This document summarizes a research study that examined the impact of social media marketing activities on consumer purchase intention, specifically looking at Facebook live streaming. The study found that all social media marketing activity variables, including perceived trust, electronic word of mouth, entertainment, and interactivity, had a significant impact on purchase intention. Perceived trust was found to be the best predictor of purchase intention, followed by electronic word of mouth, entertainment, and interactivity. The findings suggest that while live streaming provides engagement through entertainment and interactivity, trust and word-of-mouth are the top influencing factors for consumer purchase intention.
