<b>Duplicating your winner usually backfires. Here's when it doesn't.</b>
3pm, winner maxed, I duped it 5x to scale → all 5 cannibalized the original, CPA tripled across the board. Auction overlap ate me alive. Now I dupe ONLY into a new audience or new placement, never the same targeting. One winner, one auction → respect it. Vertical scale (budget) beats horizontal (copies) nine times out of ten.
