Retail media networks (RMNs) are on the brink of a major shift. While they are poised to capture over 20% of ad spend in 2025, on-site monetization won’t be the growth driver it once was. With advertisers consolidating spend among just six or seven RMNs on average, including giants like Amazon and Walmart, it’s hard for smaller RMNs to compete.
Off-site retail media ad spend is projected to grow 42.1% in 2025 – nearly three times the rate of on-site growth (15.1%), according to eMarketer’s November 2024 forecast. This dramatic shift underscores that while on-site placements are maturing, off-site is where the momentum (and money) is heading.
To remain competitive, RMNs must move beyond traditional, on-site placements and embrace a broader, more integrated approach to media activation. The future of retail media is about utilizing enriched first-party data to drive performance across the open web, connected TV (CTV), and other digital channels.
Break free from your owned and operated properties
Historically, RMNs have limited ad placements to their own digital properties. While this approach has delivered high-margin returns – on-site ad margins can reach 70-90%, compared to 20-40% for off-site – it’s also inherently limiting. Retailers only have so much owned inventory to sell, and advertisers demand greater scale and flexibility. As brands push for more reach, RMNs must extend their impact beyond owned-and-operated (O&O) properties.
Omnichannel retail media ad spending is forecast to hit $61.2 billion in 2025. Brands are looking beyond retail sites to build integrated, multi-channel strategies that drive results across the funnel.

Off-site doesn’t just mean digital. Walmart’s recent expansion of its Fuel and Convenience stations – planning to open or remodel 45 in 2025, bringing the total to 450 – shows how physical spaces are also becoming extensions of a retailer’s media network. These locations create new touchpoints where advertisers can engage shoppers with timely, context-aware messaging while they fuel up or grab a snack.
These quick-stop environments are ideal for limited-time offers or impulse-triggering messages – especially since 68% of U.S. adults say discounts contribute to their latest in-store impulse purchase.
Maximize the value of first-party data
One of retail media’s biggest promises is the power of first-party data for precision targeting. While on-site ads are inherently lower-funnel, off-site activation allows advertisers to move up the funnel and apply retailer customer data holistically across the open web.
For example, DoorDash and Macy’s now offer self-service audience data to advertisers via The Trade Desk, allowing brands to target consumers programmatically. Meanwhile, Walmart is taking a different approach – cloning The Trade Desk’s technology to maintain its walled garden. These moves demonstrate how retailers are rethinking data monetization strategies to scale beyond O&O limitations.
Drive new revenue streams with off-site activation
Off-site activation enables RMNs to drive incremental reach on channels where audiences are actively engaging, including CTV, programmatic display, and social media. This expansion allows brands to connect with consumers beyond retail websites.
Retailers are also utilizing non-endemic advertising opportunities in environments like gas stations and kiosks. Unlike traditional grocery or apparel aisles, these spaces are brand-neutral, allowing advertisers who don’t sell products in-store to still activate campaigns using retailer data. In fact, 53% of brands have already partnered with a retailer that doesn’t carry their product, and that number is expected to grow as advertisers seek new ways to tap into retail media’s rich targeting capabilities.
Retailers looking to extend the value of their data beyond O&O inventory have two primary off-site opportunities:
First, they can use an identity graph to resolve customer identifiers into addressable IDs that can be enriched with additional attributes and activated across channels like the open web and CTV. This allows retailers to find and reach known customers with relevant messaging outside of their owned platforms. For example, a grocery RMN can identify lapsed snack buyers and deliver streaming TV ads that reengage them on CTV platforms. CTV retail media ad spending alone is expected to grow 43.1% this year, reaching $4.86 billion, highlighting the appetite for video-based upper-funnel strategies.
Second, RMNs can broaden reach by activating first-party audiences, syndicated segments, or custom-built audiences through onboarding capabilities. These audiences can be sent to a variety of programmatic and CTV destinations, enabling advertisers to engage shoppers in high-impact environments. For example, a home improvement retailer can send its audience segments to programmatic ad exchanges, ensuring DIY shoppers see relevant offers even while browsing unrelated sites.
Together, these approaches allow retailers to monetize their data more effectively while giving brands the ability to reach consumers in moments that matter beyond just retail websites and apps.
Scale and measure success with data partnerships
For smaller RMNs to compete with larger players, they need more than just inventory – they need the ability to scale campaigns and prove performance. Data partnerships play a critical role in both expansion and measurement.
Measurement remains one of the biggest challenges for RMNs moving off-site. On-site retail media offers closed-loop attribution, but off-site activations introduce complexity. Retailers can work with an identity resolution partner like Experian to connect ad exposures to actual retail outcomes, such as store visits or purchases, across digital and physical environments. Whether it’s through pixels placed on campaign ads or TV impression logs, these connections help RMNs demonstrate real impact.
