Technological and Legal Shifts Shaping the Industry
The online advertising industry is undergoing a paradigm shift, driven by significant technological and legal changes. These developments are challenging the traditional business model of tracking users across websites to deliver targeted ads. Attorneys from Sidley Austin LLP explore how these trends are reshaping the digital advertising ecosystem and their far-reaching implications for stakeholders.
As the digital advertising landscape evolves, companies in this multi-billion-dollar industry must adapt to survive. The online advertising industry’s foundation, built on targeted behavioural advertising, is being destabilised by regulatory changes, shifting consumer expectations, and technological advancements. Understanding these trends is critical for advertisers, technology firms, and consumers alike.
The Pillars of Targeted Behavioural Advertising
At its core, the online advertising ecosystem revolves around targeted behavioural advertising. This model involves tracking user behaviour across websites through cookies and similar technologies, creating detailed profiles, and delivering personalised advertisements. The information gleaned from tracking—a user’s browsing history, search queries, and online purchases—enables advertisers to tailor their messaging, increasing relevance and effectiveness.
The cornerstone of this model has been third-party cookies. These small text files, placed on a user’s browser with the website operator’s permission, facilitate cross-site tracking. They allow advertisers to monitor user behaviour across the internet, enabling the delivery of ads tailored to individuals’ preferences and interests.
However, the reliance on third-party cookies and similar tracking mechanisms is increasingly under scrutiny. Changes in consumer attitudes, technological advances, and emerging legal frameworks are converging to challenge this long-standing model.
Technological Trends: Reducing Dependence on Third-Party Cookies
One of the most significant technological shifts is the gradual elimination of third-party cookies. Google, whose Chrome browser commands roughly two-thirds of the market, is at the forefront of this change. By the end of 2024, Chrome will phase out support for third-party cookies, effectively severing advertisers’ ability to track users across the web using this tool. This decision aligns with broader industry trends emphasising consumer privacy and transparency.
Apple has taken similar steps. Its Safari browser, alongside smaller competitors, already blocks third-party cookies and cross-site tracking by default. Moreover, Apple’s mobile ecosystem has adopted a more aggressive approach to privacy. Through its App Tracking Transparency (ATT) framework, Apple requires app developers to obtain explicit consent from users before tracking their activity across other apps and websites. This consent mechanism prominently displays a pop-up, making privacy choices more accessible and transparent to consumers.
In addition, Apple mandates that developers disclose the data they collect and use for tracking. Google has announced plans to implement similar requirements for Android apps, signalling a broader trend toward user-centric data practices across mobile platforms.
Technological innovators are also exploring new models to minimise invasive tracking. Brave, a privacy-focused browser, offers an alternative revenue model by sharing ad revenue with users who opt in to view advertisements. Similarly, the Global Privacy Control (GPC) initiative aims to create a universal privacy standard that enables users to set preferences across all websites and devices, ensuring consistent enforcement of privacy choices.
Legal and Regulatory Pressures: Empowering Consumer Choice
The technological shift away from third-party cookies is paralleled by new legal frameworks designed to enhance consumer privacy. States like California and Virginia have enacted comprehensive privacy laws that grant individuals greater control over their personal data.
California’s Privacy Rights Act (CPRA) and Virginia’s Consumer Data Protection Act (VCDPA), both effective in 2023, represent significant milestones. These laws provide consumers the right to opt out of the sale or sharing of their data for targeted advertising. Businesses must comply by enabling mechanisms for consumers to exercise these rights effectively.
Critically, while these laws do not explicitly prohibit first-party advertising—ads based on data collected directly from a business’s own properties—they do empower consumers to opt out of profiling activities. Profiling, broadly defined, includes analysing personal data to predict preferences, interests, or behaviour, which could indirectly impact first-party advertising strategies.
These regulatory shifts reflect a growing consensus that individuals should have greater control over how their data is collected and used. However, ambiguities in the laws, such as the scope of profiling opt-outs, may require further clarification from regulators.
Innovations and Adaptations in the Advertising Ecosystem
Despite the mounting pressures, targeted advertising is far from obsolete. Companies are innovating to adapt to these changes, exploring alternative approaches to deliver personalised ads while respecting privacy.
Google, for instance, is piloting a new advertising model that moves away from individual tracking. Its “Privacy Sandbox” initiative includes tools like Federated Learning of Cohorts (FLoC), which groups users with similar interests into cohorts without identifying them individually. While FLoC faced criticism and has been replaced by “Topics API,” the general approach signifies a shift toward aggregate-level targeting.
Similarly, Adobe has introduced a software platform enabling businesses to harness first-party data collected through Adobe products for targeted advertising. By leveraging their own customer data, companies can deliver personalised ads without relying on third-party cookies.
These adaptations reflect a broader trend: advertisers are shifting from third-party data to first-party data strategies. This transition involves building direct relationships with consumers, collecting data through owned channels such as websites and apps, and using that data to craft targeted campaigns.
Opportunities and Challenges Ahead
The erosion of traditional tracking methods presents both challenges and opportunities for the advertising industry. On one hand, advertisers must navigate a more complex landscape, balancing privacy concerns with the need for effective targeting. On the other hand, these changes encourage innovation, fostering the development of privacy-preserving technologies and business models.
One significant challenge lies in ensuring compliance with evolving privacy laws. As more jurisdictions adopt stringent data protection frameworks, businesses must implement robust systems to manage consumer data, process opt-out requests, and ensure transparency.
Simultaneously, companies have the opportunity to rebuild trust with consumers. By adopting privacy-centric practices and providing clear value propositions, businesses can strengthen their relationships with customers. Transparency and accountability will be key differentiators in this new era of advertising.
Moreover, the shift toward first-party data collection aligns with broader industry trends emphasising customer loyalty and engagement. Companies that invest in creating compelling, personalised experiences based on direct interactions with consumers will be better positioned to thrive.
Conclusion
The online advertising industry stands at a crossroads, shaped by technological advancements and an evolving legal landscape. The decline of third-party cookies and the rise of privacy-centric practices signal a fundamental shift in how advertisers connect with consumers.
While these changes disrupt traditional models, they also open doors to innovation. By embracing new technologies and prioritising consumer trust, businesses can navigate this transition and seize opportunities in a privacy-first world.
As the digital advertising ecosystem continues to evolve, collaboration among industry stakeholders, regulators, and technologists will be essential. Together, they can chart a path forward that balances the needs of businesses with the rights and expectations of consumers, ensuring a sustainable future for the industry.
