Rita Zahir, VP of Marketing and E-Commerce at Unique Vintage, delivers a data-dense masterclass on the one metric most e-commerce brands are still getting wrong: the difference between revenue and profit. With 20 years across Shoes.com, Famous Footwear, Polaris, and now a female-owned vintage-inspired brand, Rita breaks down why "let the algorithm handle it" is the most dangerous phrase in modern performance marketing — and how a combination of custom behavioral segmentation and contribution-margin-level analytics helped her team beat Meta Advantage+ ROAS by 30% during the most volatile periods of the calendar. This is a rare, practitioner-level conversation about the infrastructure behind profitable e-commerce growth.
