a niche has high search volume but the top products only have a 2% conversion rate, it means the current products suck. That's your opening.
- Audit the "Customers Also Search For" keywords at the bottom of a search results page. These are the lateral moves. If you're looking at "Resistance Bands," and Amazon suggests "Physical Therapy bands for seniors," you just found a more profitable, targeted sub-niche.
- Check the "Gift Ideas" section. This is a goldmine for bundles. People buying gifts are less price-sensitive and more "convenience-sensitive." They want the "all-in-one" solution.
- Verify with external data. Use Google Trends to make sure the product isn't dying. If the 5-year trend for "Hydroponics" is a steady 45-degree angle upward, it's a safe bet. If it looks like a mountain peak that already passed, stay away.
The "best" product isn't the one with the most sales. It's the one with the most defensible sales. Find a product where you can explain why it's better than the top seller in one sentence. If you can't do that, keep digging. The data is there; you just have to stop looking where everyone else is pointing.
