Marketing roles played by artificial intelligence (AI) have dramatically changed over the past ten years and have grown to become part of maximizing customer experience as well as business operations. AI-based chatbots and algorithms are increasingly used for any form of customer interaction, answering queries or recommending products. This has enabled business firms to provide faster, more efficient, and more customized experiences for consumers, therefore enhancing greater engagement with satisfaction. However, as AI surfaces as the central player, establishing consumer trust is necessary. Consumer trust in the AI-driven marketing system can be influenced by a few issues concerning the competence of the AI in accuracy and efficiency in performing tasks, the transparency of AI operations, and the reliability of the outcomes generated. The trust further relies on security and privacy arrangements to protect user data with the rising digital ambit. The paper encompasses these two aspects and demonstrates how firms may build and maintain trust through ethical action, responsible AI use, and open operations. Finally, this paper examines the ethics surrounding the use of AI in marketing issues like algorithmic bias and fairness. Through such proactive management, firms can ensure there is no dilution of trust but, instead, are able to hold stronger relationships with the consumers. The future trends that further impact the general amount of consumer trust in AI-based systems will be emotional AI, explainable AI, and the governance of AI practices. From all this, it’s evident that brands must continue to innovate within ethical boundaries that preserve consumer trust and loyalty.
