The results indicate that, for hedonic products endorsed on SNSs, strong-tie endorsers are more effective than weak-tie endorsers, regardless of their expertise on the endorsed products; but for utilitarian products endorsed on SNSs, high-expertise endorsers, as compared to low-expertise endorsers, result in higher consumers' purchase intention, regardless of their tie strength with consumers. Based on these results, theoretical and practical implications were discussed, and suggestions for future research in social network advertising were also provided.
