In this regard, the current research seeks to investigate the influence of the factors of Data Privacy Concern and Perceived Value on customer engagement in personalized digital marketing, viewed from the perspective of social media marketing in Nigeria.

In carrying out this research, the approach used was a Qualitative Integrative Literature Review of twenty academic literature sources published from 2020 to 2025. Thematic content analysis was done using Microsoft Excel 2021 based on the theories of Privacy Calculus Theory and Social Exchange Theory.
