As a junior marketer who is already executing advertisements, I took the course because I wanted to improve my advertising capabilities. Although I already knew the basics while working, there were many things I learned or understood in the course. In particular, I had a lot to think about because the explanation of targeting and a/b testing, which I had only vaguely thought about, and the insight of the knowledge sharer were shared!! I think this is a very good course for junior marketers or those who want to try marketing for the first time to build a foundation or broaden their thinking.
