The Retail Media Evolution: Navigating In-Store, Grocery, and Travel Ecosystems

This post was created in partnership with SMG

As the digital advertising landscape faces the sunset of third-party cookies and a shift toward first-party data, the rise of retail media networks (RMNs) has evolved from a burgeoning trend into the backbone of modern marketing. Retail media is no longer confined to sponsored search results on e-commerce sites; it has expanded into a sophisticated, omnichannel ecosystem that bridges the gap between digital intent and physical reality.

During the recent ADWEEK House Advertising HQ, a series of commerce connection sessions—co-hosted with SMG—brought together industry leaders to dissect the rapidly shifting landscape. From the complexities of measuring in-store media effectiveness to the nuances of reaching grocery shoppers and the untapped potential of travel media networks, these sessions provided a roadmap for how brands can thrive in an era where every physical and digital touchpoint is a potential point of sale.

The In-Store Renaissance: Strategies for Physical Retail Leadership

The opening session, titled "Choose Your Player: The Battle for In-Store Leadership," served as a wake-up call for brands that have leaned too heavily into digital-only strategies. Moderated by Ollie Shayer, senior director of global strategy and innovation at SMG, the panel featured a powerhouse lineup: Collin Colburn (VP of commerce and retail media, IAB), Chip Harding (EVP of Simon Media and Experiences, Simon Property Group), Austin Leonard (VP and GM, DG Media Network), and Britt Polihronis (COO of RedMedia at Hy-Vee, Inc.).

Bridging the Gap Between Foot Traffic and Conversion

The central thesis of the discussion was that the "in-store experience" is being fundamentally reimagined through data. For years, the physical store was viewed as a black box where attribution went to die. Today, retailers are deploying advanced sensor technology, loyalty program integration, and digital signage to turn the physical aisle into a measurable media channel.

However, the panel noted that "success" looks different depending on the venue. For Simon Property Group, which manages vast shopping centers, success is defined by foot traffic, dwell time, and the conversion of physical presence into retail spend. Conversely, for grocery giants like Hy-Vee and Dollar General, the metrics are more granular: immediate, high-frequency product pickup and basket-size expansion.

The Measurement Mandate

The industry’s collective obsession with "incremental sales" was at the forefront of the debate. Advertisers are no longer satisfied with vanity metrics; they are demanding proof that their investment in in-store media actually drove a purchase that wouldn’t have occurred otherwise. The panelists emphasized that while measurement is the ultimate goal, it must be balanced with the "consumer experience."

"If we over-saturate the physical environment with ads, we lose the magic of discovery," noted one panelist. The challenge, therefore, lies in curating brand offerings that feel native to the shopping environment—turning a static shelf into a platform for product trials and experiential marketing that adds value to the shopper’s journey rather than interrupting it.

Grocery Media: Mastering the Full-Funnel Journey

In a high-impact fireside chat, "From Story to Store: Creating Connected Campaigns Across Every Touchpoint," Zoë Ruderman, chief content officer at ADWEEK, engaged Liz Roche, VP of media and measurement at Albertsons Media Collective, in a deep dive into the unique challenges of the grocery sector.

Beyond the Point of Sale

Grocery is perhaps the most personal vertical in retail. It is a recurring, high-frequency ritual that anchors a consumer’s week. Because it is so ingrained in daily life, Roche argued that brands must stop viewing grocery media as a "bottom-of-the-funnel" tactic.

"If you are only showing up when the shopper is at the shelf, you’ve already lost the battle for brand preference," Roche explained. She advocated for a broader "connected" strategy that utilizes Connected TV (CTV) to build brand awareness long before the shopper enters the store. By syncing digital video ads with in-store promotions, retailers can create a cohesive narrative that guides the consumer from the living room to the checkout line.

The Metrics Reckoning

Perhaps the most provocative portion of the discussion was Roche’s critique of standard retail media metrics. She openly challenged the industry’s reliance on Return on Ad Spend (ROAS) and Incremental ROAS (iROAS).

"These metrics are highly volatile," Roche noted. "They shift wildly depending on whether you use a last-click model, a weighted model, or a full-funnel attribution model." Instead of chasing a single, flawed metric, Roche urged marketers to adopt a more "critical thinking" approach. This involves looking at the aggregate health of a category: how did the campaign affect total unit movement? How did it impact brand equity? By shifting the focus from narrow attribution to holistic performance, brands can gain a more accurate, albeit nuanced, understanding of their return on investment.

The New Frontier: Why Travel Media is Taking Off

The final segment of the event, "Media on the Move: How Brands Are Winning Across the Travel Journey," shifted the focus to an emerging powerhouse in the RMN space. Moderated by Sean Crawford of SMG, the panel included experts from across the travel spectrum: Katie Blackburn (WHSmith North America), Shane Dwyer (Lyft Ads), Chris Norton (Marriott Media), and Steven Paganelli (Tripadvisor).

Why Travelers Are the Ultimate High-Value Audience

The panel identified a compelling demographic truth: travelers are essentially "high-intent" consumers. When people travel, they are often in a state of elevated spending—whether for home improvement (to prepare the house for an absence), alcohol (for events), or premium retail products.

Furthermore, the "travel mindset" creates a unique psychological opening. Consumers on vacation or on a business trip are often more receptive to brand messaging because they are in a state of discovery. They are actively seeking new experiences, which makes them prime targets for brand trials and partnerships.

A Journey-Based Measurement Approach

Because travel is non-linear—spanning from the initial booking phase to the transit phase, the stay phase, and the post-trip reflection—traditional retail measurement is insufficient. The panelists argued that advertisers need to map their media against the "highs and lows" of the journey.

• The Planning Phase: Capturing intent through search and content platforms like Tripadvisor.
• The Transit Phase: Utilizing the captive audience environment of ride-shares (Lyft) and airport retail (WHSmith).
• The Experience Phase: Leveraging the hotel environment (Marriott) to deliver personalized, relevant offers.

The key takeaway was that travel media networks are not just about booking flights or hotels; they are about capturing a specific, lucrative, and temporary state of mind.

Implications for the Future of Retail Media

As these three sessions illustrated, the retail media landscape is maturing. The "Wild West" days of early adoption are being replaced by a more disciplined, data-driven, and highly integrated approach.

1. The Consolidation of Data

The most successful networks are moving away from silos. Whether it is a grocer using CTV data or a travel brand using loyalty insights, the common denominator is the unification of first-party data. Brands that fail to integrate their digital and physical datasets will find themselves at a severe disadvantage.

2. The Shift to "Holistic" Measurement

The industry is moving toward a post-ROAS era. While conversion metrics will always be important, the conversation is shifting toward "long-term value." The leaders in this space are those who can prove that their media spend is driving category growth and brand loyalty, not just short-term sales spikes.

3. The Power of "Captive" Environments

Retail media is expanding into environments where consumers are naturally engaged. From the aisles of a supermarket to the back seat of a Lyft or the lobby of a hotel, brands are finding that the best way to reach a consumer is to meet them where they are already spending their time and money.

Final Thoughts

The retail media networks of tomorrow will be defined by their ability to provide a seamless, value-added experience for the consumer. As brands navigate this evolving terrain, the successful ones will be those that treat retail media not as a transactional line item, but as a core component of their overall business strategy. By focusing on the full consumer journey—from the initial spark of interest to the final, physical point of purchase—brands can unlock unprecedented opportunities in a world where commerce is everywhere.
