While online reviews are of paramount importance in brand evaluations and purchase decisions, the impact of a reviewer’s attractiveness is not well understood. To bridge that gap, this paper aims to explore how physical attractiveness cues through profile photos influence customers’ brand evaluations.
The first study assesses the impact of attractiveness and review valence on brand evaluations. The authors used an experimental design and tested the model with an ANCOVA. Study 2 examines the impact of attractiveness in the context of multiple reviews and tests attractiveness heuristic as the underlying mechanism.
The findings indicate that when an attractive (vs less-attractive) reviewer writes a positive review, brand evaluations are enhanced. However, such an effect does not occur with a negative review. With multiple reviews varying in valence, cognitive load activates the use of an attractiveness heuristic when a positive review is written by an attractive (vs less-attractive) reviewer, thus leading to enhanced brand evaluations.
These findings highlight the presence of the attractiveness halo effect in online reviews and offer important implications to social media marketers. While previous studies have largely focused on review characteristics (e.g. star ratings, strength of the argument, etc.), this study focuses on reviewer characteristics (i.e. attractiveness) and cognitive biases associated with online brand evaluations.
