$3k/day and scared to push? I split the budget two ways

$3k/day and scared to push? I split the budget two ways

Profitable at $3k/day, wanted $5k, but every vertical push (raising budget on existing sets) spiked CPA. Pure vertical was dead.

What actually got me there:
— Took the $2k of new budget and split it: half vertical (20%/48h ramps on winners), half horizontal (2 fresh audiences)
— Vertical added $700/day before it tapped
— Horizontal added $1,300/day across the 2 new audiences

Landed at $5k/day, blended CPA $37 vs $35 before — small bump, way more volume.

Risk: running both at once muddies which lever worked — track them separately or you won't know what to repeat. Don't blow all new budget on one lever. Split it.
