It is informative and fun to listen to, as it contains only the 'key' that can be applied directly to practice. This is a lecture that I would like to recommend to juniors who want to advertise on Facebook/Instagram but are at a loss as to how to proceed. I was able to gain practical knowledge about Facebook's advertising principles and ad settings, and I was able to gain insight into indicators that must be checked and how to increase conversion performance. In particular, I liked the detailed explanation of the concept of pixels that I had vaguely known, and it was easier to understand because it showed various real examples. Thank you for making a great lecture :)
