Levelling the Playing Field: Reimagining Digital Advertising After Google - Part 2

As discussions around Google’s dominance in digital advertising continue, a key question emerges: How will the future of Google's Privacy Sandbox unfold, especially in light of potential regulatory actions?

Additionally, given Google's extensive measurement capabilities through platforms like Android, Chrome, and YouTube, what further steps should be taken to create a truly level playing field in the digital advertising market beyond the proposed divestitures?

Google’s Privacy Sandbox has been positioned as a bold step toward a more privacy-centric web, aiming to phase out third-party cookies while maintaining effective digital advertising. However, the initiative’s fate could take a dramatic turn if regulators push for a forced divestiture of the Chrome browser. As the US Department of Justice intensifies its antitrust scrutiny, the possibility of Google relinquishing control over Chrome raises pressing questions about the future of online privacy, competition, and data access.

At the heart of this debate is whether Privacy Sandbox remains viable without Google’s direct oversight of Chrome. If divested, would an independent Chrome operator maintain or alter the framework? More importantly, could this restructuring truly enhance competition, or would it create new challenges for advertisers and publishers navigating an already complex digital landscape?

Beyond Google, the broader implications are profound. A shift in Chrome’s ownership could redefine the balance of power in ad tech, influencing how user data is collected, processed, and monetized. It could also accelerate industry-wide efforts to develop alternative identity solutions—potentially reshaping the future of targeted advertising and consumer privacy. As regulators weigh their options, the industry braces for a transformation that could either curb Google’s dominance or introduce a new era of fragmentation and uncertainty.

Céline Gauthier-Darnis, EVP MENAT & APAC at Equativ, notes that Google Search, which generates nearly 57% of the company’s revenue, has long relied on Chrome as a crucial entry point for growth. She adds that Chrome has not only anchored Google’s self-preferencing for distribution, but also served as a major source of digital signal harvesting. Losing Chrome’s 3 billion monthly users will be a significant blow, likely impacting Google’s search operations in the short-term.

However, Céline Gauthier adds, Google will quickly overcome the impact by re-establishing its ability to harvest digital signals from its wider ecosystem, including Gmail, SSO, Google Pay, YouTube, Google IoT hardware and more. Additionally, Google will quickly shift its focus from browser to its OS and Gemini AI engine.

“Google has been anticipating the departure from browser-based search for a while, so while it will cause short-term disruption, they are well positioned to adapt quickly. Google’s dominance in search is intrinsically tied with its control over the buy-side, sell-side, and measurement ecosystems in digital marketing. To foster real competition and drive better outcomes for consumers, brands, and publishers, this hold must be broken,” she adds.

According to her, intensifying competition from Microsoft, Amazon, Apple and others will push Google to open its AI engines to third-party platforms, enabling new consumer interfaces. This reality will drive the growth of diverse platforms, ending the era where digital journeys begin by ‘Googling it’. Marketers will need to embrace a multi-platform and more balanced channel strategy to navigate this fragmentation effectively.

“For brands, relying solely on Google PPC as we know it risks diminished visibility and performance. Ultimately, diversifying communication channels will be essential to building resilience against technological disruption and thriving in a constantly evolving digital landscape,” she explains.

Google’s Privacy Sandbox is a cornerstone of its efforts to balance user privacy with the needs of advertisers, points out Meher Patel, Founder, Hector. However, he adds, if Google is forced to divest Chrome, the Privacy Sandbox initiative could undergo significant changes:

New Ownership & Direction:A divested Chrome browser may lead to alternative governance over privacy initiatives, potentially affecting implementation and oversight.
Regulatory Scrutiny:Policymakers may scrutinize whether Privacy Sandbox truly enhances privacy or merely shifts control from one Google-owned ecosystem to another.
Competitive Market Effects:The divestiture could lead to a wider variety of privacy-preserving solutions from other ad tech players, fostering innovation and consumer choice.

Ultimately, Patel adds, the broader ad tech industry may need to adapt to a new regulatory and competitive landscape where privacy standards are defined collaboratively rather than dictated by a single dominant player.

Additional measures

Considering Google’s extensive measurement capabilities through tools like Android, Chrome, and YouTube, some additional measures need to be taken to ensure a level playing field in the digital advertising market beyond the proposed divestitures.

According to Meher Patel, while breaking up parts of Google’s ad tech empire is a step toward fairer competition, additional measures are necessary to ensure long-term market equity:

Regulatory Oversight: Continued monitoring of both existing and emerging players in the ad tech space to prevent new monopolistic structures.

Transparency & Data Sharing: Enforcing transparent data access policies that allow advertisers and publishers to use measurement tools without being locked into a single ecosystem.

Interoperability Standards: Creating industry-wide standards for cross-platform advertising measurement and attribution to reduce dependency on Google’s tools.

According to Patel, ensuring a level playing field requires a multi-faceted approach that goes beyond divestiture and actively fosters a balanced, competitive digital advertising ecosystem.

“The outcome of the Google antitrust case could reshape digital advertising as profoundly as the Standard Oil case did for the petroleum industry. If divestitures are enforced, we may enter a new era of heightened competition, transparency, and innovation. Marketers, advertisers, and publishers must stay agile and proactive to navigate these shifts successfully. The strategies that will thrive in this evolving landscape are those that prioritize adaptability, privacy-conscious practices, and open-market collaboration,” he concludes.

Céline Gauthier-Darnis says that while discussions with Google are a step forward, much more is needed. “Regulators should consider separating the entire Google Ad Manager platform (that is, AdExchange and Adserver). Transparency, innovation, and healthy competition in digital advertising are crucial—principles at the heart of Equativ’s mission.”

In summary, if Google is forced to divest Chrome, it could reshape digital advertising, privacy standards, and competition. While Google is well-positioned to adapt by leveraging its broader ecosystem, the industry must embrace diversified strategies and regulatory measures to ensure a balanced and competitive landscape. The coming years will test whether this transformation fosters true innovation or leads to further market fragmentation.
