Account consolidation vs segmentation: fewer ad sets, more signal

Across 40 accounts, 90d:
— Segmented (8+ ad sets): each splits the 50-conv learning threshold, 60% stay stuck in learning
— Consolidated (2–3 ad sets): clear learning fast, CPA 18% lower
The old playbook of granular ad sets fights Meta's learning math — every split dilutes the signal the algorithm needs.
Read: post-2021, consolidation beats segmentation. Merge ad sets until each clears 50 weekly conversions, then stop splitting.
