Today, we are talking about a massive misconception in the Amazon advertising world: the hyper-prioritization of Total ACoS.

First things first, I will always argue it should be called ACOTS (Ad Cost of Total Sales), but terminology aside, using this metric purely as a PPC goal is fundamentally broken.

The biggest flaw we cover in this episode is how product-level Total ACoS ruins your math, specifically because of Other SKU Sales. When you look at paid sales for a product ad, you're actually looking at sales generated for every SKU in your catalog.

Instead of making misinformed cuts, we need to think full-funnel. In this episode, I break down exactly how to approach your Amazon PPC strategy for 2026. We discuss why you must track organic visibility alongside PPC visibility, how to use your Search Query Performance dashboard to monitor market share, and why you should be evaluating your Total ACoS at the Parent-Child family level using the Purchased Product Report.

We’ll see you in The PPC Den!
