Ongoing signal loss is driving marketers, agencies, and platforms to turn to supply-side advertising. By using first-party data from publishers and platforms, supply-side advertising has the potential to deliver high-quality audience and context for more effective ad targeting.
The supply-side refers to the publishers and platforms that sell advertising inventory. These companies have access to first-party data about their users, which can be used to target ads more effectively. By tapping into supply-side advertising, you can overcome the challenges of signal loss and target ads more effectively.
To shed light on this topic, we hosted a panel discussion at Cannes, featuring industry leaders from Audigent, Captify, Newsweek, Pubmatic, Truthset, and Experian.

In this blog post, we’ll explore how partnerships between supply-side channels and publishers are working to enhance advertising opportunities while balancing the need for transparency and control in programmatic ad buying.
Shift toward supply-side advertising
Traditionally, the demand-side dominated the programmatic media buying chain due to an abundance of supply. However, with the emergence of finite data and its interpretation, collaboration between supply-side technology companies and publishers is required to redefine these economics.
It’s no longer sufficient for the demand-side to blindly negotiate prices based on limited knowledge. Marketers can still define their target audience, but effective communication is key. This presents an opportunity for premium journalistic outlets to guide the industry’s understanding of how data from the supply-side impacts media buying economics in the future.
“Supply-side technology partnerships with publishers are now in a position to shape the economics of programmatic media buying as there is a finite amount of data. It’s crucial for supply-side technology companies to collaborate with publishers to shape these new economics. This presents an opportunity for premium journalistic outlets to provide guidance on how data from the supply-side can affect the future of media buying.”

Democratizing data from the supply-side
Cookies haven’t brought significant benefits to premium publishers. They mainly serve to retarget users from sites like The Wall Street Journal to advertising sites. This approach primarily serves the purpose of generating revenue.
The elimination of third-party cookies presents an opportunity for premium publishers to shift this dynamic. By using their knowledge of first-party audiences, and using identifiers like Experian’s LUID, publishers can own and understand their audience data, which can then be modeled.
Here’s how publishers can win
Establishing a connection with consumers and emphasizing the value exchange is essential to building trust. Determining what incentives and benefits consumers find meaningful will be crucial in gaining their opt-in.
With consumers
The Apple tracking transparency initiative, specifically the deprecation of IDFA signals, had significant implications for mobile app developers. Overnight, opt-in rates plummeted, causing a drastic decline in iOS ad monetization. To combat this, developers focused on demonstrating the value exchange to consumers—better ad experiences and personalized content.
By articulating the benefits over a couple of years, opt-in rates increased from 10-15% to 30-40%. The key takeaway is the need to effectively communicate the value exchange to consumers.
With partners
Trust plays a crucial role in planning your first-party data strategy. Publishers, advertisers, and data partners highly value their proprietary data. However, there are concerns about how it’s used, mishandled, or leaked in the ecosystem. Building trust between partners is essential. It’s important to work with trustworthy partners who are agnostic, committed to innovative solutions, and globally oriented. These partners can help navigate the complexities of laws and regulations. Choosing the right partners is crucial in a world where first-party data is a key asset.
“Power is shifting toward brands that have strong relationships with customers and possess first-party data. As the ownership of customer data becomes more important, it is crucial to establish a first-party data strategy to better serve customers and adapt to changing market dynamics.”
chip russo, president, truthset
Balance probabilistic and deterministic data
Focus on building trust with consumers and collaborating with reliable companies to share data. However, it’s important to remember that achieving a 100% opt-in rate is unlikely.
The cookie, which has become omnipresent, requires us to shift our strategic thinking. We need to consider both deterministic and probabilistic approaches instead of viewing them as mutually exclusive. The landscape will be fragmented, with some consumers opting in and others not.
“Probabilistic and predictive audience data holds immense potential. With the power of AI, we can expect enhanced performance and efficacy in media campaigns. At Audigent, we firmly believe that this data will outperform deterministic data, making it an integral part of our strategy.”
drew stein, ceo, audigent
Premium content
Trust plays a crucial role in leading to premium content. By placing trust in the best media brands, data, and technology partners, we can expect to see improvements in media, journalism, and advertising. This shift may have a direct impact on the long tail of free natural resources, making it more challenging for them to thrive. However, this change is ultimately beneficial since it promotes higher-quality media experiences overall.
“The homepage surface is making a comeback in the publishing industry, proving its value in establishing a direct connection with readers. While we acknowledge the importance of technology partnerships for addressability and identity, our core competency as a publisher remains outstanding journalism that captures and engages great audiences.”