This approach helps unify disparate data – such as a CTV ad exposure and a subsequent online or in-store purchase – into a clear, measurable outcome. These insights not only show what’s working, but help RMNs optimize future campaigns and provide advertisers with transparent, third-party-validated reporting.
As retailers like Walmart integrate loyalty programs like Walmart+ into their physical extensions, they gain valuable behavioral insights into how customers shop across formats – from fueling up to filling carts. These data signals help refine identity graphs and improve measurement across increasingly hybrid consumer journeys.
Beyond ads: The data monetization opportunity
Smaller RMNs may struggle to scale ad-supported revenue, but there’s another path forward: Data-as-a-Service (DaaS). Providing anonymized, privacy-compliant audience insights to brands offers a high-margin, scalable revenue stream. In fact, some retailers are already embracing this model by licensing their data to programmatic platforms.
A playbook for smaller RMNs to win off-site
The future of retail media belongs to those who harness data to influence consumer behavior across all digital marketing channels. To succeed, RMNs should focus on:
- Moving beyond owned inventory: Activate first-party data across CTV, social, and programmatic channels to meet advertisers where their audiences are.
- Expanding reach through partnerships: Collaborate with identity resolution providers to maximize match rates and campaign effectiveness.
- Building a full-funnel offering: Position off-site retail media as a brand-building play, tapping into ad budgets that traditionally fund upper-funnel campaigns.
- Monetizing data, not just ads: Explore DaaS models to generate passive revenue.
The time to move off-site is now
Retailers that wait too long to embrace off-site activation risk falling behind. Those that expand beyond their owned inventory, invest in off-site data strategies, and build strategic partnerships will be the ones that shape the future of retail media.

In our last few blog posts, we’ve talked about customer segmentation and different ways to segment your target audience into smaller chunks like demographic and psychographic segmentation to connect with the right people. Customer segmentation enables marketers to focus their marketing efforts on their target customers, improving their marketing targeting strategy. But what if there was a subset of users that had an even bigger impact when targeted? Enter Super Users – the strategic players who can give your ROI numbers a major boost! It may take some trial-and-error testing to pinpoint these super segments accurately, but knowing how these key individuals interact is essential for any successful marketing targeting strategy. What is a Super User? As technology progresses and media consumption grows, a unique group is rising to the top. Activate Consulting's Technology & Media Outlook 2023 found that Super Users are powering the digital world, with a strong presence across all major media and technology verticals. This select crowd is made up of young, educated individuals who lead affluent lifestyles – spending more time and money than any other user group! Why should you add Super Users to your marketing targeting strategy? Super Users are a highly influential audience with the potential to drive major business growth. They stand out from other users in their commitment and dedication across four key areas: Time spent with media Spend Technology and media adoption Emerging eCommerce behaviors “Over the next years, the imperative for technology and media companies will be to identify, reach, and super-serve Super Users – the single group of power users whose time and spend far surpass those of other users.”Activate consulting's technology & media outlook 2023 You can use Super Users as a subset of your marketing targeting strategy. While you may need to reach beyond Super Users to achieve your goals, it’s worthwhile to consider: Targeting them separately Spending more on media Reaching them at a higher frequency Time spent with media Super Users make a powerful impact, despite comprising only 22% of the U.S. population. They are incredibly influential in terms of media consumption and engagement – spending more than double the amount of time interacting with content compared to other users. Inclined to multitask Super Users take multitasking to the next level. Not only do they spend more time with electronics, but they excel in the art of juggling multiple activities. While watching videos and playing video games on one device, Super Users might also be busy engaging with social media on another. This makes them an unstoppable force when it comes to getting the most out of their digital experiences! High share of dollar spend Super Users are big spenders when it comes to media, particularly in gaming and music. Compared with all other users, Super Users' average video spend is close to triple the amount ($76 vs $27). However, their biggest increases come from gaming and music; they're collectively spending 12x more on games and shelling out 21x as much for tunes! With 60% of eCommerce spend coming from Super Users, they are driving the industry forward with their enthusiasm and willingness to test out cutting-edge shopping trends like buying through social media, live streaming purchases, and trying on products virtually. Super Users are setting the tone for this dynamic industry. Technology and media adoption Most Super Users are brand advocates. They’re trendsetting individuals who stay ahead of the curve on media and technology. They eagerly take advantage of new products, services, and data-sharing opportunities to receive tailored ads that fit their lifestyle. Crypto & NFTs Super Users blaze the trail for cryptocurrency and non-fungible tokens (NFTs)! This group is five times more likely to explore, engage with, and embrace new digital-monetary technologies. Pioneers of the Metaverse As Metaverse usage continues to rise, Super Users are leading the way. Over 80% of these trailblazers have embraced these digital spaces within just the last year. We’re seeing accelerated interest from them as they seek out new opportunities for creativity, connections, and transactions within their favorite Metaverses. Many express interest in Metaverse experiences such as purchasing physical items to creating virtual havens. In fact, they’re 5x more interested in all things meta-related!

