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.

Diagnosis
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.