Originally appeared on Adweek The advertising industry is experiencing a significant shift resulting from Oracle's market exit. Over the years, Oracle’s advertising tools—built through key acquisitions like Crosswise, BlueKai, Datalogix, and Grapeshot—have become essential for many marketers, data providers, and platforms. With Oracle’s departure, stakeholders are left searching for reliable alternatives to maintain their data-driven strategies. While this transition may seem daunting, it presents a unique opportunity to reassess audience and identity solutions. With the growing importance of adaptability and interoperability, now is the perfect time for advertisers, agencies, publishers, and platforms to adopt future-focused strategies. Oracle’s legacy: A combination of acquisitions Oracle’s advertising business wasn’t a unified solution but a collection of acquired technologies. Crosswise provided a cross-device identity graph; BlueKai offered a robust data management platform (DMP); Datalogix specialized in offline purchase data; and Grapeshot was known for its contextual targeting. Together, these tools powered a comprehensive offering for advertisers, data providers, and platforms. Yet, much of Oracle’s advertising success stemmed from the external data it used. For example, many of Oracle’s automotive audiences relied heavily on third-party data, largely powered by Experian data. This means that while Oracle may no longer be an option, many of the services marketers depended on through Oracle are still available from Experian, ensuring continuity. What this means for advertisers and agencies For advertisers and agencies, Oracle’s exit means losing access to its syndicated audiences. Fortunately, this doesn’t have to cause a major disruption. As one of Oracle’s primary data providers, we've mapped Oracle’s audiences to our own, ensuring marketers can easily maintain their targeting strategies without losing performance or efficiency. With access to over 2,400 syndicated audiences across key verticals such as demographics, automotive, retail purchases, or financial data, advertisers can continue their campaigns with confidence and precision. What sets us apart? Powered by data ranked #1 in accuracy by Truthset, our audiences are built on reliable, offline, deterministic data — like name, address, phone number, and email. This means advertisers can be confident that they are reaching the right audiences across all channels. With our audiences available across 30+ ad platforms, including programmatic, TV, and social media, advertisers and agencies have easy access to keep their campaigns running. For advertisers that ran audience targeting using Grapeshot's Contextual Platform, our new Contextually-Indexed Audiences are a replacement built for the evolving digital media landscape. By combining the precision of audience targeting with the flexibility of contextual targeting, marketers get a privacy-safe, yet scalable way to target audiences that is not reliant on cookies or other user identifiers. Marketers can activate these audiences through leading demand-side platforms (DSPs) or through Audigent private marketplaces (PMPs). A new opportunity for data providers Oracle’s marketplace has long been a crucial distribution channel for third-party data providers, particularly through BlueKai. With its closure, providers have an opportunity to explore new onboarding services and marketplaces that offer similar or even better reach and effectiveness. New alternative onboarding solutions are emerging, particularly in areas like TV and digital, ensuring that the loss of Oracle’s services does not leave a significant gap. These solutions are being built to overcome the challenges typically present with data onboarding — complicated integration processes, limited ID matching capabilities, and opaque pricing structures. One such solution is Experian’s new Third-Party Onboarding. What sets us apart? With our digital and offline identity capabilities embedded within this solution, data providers receive superior programmatic and connected TV (CTV) reach and addressability compared to the competition. The first data providers – Adentro, Kontext, L2, and Webbula – are already using this solution to increase the adoption of their audiences and maximize their revenue. Additionally, new marketplaces are emerging that aim to fill the void left by Oracle, offering distribution to key destinations and providing data providers with continued access to advertisers who require high-quality, third-party data. Platforms shift to new audience solutions Platforms that relied on Oracle for third-party data and audience onboarding are now facing challenges in maintaining their ability to target specific audiences. This could affect their inventory's attractiveness to buyers. However, we offer a seamless solution for platforms looking to replace Oracle’s capabilities. As one of Oracle’s primary data providers, we've already mapped Oracle’s audiences to our catalog of over 2,400 syndicated audiences. Platforms can continue providing precise audience targeting and ensure advertisers receive the performance that they demand. Additionally, Third-Party Onboarding builds upon the investment and infrastructure used to distribute our own audience segments, providing platforms with audiences from leading third-party data providers. Moving forward: Embracing connectivity We're dedicated to powering data-driven advertising through connectivity. With best-in-class syndicated audiences, new Contextually-Indexed Audiences, and an easy-to-use Third-Party Onboarding solution, we're enabling advertisers, agencies, data providers, and ad platforms to improve their marketing operations. Oracle’s departure marks the end of one era, but it also opens the door to a future where collaboration, interoperability, and connectivity define the landscape. By choosing partners like us, advertisers, agencies, and platforms can ensure they remain agile, innovative, and well-equipped to thrive in this new era of data-driven marketing.

