The Product-Level TACoS Flaw: How "Other SKU Sales" Are Ruining Your Math

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!🦡 Highlights ​​0:00 - The hyper-prioritization of Total ACoS 1:58 - The evolution of Amazon PPC goals (2012 vs. today)3:35 - Why TACoS is a broken metric (and why we should call it ACOTS!) 4:32 - Why a lower TACoS can actually mean LESS profit 8:50 - The absolute worst (but easiest) way to "fix" your ACoS 10:22 - Why product-level TACoS is mathematically broken 12:01 - The "Paid Sales" illusion and how ads actually work 13:25 - How "Other SKU Sales" are completely ruining your product-level data 15:30 - Real account example: What happens when 30% of sales go to other SKUs 17:20 - The Fix, Step 1: Thinking full-funnel & tracking organic rank 18:10 - The Fix, Step 2: Using Search Query Performance (Search Trends) 20:10 - What to do if your ACoS is actually too high 22:01 - The 2026 Solution: Grouping Total ACoS by Parent-Child Families🦡 Resources & Links🦡 GET AD BADGER ➡️ Find Michael Erickson Facchin — Ad Badger’s CEO and soul, PPC whisperer, and your go-to guide through the wild world of Amazon advertisingWhat is the SKU Economics Report and How It Boosts Amazon Ads?How TACoS Relates to Your Ad PerformanceWhen Higher Total ACOS Means More Profit📚 Unlock our FREE comprehensive Amazon Marketing PlaybookSubscribe to our newsletterTransform your workflow with our comprehensive Amazon Advertising checklistReview all our show notes-Host and Executive Producer: Michael Erickson FacchinSenior Producer: Nancy Lili GonzalezPodcast Coordinator & Graphic Designer: Sofiia PodashVideo and Audio Editor: Pedro Moreno
