Learning phase = the window before Meta's delivery model stabilizes on an ad set.

Exit-velocity study, 41 accounts:
— Ad sets that exited learning: median CPA $31
— Stuck in 'Learning Limited': median CPA $40 ▲
— Most common cause: optimizing for a conversion event too deep in the funnel for the budget
— Fix that hit fastest: optimize one step up the funnel until volume clears 50/wk, then move down

Underfeeding an event is more expensive than a 'worse' but well-fed one.

Read: pick the deepest event your budget can feed 50/week, not the deepest event you want.