Brands are increasingly focused on offering personalized experiences while respecting consumer privacy. Addressability enables them to reach specific audiences with relevant messages, and personalization crafts unique content that aligns with each audience's interests and needs. By combining these strategies, brands can create more relevant and effective marketing campaigns. With new regulations and signal loss reshaping the landscape, alternative identifiers like the ID5 ID and The Trade Desk's Unified I.D. 2.0 (UID2) are gaining importance. These tools give advertisers a more holistic view of consumers across channels, enhancing personalization and addressability even as traditional third-party cookies lose relevance. To shed light on this topic, we interviewed experts from Audigent, Basis Technologies, CvE, ID5, MiQ and others. They shared insights on navigating privacy, utilizing new identifiers, and enhancing personalization with consent. Drawing from their perspectives, we've identified five considerations to help brands adapt and succeed in this evolving landscape. 1. Embrace a privacy-centric approach With the increasing focus on consumer data protection, prioritizing privacy in your addressability efforts is essential. Implement strict data guidelines to protect personally identifiable information (PII) and maintain compliance with state-specific regulations. To achieve this, empower consumers by providing clear and transparent choices about data sharing and honoring their preferences. Avoid targeting based on protected categories or sensitive information. By adopting a privacy-first mindset, you can build consumer trust while still delivering relevant advertising experiences. “It's important to champion consumer privacy and the free internet. We need to strike a balance between the two. This balance is essential for our jobs, the economy, news, politics, and all the valuable content and information we rely on.”Drew Stein, Audigent 2. Personalize with consent Consumers are more willing to share their information when they see clear benefits. In fact, over half of shoppers—and two-thirds of Gen X and Millennials—express a desire to receive holiday shopping deals directly from their preferred brands1. By offering value through loyalty programs, special offers, or interactive platforms, you can personalize experiences without compromising privacy. To implement this strategy, encourage consumers to share their preferences and needs by being transparent and giving them control over their data. This approach builds trust, empowers your audience, and enhances personalization. “Building personalization based on the data consumers have consented to share should lead to a positive experience that drives better engagement because it's relevant to them.” April Weeks, Basis Technologies 3. Personalize with contextual targeting Contextual targeting involves delivering ads based on the content users are currently engaging with rather than user identifiers. By focusing on personalization through contextual targeting and dynamic content, you can align your strategies with your audience's real needs and interests. This approach allows advertisers to reach consumers on websites with more visitors matching the demographics, behaviors, or interests they want to target. “Personalization absolutely can thrive. We have various solutions, all utilizing IDs for targeting and personalization. Beyond that, we can also personalize using context, geo-contextual data, and creative strategies.” Georgiana Haig, MiQ 4. Use alternative identifiers As advertisers move beyond third-party cookies, exploring alternative identifiers offers reliable means to connect with consumers. Options like email addresses or device IDs provide direct connections, improving targeting accuracy. Utilize identity graphs to link different signals and identifiers to establish strong ties to individual users or households. This approach maintains, and can even enhance, your ability to reach the right audience and measure campaign performance. “It's not just about maintaining addressability. It's about massively improving addressability. When we run tests with some of our clients, they're seeing 30, 40, 50, 60% incremental reach by using ID5 versus cookies.” Mathieu Roche, ID5 5. Build partnerships Navigating the complexities of addressability doesn't have to be a solo effort. Partnerships between brands, publishers, and tech providers can lead to innovative solutions that benefit everyone. Consider engaging in data partnerships to access new audience segments without maintaining extensive data. Collaborations focused on your tech stack can enhance your ability to deliver personalized content effectively and at scale. “The rise of second-party data partnerships is going to be an interesting trend over the next couple of years. And if you need mass scale across the world, I think that's a much more cost effective and scalable way to do it.” Paul Frampton, CvE Steering toward success The future of addressability and personalization hinges on your ability to adapt to the changing privacy landscape while delivering meaningful, personalized experiences. By focusing on these five key considerations, you can navigate the complexities of modern advertising, build stronger relationships with consumers, and drive sustainable growth.
