“There is no point for you to try to interpret why an ad won or didn't win. What you should be interpreting is: when you get a win, or the win rate increases — the process worked. The output is irrelevant. That output is utterly random. Why that worked was utterly random.”

Stop trying to decode why a winning ad won — focus on the process that produced it

Seufert's most counterintuitive insight: with black-box platforms like Advantage+ and Pmax, the winning creative is selected by an algorithm you can't see, targeting an audience you don't know. Post-hoc rationalizations are noise. The only learnable signal is whether your creative-input process improved. Focus on raising the win rate, not reverse-engineering individual winners.
