+91% ROAS by Unifying 4 Channels Into One Performance Engine

Full-funnel multi-channel performance campaign dashboard with display, social, native, and video metrics

The Challenge: Siloed Channels, Invisible ROI

A direct-to-consumer skincare brand had grown rapidly through organic social but was hitting a ceiling. Their paid media efforts were completely siloed -- display ran independently from social, video was treated as pure awareness with no connection to performance goals, and nobody could answer the basic question: which channel actually drives conversions? The result was fragmented data, duplicated reach, and a CPA that climbed every month.

We unified the brand's paid media into a cohesive full-funnel architecture spanning display, social, native, and video programmatic -- managed across DV360 for display and video, and Amazon DSP for the brand's marketplace traffic. We implemented cross-channel frequency management, data-driven attribution replacing last-click, and an algorithmic budget allocation engine that moved spend hourly to the highest-performing channel-audience combinations. The result: +91% ROAS and -31% blended CPA over 16 weeks, with every channel measured by its true contribution using CPA and CPC pricing models.

How We Delivered It

A unified performance engine across DV360 and Amazon DSP that orchestrates every channel toward a single CPA goal with real-time budget fluidity.

Full-funnel channel architecture

We mapped each channel to its optimal funnel role -- video on DV360 for awareness, native for consideration, display for CPC-based retargeting, social for both prospecting and conversion, and Amazon DSP for marketplace intent capture. One unified journey from first touchpoint to purchase.

Cross-channel frequency management

We deployed a unified frequency cap across all channels and DSPs, eliminating the ad fatigue that comes from each platform independently bombarding the same user. This alone reduced wasted impressions by over 35% and lowered blended CPC across the board.

Algorithmic budget allocation

We built a budget optimization model that shifted spend between channels hourly based on marginal ROAS. DV360 video overspending on a Thursday afternoon? Budget automatically moved to native or Amazon DSP where conversion rates were peaking. No manual intervention required.

Data-driven cross-channel attribution

We replaced the brand's last-click model with data-driven attribution that credited every touchpoint fairly across channels. This revealed that upper-funnel video on DV360 was driving 3x more assisted conversions than last-click had shown -- justifying continued investment.

Why Kalithea Made the Difference

No channel silos, no hidden agendas

As an independent agency, we have no incentive to push one DSP over another. Every decision -- from creative production to bid strategy on DV360 vs. Amazon DSP -- was made with full visibility into cross-channel interactions, ensuring each investment amplified the others.

Real-time budget fluidity across DSPs

Our algorithmic allocation engine moved budget to the highest-performing channel-audience combinations hourly across DV360 and Amazon DSP, capturing emerging opportunities that fixed-budget or single-platform approaches miss entirely.

Transparent reporting with verified quality

We maintained strict quality standards across every channel -- 92% average viewability, verified brand-safe environments, and human-only traffic. Every CPA, CPC, and CPM was reported transparently with no hidden margins or inflated metrics.
