You duped your winner 5x in one night and it died?

You duped your winner 5x in one night and it died?

Classic. You stacked duplicates (copies of the same ad set) on top of each other before any of them exited learning.

Meta read them as 5 competing bidders for the same audience. You bid against yourself, CPMs spiked, ROAS tanked.

The fix:

— Dupe ONE at a time, 24-48h apart
— Each new copy gets its own day to find footing
— Watch auction overlap in the delivery breakdown (it'll literally tell you you're cannibalizing)

Duping isn't free volume. It's a new auction entrant every time.

Try it on ONE winner this week. Resist the urge to copy-paste a wall of them.
