How a Leading CPG Beauty Brand Improved Amazon ROAS by 28% with SWYM
The challenge
A leading CPG beauty brand, in partnership with its agency, was running Amazon DSP campaigns to drive efficient return on ad spend in a highly competitive category.
Despite strong audience targeting, bidding strategies, and creative execution, performance was constrained by inefficiencies within the programmatic supply chain. A meaningful portion of spend was allocated to lower-quality inventory that failed to convert at the same rate, limiting overall ROAS and suppressing purchase rates.
This challenge became even more pronounced during high-demand retail periods like Prime Day, where increased competition and rising CPMs made it more difficult to maintain efficiency at scale. The team needed a solution that could improve media quality and performance outcomes without disrupting existing campaign structures or increasing budgets.
The solution
The brand and agency partnered with SWYM to address inefficiencies at the source, before bids were placed.
Using AI-powered supply curation, SWYM analyzed real-time commerce signals, including purchase behavior and ROAS performance, and applied these insights directly to bidstream decisioning. Incoming bid requests were dynamically scored across domains, placements, and supply paths to identify inventory most likely to drive conversions.
SWYM prioritized high-performing supply while suppressing low-quality or non-converting inventory upstream. This created a more curated and efficient supply path within Amazon DSP, enabling the team to improve outcomes without changing audience targeting, creatives, or budget allocations.
Additionally, SWYMs real-time optimization capabilities allowed campaigns to adapt quickly during key retail moments, ensuring performance gains were maximized during peak periods like Prime Day.
The results
By applying SWYM’s AI-driven supply shaping and continuous optimization, the campaign achieved:
Increase in ROAS overall
vs. non-SWYM campaigns
Increase in purchase rate
indicating stronger conversion efficiency
Higher ROAS during Prime Day
demonstrating the ability to outperform during peak retail events
The campaign demonstrated how integrating audience intelligence into supply decisioning can simultaneously improve performance, efficiency, and transparency.
