A SEARCH ADVERTISING WORK

Plaisio, one of Greece’s most prominent consumer electronics retailers, partnered with MEDIACUBE to transform its approach to Google Search campaigns. Already experienced in performance marketing, Plaisio sought a future-ready strategy that would break free from the constraints of traditional search ads and harness the full potential of AI, machine learning and privacy-centric measurement.

Through a radical rebuild of their search framework, driven by automation, CDP (Customer Data Platform) integration and strategic bidding, the result was a fully optimized, next-gen search advertising model that not only delivered impressive results but also set a new benchmark for efficiency, accuracy and digital innovation.

THE CHALLENGE

In a year marked by global uncertainty, inflationary pressure, supply chain disruptions and shifting consumer behaviors, Plaisio recognized the need for a bold shift in its digital strategy. The key challenge: maximize the performance of Google Search Ads campaigns while minimizing wasted ad spend; a vision defined as “zero waste of advertising budget”.

Data blindness

Due to evolving cookie policies and restrictive privacy settings, traditional optimization models lost clarity.

Attribution disruption

With Google’s data-driven attribution now spanning all campaign types (search, video, display, etc.), isolating and optimizing Search campaigns became more difficult.

Manual limitations

Old-school keyword targeting and bidding strategies were no longer sufficient for a market shaped by AI and automation.

Plaisio needed a radical overhaul—one that embraced innovation, ensured data privacy and unlocked the full potential of modern search marketing.

THE SOLUTION

MEDIACUBE designed and implemented a modern, AI-powered search campaign architecture grounded in automation, predictive analytics and privacy-first principles. The core pillars of the solution included:
AI-powered campaign design

Migration to dynamic search campaigns combining both keyword ad groups (using broad match with margin-based ROAS targets) and dynamic ad groups with URL and tag-based targeting. AI-powered responsive text ads and A/B testing tools were deployed for real-time creative optimization.

Smart bidding and margin-based targeting

Customized bidding strategies were introduced based on product margins. Unified ROAS targets helped optimize profitability at the category level, moving beyond per-keyword optimization.

Auto-apply recommendations (AAR)

Automation was leveraged to handle tactical adjustments, freeing time for strategic planning and reducing human error.

Privacy-centric measurement

MEDIACUBE implemented full PCM (Privacy-Centric Measurement) via Google’s Consent Mode 2.0, enhanced conversions and global tagging. Customer data was unified within Plaisio’s CDP, enabling the creation of behavioral segments and conversion signals.

Data-driven decisioning

AI-driven scripts and dashboards identified high-performing search windows, trends in CTRs, CPCs and conversion rates. These insights directly informed campaign adjustments and creative updates.

This integrated, privacy-compliant and insight-rich approach empowered Google’s smart bidding models to deliver optimal performance at scale, even in a constrained data environment.

THE RESULTS

The results of the “AI Era of Smart Search Ads” strategy speak for themselves. Compared to the same period in the previous year (Dec 2024 – Apr 2025), Plaisio’s reimagined Google Search campaigns delivered significant performance gains:
