The Challenge

MobiSystems is a well-established software company known for their PDF and Excel alternatives. Their products had strong market fit, but their Amazon advertising was hemorrhaging money. Some products were running at ACOS over 100%—meaning they were losing money on every ad-driven sale.

The frustrating part? They had already tried everything. In-house management couldn't crack it. Third-party automation tools didn't help. Previous agencies had failed to deliver results. With a target ACOS of around 60%, they were still stuck at 65%+ with no clear path forward.

What they needed wasn't just optimization—they needed someone to diagnose the root problems and fix the foundation before any scaling could happen.

What Had Already Failed

  • In-house campaign management
  • Third-party automation tools
  • Previous agency management
  • Generic bid optimization

The Core Problems

  • !Products with 100%+ ACOS — Some products were fundamentally unprofitable to advertise and were dragging down overall performance
  • !Poor campaign structure — Campaigns weren't organized in a way that allowed for effective optimization at the product level
  • !No product-level strategy — All products treated the same regardless of their individual profitability potential

Our Approach

Instead of applying more optimization to a broken system, we started by diagnosing the root causes. The solution required fixing the foundation before any scaling could happen.

The Fix

1

Diagnosis

Identifying the Problems

Conducted a comprehensive audit of all campaigns. Identified products with ACOS over 100% that were dragging down overall performance. Analyzed campaign structure, keyword targeting, and bid strategies to find the root causes of inefficiency.

2

Restructuring

Fixing the Foundation

Paused or restructured campaigns for chronically underperforming products. Rebuilt campaign architecture with logical segmentation. Implemented proper negative keyword strategies and match type separation to eliminate wasted spend.

3

Optimization

Scaling Profitability

With the foundation fixed, focused on scaling the profitable campaigns. Implemented systematic bid optimization and budget allocation based on product-level profitability. Achieved sustained ACOS below the 60% target.

The Lesson

Sometimes the problem isn't optimization—it's strategy. No amount of bid adjustments will fix campaigns built on a flawed foundation. Before scaling, you need to:

  • Identify which products can actually be profitably advertised
  • Structure campaigns to enable product-level decisions
  • Cut losses on products that will never hit targets
  • Focus resources on what's actually working

“After trying everything—in-house management, automation tools, other agencies—they finally fixed our ads and brought ACOS under our 60% target.”
