month-over-month revenue surge
highest-ever ROAS



The Challenge
The beloved brand, 3 Corações, experienced a sudden and dramatic collapse in return on ad spend (ROAS), plummeting from a ROAS of 13 to 5. Despite rigorous analysis of bidding strategies, audience segmentation, and creative execution, the cause remained elusive—until we uncovered a seismic shift in how consumers were engaging with products online. Traditional keyword-driven search was no longer enough.
The solution required a complete reinvention. We pivoted from keyword-based targeting to AI-powered contextual advertising, embedding 3 Corações into consumers’ digital journeys at the precise moment of intent. Leveraging Amazon’s native technology, we delivered ads based on real-time browsing behavior, content consumption, and engagement patterns.
The impact was extraordinary. Not only did 3 Corações recover, but it reached its highest-ever ROAS of 17, with a 50% month-over-month revenue surge, proving that context beats keywords in the modern digital landscape.

The Execution
Precision was key. Every aspect of the campaign was carefully orchestrated to ensure seamless integration into consumers’ browsing experiences. Using Amazon’s advanced audience mapping tools, we pinpointed the moments of highest engagement and adjusted placements accordingly.
The implementation unfolded in deliberate phases. First, we conducted a thorough behavioral analysis, mapping out digital pathways where coffee-related engagement was strongest. Next, we optimized ad placements across high-intent pages, ensuring that consumers encountered 3 Corações at the exact moment they were considering a purchase. From there, real-time automated adjustments allowed bids and messaging to respond dynamically to shifting consumer trends, guaranteeing that spend was always allocated efficiently.
The final phase was scaling up, applying these insights across a wider range of placements and audience segments to maximize reach and impact. Every decision was driven by data, ensuring that the campaign adapted in real time to changing consumer behaviors.
Not only did 3 Corações recover its lost ground, but it achieved its highest-ever ROAS, soaring to 17—far surpassing its previous peak. Revenue surged by 50% month over month, proving that a well-timed and well-placed brand presence could outshine even the most aggressive keyword-driven campaigns.
