This study comprehensively examines the profound transformation that artificial intelligence (AI) has brought to marketing in the rapidly advancing era of digitalization. It emphasizes that AI is not merely a technological tool but a strategic decision-making instrument for brands, particularly in redefining the relationship between consumers and companies through personalization, data analytics, and targeting processes in social media marketing. The study highlights that consumers’ perceptions of value, trust, and loyalty have been reshaped by this transformation; while personalized experiences enhance satisfaction, the lack of ethical standards and transparency may lead to trust issues. With the rise of AI-generated content and virtual influencers, the nature of social interaction has also evolved, positioning brands not only as providers of products or services but also as designers of experiences and creators of emotional connections. Moreover, the study argues that for AI to ensure sustainable success in marketing, technological innovation must be balanced with ethical principles, data privacy, and transparency. In conclusion, AI is positioned not merely as a tool for automation but as a transformative paradigm that redefines marketing by reconnecting consumers and brands on an emotional, cognitive, and ethical level, with trust at its core.
