Digital marketing, as a dynamic and rapidly evolving field, closely follows the development of technique and technology and changes in market requirements, facing constant turbulence. This inherent dynamism brings forth certain challenges that digital marketing addresses with varying degrees of success and adaptability. In such an environment, it is not easy to effectively confront these challenges and overcome the limitations that arise in daily implementation. One potential solution to these limitations has been identified in modern and emerging technologies. This paper demonstrates the transformative impact of blockchain technology on digital marketing, and maps its contribution to both business and environmental sustainability, demonstrating how innovative blockchain-driven approaches can foster a more efficient, secure, and sustainable digital marketing ecosystem.
