The only thing that made sense for me was letting an automated system shift budget to what truly delivers. I used to overfund campaigns that looked good in the ad manager but had zero real revenue. Then I came across ad waste management while reading a Reddit thread about wasted ad spend. What caught my attention was how it automatically reduces spend on underperforming campaigns and reallocates it based on actual tracked conversions. Since I set it up, my ad budget has started to work like it should — focusing only on results that matter.
