The Amazon PPC Budget Rollover ROAS Blind Spot
Season 2
Episode 76
Published 2 weeks, 1 day ago
Description
Most Amazon advertisers assume unspent daily budget automatically rolls over to help scale winning campaigns. But Amazon Portfolios actually treat budget pools differently than you think — and the rules changed late last year. Lucas and Luna break down the exact mechanism: how Portfolio budget rollover works, why it creates phantom ROAS when you're over-budget on one campaign and under on another, and the one thing sellers must check in their campaign manager before July 1 to avoid a sudden spend cliff. Includes a real example from a supplement brand that lost 40% of its impression share for two days because rollover logic burned their weekly cap. Plus, how to build a manual budget buffer that sidesteps the whole problem.
