"There's a hard scaling cliff. Past it, accounts just break."

The "scaling cliff" (the spend level where CPA suddenly blows up) isn't a wall in the algorithm. It's usually YOU outrunning your creative and audience pool.

You didn't hit a Meta ceiling. You saturated your one good audience with your three good ads.

What's actually happening at the "cliff":

— Frequency creeps past 2.5-3 in your core audience
— Same 3 creatives, now fatigued
— You scaled spend but not INPUTS

Fix:

— Add fresh creative angles BEFORE you raise budget, not after
— Open new audiences (broad, lookalikes) to widen the pool
— Scale inputs and spend together, not spend alone

The cliff moves when you feed it. Test more creative before blaming the algo.
