Retail media is checking out fast, but with so many networks, formats and promises flying around, it’s easy to get lost in the aisles. This essential guide cuts through with clear questions, expert insights and more.
Retail Media for Drummies: the guide that makes sense of the $100bn boom
It started in the search bar. Now, it’s reshaping the media map. Retail media has gone from sponsored listings to full-funnel force, spanning in-aisle screens, shoppable video and AI-powered targeting. It’s fast becoming one of marketing’s most powerful levers, offering real-time relevance, first-party data and closed-loop performance that promises to connect ad spend to actual sales.
But with new networks launching weekly, formats stacking up and metrics still in flux, the landscape is getting crowded and complex. For marketers navigating their way around the aisles, our Retail Media for Drummies guide breaks down what matters, what works and what to ask before you buy in.

The short version: everyone wants in. Retailers are becoming media owners. Media owners are acting more like retailers. And CMOs are under pressure to prove performance and unlock new growth, with or without more budget.
But beneath the surface, the picture’s more nuanced:
It’s no longer just about sponsored search. Retail media now spans the full funnel – from brand-building video on CTV and social, to programmatic offsite display, to hyperlocal in-store activations.
The measurement mess is real. Everyone’s talking about closed-loop, but not everyone defines it the same way. Incrementality is still the gold standard, but how many networks are actually offering it? As CVS Media Exchange’s Parbinder Dhariwal says: “Retail media won’t keep growing unless we can prove it works. Attribution, incrementality, consistency – without those, the channel risks stalling just as it hits its stride.”
AI is driving innovation (and tension). From agentic media orchestration to dynamic product matching and autonomous checkouts, AI isn’t just powering media… It’s starting to redesign the shopping journey. As Molly Anderson, VP of retail media at VaynerMedia, says: “AI being applied to product discovery, basket building and even platforms for shopping is going to be our industry’s next biggest change.”
Not all networks are equal. With over 100+ retail media networks (RMNs) now live globally, marketers need to look beyond reach and CPMs. Is there real first-party data? Real in-store presence? Real outcomes?
We’ve whittled down the shopping list into five essential buyer questions:
1. Can I prove real ROI, not just ROAS?
Measurement varies wildly between platforms. Push for incrementality, independent verification, and clean room access.
2. Which platforms make the most sense for my brand?
There’s more to the game than Amazon and Walmart. Niche or category-specific RMNs (think Ulta, Boots, Ocado) can offer more targeted reach, better context and deeper loyalty data. The smart approach? A focused, test-and-learn strategy, not a media land grab. Prioritize networks with clear reporting, strong data governance and the ability to link spend to sales outcomes.
3. How do I balance brand and performance?
Retail media used to live at the bottom of the funnel. Not any more. Today’s most effective strategies layer brand-building video and immersive formats with performance-led placements like sponsored products and search. Retailer data allows for smart segmentation, sequential storytelling and tighter creative alignment, making the brand versus performance debate a false choice.
4. Is this just retail media or commerce media?
Retail media is expanding beyond retail. Non-retail players are building networks too. From travel to telco, if it has first-party data and transaction signals, it’s on the table. This opens new possibilities for marketers but also raises fresh questions around governance, audience overlap and integration into the wider media mix.
5. What makes this different from every other ad channel?
Unlike social or programmatic, retail media operates at the moment of transaction. It connects ad exposure directly to purchase behavior and, increasingly, across both physical and digital environments. That makes it more than a media buy. It’s a business lever. The real magic lies in the moment – that near-instant conversion window when intent meets availability.

Before you hit ’add to basket’, remember this:
What does success actually look like? Is it ROAS, new-to-brand growth, incrementality, brand lift, or all of the above? Get alignment up front.
Are your teams working from the same playbook? Shopper, brand and media leads should be planning together – not optimizing in silos.
Can you measure what matters? Push beyond platform-reported metrics. Ask about clean rooms, holdout testing and whether their definition of “closed loop” matches yours.
Are you being shown a shiny front-end or a smart back-end? A slick UI means nothing without the infrastructure to support omnichannel delivery and real-world outcomes.
Is your creative working as hard as your media? In a world of retail media carousels, PDPs and dynamic video, repurposed banners won’t cut it.
And finally: are you buying on your terms or letting the platform steer the trolley? With AI starting to drive spend decisions, make sure your strategy leads and automation follows.
