Contextual audiences with DSPs and Ad Networks in the iOS and Privacy Sandbox Future


In today's dynamic digital landscape, privacy is at the forefront of technology innovation. While the tech industry grapples with the evolving challenges of user data, contextual Demand Side Platforms (DSPs) and ad networks are emerging as pivotal players. Apple's relentless pursuit for user privacy, coupled with Google's Privacy Sandbox, has set the stage for a major shift in online advertising. But what does this mean for businesses, marketers, and advertisers? Let's delve deep into this transformation and its implications.

The Rise of Contextual Advertising

With the ongoing emphasis on privacy, the age-old practice of behavioral targeting is facing significant hurdles. Instead, contextual advertising is taking center stage. Unlike behavioral targeting, which leans on users' past behaviors, contextual advertising focuses on the present. It places ads based on the content a user is currently viewing, ensuring relevancy without delving into past digital footprints.

Why Contextual DSPs and Ad Networks?

In the rapidly evolving digital advertising ecosystem, understanding the significance of publishers has become paramount, especially in a world that increasingly leans towards contextuality. At the core of this change lies the challenge of identifying which publisher served an impression. This information becomes the essential variable for successful advertising.Take, for instance, the collaboration between BMW and the Financial Times. BMW, in a contextual world, chooses to advertise on the Financial Times due to its strong contextual alignment with its target audience. However, there lies a challenge: privacy thresholds could potentially prevent advertisers, like BMW, from identifying that their advertisement ran on the Financial Times. The problem intensifies when one considers that ad platforms often lack clarity on the exact locations where ads are being served. This creates a gap, and advertisers and platforms need to bridge it to determine if a particular campaign, for instance, genuinely ran on the Financial Times.This feedback loop becomes even more critical when considering the scale. Imagine running campaigns across hundreds or thousands of publishers. If post-backs (feedback from advertising platforms) omit publisher details, how can advertisers optimize their campaigns? Taking the previous example, without this data, advertisers wouldn't discern the effectiveness of publishers like the Financial Times for a brand like BMW. While the BMW-Financial Times correlation might seem straightforward, the reality is murkier for most apps that lack comprehensive demographic data for all publishers and apps running ads. This makes the role of DSPs indispensable.In the past, during the behavioral era, advertisers didn't emphasize the specific publishers their ads ran on. When device IDs and the extensive profiling knowledge of users were prevalent, it mattered less which publisher was involved. The system could recognize patterns, say, of users favoring a certain genre of apps and place bids accordingly, irrespective of the exact publisher. But as we migrate away from this, the focus has shifted dramatically towards understanding the audiences each publisher caters to and determining if there's an affinity fit for the campaign in question.

Targeting via Ad Networks in the Privacy-First Era

The shift to a privacy-first approach means ad networks have to reinvent their strategies. With Apple's SKAdNetwork 4 and the phasing out of third-party cookies, the challenge is evident: how can advertisers remain relevant without compromising user privacy?

Data-Driven Personalization Without Personal Data

Modern ad networks are increasingly focusing on data-driven personalization. They aim to provide customized ad experiences without relying on personal data. Techniques such as cohort-based advertising, where users are grouped based on interests rather than individual behaviors, are gaining traction.

Privacy Sandbox: The New Kid on the Block

Google's Privacy Sandbox promises a middle ground, aiming to satisfy advertisers' needs while upholding user privacy. With tools like the Federated Learning of Cohorts (FLoC), Google is proposing solutions that allow for group targeting rather than individual tracking. Advertisers can still tailor their campaigns effectively without directly accessing user-specific data.

The Evolution of Conversion Metrics

In the world of iOS, the introduction of conversion values in platforms like SKAdNetwork 4 underscores the industry's move towards precision and accountability. While advertisers may no longer have the depth of data they're accustomed to, they're gaining tools that offer sharper insights into immediate user interactions post-ad viewing.

Navigating the Future of Digital Advertising

The road ahead for digital advertising is both challenging and exciting. With the pivot towards privacy and the rise of platforms prioritizing user interests, businesses have a unique opportunity to reevaluate their strategies.

Building Trust in the Digital Age

For advertisers and businesses, the key lies in building trust. The modern user values privacy, but they also appreciate relevancy. The challenge, then, is to deliver targeted ads without infringing on that trust. Contextual DSPs and evolved ad networks provide the tools to achieve this balance.


The shift towards a more privacy-centric digital landscape is undeniable. As Apple's iOS changes the rules of the game and Google's Privacy Sandbox brings forth new tools, advertisers need to stay agile and informed. Contextual DSPs and modern ad networks are not just solutions to current challenges; they're the future of digital advertising. Embracing them is not just about adapting; it's about thriving in the new era of digital marketing.
