The development of information and communication technology has significantly transformed consumer behavior, particularly in the process of searching for information prior to making a purchase. One rapidly growing phenomenon is Electronic Word-of-Mouth (eWOM), which refers to informal communication among consumers through digital platforms such as social media, online forums, and product review websites. eWOM is considered more credible than traditional advertising because it originates from real user experiences. This study aims to analyze the impact of eWOM on consumer purchase intention with trust as a mediating variable. A quantitative approach with a cross-sectional survey design was employed, involving active users of digital platforms who accessed product reviews before purchasing. Data were collected via online questionnaires and analyzed using multiple regression and mediation testing (Baron and Kenny approach with Sobel test). The findings reveal that eWOM has a positive and significant effect on consumer trust (β = 0.72) and directly influences purchase intention (β = 0.31). Trust demonstrates a stronger effect on purchase intention (β = 0.56) and serves as a significant mediator in the relationship between eWOM and purchase intention (indirect effect = 0.40). These results highlight that the quality, credibility, and consistency of eWOM information are crucial in building consumer trust, which subsequently enhances purchase intention. Theoretically, this study enriches digital marketing literature, while practically it provides implications for companies to manage online reviews transparently and foster consumer trust to drive purchasing decisions.

This study aims to analyze the influence of Online Advertising on purchasing decisions for Skintific products by considering the mediating role of Trust and Social Media Engagement. Skintific, as a digital-native skincare brand, actively utilizes digital marketing strategies through various social media platforms such as Instagram, Tiktok, or e-commerce like Shopee to increase consumer appeal, especially in Malang City. This study uses a quantitative approach with the Partial Least Squares Structual Equation Modeling (PLS-SEM) method to test the relationship between variables. The sample was obtained through a purposive sampling technique with 114 respondents who are active consumers of Skintific. The results of this study indicate that Online Advertising has a significant effect on purchasing decisions, both directly and through the mediation of Trust and Social Media Engagement. Theoretically, this study extends the application of the Theory of Reasoned Action (TRA) in explaining the formation of attitudes and subjective norms of consumers towards digital advertising, as well as the Technology Acceptance Model (TAM) which shows how perceived ease and usefulness of digital advertising content affect user engagement. Customer Trust Theory in E-Commerce is used to explain how trust is formed in online transactions, while Relationship Marketing Theory emphasizes the importance of long-term interactions between brands and consumers. The Theory of Planned Behavior (TPB) expands this framework by adding the construct of behavioral control, which explains how consumers' perceptions of ease and barriers contribute to purchasing decisions. Social Influence Theory is used to understand the influence of social norms and online community opinions on purchase intentions, and Uses and Gratifications Theory (UGT) to examine consumer motivations in accessing and interacting with digital content based on information needs, affection, and self-identity. This research provides theoretical contributions in strengthening the relevance of integrating several consumer behavior theories in a digital context.

This study aims to analyze the effect of green marketing on purchase decision with brand image as a mediating variable among consumers of Satvika Bhoga in Denpasar. The research is grounded in the increasing consumer awareness of environmental issues, which has not yet been fully reflected in consistent purchasing behavior toward environmentally friendly products.

The analysis was conducted using path analysis and the Sobel test to assess both direct and indirect relationships among variables. These methods allowed the researchers to examine not only the magnitude of influence but also the mediating role of brand image in shaping purchase decisions. The results indicate that green marketing has a positive and significant effect on purchase decision and significantly strengthens Satvika Bhoga’s brand image as an environmentally conscious brand. Furthermore, brand image was found to have a strong and statistically significant influence on purchase decision, confirming its role as a partial mediator. This implies that green marketing efforts, such as eco-friendly packaging, sustainable sourcing, and environmental messaging, not only influence consumer decisions directly but also enhance the overall brand perception, which in turn further motivates consumers to make purchases. Thus, businesses aiming to improve eco-product sales should prioritize consistent green marketing strategies that reinforce a trustworthy and environmentally responsible brand image.
