Purpose: With the expansion of digital technologies and the growing volume of marketing data, artificial intelligence (AI) has become a key tool in marketing decision-making. Despite the considerable growth of research in this field, existing studies have often examined AI applications in marketing in a fragmented and isolated manner, resulting in the absence of a comprehensive and systematic perspective. Accordingly, the purpose of this study is to identify, classify, and explain the applications of artificial intelligence in marketing using a meta-synthesis approach and to propose an integrated framework of the main categories and dimensions in this domain.Method: This study is applied in terms of purpose and qualitative in nature, and it was conducted using a meta-synthesis methodology. To this end, a systematic search of reputable academic sources was performed, through which 87 selected scholarly articles published within a specified time period were identified. Following screening and quality appraisal, the articles were analyzed. Data analysis was carried out using thematic analysis, which ultimately resulted in the extraction of 309 final codes, 81 subcategories, and 18 main categories related to applications of artificial intelligence in marketing.Findings: The findings indicate that applications of artificial intelligence in marketing are multidimensional, data-driven, and integrative in nature. The most important AI-based marketing categories identified include product development, brand management, pricing, logistics, supply chain management, marketing channels, advertising, marketing campaign management, public relations, social media marketing, sustainable marketing, sales and sales forecasting, customer experience enhancement, customer relationship management, marketing strategies (STP), marketing research, consumer behavior analysis, and content creation. The results further show that artificial intelligence plays a significant role in improving the accuracy of marketing decisions, personalizing marketing activities, and optimizing marketing processes.Conclusion: Based on the results of the meta-synthesis, artificial intelligence has moved beyond a supportive analytical tool and has become an active agent within the marketing system. By transforming decision-making logic, strategy design, and customer interactions, this technology directs marketing toward intelligent, predictive, and adaptive models. The findings of this study provide a theoretical foundation for the development of intelligent marketing literature and offer practical guidance for managers seeking to effectively implement artificial intelligence in marketing activities.
