How Amazon Agency Coretrex Slashed Client TACoS by 50% and Increased Profitability by 6% with Helium 10 Ads 

Introduction

Coretrex is a full-service Amazon and Walmart agency focused on revitalizing small and mid-sized businesses. They operate with the mindset to “be unforgettable” to their clients, emphasizing both speed and stewardship. We spoke with Bobby Browning, Brand Growth Manager at Coretrex, to learn how Helium 10 helps them manage advertising across diverse brands—giving them the flexibility to tailor optimizations at scale.

The Challenge:

Coretrex’s primary challenge was the sheer volume of daily optimizations needed across multiple client accounts. Manual processes were not sustainable, and they required a solution that could automate efficiently. Additionally, they needed a more powerful keyword discovery process to complement their in-campaign harvesting strategy to ensure no opportunity was missed. Finally, deep performance insights were essential to diagnosing conversion issues—especially for brands where traffic was strong but not translating into sales.

“This is an incredibly powerful tool. We’re a small team, but Helium 10 makes us feel and operate at a much broader, more strategic level.”
Bobby Browning, Brand Growth Manager

Solution:

Coretrex adopted Helium 10 to unify their keyword research and advertising automation within one connected platform. 

Using Helium 10 Ads, they set up automated keyword harvesting, pulling high-performing search terms from broad and auto campaigns into their high-intent “impact” and “precision” campaigns. This system was paired with Helium 10’s keyword research tools—specifically Cerebro for competitive reverse ASIN lookups and Magnet for keyword discovery—which helped identify overlooked seasonal and niche keyword opportunities. 

To optimize in real time, the team monitored keyword trends using Keyword Tracker and adjusted targeting accordingly. Their campaign performance was further fine-tuned using Helium 10’s customizable bid automation rules, allowing the small team to manage large-scale changes quickly and efficiently. 

“Because of keyword harvesting and our bid automations, we were able to cut their TACoS in half—from 30% to 15%—all while increasing profitability, in about two weeks.”

Results

With Helium 10, Coretrex transformed its ad operations. The team now executes thousands of campaign changes daily—an effort that would be impossible manually. The platform allowed them to operate at a broader, more strategic level while delivering an elevated level of service to clients. 

In one standout case, Coretrex helped a newly onboarded brand cut its TACoS from 30% to 15% in just two weeks. By restructuring over 50 manual campaigns and implementing automated keyword harvesting and bid rules, they increased impressions, click-through rate, and conversions—all while improving profitability, and without adding headcount. 

“We’re fine tuning thousands of bids and targets per day on every account, and that wouldn’t be possible on our own.”
