Earlier this year, at a Signal Shift event in NYC, the IAB Tech Lab officially announced a new open-source initiative designed to shift more digital advertising operations server-side, “providing publishers on the open web with privacy-first control over their monetization that is independent of browser APIs and signal loss.”
The unveiling of Trusted Server, an early proof of concept that the IAB Tech Lab opened up for industry collaboration, was met with varied reactions and some skepticism.
Publishers and media owners expressed hope that this is an opportunity to wrestle back control from the large tech companies and walled gardens. Meanwhile, other entities, with business models heavily reliant on access to client-side data, shared concerns about the current capabilities of the proof of concept.
What is the future of Trusted Server? Can we expect that this initiative will really help restore publishers’ ownership of monetization?
Anthony Katsur and the team at IAB Tech Lab haven’t released a finished specification or product. This initiative is in its infancy.
The proof of concept demonstrates potential and provides a road map for coexisting with browser functionality through phases of development. But for Trusted Server to become an adopted standard, there is a ton of work needed to support all essential pieces of web advertising.
Rich media executions, identity signals and verification solutions (ad fraud, brand safety, measurement) are among some of the key considerations that would take significant effort to shift away from client-side dependencies. The Tech Lab is also hopeful about receiving support from the dominant publisher ad server, Google Ad Manager, which is crucial for adoption.
The Tech Lab invited industry participation in a new task force for this initiative to help define the standards and next steps for Trusted Server, as investment from key players in the ecosystem will be required to get it off the ground.
Some reactions to the Trusted Server concept raised concerns that moving operations server-side could further erode trust in the OpenRTB ecosystem, pointing to ongoing issues with transparency around ID signals, video declarations, bid duplication and fraud. But these issues already exist today and are exacerbated by “rogue” vendors gaining access to the client or by intermediaries manipulating a publisher’s original configurations and signals upstream.
The current client-side model, with vendor code on publisher pages collecting user data, has contributed to data leakage, under-compensation for publishers and increased risk of privacy violations. The browser has become a chokepoint, with companies like Google and Apple limiting the broader market’s capabilities while reinforcing their own data advantages, all under the guise of privacy.
A shift to server-side processing offers a chance to reestablish trust and interoperability by reducing reliance on browser APIs and creating a cleaner, more controlled data environment for publishers. This initiative could drive real transparency, if it results in enforceable industry standards around accountability and signal verification throughout the supply chain, akin to IAB’s ‘schain’ or ‘ID provenance specs.’
While it may not yet be clear how auditing and verification will fit into the Trusted Server concept, one thing is certain: The current proliferation of tags, SDKs and pixels – paired with every vendor defining its version of “truth” – is not a sustainable foundation for the future of digital advertising.
For publishers today, maximizing monetization through programmatic advertising typically means a lot of tech on page. Obtaining consent to comply with privacy regulations, recovering revenue from ad block users, identifying audiences through cookie syncs, sending out bid requests to multiple SSPs – all of this adds weight and latency to the client.
Add in video players, analytics or verification tags, and the exponential effect of a publisher’s direct partners incorporating multiple upstream vendors … the sheer amount of code and network requests originating from the client becomes unsustainable and leads to a terrible experience for users.
The open web will not survive without a shift to solutions that minimize the impact on the client and speed up the delivery of engaging content and advertising experiences.
The industry may continue to debate the finer points of Trusted Server and the future of publishers’ advertising operations, but the general concept of moving toward more server-side processing just makes sense.
Whether this IAB proposal evolves into something the industry adopts or not, giving publishers more control over how data is collected, shared and monetized on their properties is a step in the right direction.
Privacy regulations and industry standards are evolving rapidly, and Optable is built to keep publishers aligned every step of the way. With Optable’s latest update, honoring user consent across regions becomes simpler.
Optable’s Real-Time APIs now support the IAB’s Transparency and Consent Framework (TCF) and the Global Privacy Platform (GPP) privacy strings from Consent Management Platforms (CMPs).
By integrating with TCF and GPP privacy signals in real-time, Optable APIs can dynamically adjust data processing activities based on the consent status provided and the publisher’s configuration. If valid privacy strings are present or if a user is detected in a region like the EU or Quebec, the APIs will enforce the configured consent requirements.
This update underscores Optable's commitment to providing tools that enable responsible data handling and help businesses build trust with their audiences by respecting their privacy choices.
Developed by IAB Europe, TCF helps the ad industry follow privacy laws like the GDPR in the EU. GPP expands on this, addressing laws in California’s CPRA, Colorado’s CPA, Quebec’s Law 25, and other regions—all in a single standard format.
As privacy rules grow more complex, many publishers and advertisers have built their own ways to handle consent. GPP simplifies this with a unified approach that reduces legal risk and makes operations easier.
