Hello , guys! How are you doing ? This class finally will come to the end! So sad... By the way , I ’ m going to talk about what I ’ ve learned from this class while looking back on the class. First , social media marketing can be the most cost-efficient part of an advertising strategy. Second , social media makes me know the thoughts and needs of my consumers by monitoring their activity. Third , scheduling and analyzing my posts can drivd the most traffic and engagement. Finally , I have to choose interesting topics that is attractive for audiences. I could study a lot of things about SMM through this class , and everything will be helpful for me in the future. I want to use advantages of SMM properly . Thank you for everyone read my articles and commented that. And , I appreciate for the professor taught us a lot of things!
