Just hit a solid four weeks of running a Nutra offer at $500 daily spend. The jump from $50 wasnt linear at all. At around the $200 mark everything got weird. My CPA started creeping up even with new angles and placements. Felt like hitting a wall. The data tells a different story though. It wasn't just about more traffic or better creatives. The real shift came when I stopped optimizing for click volume and started filtering for user intent pre-click. That meant using audience layering that felt almost too restrictive but it cut my refund rate in half. My weekly net profit went from shaky to consistent by week three, but man those middle two weeks were rough. If you're trying to scale past that initial profitable zone, start looking at your post-conversion metrics like crazy. Are they staying for the upsell? What's the actual customer lifetime value according to the network dashboard not your tracker? That gap is where most of the hidden shaving lives AF.