Optable is a contributor to Project Rearc, the IAB Tech Lab initiative focused on modernizing industry standards, including those related to privacy and identity. Our Co-founder and CPO, Bosko Milekic, joined the IAB Tech Lab Board of Directors in 2024, helping guide these efforts. Supporting GPP is part of our commitment to advancing interoperability and privacy compliance.
Beyond GPP, we’re also actively involved in several ongoing Tech Lab initiatives aimed at improving privacy, transparency, and interoperability across the ecosystem. This includes the Privacy Enhancing Technologies (PETs) working group, where we help define new privacy-safe methods for data collaboration; the development of the PAIR clean room protocol, which we co-authored; and support for evolving standards such as OpenRTB 2.6 ID provenance, Trusted Server, and RTB Containerization.
In the Optable platform, you can now set up API restrictions based on specific consent purposes defined by the IAB. This gives you full control over when data can be read or written, based on what your users have agreed to. By supporting GPP and TCF strings in Optable Real-Time APIs, we help our partners reduce legal risk and operational complexity, without compromising on flexibility or compliance.

I had the privilege of speaking last week at ID5 On The Road: NYC, a gathering of industry leaders focused on the future of identity, privacy, and performance in advertising. The conversations were candid and thought-provoking, reflecting a shared understanding: the industry is being reshaped, and we all have a role to play in building what comes next.
Here are the three most important themes I walked away with:
The era of loosely regulated adtech is behind us. Today, privacy is not a competitive differentiator—it’s table stakes. And yet, many in the industry are still treating it like a box to check rather than a design principle.
In her remarks, Hillary Slattery, Director of Programmatic at the IAB Tech Lab, said it best: we need to “avoid the ick.” That means building privacy-safe solutions that put consumer rights and transparency at the center. It’s no longer optional—regulation is enforcing it, and user trust demands it.
Another phrase that stuck with me: “Trust but verify.” While there are more tools than ever to manage consent and uphold consumer data preferences, the burden doesn’t stop at selecting a vendor. It’s on each of us to implement, test, and continuously verify that privacy systems are functioning as promised.
Publishers in particular hold a critical responsibility here. They are the custodians of user relationships and are uniquely positioned to safeguard consumer choice at the point of engagement.
The fragmentation caused by privacy regulations and deprecation of legacy signals has only reinforced the importance of robust identity solutions. Identity is no longer just a tactical lever—it’s become foundational to campaign execution, measurement, and accountability.
There’s a clear acceleration in the adoption of identity graphs, but the message from the stage was clear: scrutinize what’s under the hood. If a solution suddenly returns 35 identifiers, something may be misaligned. Too much noise in identity can dilute performance and create more confusion than clarity.
That’s why efforts like the IAB Tech Lab’s provenance documentation are so promising—they’re bringing standardization, transparency, and consistency to how identity solutions are sourced, matched, and validated. In a landscape built on trust, this level of accountability is non-negotiable.
One of the most compelling shifts I observed at the event is the emergence of a BYOA: Bring Your Own Audience approach to targeting & campaign execution. This was evident particularly agencies—who are no longer content to rent identity and targeting infrastructure from external technology partners.
Instead, a “build vs. buy” mindset is taking hold. Agencies are investing in in-house identity graphs enriched with their own first-party data and user attributes. Rather than relying on a patchwork of vendor solutions, they’re designing bespoke systems that offer tighter control, improved efficiency, and better integration with their measurement frameworks.
This Bring Your Own Audience (BYOA) approach is transforming the role of publishers as well. To remain competitive, media owners must be able to meet buyers where they are—whether that means improved identity match rates, support for clean room environments, or delivering higher-performing inventory in both programmatic and direct channels.
Measurement also took center stage. It’s not just about reaching the right person; it’s about proving that the interaction led to a meaningful outcome. Buyers are increasingly demanding that media partners deliver both addressability and attributable performance.
Speaking at ID5 On The Road: NYC was a welcome opportunity to connect with peers navigating the same complex terrain. While the challenges in front of us are significant, the momentum toward a more trustworthy, transparent, and consumer-centric adtech ecosystem is undeniable.
What’s clear is that the future will be shaped by those who lead with integrity, adapt with intention, and put the consumer first—every step of the way.

The advertising landscape is rapidly evolving, with privacy concerns reshaping how we approach direct sales. As we navigate this new terrain, it's crucial to understand the impact of cookie deprecation and explore innovative solutions to maintain the effectiveness of direct campaigns.
At the heart of this challenge lies the critical need for a comprehensive identity solution that can bridge the gap between user privacy and effective revenue optimization. An identity graph and it's data spine serve as the cornerstone of this solution, underpinning the essential requirements for monetization across a publisher's diverse revenue channels. This powerful tool not only supports direct sales efforts but also enhances programmatic advertising, subscription models, and other revenue streams.
