This study assesses the impact of the CBBE antecedent instrument of cognitive
(internal consumer) and marketing (external) factors on the formation of brand equity through
brand personality in e-commerce companies. The study was conducted with a quantitative

have frequently made purchases through e-commerce in Indonesia which are then processed
using SPSS 25. The results of the study indicate that cognitive antecedents have a positive

fully mediate marketing factors on brand equity. This research provides the latest
contribution to the development of a digital industry strategy to build brand equity in ecommerce companies, especially through brand personality
