As an Amazon seller, you can’t escape this question: what actually makes a “good product”? Especially if you’re doing private label — if you don’t have a clear standard for this, your product development will be all over the place.

Let’s be real: the market’s getting brutal. Everyone’s racing to the bottom on price, and it’s hard to keep up. So how do we pick products that let us not just survive, but actually make money? Product development is the backbone of any Amazon business — it’s what determines whether you’re profitable or not.

I’ve spent the last few months obsessing over this. Talked to my team, bounced ideas off other sellers, and put together a framework that’s worked for us. Full disclosure: I’m not a “professional product developer” — I started in operations. But after 6 years in Amazon (seen my share of wins and fails), and tons of conversations with other sellers, I’ve got a pretty solid take on what works.

Here’s my framework. Would love to hear other perspectives — no one has all the answers, and I’m always down to learn.

Different ways to think about "good product"

1. A good product has competitive advantages

Three non-negotiables (but they’re often conflicting — that’s the tricky part):

  • Price advantage: Straightforward — you need to be able to compete on cost, without killing your margins.

  • Differentiation: Doesn’t have to be huge. Could be a small design tweak, a better material, or a missing feature competitors are sleeping on.

  • Good quality: Your rating needs to hold up — 4.3+ stars for most categories, otherwise you’ll get killed by bad reviews.

Here’s the catch: these three often fight each other. A new “differentiated” feature might backfire (unexpected bad reviews if it’s untested). Better quality and custom features cost money, which eats into your price advantage.

Hitting all three? That’s a potential home run. But let’s be honest — that’s rare. Your job as a developer is to find the sweet spot: not too expensive, not over-differentiated, but a balance of cost, quality, and uniqueness.

2. A good product has low competition and large market space

Everyone says this — but how do you actually find it? Low competition and big market space are opposites. With all the tools (Helium 10, Jungle Scout) and information out there, it’s almost impossible to find a “hidden gem” that’s both big and untapped.

If you do find one? It’s either got barriers to entry or major risks.

What counts as a barrier? Two main types:

  • Regulated products or patents: Think medical devices, pesticides, etc. You need resources, connections, and guts to break into these. I’ve heard stories of sellers dropping millions on medical certifications during COVID — and making it back fast. Others have built entire businesses on a single patented product, cashing in on long-term high margins.

  • Deep specialization: Building your own moat over time. This means doubling down on a niche, mastering your brand, refining your technology, understanding your customers better than anyone else, and building an efficient team. It takes time and patience — not for get-rich-quick sellers.

If you go the specialization route, check three things first: market size (and room to grow), how easy it is to differentiate, and industry trends (avoid declining categories — don’t climb a ladder that’s leaning against the wrong wall).

3. A product that makes money is a good product

Sounds obvious, right? But let’s get practical — here’s a formula I use to filter products.

From an operations angle: a good product shouldn’t lose money even if every sale comes from ads. Here’s the math (super simple):

ACOS = CPC / (CVR × Price)

Most sellers have a profit margin (including ad budget) of 25-35% — let’s use 30% as a baseline. If your ACOS hits 30%, you break even. You can look up CPC and average category CVR in Brand Analytics, then reverse-engineer the price point that works.

Of course, many products have ACOS above 30% — that’s where your judgment comes in. But this formula helps you filter categories and price ranges fast, so you don’t waste time on duds.

Another angle: go hyper-niche. I know sellers who focus on products that only do 2-3 units a day — but they have dozens of these listings. It’s a “curated multi-ASIN” strategy (not, but targeted niche coverage). It avoids the red ocean, and over time, the daily profits add up.

Final thoughts

Every seller has their own product selection logic. There’s no “best” method — what works for you (your budget, team, resources) is the right one. I hope this framework helps someone out there — I wish I had something like this when I started.

If you’ve got a different approach that’s working, drop it in the comments. The more we share, the better we all get.