Note: While third-party cookies are no longer being phased out, this webinar was recorded in 2023 when cookie deprecation was still a key industry focus. The strategies discussed reflect that time frame and remain relevant for addressing broader signal loss challenges. With major browsers discontinuing support for third-party cookies, marketers must rethink how to identify and engage their audiences. Contextual advertising offers a privacy-safe solution by combining contextual signals with machine learning to deliver highly targeted campaigns. In a Q&A with our experts with eMarketer, Jason Andersen, Senior Director of Strategic Initiatives and Partner Solutions at Experian, and Alex Johnston, Principal Product Manager at Yieldmo, we discuss how contextual advertising addresses signal loss, improves addressability, and delivers better outcomes for marketers. The macro trends impacting marketers How important is it for digital marketers to stay informed about the changes coming to third-party cookies, and what challenges do you see signal loss creating? Jason (Experian): Third-party cookies have already been eliminated from Firefox, Safari, and other browsers, while Chrome has held out. It’s just a matter of time before Chrome eliminates them too. Being proactive now by predicting potential impacts will be essential for maintaining growth when the third-party cookie finally disappears. Alex (Yieldmo): Third-party cookie loss is already a reality. As regulations like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) take effect, more than 50% of exchange traffic lacks associated identifiers. This means that marketers have to think differently about how they reach their audiences in an environment with fewer data points available for targeting purposes. It’s no longer something to consider at some point down the line – it’s here now! Also, as third-party cookies become more limited, reaching users online is becoming increasingly complex and competitive. Without access to as much data, the CPMs (cost per thousand impressions) that advertisers must pay are skyrocketing because everyone is trying to bid on those same valuable consumers. It’s essential for businesses desiring success in digital advertising now more than ever before. Solving signal loss with contextual advertising How does contextual advertising help marketers engage audiences with new strategies like machine learning and artificial intelligence (AI)? Jason (Experian): Contextual advertising helps marketers engage audiences by combining advanced machine learning with privacy-safe strategies. We focus on using AI and machine learning to better understand behavior, respect privacy, and deliver insights. As third-party cookies go away, alternative identifiers are coming to market, like Unified I.D. 2.0 (UID2). These are going to be particularly important for marketers to be able to utilize them. As cookie syncing becomes outdated, marketers will have to look for alternative methods to reach their target audiences. It’s essential to look beyond cookie-reliant solutions and use other options available regarding advertising. Alex (Yieldmo): There’s been a renaissance in contextual advertising over the last couple of years. Three key drivers are shaping this shift: The loss of identity signals is forcing marketers to rethink how they reach audiences. Advances in machine learning allow us to analyze more granular contextual signals, identifying patterns that are most valuable to advertisers. Tailored models now use these signals to deliver more effective campaigns. This transformation is occurring because of our ability to capture and operate on richer, more detailed data. Reach consumers with advanced addressability How does advanced contextual advertising help marketers reach non-addressable audiences? Jason (Experian): Advanced contextual advertising helps marketers reach non-addressable audiences by taking a set of known data (identity) and drawing inferences from it with all the other signals we see across the bidstream. It’s about using a small seed set of customers, those who have transacted with you before or match your target audience, and training contextual models to make the unknown known. Now we can go out and find users surfing on any of the other sites that traditionally don’t have that identifier for that user or don’t at that moment in time and start to be able to advertise to them based on the contextually indexed data. Alex (Yieldmo): I think the exciting opportunity for many people in the industry is figuring out how to reach your known audience in a non-addressable space, that is based on environmental and non-identity based signals, that helps your campaign perform. Machine learning advancements allow you to take your small sample audience and uncover those patterns in the non-addressable space. High-quality, privacy-resilient data sets are critical for building these campaigns. Companies like Experian, with deep, rich training data, are well positioned to support advertisers in building extension audiences. Creative strategies that improve ad performance Why does creative strategy remain essential for digital advertising success? Jason (Experian): Creative strategy remains essential because it provides valuable signals for targeting and engages audiences effectively. In this advanced contextual world, good creative in the proper ad format that you can test and learn from is paramount. It comes back to that feedback loop. We can use that as another signal in this equation to develop and refine the right set of audiences for your targeting needs. Alex (Yieldmo): Creative and ad formats are powerful signals for understanding audience engagement. At Yieldmo, we collect interaction data every 200 milliseconds, such as scrolling behavior or time spent on an ad. This data fills