This paper aims to examine the antecedents of brand passion and brand community commitment, namely, self-congruity and athlete attraction, as well as their effects on online brand advocacy in online brand communities.
The sample comprises members of a Facebook football fan club brand community. An online survey measuring athlete-level factors, team-level factors and online brand advocacy provides data to test the conceptual framework using structural equation modeling with partial least squares (PLS-SEM).
The findings of this paper support the positive spillover effect from athlete subbrand to team brand advocacy, as self-congruity exerted positive effects on brand passion and brand community commitment, while athlete attraction influenced brand community commitment, leading to online brand advocacy.
The findings validate the dimensions of online brand advocacy and advance research on sports brand hierarchy in brand architecture by establishing the transference effect from athlete to the team brand.
To effectively manage their brands online, brand managers need to pay attention to the powerful and multifaceted tool of online brand advocacy. Brand managers can capitalize on their active advocates by working closely with them to co-create uplifting and authentic brand stories that are worthwhile for sharing, especially in times of crisis.
Building on the developmental trajectory of brand love and vicarious brand experience, the findings verify the directionality of the spillover effect and offer insights into the development of brand advocacy across different brand levels.
