The purpose of this research is to comprehend that if the difference between mobile promotions could really have a significant impact on teenagers’ brand evaluation and purchase intention. By means of Pearson correlation we can find out that there has a significant correlation between “mobile promotion,” “brand evaluation” and “purchase intention”.
