Most of my experience is smaller Meta/Google campaigns for clients and freelance. Lately I keep hearing this narrative that the big divide between small and large-budget PPC is tracking infrastructure, attribution models, conversion APIs, all that jazz.
Honestly? I think it's a cop-out. The real gap is creative velocity and decision-making speed. I've seen agencies with perfect server-side tracking still drown because they couldn't kill a failing ad fast enough or because their creative testing was a joke.
Sure, once you cross a certain spend threshold, messy data hurts more. But the teams that actually scale well aren't the ones with the slickest CAPI setup - they're the ones who've automated the boring parts and left room for strategic bets.
So when people point me to John Loomer for attribution or Dara Denney for creative, I nod politely. But the truth? Most of that stuff is table stakes now. The edge comes from understanding when to ignore the data and trust your gut on audience angles.
What teams do you see genuinely nailing performance - not just tracking hygiene? I want names of shops that prove creative drives the bus, not back-end infrastructure.
