#115 The Measurement Mistakes Costing Brands Millions | Cormac Jonas

In this episode of Always Be Testing, host Tye DeGrange is joined by Cormac Jonas, CEO and Founder of The Jonas Agency, for a deep dive into what’s actually broken in modern performance marketing. With years of experience across affiliate, paid media, and creator-led growth, Cormac brings a sharp perspective on why so many brands are optimizing campaigns while ignoring the bigger problem: flawed measurement.The conversation unpacks how misattribution, last-click bias, and platform incentives distort ROI, using the recent Honey browser extension controversy as a real-world example of how value gets misassigned across channels. They explore why TikTok and YouTube reshaped high-intent demand, how AI, CTV, and programmatic traffic are inflating “performance” metrics, and why owning an audience now matters more than owning traffic. This episode is a candid look at where affiliate and performance marketing are heading — and what brands need to fix before scaling spend.
