Are You Leveraging Enhanced Conversions for Google Display Ads?
The digital marketing landscape is undergoing a seismic shift as privacy regulations tighten and consumer awareness grows. In 2025, brands like Sky face a dual challenge: delivering personalized ads while respecting user privacy. With cookie deprecation and stringent consent barriers, marketers are losing critical data points that once fueled targeted campaigns—especially for Google Display Ads , where audience reach relies heavily on third-party signals. Google’s recent updates, such as enhanced ad relevance algorithms for Search, GDN, and YouTube, highlight the industry’s pivot toward privacy-centric solutions. Sky’s innovative use of Enhanced Conversions—a hashed-email technology—demonstrates how brands can bridge this gap for Google Display Ads and beyond. By recovering 12% of lost Search conversions and 21% of YouTube conversions, Sky proves that privacy and performance need not be mutually exclusive, even in GDN campaigns. This case study explores how Sky turned regulatory constraints into a competitive advantage.
I. Sky’s Marketing Landscape and Data Gaps
Sky operates in Germany’s volatile Pay-TV market, where streaming platforms and shifting consumer behaviors demand agile marketing. As VP Digital Channels Norbert Pellkofer notes, the line between customers and non-customers has blurred, making audience segmentation increasingly complex. Traditional cookies, once the backbone of performance marketing for GDN, now fail to capture cross-device journeys due to shortened lifespans and low consent rates (as low as 10% for Google Display Ads). These gaps distort attribution, forcing Sky to either overspend on upper-funnel ads or risk missing conversion opportunities. For instance, without consent, retargeting users who abandoned carts became nearly impossible. Sky’s solution? Leverage first-party data through Enhanced Conversions, which hashes emails to anonymize identities while preserving GDN campaign measurability.
II. Enhanced Conversions as a Privacy-Centric Solution
Enhanced Conversions represent a transformative approach to digital advertising by leveraging first-party data—such as emails collected during checkout—which is then hashed into anonymized strings and matched to ad interactions, including Google Display Ads . This methodology effectively reduces reliance on third-party cookies while ensuring compliance with stringent privacy regulations like GDPR.
Topkee’s expertise in Google Display Ads aligns seamlessly with the principles of Enhanced Conversions. The company’s solutions focus on optimizing multimedia advertising campaigns to reach over 90% of global internet users, ensuring precise audience targeting and improved conversion rates. By integrating Enhanced Conversions, Topkee enhances its ability to track and attribute conversions accurately. This is particularly valuable for GDN campaigns, where retargeting and performance measurement are essential for maximizing ROI.
This is further reinforced by Topkee’s use of advanced tools like TAG for audience segmentation and TTO for streamlined ad management, which complement Enhanced Conversions by providing granular insights into user behavior and campaign performance. For instance, Topkee’s approach to Google Display Ads includes dynamic creative optimization and AI-driven ad material generation, enabling continuous A/B testing to identify high-performing creatives—a strategy that benefits significantly from the additional conversion data provided by Enhanced Conversions.
Moreover, Topkee’s emphasis on landing page optimization and TM tracking links ensures that ads and post-click experiences are tightly integrated, improving conversion rates while maintaining privacy compliance. The company’s periodic performance reporting and delivery analysis further leverage Enhanced Conversions data to refine budgeting, CTR optimization, and cost-per-acquisition strategies. By adopting Enhanced Conversions, Topkee not only enhances the precision of its Google Display Ads campaigns but also future-proofs its advertising strategies against evolving privacy regulations.
Pellkofer’s observation that Enhanced Conversions require no additional tools like a CDP resonates with Topkee’s operational philosophy, which prioritizes cost-efficiency and scalability. The technology’s ability to recover lost conversions—such as the 12% uplift in Search Ads and 21% improvement in YouTube Ads noted in Sky’s case—demonstrates its potential to deliver measurable results for GDN and other channels. For Topkee, this translates into stronger campaign performance, higher click-through rates, and more efficient budget allocation, all while upholding the highest standards of user privacy and data protection.
III. Implementation and Privacy Compliance
Sky’s rollout involved close collaboration with Google and GroupM to address technical and legal hurdles for Google Display Ads and other platforms. Key steps included:
1. Real-Time Hashing: Implementing pixel-based hashing to anonymize data before transmission.
2. Consent Management: Adopting a conservative opt-in approach, ensuring no data transfer without explicit user approval.
3. Third-Party Audits: Conducting workshops with Google to validate data handling practices, including server locations and encryption.
Pellkofer notes that early involvement of legal and IT teams was critical to avoid delays. The result? A system that met both marketing and compliance goals.
IV. Measurable Outcomes and Strategic Advantages
Beyond recovering lost conversions, Enhanced Conversions provided Sky with unprecedented cross-channel visibility—particularly into the performance of the Google Display Network (GDN). For instance, the data revealed distinct user behaviors: sports enthusiasts frequently converted after engaging with YouTube ads, while price-sensitive audiences responded more to Search campaigns or Google Display Ads. This granular insight enabled Sky to dynamically reallocate budgets toward high-performing channels, maximizing ROI. Norbert Pellkofer, VP Digital Channels at Sky, emphasized that this precision transformed their media strategy, allowing them to reduce inefficiencies and capitalize on micro-moments in the customer journey.
Sky achieved a 15% reduction in wasted ad spend on the Google Display Network by leveraging Enhanced Conversions’ refined targeting capabilities. Previously, limited data made it challenging to distinguish between high-intent users and passive viewers. With hashed email data, Sky could attribute conversions more accurately, eliminating overlap with other channels like YouTube. This not only improved cost efficiency but also minimized ad fatigue—ensuring users saw fewer repetitive ads. Pellkofer noted that this optimization was critical for upper-funnel campaigns, where consent rates are typically lower and visibility into user paths is fragmented.
While Enhanced Conversions didn’t directly increase total sales, its data accuracy enabled Sky to reduce ad duplication and refine audience segmentation across GDN, YouTube, and Search. For example, users exposed to YouTube ads were excluded from redundant GDN retargeting, improving user experience. Pellkofer highlighted that these efficiencies are foundational for adapting to a cookieless future, where first-party data and privacy-compliant tools will dominate. Sky’s success underscores the importance of integrating such technologies early to maintain competitive agility.
V. Lessons for the Industry
Sky’s success offers actionable insights for Google Display Ads and broader digital marketing:
1. Stakeholder Alignment: Involve legal, IT, and marketing teams from day one to streamline compliance.
2. First-Party Data: Prioritize owned data streams (e.g., login emails) to future-proof against cookie deprecation.
3.Test Early: Pilot privacy tech like AI-driven aggregated analytics to balance personalization and anonymity.
VI. Future of Privacy-Centric Advertising
As Pellkofer predicts, the future lies in anonymized, aggregated data models—especially for Google Display Ads. AI will play a pivotal role in extracting insights without compromising individual identities in GDN campaigns. Sky’s journey underscores that privacy compliance isn’t a barrier—it’s a catalyst for innovation in Google Display Ads and beyond.
