Why Most E-Commerce Brands Are Measuring the Wrong Metrics (And Paying for It)

Most e-commerce brands are not losing because their product is bad or their ads are off. They are losing because they are measuring the wrong things and making decisions based on data that was never designed to tell the whole story. Mark Young is the founder of RYZE Agency, a PhD in functional medicine, a career educator, and one of the sharper strategic minds operating in direct-to-consumer and health and wellness e-commerce today. His five-book series, the E-Commerce Guide to the Galaxy, is built for founders who refuse to be taken advantage of by agencies again. ROAS is not a health metric. It is a signal. And the business owners who treat it as a target are handing their agencies a blueprint for smoke and mirrors. Mark Young, PhD has spent over a decade watching this play out in real time, walking into client relationships already contaminated by bad metrics, bad incentives, and the kind of blind trust that costs brands their momentum. He wrote five books on it because the problem is not a tactic problem, it's a literacy problem. In this conversation, Mark breaks down the specific metrics that actually drive e-commerce growth and explains why the ones most brands obsess over are actively working against them. Kayvon and Mark go deep on the Holy Trinity of Metrics: lifetime value, average order value, and new customer acquisition cost. They walk through how a business can rationally spend $300 to acquire a $100 customer, why blended MER matters more than account-level ROAS, how cross-channel attribution is being double-counted across Meta, Google, and email simultaneously, and how the "ready, fire, aim" wiring of most entrepreneurs is exactly what makes them vulnerable to the metrics game agencies play. They also cover AI, hiring, and the structural shift happening inside lean agencies: fewer people running more sophisticated operations, with intellectual curiosity replacing credentials as the primary hiring filter. This conversation is for founders, operators, and marketers managing e-commerce brands or working inside them. It is for people who want to understand how to read a marketing dashboard like a business owner, not a media buyer. If you are running paid ads, managing agency relationships, or trying to understand why your numbers look fine but growth feels stuck, this one will reframe how you see the whole game. Topics covered include e-commerce marketing strategy, return on ad spend, customer acquisition cost, new customer acquisition cost, direct-to-consumer marketing, lifetime value optimization, average order value, media efficiency ratio, cross-channel attribution, marketing analytics, agency accountability, e-commerce brand building, AI in marketing operations, digital marketing metrics, and health and wellness brand growth.
