Why You Should Avoid Selling Best Seller Products on Amazon
Pouyan Pazargadi
When most beginners start their Amazon journey, they search for the top-ranking items and think, "If it's selling well, I should sell it too." It sounds logical, but chasing Amazon best seller products is one of the fastest ways to lose money as a new seller.
The truth is, best sellers look attractive from the outside, but behind the scenes they are crowded, expensive, and dominated by experienced sellers with deep pockets. As a beginner, you simply can't compete on the same playing field.
In this article, you'll learn exactly why selling Amazon best seller products is risky for new sellers, the hidden costs you don't see in the rankings, and a smarter approach to picking profitable products that actually give you a chance to win.

1. The Competition Is Brutal for Beginners
Amazon best seller products attract thousands of sellers worldwide. Every time a product hits the top of a category, dozens of new sellers jump in trying to copy the success. This creates a saturated marketplace where standing out becomes nearly impossible.
Here's what you're actually competing against:
- Established brands with years of reviews and loyal customers
- Big-budget sellers running aggressive PPC campaigns
- Chinese manufacturers selling directly with razor-thin margins
- Private label veterans who already optimized their listings
As a beginner, you don't yet have the experience, capital, or review base to break into the top 10 results. Even if your product is identical in quality, buyers will choose the listing with 5,000 reviews over yours with zero.
Action step: Before picking any product, search the main keyword on Amazon. If the first page is filled with listings that have over 1,000 reviews, walk away. You're entering a battle you can't win in your first year.
2. Profit Margins Are Squeezed to the Bone
Best seller products trigger price wars. When everyone is fighting for the Buy Box, sellers keep dropping prices until margins disappear. What looks like a high-revenue product often produces almost no profit.
Let's break down a typical best seller cost structure:
- Product cost: 25-35% of selling price
- Amazon FBA fees: 15-20%
- Referral fees: 8-15%
- PPC advertising: 15-25% (often higher in saturated niches)
- Returns and refunds: 3-5%
Add it all up, and you're often left with 5-10% net margin—if you're lucky. One bad month of returns or rising ad costs and you're losing money on every sale.
Action step: Before launching any product, calculate your full landed cost using Amazon's FBA Revenue Calculator. Aim for products with at least a 30% net profit margin after all fees. Best sellers rarely meet this threshold for new entrants.
3. Advertising Costs Will Drain Your Budget
In crowded categories, the only way to get visibility is through Amazon PPC. But here's the problem—when everyone bids on the same keywords, cost-per-click skyrockets.
In top categories, you might pay:
- $3-$8 per click for competitive keywords
- 50-100+ clicks before getting one sale
- $150-$500 in ad spend just to land a single conversion
For beginners with a $2,000-$5,000 starting budget, this is unsustainable. You'll burn through your capital before your listing gains organic traction.
Meanwhile, established sellers can absorb high ad costs because they've already recovered their investment. They use ads to maintain rankings, while you're using ads just to be seen.
Action step: Instead of jumping into best seller categories, look for products where the top 3 keywords have a CPC under $1.50. Use tools like Helium 10 or Jungle Scout to verify ad costs before sourcing inventory.

