How we helped Ember cut PPC spend by 43% and increase ROAS by 53% in just two weeks

THE CHALLENGE

Budget cuts across all European Amazon Marketplaces

In March 2025, Ember faced a mid-month budget cut across all European Amazon marketplaces, requiring a quick response to reduce PPC spend by over 40% without compromising performance. With only two weeks to act, the challenge was clear: pivot fast, trim costs, and maintain a strong return on ad spend (ROAS).

THE SOLUTION

A lean and effective optimisation strategy

Drawing on our in-depth understanding of Ember’s Amazon advertising landscape, we implemented a lean and effective optimisation strategy:

• Campaign pruning: We paused 37 underperforming campaigns across regions, focusing only on high-performing ASINs and regions..
• Target-level bid optimisation: We reduced bids on expensive or lower-performing ASINs, keywords, and audience segments to drive down CPC.
•  Focus on efficiency: With a better view of what works, we avoided unnecessary experimentation and leaned into proven tactics to maximise returns from a smaller budget.

No creative or content changes were needed; the improvements came entirely from smarter targeting, bid strategy, and campaign structure. These strategic adjustments were applied across all major Amazon marketplaces: the UK, Germany, France, Italy, Spain, and Sweden.‍

THE RESULT

Improved performances across all markets

The impact of our fast optimisation was clear:

• Total PPC spend dropped by 43%;
• Average CPC across all markets fell by 23.8%, from €0.92 to €0.70;
• ROAS improved by 53.3%, increasing from 4.02 to 6.16.

By maintaining the same product range (including Ember’s Mug, Travel Mug, Cup, and Tumbler), we ensured campaign continuity while boosting efficiency through strategic execution.

CONCLUSION

In just two weeks, we helped Ember adapt to a major budget shift with minimal disruption and maximised the efficiency of their Amazon campaigns. This case study highlights how our rapid, data-driven approach allows us to pivot fast, reduce waste, and still deliver high-performance results, even under pressure.
