Rather than simply looking at the target indicator, this lecture seems to be full of points to check which steps are checked in the process and how to make objective decisions. In particular, from the marketing side, it was a time to think about how to bring in users and at the same time how to make decisions through retention indicators. I also thought that I should study the GA target flow a little more and proceed with the campaign while looking closely at the intermediate steps to the goal! Thank you for the great lecture! :)
