Previous studies have found that emotional arousal and emotional valence are important for video ads to be shared. As marketers are exploring new strategies to increase their viral effectiveness in social media, there is a need to provide guidelines on how to elicit emotional engagement that can trigger advertising virality. Drawing on recent findings on the effects of discrete positive emotions, this research examines how specific positive emotions may influence viral sharing. An online experiment was conducted with millennial participants, employing real viral video ads, in order to observe the viral effects of two positive emotions, awe and affection. Awe and affection emotions experienced in relation to online ads may prompt viral sharing by activating specific types of sharing expressions that relate to expressing emotional connection and emotional generosity in social media. Managerial implications for applying positive emotions as triggers to the content of video ads in order to elicit virality in social media are included.

Companies consider social media‐based consumer engagement behaviors such as sharing, content creation, and reviews for brands as more valuable than “liking” or consuming brand content. Studies show that branded content shared or created by consumers on social media may drive more brand awareness and loyalty than “likes” (Adweek, 2013). Global companies are increasingly focusing their efforts on motivating consumer‐driven content creation (e.g., Coca‐Cola #shareacoke and Apple #ShotoniPhone; Sprout Index, 2018). However, marketing practitioners are only recently beginning to understand social media audiences who engage in such activities (Adweek, 2018). This study posits that human values can be used to identify and segment audiences for social media‐based valuable brand activities. Three online surveys were conducted with Facebook, Twitter, and Instagram users (ages 18–34) on Amazon Mechanical Turk (N = 491). The relationship between social media users' values and their reported social media activities was examined. Findings indicate that the human values examined (conservation, self‐enhancement, openness to change and self‐transcendence) are significant drivers of valuable brand‐related social media activities. Companies should address conservation‐driven users in order to elicit brand sharing and creation activities. Companies should target conservation‐driven users for sharing promotions, self‐enhancement‐driven users for sharing informational content and writing of product reviews, and openness to change‐driven users for user‐generated content. Bussinesses should further highlight their corporate social responsibility efforts as a negative relationship is found between users' self‐transcendence values and brand activities. Recommendations are provided on how brandscan address users' values in their social media marketing to motivate sharing of branded content and content creation.

Consumer-driven sharing and creation activities are valuable engagement activities as they help spread awareness and interaction for brands on social media. Loyal fans of brand pages are an important audience for brand-related social media engagement, as they are more likely to recommend and advocate for brands. However, little is known about what motivates loyal fans to engage in these valuable activities. This study takes a novel approach by examining self-expansion as a driver that prompts loyal fans to action. When brands offer self-expansive opportunities on their pages, in the form of new knowledge, new perspectives (e.g., awareness on social issues) and exciting experiences, fans may incorporate these in their sense of self (self-page inclusion) and reciprocate by investing their own resources to brand pages. A survey was conducted with 238 millennial users who have a favorite brand page on Instagram. The findings show that the more fans gain opportunities for self-expansion from their favorite pages, the more likely they are to share and create brand-related content. Brand page flow and self-page inclusion are also important drivers. Further, specific page experiences are identified that may enhance the effects of these drivers. Managerial implications are included on how to apply these findings to social media content strategy.
