Maximize ad targeting with supply-side advertising

by Hayley Schneider 5 min read August 22, 2023

The shift toward supply-side advertising

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.

Watch the recording of our Cannes panel, "Data on the sell-side"

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.”

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.”

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.”

Uncovering hashed email: you may be sitting on a goldmine of customer data and don’t even know it

Email hashing was originally intended to be used as an email security feature that has ended up being a very powerful marketing tool. A hashed email is a cryptographic function that changes an email address to a random code which can be used as an anonymous customer identifier. This code is privacy-safe and cannot be traced back to the customer’s email address. However, this hashed email can function like a digital passport that traces every behavior and action a customer takes when logged into an account that is authenticated with an email, making hashed emails a goldmine for customer data. Today emails are used across traditional publishers and within the CTV ecosystem; tying them to more consumer touch points than ever before. Why the emphasis now? Cookies are on their way out the door and have been the primary way that many marketers have tracked their existing and potential customers. In order to replace this granular level of data, marketers are likely going to need multiple solutions. With so many cookieless solutions and IDs appearing in the marketplace, the mapping of the customer journey is bound to be fragmented. Relying on first-party data, such as hashed email, is just one way to reduce that fragmentation; as it can serve as an authenticated starting point for cross-device identity resolution that can be leveraged for targeting, personalization and measurement. How can Tapad + Experian help? Tapad + Experian's Hashed Email Onboarding is a privacy-safe way to connect consumer email addresses to their related digital devices and other digital identifiers through high precision probabilistic identity. By onboarding hashed emails and incorporating them within your Tapad Graph file you can: Build a more holistic view of individuals and households and their relationship to email addresses in your first-party data set Leverage these relationships for increased cross-device scale for targeting Employ personalization tactics at the household or individual level across devices Create new audience segments and look-alike models for cross-channel activation Design more inclusive measurement and attribution for customer journey mapping Tapad, a part of Experian has built a hashed email onboarding product feature that works with the existing flexibility of The Tapad Graph to deliver the most holistic consumer view, combined with the attributes you need, in the structure that works best for your business objectives.

Connect the disconnect in your CTV universe

The result of epic shifts from traditional cable to streaming television, the CTV ecosystem is experiencing compounded fragmentation, making it challenging for marketers to leverage in the most effective way for both activation and measurement. Heralded as the hot new household level device for highly engaged viewers, CTV brings massive opportunities for brands to move users down the funnel and incorporate CTV into their attribution modeling post-campaign. Leveraging CTV IDs within a cross-device identity resolution strategy can yield big benefits if you know how to do it right. Check out our breakdown of today’s CTV landscape to help you better understand how and what you can leverage for activation and measurement in the streaming-verse today. CTV Ecosystems as identifiers (for illustrative purposes only) This is just a small peak at the players and complexities of CTV IDs available for marketers today, but it illustrates the need to understand what IDs can benefit your strategies and where you can use them. Addressability and attribution Not all CTV devices and IDs are addressable; or have ad slots for biddable inventory for advertisers. For example, Apple TV devices and Apple TV + are not ad supported, but could still appear within an identity graph for measurement purposes; helping understand customer behavior and habits, which can inform marketing strategies. Having a household to individual view that's as inclusive as possible can provide valuable insights. CTV identity strategy Whether or not CTV devices or apps are addressable for advertisers, they can bring immense value when leveraged as part of a holistic identity resolution strategy. As a household level device with user authentication it can provide marketers a top-down view; unlocking household:individual targeting opportunities and unification of IDs at both levels for frequency management and customer journey mapping Get started with us Tapad, part of Experian, offers CTV ID onboarding and extension to our CTV ID Universe as a part of The Tapad Graph suite of products.
