Abstract

In the digital age, advertising has become deeply intertwined with personal data collection, processing and analysis. While targeted advertising offers benefits in terms of efficiency, relevance and business outcomes, it also raises substantial issues of data privacy, user autonomy, transparency and trust. This paper explores the concept of “responsible advertising” within the context of data privacy—asking how advertisers, platforms and regulators can align commercial imperatives with the ethical and legal rights of individuals. Drawing on extant literature from marketing, information systems, ethics and regulation, the study examines the mechanisms through which data is collected and used in advertising, the potential harms to individuals (e.g., loss of privacy, manipulation, discrimination), and the emerging governance frameworks and technical solutions designed to mitigate such risks. A mixed-method approach is used: first a secondary literature review to map the themes and trends, followed by qualitative interviews with advertising professionals and a survey of consumers (N = 350) regarding their perceptions of data use in advertising. Data analysis shows that greater transparency, giving users control over their data, and adopting privacy- preserving technologies are strongly correlated with higher trust and willingness to engage with personalised advertising. The findings suggest that responsible advertising is not simply about compliance with regulation—but about building long-term relationships of trust and fairness. The study concludes with recommendations for advertisers (e.g., adopt first-party data strategies, apply data minimisation, embed privacy by design), for regulators (e.g., strengthen enforcement, foster self-regulation, promote consumer literacy), and for future research (e.g., longitudinal studies of ad-trust over time, cross-cultural comparisons).
