Advertising Law Tool Kit - Fourteenth Edition - 2026

Venable / 39 38 / Venable Michael A. Signorelli masignorelli@Venable.com Interest-Based Advertising When engaging in IBA, consider these compliance fundamentals: • First parties should screen their vendors for DAA compliance. • First parties should check if a vendor is on the DAA Choice Page or AppChoices. • First parties should provide enhanced notice on web pages, on mobile applications, and in other connected device environments. • First parties should obtain consent for the collection or transfer of Precise Location Data by third parties. • Third parties should provide enhanced notice and offer an opt‑out for their IBA practices. • Third parties should obtain contractual assurances from first parties regarding consent for the collection, transfer, or use of Precise Location Data. To learn more about the DAA guidelines, visit youradchoices.com/principles. For additional considerations for targeted advertising under state consumer data privacy laws now in effect and those that will come into effect in 2026, please refer to the “Privacy and Data Security – State Privacy Laws” section on pages 62-65 . Data helps drive advertising efficiency. A particularly effective form of advertising is interest-based advertising (IBA). IBA is advertising based on analysis of user activity across nonaffiliated digital properties. It involves tracking activity across different websites and apps and across devices over time, making inferences about user interests based on that information, and delivering relevant advertising based on those inferred interests. The leading marketing and advertising trade associations developed a self-regulatory program, the Digital Advertising Alliance (DAA), to govern this form of advertising. The “DAA Self-Regulatory Principles” and related guidance and best practices (Principles) apply to website operators or app developers (first parties) and entities that collect data from first-party websites and apps for IBA purposes (third parties). The Principles require these parties to provide consumers with transparency and control regarding data collection and use for IBA on desktops, in the mobile space, on connected devices, and for cross- device linking.
