Can consumer engagement on social media affect brand extension success? The case of luxury fashion brands and restaurants

This study aims to examine the effects of consumer engagement (CE) through social media (SM) on brand extension (BE) attitudes, extended brand loyalty, and parent brand loyalty. This study identified luxury BE strategies, particularly from luxury fashion brands to luxury restaurants. From an online survey involving 205 Korean women, we found that cognitive processing, affection, and the activation of CE positively influence attitudes toward BE. Furthermore, extension attitude positively influences both extended brand loyalty (luxury restaurant) and parent brand loyalty (luxury fashion brand), while extended brand loyalty positively influences luxury parent-brand loyalty. These findings support the associative network model and offer practical implications for marketing and branding managers for developing effective extension strategies.
