Maxed out one audience? I scaled sideways, not up

Maxed out one audience? I scaled sideways, not up

Broad audience capped — couldn't push past $1.5k/day without CPA blowing up. Vertical scaling (just raising budget) was dead.

So I went horizontal (new ad sets into new audiences with the same winning ad):
— Cloned the winning ad into 3 fresh ad sets: a lookalike 1%, a stacked-interest set, and a broad-with-exclusion set
— Each at $300 to start, same creative exactly
— Killed any that didn't clear $38 CPA by day 3

Lookalike + broad survived. Total went $1.5k to $2.7k/day, blended CPA $36.

Risk: audience overlap eats you alive — exclude your converters or you double-pay. Add ONE new audience at a time.
