The integration of artificial intelligence (AI) into marketing not only presents significant opportunities for value creation but also introduces critical ethical challenges related to data overreach, algorithmic bias, and opacity. To navigate this complex landscape, the concept of Corporate Digital Responsibility (CDR) provides a vital framework for firms. This article defines CDR as the principles guiding a firm’s ethical, fair, and protective use of data and technology within its digital ecosystem, distinguishing it from traditional Corporate Social Responsibility (CSR) by its specific focus on the digital realm. Drawing on the lifecycles of technology and data, this article explores the challenges organizations face in balancing personalization with privacy and the risk of digital manipulation. The “CDR calculus” is discussed as a model for understanding the trade-offs between adhering to ethical principles and pursuing business objectives, such as profitability and efficiency. The article also discusses how to implement effective CDR practices through organizational culture, governance, and a proactive approach to regulation, which can help bridge the consumer “legitimacy gap” and build long-term trust. The paper concludes that CDR is a strategic imperative for businesses to foster a more responsible and sustainable digital future.
