We advise clients across the advertising life cycle, supporting them to maximise campaign efficiency, manage regulatory compliance, and grow dataset value in innovative and effective ways.

The AdTech industry has been the subject of regulatory attention for years in both the UK and the EU. Highlights include the UK ICO’s investigation into real time bidding (RTB), massive fines issued by the French CNIL in relation to the use of cookies and US-based website analytics tools, and the Belgian DPA’s compliance action against IAB Europe’s Transparency and Consent Framework, used by much of the industry across Europe. In the US, the Federal Trade Commission is actively seeking to understand how major social media and streaming platforms collect and use consumer data for advertising. We support clients active in this space as they navigate this myriad web of regulatory scrutiny, and adapt their business models to collect and monetise data in compliance with the evolving rules.

Linklaters have one of the longest-standing privacy practices in the world, and act on some of the largest and most high profile AdTech enforcement actions. Our privacy team also works closely with our Antitrust and Foreign Investment Group, reflecting the joint approach of privacy and competition regulators in this space (such as the ICO and CMA in the UK) and the tension between the protection of personal data and transparent, open markets. In addition, our deep expertise in data protection is integrated with technology and commercial contracts know-how, so we can give holistic and pragmatic solutions to clients operating within this highly regulated, fast-paced industry. Our footprint in context of AdTech is uniquely global, with real strength and privacy capability across the US, Asia and Europe, which allows us to provide seamless international support to our clients, because we know their businesses are truly global.

Clients benefit from our breadth of expertise, which includes advising:


on this portfolio of companies’ compliance with global data-related laws, including privacy impact assessments, tackling international data transfers, podcast distribution, AdTech transactions, and supporting on the launch of “SmartAudio,” which provides brands with more effective ways to reach their audiences.
