Duplicate the winner vs raise its budget — they are NOT the same move

Duplicate the winner vs raise its budget — they are NOT the same move
2pm, adset's printing, you want more. Two roads:
— Raise budget on the live adset → keeps learnings, but +20% a day max or you reset the algo and tank it.
— Duplicate into a new adset → fresh learning phase, fresh volatility, but you can stack 3-4 copies in parallel.
Dupes win when you're scaling fast and one adset caps out on audience. Budget-bumps win when stability matters more than speed.
Stop doing both at 3am and wondering why CPA exploded.
