Amazon PPC Case Study: How We Doubled Seller Revenue in Just 100 Days

Running an Amazon business is not easy; it requires the right products, the correct pricing, and, most importantly, the right advertising strategy. Most sellers spend money on advertising without seeing much profit.

That is where eCom Managers, with their unique approach to Amazon PPC, make all the difference. In the following case study, we demonstrate how our distinct strategy helped one of our clients double their sales in just 100 days using brilliant PPC campaigns, data analysis, and automation tools.

What was the problem?

Before partnering with eCom Managers, the seller was grappling with a few issues that Amazon sellers commonly face:

Low visibility: their products were buried under thousands of listings.

High ad spend: They were paying too much per click, resulting in very few sales.

Poor targeting: ads were shown to people who weren’t actually interested.

No data tracking: they didn’t know which keywords were working.

The client requested more traffic, better conversions, and actual profit—not just clicks.

The eCom Managers Solution

The team at eCom Managers started with a full Amazon PPC audit. They studied every part of the account—campaigns, keywords, and product listings—to identify weak points.

Then, a new data-driven strategy was developed that included:

Keyword Optimization: Found high-converting, low-cost keywords that buyers were actually searching for.

Ad Restructuring: Organized campaigns into clearly demarcated groups like Sponsored Products, Brands, Display, and even Sponsored TV ads.

AI-Powered Bidding: Leveraged automation tools to adjust bids daily to save ad spend and boost conversions.

Listing Enhancements: Better product titles, bullet points, and images matching keywords in ads.

Performance Tracking: Compose weekly reports and live dashboards so the seller can always check results.

This mix of human expertise and AI tools created an efficient, profitable PPC system.

After 100 Days, the Results

The difference was remarkable.

After 100 days of working with eCom Managers, the results looked like this:

Revenue Increased by 2X: Sales doubled compared to the previous three months.

35% Reduction in Ad Spend: Better targeting and automation saved them a lot.

ACOS improved by 42%:  Ads became more profitable.

Organic Sales Increased: Products started ranking higher even without ads.

These results showed that when PPC is done right, not only are sales increased, but your overall Amazon brand performance improves as well.

What We Learned from This Case

From this project, both the seller and the team at eCom Managers learned some very valuable lessons:

Data is Key: Guessing doesn’t work in PPC. You need to know which keywords convert. Understanding and utilizing this data is crucial for a successful PPC strategy.

Optimization Never Stops: Amazon ads require daily checks and adjustments.

Balance between AI and Human Touch: Automation helps, but expert strategy delivers real results.

Better Listings = Better Ads: Even great ads fail if your product listing isn’t optimized.

How eCom Managers Continue to Help

And even after hitting the 2X growth target, the eCom Managers didn’t stop there; they continued to monitor, test, and optimize campaigns week in, week out, providing the seller with ongoing support and guidance.

Results also included helping the seller expand into new Amazon markets, including the UK and Canada, while maintaining a low ACOS. The agency now manages the entire ad strategy, freeing up more of the seller’s time to focus on inventory and customer service.

That’s the benefit of working with a professional team: less stress and more profit.

Why Amazon PPC Works Better Than Other Platforms

• What’s unique about Amazon PPC is that it reaches buyers ready to purchase. Unlike Google or Facebook, where people are just browsing, Amazon users are already looking for a product.
• That means every click on your ad has a higher chance of becoming a sale. And when you combine innovative PPC management with strong product listings, the growth can be massive — just like in this case study.
• This is why agencies like eCom Managers focus entirely on Amazon: the platform delivers tangible, measurable results for sellers.