As we delve into the intricacies of maintaining direct sales in the age of privacy, it becomes clear that a well-implemented identity graph is not just a technological asset—it's a strategic imperative for publishers looking to thrive in an increasingly privacy-centric digital ecosystem.
Direct sales in advertising rely on a data-driven virtuous cycle that encompasses several key phases:
These phases are interconnected, with insights from each stage informing the others and driving renewals and upsells.
The cookie collapse threatens to break the upsell cycle by hampering a publisher's ability to use audience and insights.
We can further break down the 3 Sales Phases into several supporting tactics:
The impending loss of third-party cookies significantly impacts various tactics across all phases of direct sales. This disruption threatens to break the virtuous cycle that has long been the backbone of successful advertising campaigns.
Each Tactic of Sales Phases are uniquely challenged by cookie deprecation.
Buyers today have largely the same requirements, if not more stringent ones, compared to pre-cookiepocalypse when it comes to placing reservation based buys with publishers directly.
To overcome these challenges, publishers and ad tech vendors must adapt and innovate. If you want to compete for direct sales, you can no longer rely on yesterday's technology.
Here are key strategies to consider:
The world is moving towards "composable everything," as the distinctions of SaaS tools blur amidst growth and market opportunity recalibration. The "standalones" are dead, and long live the interoperable solutions that make your stack come to life.
At the heart of this all lives a data spine.
A data spine serves as the central support structure within a larger ID graph. It provides crucial linkages between different identifiers, forming the foundation for a more comprehensive understanding of individuals.
Here we see how the Data Spine sits within the larger ID Graph. It is the supporting structure of making identity usable, but it does not carry the essential metadata that comprises the larger ID Graph or User Graph.
Here is a handy chart of why you would want an independent Data Spine. Remember that many systems include a Data Spine but the typical customer does not interact with it or support it. Having access to and controlling the data spine gives several unique advantages:
Publishers should focus on:
It is worth a read of the IAB Tech Lab 's ID-less Solutions Guidance (in Public Comment mode at time of publishing) for a deeper look at how different ID-less solutions can bolster various sales phases and tactics.
Many publishers think that they can't orchestrate or participate in data collaboration (clean rooms), but there are actual several ways to overcome this.
Here are the most common reasons why publishers don't, won't or can't participate in data collaboration:
I want publishers to strongly consider the use of alternative IDs when it comes to clean rooms and data collaboration. This does not just have to be with 1:1 identifiers like email, but it is very important to consider the buyside expectations when planning for collaboration.
Yes, HEM Matching, and even probabilistic IDs, may be controversial here-- especially if you are not disclosing (or worse, misrepresenting) your methods. However, disclosure and clear communication will provide those bridges and trust that are essential.
As we enter this new era of privacy-first advertising, publishers and ad tech vendors must adapt their strategies to maintain the effectiveness of direct sales. By embracing data spines, leveraging first-party data advantages, and exploring new collaboration methods, we can continue to deliver value to advertisers while respecting user privacy.
The future of direct sales lies in our ability to innovate and find common ground in a rapidly changing landscape. Let's rise to the challenge and (re)shape the future of advertising together.
We continue to spotlight our clients, showcasing how they navigate data management and their advertising strategies. The Globe and Mail, a leading Canadian publisher, is at the forefront of adopting secure and innovative advertising practices. In this second part of our interview series, we spoke with Soleil Adler, Data Optimization Manager, about their successful campaign with VIA Rail. This conversation highlights the importance of a well-structured data strategy and the ongoing pursuit of excellence to achieve results that exceed expectations. If you missed the first interview, you can read it or watch it here.
Discover all four perspectives on the successful partnership around data collaboration between publisher the Globe and Mail, advertiser VIA Rail, agency Omnicom Media Group and tech provider Optable in the AdExchanger article.
The objective was to determine if using The Globe and Mail’s data enriched with a client's first-party data would outperform solely using The Globe’s data. VIA Rail’s campaign goal was to generate awareness and encourage planning for the next trip with VIA Rail.
We matched all the Globe and Mail readers with three separate VIA Rail audiences: Lapsed Travelers, Mid-Week Travelers, and Travelers from the Last 3 Years to gather insights and then create a look-alike.
We conducted an ABC test. For tactic A, we targeted on-site content focused on inventory using audience insights from the match. For tactic B, we created a lookalike audience based on the last three-year Travelers audience match. Tactic C served as our control, targeting The Globe’s domestic traveler audience.
Once we identified travelers who had purchased tickets within the last three years through our platform, we matched them with all of the Globe readers and gathered insights from this match. The insights revealed that travelers were highly interested in the Personal Finance, Business Opinion, and Investing sections. Therefore, we targeted our inventory towards those sections.
