Another one! Besides being certified in Google Tag Manager by Google I have just finished this one by Measure School and the great Julian Juenemann. Had tons of fun learning with him. What's great about his materials is that he has many assignments throughout the whole course forcing you to actually learn by doing. Plus he's always available if you are stuck! Check him out if you haven't yet but if you are in the analytics industry I seriously doubt if you haven't heard of him. Check out his super helpful YouTube channel, for analytics tricks-and-tips and for more info about the GTM course or his other Google Analytics stuff just click here.
