We pulled a report for a brand recently. Established product, two years on Amazon, healthy ACoS across every campaign. What we found underneath it was that their organic rank had dropped four positions on their main keyword over six months. The revenue they were attributing to their ads? A significant chunk of it was sales they used to get for free. They weren't scaling. They were paying for ground they'd already owned.

In this episode, I break down why ACoS alone is the wrong target, what TACoS actually tells you that ACoS can't, and how to read your own numbers to figure out which side of this problem you're on. A brand with 18% ACoS and 22% TACoS is in trouble. That gap is too small. The same brand at 18% ACoS and 9% TACoS is healthy. ACoS can't tell them apart. TACoS can.

I walk through TACoS benchmarks by product stage: 25-40% at launch, 15-25% in growth, 8-15% at maturity. I cover how organic cannibalization works, where you're bidding aggressively on keywords you already rank for organically, your ad captures the click, your organic conversion rate drops, and over six months your rank drifts down one position at a time with no obvious inflection point. ACoS still looks fine. TACoS is creeping up. And you have no idea it's happening.

There's a two-minute calculation using your existing reports that tells you immediately whether your ad strategy is building your business or just replacing it. I show you exactly how to run it and where to redirect budget when ads are competing with your own organic listings.