We created a look-alike audience to reach potential new customers with similar interests in domestic travel. We achieved this by matching the audience to Optable’s prospecting Clean Room and assessing the model probability to ensure efficient scale and attribute, and then activating it.
With VIA Rail, we have seen a 3.4 times increase in reach. We are continuing to use these tactics in new campaigns and conducting frequent data matches to improve our data strategy as we move forward. One thing we are focusing on is matching ad exposure with ticket sales to determine the contribution and identify who purchased the ticket after being exposed to the ad on The Globe. We are also working on another use case where we are creating a suppression segment to specifically avoid targeting existing ticket purchasers.
The Globe and Mail's strategic approach to data collaboration and Clean Room technology highlights the transformative potential of these tools in digital advertising. By integrating advanced data solutions, focusing on meaningful metrics, and leveraging successful case studies like the VIA Rail campaign, they continue to innovate and lead in the realm of data-driven advertising.
With the continuing loss of third-party signals, contextual targeting is becoming a popular alternative to ID-based solutions for delivering targeted advertising. It involves classifying web pages, as well as video and audio content, based on content categories and sentiment using keywords, titles, and meta tags. The classifications are then used to build audiences for targeting or suppression campaigns and, oftentimes, to curate deals to make inventory more attractive.
Oracle's Grapeshot, a widely adopted contextual product, recently announced the sunset of its entire portfolio. With little time to plan, publishers and marketers have quickly sought replacement solutions. While there are plenty of data providers in the market who can provide contextual categorization through natural language processing (NLP) or other methods, one of the biggest challenges publishers face is integrating this data, normalizing it, and making it actionable through simple audience-building UI and integration with activation end-points.
Optable can help publishers recreate audiences at scale with minimal revenue loss. This guide will show you how to use our platform to manage third-party contextual solutions. Our customers can then use our platform and tools to build audiences from contextual signals.
While external data signals are dwindling, data collaboration and Clean Room technology have become pivotal for maximizing monetization strategies. To gain insights into the transformative approach for publishers, we spoke with The Globe and Mail’s commercial data optimization team. They shared their journey and strategies, leveraging collaboration around customer data.
In the first part of our interview, Kabil Rahaman, the Head of Data Optimization, explains how data collaboration is integrated into their strategy.
We’ve undergone significant changes in the past few years, with a focus on building around our data warehouse. One of the main reasons we chose Optable as our partner is because the process was relatively easy. Leveraging Optable's connection to our data warehouse made it a no-brainer for us to develop that capability.
However, focusing solely on revenue provides a limited viewpoint of our impact. To gain a more comprehensive understanding, we look at our interactions with partners and the discussions we have. These conversations are a valuable starting point for measuring revenue opportunities and tracking our progress.
Data collaboration is viewed as an extension of our data strategy, enabling partners to bring their data to The Globe's environment for media investment planning. The key metric measured here is the financial success of whether we've matched an audience, targeted a specific audience, or used insights from that match to plan a campaign.
The Globe and Mail’s strategy began over ten years ago. Unlike many digital news media publications that chase clicks and traffic, we focus on providing high-quality news journalism behind a paywall. We believe in a balanced value exchange for readers, whether they pay and subscribe or not. The goal is to nurture a reader’s journey from being anonymous to registering. We collect data at all stages of this journey, ensuring a fair exchange for the news and media consumed. This approach helps us better understand readers' preferences and connect them with better advertising.
The Globe and Mail follows a readiness checklist that includes having a first-party data strategy and agreement from key stakeholders (IT, Security, Legal), including an executive sponsor. The presence of a person willing to take responsibility and be accountable for the success of the program is crucial.
Media agencies, as data controllers or data stewards, face the challenge of managing the expectations of multiple stakeholders while handling sensitive customer data for advertising. Experience in uploading customer lists to platforms like Meta or Google makes collaboration easier.
Success in data matching stems from mutual learning opportunities between two customer data owners. Our team is very obsessive about the relationship their readers have with ads, helping advertisers connect with receptive readers and audiences. I see our success in giving brands the chance to connect with our readers in a meaningful way and providing learning opportunities for both the brand and The Globe through customer list matching.
The test-and-learn approach begins with curiosity, aiming to validate an assumption or theory for a partner. It’s a highly collaborative process designed to produce structured tests to address business challenges. We use the acquired insights to improve campaign planning and segmentation.
As an optimistic person, I believe that a low audience match provides an opportunity for customer growth and acquisition. In this scenario, tactics include creating look-alike models, leveraging content insights, and excluding current customers.
It's important to test different tactics and learn from the results. Compare these tactics with a publisher's first-party audience to determine if there's a lift or difference in how the publisher defines their own audience compared to how you would match.
