What advice would you give yourself if you were a beginner again? Where would you put most of your energy and focus?Your plan can look excellent on paper, and it does look solid, but Google Ads BH is a complex matter that gets updated daily. You will always face challenges no matter what. I wasted alot of money trying to get Gambling Ads running, until it finally clicked and then i was able to scale, but even then, challenges happen daily, but with enough experience and a good team (And money) its easy to solve.
Good luck to you!
