Why 82% of Brands Are Shifting to Google Display Ads for Omnichannel Dominance
The retail media landscape is undergoing a seismic shift, fueled by the rapid growth of e-commerce and the increasing demand for personalized advertising. According to a Google and Ipsos study, 82% of European consumers now perceive the world as increasingly uncertain, demanding both stability and innovation from retailers. With the European retail media market projected to reach €25 billion by 2026—up from €10 billion in 2022—brands and retailers are racing to capitalize on this lucrative opportunity. At the heart of this transformation is omnichannel marketing, which ensures a seamless shopping experience across online and offline touchpoints. Google Display Ads have emerged as a critical enabler of this strategy, bridging the gap between digital and physical retail environments.
Retail media offers a win-win scenario: retailers monetize their first-party data while brands gain access to highly targeted audiences. However, the genuine potential resides in integrating retail media with omnichannel strategies. Consumers today expect a frictionless journey—whether they’re browsing online, engaging with social media, or walking into a store. Google Display Ads, powered by AI and real-time data, allow advertisers to deliver consistent messaging across multiple platforms, ensuring relevance at every stage of the customer journey. As retail media evolves from a niche tactic to a marketing mainstay, Google Display Network(GDN)’s ability to drive both brand awareness and conversions makes it indispensable for omnichannel success.
I. The Evolution of Retail Media Campaigns
The shift from traditional Dynamic Search Ads (DSA) to AI-powered Performance Max (PMax) campaigns marks a turning point in retail media. While DSAs were effective in automating keyword selection for Google Search, PMax takes automation a step further by optimizing ad placements across all Google channels—Search, Display, YouTube, Gmail, and Discover. A prime example is Ex Libris, Switzerland’s leading online bookseller, which transitioned from DSA to PMax to enhance cross-channel efficiency. Through the use of AI-driven automation, Ex Libris achieved an 8% reduction in its cost per acquisition (CPA) and improved its return on ad spend (ROAS).
PMax’s advantages extend beyond automation. Its multi-channel reach ensures that brands engage consumers at every touchpoint, whether they’re watching YouTube videos or browsing display networks. Additionally, PMax dynamically adjusts creatives and bids based on real-time performance data, maximizing campaign effectiveness. For retailers, this means higher efficiency and scalability—key factors in today’s competitive market. As Ex Libris demonstrated, embracing AI-powered solutions like PMax not only boosts performance but also frees up marketing teams to focus on strategic initiatives rather than manual optimizations.
II. Data-Driven Retail Media Strategies
First-party data is the backbone of successful retail media campaigns, enabling precise targeting and AI-driven optimizations. MediaMarktSaturn (MMS), Europe’s top consumer electronics retailer, exemplifies this approach. By integrating its Customer Data Platform (CDP) with Google Cloud and AI, MMS created a centralized system called PIPA (Product Insights & Performance Automation). This platform analyzes internal and external data—including profitability metrics, inventory levels, and competitor pricing—to predict purchase probabilities and optimize Google ads Shopping and Display campaigns. The results were staggering: a 22% increase in ROAS and a 21% reduction in cost per click.
For brands seeking similar efficiency, solutions like Topkee’s TAG audience segmentation tool can enhance targeting. By analyzing user behavior and interaction data, TAG divides audiences into granular segments, enabling personalized ad experiences that maximize ROI. Meanwhile, Topkee’s TTO platform streamlines campaign management, automating tasks from account setup to conversion tracking, ensuring seamless data integration akin to Google’s Ads Data Manager.
The power of real-time data analytics cannot be overstated. Retailers like Rewe have further enhanced their strategies by using AI to model first-party audiences, allowing brands to target high-intent shoppers across platforms. Google’s tools, such as Ads Data Manager and Enhanced Conversions for Leads, simplify data integration, ensuring that offline conversions are accurately tracked. For marketers, this means better personalization, higher ROI, and the ability to adapt campaigns dynamically. As retail media matures, those who harness first-party data with AI will gain a decisive competitive edge.
Tools like Topkee’s TM tracking links provide deeper insights than standard UTMs, allowing advertisers to monitor creative performance across themes, sources, and media. Combined with AI-driven creative optimization—such as Topkee’s AI-generated ad copy and visuals—brands can dynamically adapt campaigns to shifting consumer behavior.
As retail media evolves, leveraging first-party data with advanced tools—whether through retailer CDPs or solutions like Topkee’s Weber landing page builder—will separate leaders from competitors. The key lies in unifying data, automation, and cross-channel measurement to drive both immediate conversions and long-term growth.
III. Google Display Ads as an Omnichannel Enabler
Google Display Ads serve as a powerful extension of retail media, bridging the gap between onsite and offsite advertising. While onsite placements (e.g., within e-commerce platforms or apps) are constrained by limited inventory, offsite campaigns powered by first-party data unlock expansive reach across the web. Leading retailers like OBI and Rewe have demonstrated the effectiveness of this approach, leveraging Google Display Network(GDN) to engage audiences beyond their owned channels. Notably, MediaMarktSaturn (MMS) reported a 2.5x higher omnichannel ROAS compared to online-only campaigns, underscoring GDN’s ability to drive both digital and in-store conversions.
However, retail media’s potential extends beyond lower-funnel performance. A critical challenge lies in upper-funnel brand building, with 50% of brands citing a lack of standardized KPIs for measuring awareness campaigns. To address this, retailers must align metrics with broader brand objectives—prioritizing not just clicks and conversions but also revenue growth and brand lift. AI-driven audience modeling, exemplified by Douglas’s Customer Data Platform (CDP), enables precise identification of high-value customers and delivery of personalized messaging.
For instance, tools like Topkee’s TAG system analyze user behavior to segment audiences and optimize ad targeting, while TTO streamlines account management and performance tracking. By integrating such solutions, retailers can enhance both onsite and offsite strategies, creating a seamless omnichannel experience that balances immediate sales with long-term brand equity.
This holistic approach is further amplified by advanced creative optimization. Topkee’s AI-powered creative tools, for example, accelerate ad iteration by generating tailored text, images, and videos aligned with campaign themes. Coupled with TM tracking links, advertisers gain granular insights into creative performance, enabling rapid adjustments. Together, these capabilities ensure Google Display Ads not only maximize reach but also deliver consistent, high-impact messaging across every customer touchpoint.
IV. Future Trends and Strategic Recommendations
The retail media market is poised for exponential growth, but standardization and AI-driven measurement tools will be critical. Advanced solutions like Google ads’s Meridian (an open-source marketing mix modeling tool) and incrementality testing help advertisers allocate budgets more effectively, ensuring optimal ROI across channels. Meanwhile, AI will continue to refine targeting, with innovations like PMax for Store Goals enhancing brick-and-mortar conversions.
For retailers and brands, the path forward is clear: invest in first-party data, integrate AI-powered tools, and adopt a unified measurement framework. Retail media is no longer optional—it’s a necessity for staying competitive in an omnichannel world. By leveraging Google Display Ads and AI-driven automation, businesses can unlock new growth opportunities while delivering seamless, personalized customer experiences.
Conclusion
Retail media is revolutionizing the advertising landscape, and Google Display Ads are at the forefront of this transformation. From AI-powered PMax campaigns to data-driven personalization, enables brands to connect with consumers across every touchpoint. As the industry evolves, retailers must prioritize first-party data, advanced measurement, and cross-channel integration to maximize their impact.
