so, tried bumping my campaigns from 50 to 500 a day last week, big mistake. option 1 was to just increase bids and budgets, thought it was simple. but it caused big drops in conversion quality and skyrocketed costs. option 2 was to split testing and optimize more, took longer but kept ROI stable. warning for anyone thinking of just maxing out spend overnight, it can backfire hard and kill your margins fast. not that deep but worth a heads up.
