If you sell on Amazon, you’ve probably noticed there’s no shortage of “Amazon analytics” tools out there. From sourcing to profitability tracking, there’s a tool for every micro-task. But knowing which one to rely on is another story.

Two names that come up often are SellerAmp and Sellics—both solid in their own right. Yet, when you add Ecominsights to the mix, things start to get interesting. Unlike most tools built for sellers alone, Ecominsights was designed for brands, OEMs, and resellers who need a complete view of the marketplace—not just their own data.

Let’s break them down side-by-side.

SellerAmp: Great for Quick Product Sourcing, Not Deep Analytics

SellerAmp was built for one specific purpose—product sourcing. It’s a fast, Chrome extension-based app that helps Amazon sellers analyze products before they buy.

You can check:

• Buy Box price, fees, and profit margin
  
  
• Estimated monthly sales volume
  
  
• FBA vs. FBM competition
  
  
• Restrictions or hazmat flags
  
  

It’s perfect for retail and online arbitrage sellers who spend hours scanning store shelves or scrolling through wholesale lists.

Strengths

• Lightweight and quick – the Chrome extension is responsive.
  
  
• Real-time FBA calculations – instant ROI and profit estimates.
  
  
• Handy integrations – works with Keepa, BuyBotPro, and Google Sheets.
  
  

Limitations

SellerAmp’s biggest weakness is that it doesn’t scale with your business.
Once you move beyond product-by-product sourcing and need to analyze entire portfolios or competitors, it falls short.

There’s no real market share analysis, no keyword intelligence, and no visibility into who else is selling your brand’s ASINs.

If you’re a brand or agency managing dozens—or hundreds—of listings, you’ll quickly find yourself exporting CSVs and stitching data together manually.

Sellics: Once a Seller’s Favorite, Now Focusing on Advertising

Sellics was once one of the go-to all-in-one Amazon tools. It offered everything from keyword tracking to profit dashboards and review monitoring. But over the past few years, Sellics shifted heavily toward advertising optimization.

Today, Sellics focuses primarily on PPC automation and AI-driven bid management.

It’s now marketed more toward advertisers and agencies than toward traditional sellers.

Strengths

• Solid PPC automation – optimizes bids based on performance data.
  
  
• Historical analytics – helps track ACOS and campaign ROI over time.
  
  
• Strong enterprise support – robust for larger sellers running multiple ad accounts.
  
  

Limitations

• Narrower focus – limited product research and listing optimization tools.
  
  
• Outdated seller dashboards – profit tracking feels clunky compared to newer tools.
  
  
• Lack of competitive visibility – doesn’t reveal who your competitors are or what ASINs they’re targeting.
  
  

So while Sellics remains useful for PPC specialists, it’s no longer the all-in-one solution it used to be.

Ecominsights: Marketplace Intelligence for Sellers, Brands, and OEMs

Now, here’s where Ecominsights comes in—and why it’s quickly becoming the go-to alternative for Amazon professionals who need deeper visibility.

Ecominsights takes everything that tools like SellerAmp and Sellics do individually and connects it across the entire marketplace.

It’s not just about scanning ASINs—it’s about understanding the ecosystem.

Key Capabilities

1. Complete ASIN Intelligence

Ecominsights lets you see every ASIN a seller, brand, or competitor is involved with.
Want to know:

• Which sellers are on your listings?
  
  
• What ASINs those same sellers are also selling?
  
  
• How much revenue each ASIN is generating monthly?
  
  

Ecominsights brings all that into one dashboard.

2. Brand and Competitor Analysis

Instead of just focusing on your products, you can analyze entire brands or reseller networks.

You’ll know:

• How much revenue each brand drives on Amazon
  
  
• Who their top resellers are
  
  
• Which new sellers are entering their space
  
  

That’s data you simply can’t get from SellerAmp or Sellics.

3. Marketwide Product Research

Ecominsights uses real Amazon data (not estimates pulled from keyword tools) to show:

• Fastest-growing ASINs by category
  
  
• Price and rank trends over time
  
  
• Keyword clusters that drive revenue
  
  

For example, if you’re a brand manager at an OEM, you can instantly see which ASINs are growing fastest across your category, which sellers are capturing those sales, and how pricing is shifting.

4. Data-Driven Decision Tools

You can cluster keywords, export data, and build internal dashboards in minutes.
Unlike SellerAmp, which analyzes one ASIN at a time, Ecominsights allows bulk analysis—so you can make portfolio-level decisions fast.

Real-World Example: How a Reseller Uses Ecominsights

Imagine you’re a reseller managing multiple brands.
You want to know:

• Which of your partner brands have unauthorized sellers?
  
  
• Which listings are losing Buy Box share?
  
  
• How your sales compare to the competition?
  
  

With SellerAmp, you’d need to manually check each ASIN—time-consuming and error-prone.
With Sellics, you’d only get partial ad-spend data.
But with Ecominsights, you get a single dashboard showing all your active ASINs, top sellers, and estimated revenue trends.

That’s real decision-making power.

Key Takeaways

• Sellics works for advertisers running complex PPC campaigns.
  
  
• Ecominsights gives a 360° view of the entire marketplace—who’s selling what, where, and how much they’re earning.
  
  

If you’re serious about growing beyond basic product sourcing and into data-driven decision-making, Ecominsights is where the market is heading.
