Media spend was concentrated in Shopping campaigns with limited format testing or segmentation.
Solutions implemented
The operating changes behind the result.
New campaign formats
The strategy expanded beyond Shopping into Search, Performance Max, and complementary formats to improve funnel coverage.
Parallel validation
New campaigns ran alongside the legacy structure for two months so performance could be compared directly.
Performance-driven optimization
Budgets and tactics were continuously adjusted using real-time performance by product and campaign type.
Highlighted results
Better visibility. Better decisions. Better outcomes.
In June, new campaigns produced an 11.34 ROAS while legacy campaigns produced a 0.12 ROAS.
Consolidated account ROAS increased from 0.59 in May to 8.88 in June and remained strong at 8.45 in July.
The source case study reports a 900% ROAS increase in less than two months after restructuring.
Conclusion
Structure, segmentation, broader campaign formats, and real-time optimization replaced a one-dimensional setup with a tested acquisition model designed to scale.
