ROAS

Summary of case study

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.

Solution

For years, paid search had been the dominant driver of digital success for 3 Corações, a proven strategy that had reliably delivered strong returns. But when ROAS unexpectedly plummeted, it became clear that the landscape had shifted beneath them. Competitors had found ways to sidestep traditional search methods, reaching customers before they even typed a query into the search bar.

Consumers were no longer looking for coffee in the ways they once did—they were absorbing content, engaging with recommendations, and making split-second decisions based on what they saw in their digital environment. Simply increasing bids and refining keywords would no longer be enough.

If 3 Corações wanted to win, it had to appear where customers were already looking—not just where they were searching. The Strategy: With the playing field fundamentally altered, the brand needed to evolve. The breakthrough moment came in recognizing that purchase decisions were happening before search—within the digital content consumers engaged with daily.

This called for a radical departure from traditional paid search campaigns. The answer lay in contextual advertising, powered by AI and Amazon’s proprietary data. Instead of waiting for consumers to search for coffee, 3 Corações placed its brand messaging within highly relevant content—product pages, reviews, and even competitor listings—where interest in coffee was already brewing.

The campaign leveraged real-time behavioral data to determine the perfect moments to serve ads, ensuring that the brand felt less like an interruption and more like a natural part of the shopping experience. By deeply integrating with Amazon’s AI-driven advertising capabilities, we tailored placements dynamically, allowing the campaign to adapt in real time.

No longer were ads static or predictable; they evolved with consumer behavior, appearing precisely when and where they had the greatest likelihood of success. 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. The Results: The result was nothing short of extraordinary.

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. 3 Corações had successfully adapted to a new digital landscape—one where search behavior was no longer the kingmaker. Instead, consumer context and engagement dictated success, and by recognizing and acting on that shift, the brand achieved results that exceeded even its most ambitious expectations.

“Brainlabs played a crucial role in our strategic approach to the digital market. During the initial structuring phase, their understanding of the platform and their agility were essential to the success of our campaigns and the significant sales results. The team was always committed to delivering the best possible outcomes, consistently recommending the most effective strategies and making adjustments to our course with great efficiency, both in day-to-day operations and during major sales periods.”
