How an Industrial Water Treatment Brand Improved ROAS 94% with DSP

This global manufacturer specializes in industrial water treatment systems, serving commercial and municipal customers with complex filtration and desalination solutions. Operating in a highly technical, high-consideration category, performance depends on reaching qualified buyers with strong purchase intent.

The Challenge

The issue wasn’t performance—it was misalignment.

At launch, DSP was expected to drive both growth and efficiency. But the structure blended customer acquisition and remarketing into a single strategy, diluting performance.

Upper-funnel investment introduced new audiences, but those audiences were not yet converting efficiently. At the same time, DSP campaigns were not aligned with Sponsored Products or promotional activity, weakening overall conversion signals.

The result was predictable: efficiency fell below target, and scaling became difficult to justify.

The account didn’t need more activity. It needed clearer priorities.

Why Quartile

Quartile identified that the challenge was not demand—it was conflicting objectives.

Trying to scale awareness while maintaining strict efficiency targets created tension within the system. Without strong conversion signals, acquisition efforts suppressed overall performance.

Quartile shifted the approach by prioritizing efficiency first. By aligning DSP with high-intent audiences and promotional activity, the strategy focused on strengthening conversion signals before expanding reach.

This created a foundation where performance could improve—and scale could follow.

The Solution

Quartile restructured DSP around a single objective: conversion efficiency.

Customer acquisition campaigns were paused, removing upper-funnel spend that was diluting performance. Budget was consolidated into remarketing campaigns targeting high-intent audiences.

At the same time, DSP was aligned with Sponsored Products through a shared focus on discounted, high-priority SKUs. This ensured that traffic, pricing, and intent were working together.

Instead of introducing new demand, DSP reinforced existing demand—capturing users who had already engaged and converting them more efficiently.

This created a coordinated system:

• Sponsored Products captured high-intent search demand  

• Promotions increased conversion likelihood  

• DSP remarketing reinforced and closed the loop  

By concentrating signals and aligning channels, the strategy improved both efficiency and scalability.

Results & Impact

The impact was immediate and measurable:

• ROAS improved by 94%, exceeding performance targets  

• Revenue increased by 149%, driven by stronger conversion alignment  

These results demonstrate that when DSP is aligned with intent and promotion, it becomes a powerful conversion driver—not just an awareness tool.

Ongoing Value & Future State

With a clear, efficiency-first DSP structure in place, the brand is now positioned to scale with confidence. Future expansion into acquisition can be layered on top of a stable, high-performing foundation.

Quartile continues to optimize audience strategy and cross-channel alignment, ensuring sustained performance as investment grows.
