Let’s be real: retail media is full of shiny, headline-grabbing metrics that come and go with the latest trends. But in today, I’m digging into the metrics that brand leaders swear by day in and day out AKA the workhorses that drive real business decisions. I asked three brand-side leaders to share that one metric they come back to time and again, even when the industry is distracted by the 'next big thing'.

We’ll hear why TACoS is the daily go-to for navigating the quirks of Amazon vendor revenue, how market share keeps your brand grounded in a sea of competitive noise, and why new-to-brand is the holy grail for understanding true discovery. If you're ready to cut through the fluff and focus on what actually moves the needle, this one’s for you.
