PurposeAdopting the theory of parasocial interaction (PSI) and schema theory, this study proposes that a brand’s personalized response and brand familiarity on a corporate blog will lead to higher perceived brand similarity, credibility and blog recommendation intention.Design/methodology/approachA 2 (brand familiarity: high, low) × 3 (brand responses: none, automated and personal) experimental design was developed to test the hypothesized relationships. A total of 474 qualified data were collected using an online survey. ANOVA was utilized to test the research hypotheses.FindingsStudy results revealed that personalized messages lead to stronger perceived brand similarity, credibility and blog recommendation intention than those exposed to automated and no response. Brand familiarity also significantly influenced perceived brand similarity, brand credibility and blog recommendation intention. Further, the study analysis revealed an interesting interaction effect between brand awareness and brand response on recommendation intention.Originality/valueThe study provides meaningful implications and suggestions for the effective corporate blogging strategy to influence consumers’ attitudes and image toward brands and establish strong brand equity and relationships with customers.
