Background: Corporate Social Responsibility as a Marketing Strategy for Community Trust Building has practical relevance for communityfacing organizations because visible activity does not necessarily translate into durable organizational or stakeholder outcomes. In community trust building, managers must coordinate environmental and social impacts, claims, commitments, material topics, stakeholder feedback, and corrective action while responding to expectations from organizations, local communities, employees, suppliers, regulators, and civil-society groups. A program may expand reach or participation and still underperform when responsibilities are unclear, information is fragmented, or symbolic consultation. Aims: This article develops a capability-based framework explaining how corporate social responsibility as a marketing strategy may contribute to trust, credibility, and relationship stability. It distinguishes simple activity from coordinated capability and identifies boundary conditions that can weaken otherwise positive relationships. Research Method: The paper uses an integrative conceptual review of established literature relevant to the focal domain, organizational capabilities, stakeholder relationships, and learning. It does not claim primary survey, interview, experimental, or transaction data. Results and Conclusion: The synthesis identifies four mutually dependent mechanisms: impact and claim relevance, evidence and transparency, stakeholder dialogue, and follow-through and learning. Their value depends on transparent governance, usable information, proportionate participation requirements, and a review process that converts exceptions into improvement. The article argues that higher activity alone is an inadequate indicator of success because benefits can coexist with hidden workload, exclusion, dependency, or weakened trust. Contribution: The article contributes a diagnostic framework, linked performance indicators, six propositions for empirical testing, and a fivestage implementation pathway that can be used in resource-constrained community organizations.
