This research paper will discuss how ethics and data privacy affect consumer confidence in AI-based marketing. As Artificial Intelligence is increasingly used in personalized advertising, suggestions, and automated customer contact, issues of data privacy, transparency, fairness, and ethical use of consumer data have become more prominent. The consumers do not have a clear understanding of how their personal information is gathered, processed, and transmitted and this may adversely impact their trust. The studies involve primary data gathered via questionnaires on 100 participants and statistical methods, including percentage analysis, Friedman ranking analysis, and average score analysis. The results indicate that the most significant aspects of creating consumer trust are data privacy, AI decision transparency, and ethical consumer data usage. The research concludes that transparent and ethical AI marketing is a key to increasing consumer confidence and promoting long-term brand relationships.
