The challenge

Despite having a strong product and brand foundation, MiniBrew faced performance inefficiencies within its Amazon PPC campaigns.

Before partnering with eStore Factory, the brand was experiencing:

• High ACoS (47.20%), indicating inefficient ad spend

• PPC budgets spread across campaigns that were not consistently converting

• Wasted spend from irrelevant search terms and targets

• Limited scalability due to poor profitability control

The most important win here is not just higher sales, but much better control over ad spend and profitability. To fix this, MiniBrew turned to eStore Factory for strategic Amazon pay-per-click advertising management focused on efficiency, clarity, and scalable performance.

The solution

eStore Factory implemented a focused, data-driven PPC strategy with one clear goal: to eliminate wasted spend and redirect ad investment toward high-intent traffic that converts consistently. Instead of increasing budgets blindly, we rebuilt PPC around performance, efficiency, and scalability.

1. Reallocated the budget to what actually converts

We conducted a deep, campaign-level performance analysis to identify which campaigns were driving profitable sales and which were draining budget without meaningful returns. 

Budgets were then shifted away from low-impact campaigns and redirected toward high-performing campaigns with strong conversion rates and healthy ACoS. This ensured every dollar spent worked harder, immediately increasing PPC revenue without increasing inefficiency.

2. Cut wasted spend with strategic negative targeting

To tighten traffic quality, we implemented negative keywords and targets across campaigns. This removed irrelevant search terms that were generating clicks but not conversions.

By eliminating low-intent traffic, we reduced wasted ad spend, improved conversion efficiency, and created a cleaner data set for future optimizations, directly contributing to a lower ACoS.

3. Continuous bid & budget optimization for sustained growth

Rather than treating optimization as a one-time task, campaigns were actively monitored and adjusted on an ongoing basis. Bids were refined based on performance trends, and budgets were rebalanced regularly to maintain momentum on winning terms.

This allowed PPC to scale in a controlled way, ensuring increased spend translated into increased revenue without sacrificing profitability.

4. From cost center to scalable growth channel

This structured, performance-led approach transformed MiniBrew’s PPC from a high-cost, inconsistent channel into a predictable and scalable revenue driver. Every optimization decision was tied to clear performance signals, allowing MiniBrew to grow paid sales while significantly improving efficiency.

The results

After optimization in November 2025, MiniBrew saw measurable improvements across key PPC and revenue metrics.

Key insights

• Total sales increased by 7%, showing overall revenue growth

• PPC sales grew by 48%, becoming the primary driver of revenue

• ACoS dropped by 17.41 percentage points, significantly improving profitability

By tightening targeting and reallocating spend strategically, MiniBrew achieved higher PPC revenue with substantially lower advertising costs and higher ad efficiency.
