The following research has been done to explain the key role of Customer Journey Mapping (CJM) in optimizing Social Media Marketing (SMM) strategy. This research has been developed due to the emerging dependency on social platforms for brands’ communications with their consumers. It addresses the need for a framework that synchronizes SMM efforts with the expectations and experiences of the customers. The problem statement can be interpreted as a lack of structured methodology that would ultimately integrate CJM into SMM practices, probably because of low levels of customer engagement and lower returns on investment. This approach includes systematic integration of the principles of CJM into the workflow of SMM, with the use of empathetic understanding of customers from their interactions over digital touchpoints. It therefore adopts a mixed-method research design, coupling qualitative analysis of customer sentiment with the tracking of quantitative metrics to assess the effectiveness of CJM on SMM. Preliminary results show significant rise in engagement and satisfaction. In addition, identification and mitigation of pain points or touchpoints would contribute to well-focused SMM interventions with insights into key issues. This study again underlines the CJM relevance instrumentally in ensuring better efficiency in conducting social media marketing. By embarking on a design-thinking inspired customer-centric tack, businesses rejuvenate their relationship toward a more affectionate audience touch, and hidden huge opportunities unlock through which brand impact and customer acquisition could be achieved while they navigate each passing day or time in existing digital space.