4. You'll Be Trapped in a Review War You Can't Win
Reviews are Amazon's currency. Best seller products typically have thousands of reviews built up over years. As a new seller, getting your first 50 reviews can take months—and Amazon's strict policies make it slower than ever.
Why this matters:
- Buyers filter products with under 4 stars
- Listings with under 50 reviews rarely convert above 5%
- Amazon's algorithm favors listings with consistent review velocity
- Competitors with 1,000+ reviews dominate the Buy Box
Even if your product is genuinely better, the review gap creates a trust gap. Customers don't take chances on unproven sellers when a "safe" option with 3,000 reviews sits right next to yours.
Action step: Pick categories where the top sellers have 100-500 reviews instead of thousands. This gives you a realistic path to compete within 6-12 months using Amazon Vine and natural review generation.
5. Trends Change Fast and Inventory Becomes Dead Weight
Many Amazon best seller products are riding a trend. By the time you spot it, manufacture it, ship it, and list it, the trend is already cooling down. Beginners often order 500-1,000 units of a "hot" product, only to watch sales drop while inventory sits in FBA warehouses racking up storage fees.
Common trend traps include:
- Seasonal items that peak then crash
- TikTok viral products with 60-day lifespans
- Copycat trends flooded by competitors within weeks
- Holiday-specific products that miss the shipping window
Long-term FBA storage fees can cost more than the product itself. Many beginners end up paying Amazon to remove or destroy unsold inventory.
Action step: Choose evergreen products with stable 12-month sales history. Use Keepa or Helium 10's Trendster to verify that demand has been consistent for at least 18-24 months before investing.
6. The Smarter Strategy: Find Profitable Sub-Niches
Instead of chasing Amazon best seller products, beginners should target underserved sub-niches where competition is manageable and demand is real. These are often called "low-competition, medium-demand" products.
A good beginner product looks like this:
- Monthly sales: 300-1,000 units across the top sellers
- Reviews on top listings: Under 500
- Selling price: $20-$50 (sweet spot for margins)
- Lightweight: Under 2 pounds to keep FBA fees low
- Simple design: No electronics, no breakables, no legal risks
- Differentiation possible: Bundle, improve quality, or upgrade packaging
Examples include niche kitchen tools, hobby accessories, pet items for specific breeds, or solutions to a specific problem (not a category as a whole).
Action step: Spend 2-3 weeks doing product research with proper tools. Build a shortlist of 20 potential products, then narrow it down using competition, margin, and demand criteria. Quality research beats quick decisions every time.
Conclusion
Selling Amazon best seller products feels like the obvious move, but it's a trap for beginners. The competition is too strong, margins are too thin, ad costs are too high, and the review gap is nearly impossible to close in your first year.
Here's what to remember:
- Best sellers are dominated by experienced, well-funded competitors
- Profit margins are squeezed by constant price wars
- PPC costs in top categories will drain your starting capital
- Building reviews takes months you don't have
- Trends die fast and leave you with dead inventory
- Sub-niches offer the real opportunity for new sellers
Your next step: Forget the best seller list. Open a product research tool, set filters for under 500 reviews, $20-$50 price range, and consistent 12-month sales. Build your shortlist from there. That's where beginners actually win on Amazon.

Frequently Asked Questions
Why should I avoid selling Amazon best seller products as a beginner?
Amazon best seller products usually have intense competition from established sellers with bigger budgets, better reviews, and lower supplier costs. As a beginner, you'll struggle to rank, spend heavily on ads, and likely lose money before gaining traction. It's smarter to start in a less crowded niche where you can actually compete.
Are Amazon best seller products always profitable to sell?
No, best sellers often have thin profit margins because so many sellers undercut each other on price. After Amazon fees, PPC ads, and shipping costs, you may end up breaking even or losing money. High sales volume doesn't guarantee profit, especially in saturated categories.
What happens if I try to compete with top-ranking Amazon sellers?
You'll face sellers with hundreds or thousands of reviews, optimized listings, and strong brand recognition. Breaking into the top results requires aggressive advertising spend and deep discounts, which most new sellers can't sustain. Many beginners burn through their budget before making a single profitable sale.
Is it better to sell low-competition products instead of best sellers?
Yes, low-competition products with steady demand give beginners a real chance to rank, build reviews, and earn profit. You don't need to sell thousands of units to make good money if your margins are healthy. Finding underserved niches is one of the smartest strategies for new Amazon sellers.
How do I know if a product is too competitive to sell on Amazon?
Check the top 10 listings for review counts above 500, multiple branded sellers, and very low prices. If the BSR is extremely high but margins look tight after fees, it's a red flag. Tools like Helium 10 or Jungle Scout can help you analyze competition before investing.
