I do not recommend the lecture... First of all, the GA - Google Tag Manager, etc. linkage screens are so different that it is difficult to follow the lecture smoothly. They said that they would update the relevant part by April, but the same content is still posted as of early June. And they recommended purchasing Aimweb to use it as a practice page, so I paid the fee, but The site is only used for the initial linkage practice, and all the practice is done on the Baeumkok site for the in-depth part of the latter half of the lecture. The problem is that the site is completely inaccessible... I left a question in the community directly saying that it is difficult to use the site and asked for a solution, but the AI gave a vague answer and did not provide any solution. As you know, there is a big difference between actually experiencing the linkage process yourself and just seeing it with your eyes. If this is the case, I don't know why they recommended purchasing Aimweb in the first place, and I don't understand why they are not taking any action even though they haven't solved the access issue on the site. And lastly, the lecture materials cannot be downloaded. It said that you can download by pressing the cloud-shaped download button at the top of the lecture dashboard, but I can't find that button at all. I don't know if the configuration provided by applying through the lecture company is different, but in any case, it was impossible to download materials such as event taxonomy separately. I think the lecture content itself is helpful because it explains with examples. You can learn how to set up Google Tag Manager for event tracking and track it on GA. However, even though it is a paid lecture, I think the quality that should be maintained is very lacking... If I take a GA lecture next time, I think I will take the latest lecture even if the curriculum is a little different from what I want.
