Most e-commerce founders obsess over top-of-funnel conversion metrics or acquiring cheap email leads, but they are ignoring the single most important number: Customer Lifetime Profit (CLP). In this episode of Marketing Misfits, hosts Norm Farrar and Kevin King sit down with Matthew Barnes, an earthquake engineer turned e-commerce conversion scientist.

Matthew explains why traditional A/B testing and basic conversion rate optimization (CRO) are completely backwards. He breaks down how he built The Tool (Proteus Digital Lab) a highly advanced testing and intelligence platform that connects Shopify data, Meta ad touchpoints, and Klaviyo data to prove which customers actually generate profit and which ones you are acquiring at a loss. If you run an e-commerce brand and want to understand how to optimize your store like an engineer, do not miss this technical, deep-dive episode!