the gap between clicks and video completions, helping us build models that predict downstream actions. Tailoring creative to specific audience groups has always been one of the best ways to improve performance, and it remains essential in this new era of contextual advertising. Throughout my career, I learned that designing or tailoring your creative to different audience groups is one of the best ways to improve performance. We ran many lift studies with analysis to understand how you can tailor creative customized for individual audiences. That capability and the ability to do that on an identity basis is. Our recommendations for actionable marketing strategies Do you have recommendations for marketers building out their yearly strategies or a campaign strategy? Jason (Experian): My recommendation for marketers building out their yearly strategies is to be proactive and start testing and learning these new solutions now. I mentioned addressability and being in the right place at the right time. That’s easier in today’s third-party cookie world. But as traditional identity is further constricted, you will have these first-party solutions that will not be at scale, so you’re less likely to find your user at the scale you want. It would be best if you thought about how to reach that user at the right place at the right time. They may not be seen from an identity basis. They might not be at the right place at the right time when you were delivering or trying to deliver an ad. But you increase your chance of reaching them by building these advanced contextual targeting audiences using this privacy-safe seed ‘opted-in’ user set; this is a way to cast that wider net and achieve targeted scale. Alex (Yieldmo): Build your seed lists, test your formats with different audiences, and understand what’s resonating with whom. Take advantage of some of the pretty remarkable advances in machine learning that are allowing us, really, for the first time to fully uncork the potential and the opportunity with contextual in a way that we’ve never done before.

In 2022, Google began changing the availability of the information available in User-Agent strings across their Chromium browsers. The change is to use the set of HTTP request header fields called Client Hints. Through this process, a server can request, and if approved by the client, receive information that would have been previously freely available in the User-Agent string. This change is likely to have an impact on publishers across the open web that may use User-Agent information today. To explain what this change means, how it will impact the AdTech industry, and what you can do to prepare, we spoke with Nate West, our Director of Product. What is the difference between User-Agents and Client Hints? A User-Agent (UA) is a string, or line of text, that identifies information about a web server’s browser and operating system. For example, it can indicate if a device is on Safari on a Mac or Chrome on Windows. Here is an example UA string from a Mac laptop running Chrome: To limit the passive fingerprinting of users, Google is reducing components of the UA strings in their Chromium browsers and introducing Client Hints. When there is a trusted relationship between first-party domain owners and third-party servers, Client Hints can be used to share the same data. This transition began in early 2022 with bigger expected changes beginning in February 2023. You can see in the above example, Chrome/109.0.0.0, where browser version information is already no longer available from the UA string on this desktop Chrome browser. How can you use User-Agent device attributes today? UA string information can be used for a variety of reasons. It is a component in web servers that has been available for decades. In the AdTech space, it can be used in various ad targeting use cases. It can be used by publishers to better understand their audience. The shift to limit access and information shared is to prevent nefarious usage of the data. What are the benefits of Client Hints? By using Client Hints, a domain owner, or publisher, can manage access to data activity that occurs on their web properties. Having that control may be advantageous. The format of the information shared is also cleaner than parsing a string from User-Agents. Although, given that Client Hints are not the norm across all browsers, a long-term solution may be needed to manage UA strings and Client Hints. An advantage of capturing and sharing Client Hint information is to be prepared and understand if there is any impact to your systems and processes. This will help with the currently planned transition by Google, but also should the full UA string become further restricted. Who will be impacted by this change? Publishers across the open web should lean in to understand this change and any potential impact to them. The programmatic ecosystem supporting real-time bidding (RTB) needs to continue pushing for adoption of OpenRTB 2.6, which supports the passing of client hint information in place of data from UA strings. What is Google’s timeline for implementing Client Hints? Source: Google Do businesses have to implement Client Hints? What happens if they don’t? Not capturing and sharing with trusted partners can impact capabilities in place today. Given Chromium browsers account for a sizable portion of web traffic, the impact will vary for each publisher and tech company in the ecosystem. I would assess how UA strings are in use today, where you may have security concerns or not, and look to get more information on how to maintain data sharing with trusted partners. We can help you adopt Client Hints Reach out to our Customer Success team at tapadcustomersuccess@experian.com to explore the best options to handle the User-Agent changes and implement Client Hints.
