Finally, after data analysis, the conceptual model of the research was fitted using the structural equation model and PLS3 software. Results: The conceptual model of the research was fitted using various indicators and the results showed that the model has appropriate quality and acceptable validity. Quantitatively, findings indicated that brand confidence of 0.228 had a significant effect on brand advocacy, but emotional commitment and loyalty with a coefficient of 0.049 and 0.007, respectively, had no significant effect on brand advocacy.
