1% lookalike tapped out? I laddered up and held CPA

1% lookalike (audience Meta builds from your converters) was my best set but maxed at $1.2k/day — too small to scale further.

The ladder I built:
— Cloned the winner into a 1-3% lookalike and a 3-5%, same creative
— Excluded the 1% from the wider ones so no overlap
— $300 each, killed anything over $40 CPA by day 4

1-3% held at $36, 3-5% came in at $39 (acceptable). Total scaled $1.2k to $2.4k/day.

Risk: the wider you ladder, the closer lookalike gets to broad — past 5% it's basically interest-free targeting and quality drops. Don't skip exclusions or you double-pay for the same people. Add ONE rung at a time.
