Myth: Found a winner? Raise the budget and scale up.

No. Vertical scaling — cranking the daily cap on a working native campaign — drags in worse inventory as the algorithm reaches for volume it couldn't justify at the old bid. Your clean winner gets diluted by the junk it now has to buy to spend the money.

Horizontal scaling beats it on native almost every time:
— Duplicate the winner into new campaigns split by device, OS, or country.
— Launch the proven angle on a second network.
— Mine new top-sites from the winner's allowlist and isolate them.

Vertical scaling is one knob and a prayer. Horizontal scaling keeps each unit small enough that the algorithm stays honest. Everyone yanks the budget slider because it's the easy move. Then they wonder where the margin went. It went into the inventory you forced the bid to reach.
