Social media has become one of the main ways firms reach, persuade and keep customers. This study asks how social media marketing (SMM) shapes consumer buying behaviour. A structured questionnaire was given to 200 social media users, covering four aspects of SMM exposure (engagement with brand content, influencer credibility, peer reviews or electronic word-of-mouth, and brand trust) along with a purchase behaviour construct. Every multi-item scale was reliable, with Cronbach's alpha between 0.755 and 0.787. A chi-square test showed that age group and purchase action after SMM exposure are significantly associated, χ²(3, N = 200) = 11.28, p = .010, Cramér's V = 0.24, with younger respondents the most likely to have bought something. A one-way ANOVA found that purchase behaviour differed by the platform people used most, F(3, 196) = 3.42, p = .018, η² = 0.050, and Tukey's HSD showed that Instagram users scored higher than WhatsApp/Other users. In the multiple regression, the four SMM factors together explained 11.1% of the variance in purchase behaviour, F(4, 195) = 6.09, p < .001. Influencer credibility (β = .246), peer reviews (β = .162) and brand trust (β = .149) all had significant positive effects, while engagement with brand content did not (β = .088, p = .196). In short, credibility and social proof count for more than simple exposure. The paper recommends that marketers invest in credible influencer partnerships, genuine customer reviews and trust-building.
KEYWORDS
This study examined how social media marketing influences consumer buying behaviour, using chi-square, ANOVA and multiple regression. Purchase action varies with age, and purchase behaviour varies with platform. Three of the four SMM factors (influencer credibility, peer reviews and brand trust) significantly predict purchase behaviour, while engagement alone does not. Taken together, the results suggest that being believed counts for more than being seen. Firms that build credibility, encourage authentic peer voices and earn trust are in a better position to turn social media attention into purchases.
