How I Used Ecominsights to Uncover My Competitor’s Best-Selling Products

When you’ve been selling on Amazon long enough, you start realizing that success isn’t just about finding a product—it’s about finding the right product before everyone else does. A few months back, I hit a point where my usual product research tools weren’t giving me that edge anymore. That’s when I started using Ecominsights.io, and it completely changed how I spy on competitors (ethically, of course).

This post breaks down exactly how I used Ecominsights.io to uncover my competitors’ best-selling products, what I discovered along the way, and how you can use it to sharpen your Amazon strategy.

Why I Started Using Ecominsights.io

I’ve tried almost every Amazon research tool out there—Jungle Scout, Helium 10, SellerApp—you name it. Most of them gave me sales estimates, keyword data, and product scores. But what I really wanted was deeper intelligence: real-time visibility into my competitors’ sales movements, not just estimates.

Ecominsights.io stood out because it focuses on market tracking and competitor insights rather than just keyword scraping. It doesn’t just show what’s selling well—it shows who is selling well, how they’re performing week over week, and why. That’s the kind of data that helps you stop guessing and start strategizing.

Step 1: Finding My Competitors on Ecominsights.io

The first thing I did was input a few ASINs from products in my niche. Let’s say I sell ergonomic office chairs. I entered one of my main competitors’ ASINs, and within seconds, Ecominsights pulled up their entire product portfolio, including pricing history, estimated daily sales, and even new launches.

What impressed me most was how easy it was to see patterns. For example:

One competitor had quietly launched a slightly smaller version of their best-seller at a 15% lower price.
Another was running recurring discounts every 20 days like clockwork.

That level of granularity made me realize just how much I’d been missing before.

Step 2: Identifying Their Best-Selling Products

Here’s where things got interesting. Under the “Competitor Overview” tab, Ecominsights shows sales performance graphs over time—daily, weekly, monthly. You can literally spot when a competitor’s product starts to take off.

One competitor in my niche had a listing that suddenly spiked in sales in mid-August. I checked the trend and saw a 35% sales increase in less than two weeks. Curious, I clicked deeper and noticed they had added a new set of images and re-optimized their title with a trending keyword: “lumbar support.”

That insight alone led me to adjust my own listing title and A+ content, and within a week, my organic traffic jumped noticeably.

Step 3: Using Data to Reverse-Engineer Their Strategy

Once I identified which products were performing best, I used Ecominsights.io’s keyword tracking and price trend features to understand why.

Keyword Trends: I could see exactly which search terms were driving sales to those listings. For instance, “mesh office chair for back pain” was trending up by 40%.
Price Monitoring: I noticed competitors who maintained stable prices through Q3 had better ranking consistency compared to those who relied on flash discounts.
Sales Velocity: I could see how quickly a product was selling after restocks—a great way to gauge inventory turnover.

It wasn’t just data—it was a story about how the market was moving.

Step 4: Taking Action

With those insights, I adjusted my own strategy:

Re-optimized my listings with competitor-performing keywords.
Staggered my discounts instead of running them back-to-back.
Introduced a lower-priced variation of my main product to match what my competitor was doing successfully.

Within two months, my sales volume was up 28%. That’s when it clicked—Ecominsights.io isn’t just for tracking competitors; it’s a tool for understanding them.

What Makes Ecominsights.io Different

Unlike traditional product research tools, Ecominsights.io focuses on:

Real-time competitor analytics (you can literally see day-by-day sales shifts).
Market-wide visibility (track entire categories, not just one product).
Smart alerts (get notified when competitors change prices, keywords, or BSR trends).

It’s like having a data analyst watching your competitors while you focus on scaling your store.

Key Takeaways

Competitor analysis matters. It’s not about copying; it’s about learning from what works.
Ecominsights.io gives context, not just data. You see why a product is performing, not just that it’s performing.
Timing is everything. Spotting a trend even a few weeks early can give you a serious edge.
Data only matters if you act on it. Use what you find to tweak listings, pricing, and promotions strategically.
