Item The Influence of Facebook User-Generated Content on E-Brand Loyalty with the Mediating Effect of Perceived Brand Authenticity with Special Reference to the Cosmetics Industry in Sri Lanka(Department of Marketing Management, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka., 2025) Malshani, L. L. D. T.; Subasinghe, S. M. A. N. M.User-generated content has become a more discussable factor in digital marketing. Businesses have taken UGC as a key consideration as it may affect the business in a positive way as well as in a negative way. Marketers are looking for strategies to mitigate the negative effects of UGC while improving the positive effects of UGC. To have long-term relationships, loyalty businesses must make their customers feel connected with their brands while providing them with authentic products and services. Present study studies the influence of Facebook user-generated content on e-brand loyalty while concerning the mediating of perceived brand authenticity. The main objective of the study is to analyze the influence of Facebook user-generated content on e-brand loyalty in the cosmetics industry in Sri Lanka. This study adopts an explanatory research design, guided by the positivist research philosophy. A deductive approach is employed, utilizing quantitative data. The research follows a cross-sectional design, with data collected through an online questionnaire. Primary data was obtained from 387 respondents residing in the Western Province of Sri Lanka. A non-probability sampling method, incorporating both convenience and judgmental sampling techniques, was used to construct the study’s sampling framework. Data analysis was conducted using IBM SPSS version 30, employing descriptive statistics, frequency analysis, correlation analysis, and regression analysis. Few studies have focused on the relationships between UGC and e-brand loyalty or considered the mediating role of PBA. Most studies are focused on industries such as fashion; therefore, the cosmetics industry, especially in Sri Lanka, remains highly under-researched. This research, therefore, tries to fill this gap by examining how Facebook UGC affects the e-brand loyalty of Sri Lanka's cosmetics industry, with PBA as a mediating factor. This study established that UGC about Facebook was important in increasing both e-brand loyalty and perceived brand authenticity of cosmetics in Sri Lanka. UGC has been seen to affect the consumers' perception of the authenticity of a brand and directly lead a consumer to be loyal to the brand. On the contrary, perceived brand authenticity was a very important driver of e-brand loyalty; hence, it is of strategic importance to brands. The analysis also confirmed that perceived brand authenticity mediates the relationship between UGC and e-brand loyalty, serving as a kind of bridge that will ameliorate the connection between engaging and relatable content on one side and customer loyalty on the other. The limited availability of industry-specific reports in Sri Lanka was a challenge. It also focused on the Western Province only because of time constraints and the ease with which data is available, which may affect generalization across other regions or contexts. This dependence on quantitative approaches ruled out qualitative information. The structure of the study also had a general relationship without considering the sub-constructs; this also opens an avenue for further research at a more detailed level. It confirms that dimensions of UCG, such as trustworthiness, transparency, and quality, are of great relevance. It calls on marketers to encourage consumers to create favorable content on some form of stimulus, such as through reductions. Managers have to respond to negative responses constructively, build authentic brand experiences, and ensure communications are being sent across consistently. Future research gaps have been identified to study e-brand loyalty in other industries, test the relationships of sub-constructs, and adopt qualitative methods to gain more detailed insights. Furthermore, studying UGC beyond geographical constraints and investigating specific UGC types may yield more insightful information to help marketers use UGC properly to foster brand growth.Item Impact of Social Media Macro-Influencer Authenticity on Purchase Intention for Fast Food Brands in Sri Lanka Among Gen Z: The Mediating Effect of Brand Credibility(Department of Marketing Management, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka., 2025) Lakshani, L. H. S.; Subasinghe, S. M. A. N. M.This research explores the impact of social media macro-influencer authenticity on purchase intention for fast food brands in Sri Lanka among Gen Z: the mediating effect of brand credibility. This demographic, characterized by its digital savviness and preference for authenticity, presents unique challenges and opportunities for marketers. The study addresses a critical gap in literature by investigating how key factors of influencer authenticity trustworthiness, expertise, attractiveness, and similarity shape purchase intentions. It also examines the role of brand credibility in this dynamic. Fast-food brands face significant competition and need innovative marketing strategies, particularly in urban regions where consumer preferences are rapidly evolving. The research situates itself within the existing literature on influencer marketing and extends it by contextualizing findings within the socio-cultural and economic environment of Sri Lanka, providing actionable insights for brands seeking to optimize their marketing strategies for Generation Z. and 403 members of Generation Z who actively follow fast-food influencers on social media sites like Facebook, Instagram, and TikTok were given a structured online survey as part of the study's quantitative research approach. Statistical methods such as the Cronbach's alpha, KMO, and Bartlett tests were used to make sure the data was reliable and valid. Regression analysis and mediation analysis were used in the data analysis to ascertain the direct influence of influencer authenticity characteristics on purchase intention and the involvement of brand credibility in this connection, respectively. The Source Credibility Model serves as the theoretical foundation for the study, highlighting the crucial role that influencers' perceived sincerity plays in influencing customer behavior. Additionally, the analysis takes demographic and cultural factors into account, placing the results in the larger framework of digital marketing. The results show that purchase intention is significantly positively impacted by macro-influencer authenticity, with likeness and beauty being the most important characteristics, followed by knowledge and trustworthiness. This relationship is further amplified by the mediating function of brand credibility, which shows that real influencers not only directly affect customer choices but also raise the perceived legitimacy of the companies they support. These findings are consistent with earlier studies that highlight the value of relevant and trustworthy influencers in building engagement and trust, especially among Generation Z. The Western Province was the study's primary emphasis, which restricts the findings' applicability to other parts of Sri Lanka where cultural and economic circumstances can be different. Furthermore, using self-reported information gathered via online questionnaires raises the possibility of response biases. Future research could address these. By using a variety of geographic samples, performing in-person or offline interviews, and investigating the joint roles of macro and micro-influencers, future study could overcome these constraints. This study has both theoretical and practical ramifications. The study theoretically adds to the expanding corpus of research on influencer marketing by emphasizing the relationship between customer behavior, brand credibility, and influencer authenticity. By placing the Source Credibility Model in the context of an emerging economy's digital marketing environment, it expands upon it. In practice, the results give fast-food companies a foundation for improving marketing efficacy. Businesses can increase trust and create stronger bonds with their target audience by collaborating with influencers who exhibit authenticity and share brand values. The study emphasizes how crucial it is to incorporate culturally appropriate and open marketing techniques, making use of the special qualities of macro influencers to successfully interact with Generation Z. For marketers navigating Sri Lanka's fiercely competitive and technologically advanced fast-food business, these insights are priceless.
