What Is Retail Media? A Plain Explanation With Real Numbers

What retail media actually is

Retail media is advertising sold by a retailer, on the retailer's own digital or physical real estate, targeted using that retailer's first-party shopper data. On Amazon that means Sponsored Products in search results, Sponsored Brands placements, Sponsored Display, and Amazon DSP — Demand-Side Platform, the programmatic buying tool for display, video and audio, both on Amazon and off it. (DSP here means Demand-Side Platform, not Delivery Service Partner, the courier franchise — the two get confused constantly.)

The thing that makes it different from a normal display ad network: the retailer knows what the shopper actually bought, not just what they clicked. A publisher can tell you someone read an article about air fryers. A retailer can tell you someone bought an air fryer, what brand, what price point, and whether they came back for filters six months later. That purchase data is the entire value proposition.

What a retail media network is

A retail media network is the infrastructure behind that advertising — the ad server, the auction, the reporting, and the data layer that lets a retailer sell inventory to third-party brands across its owned properties and, often, a wider off-site network of publishers it has struck deals with. Amazon Ads, Walmart Connect, Instacart Ads and Target Roundel are all retail media networks. Criteo isn't a retailer itself, but connects retailer data to advertising inventory across the open web — a different piece of the same supply chain, and a genuinely useful one for retailers who don't want to build their own ad server.

Retail media networks generally have two layers: onsite (ads inside the retailer's own app or website, close to a buy button) and offsite (the retailer's audience data used to target ads on other publishers' pages, in a browser, or in a streaming app). Amazon DSP does both. Sponsored Products only does the first.

How retail media works, with real numbers

Take a normal full-funnel setup on Amazon: DSP display and video build awareness with shoppers who haven't bought the category before, Sponsored Brands and Sponsored Products catch people actively searching, and Sponsored Display retargets people who viewed but didn't buy. Each layer is priced and measured differently — CPM for display and video, cost-per-click for search-based formats.

Across 30 advertisers we managed in July 2026, that combination returned 6.04x return on ad spend on 78.4 million impressions at a $4.00 CPM, with a blended $1.42 cost-per-click and a blended cost per acquisition of $5.49 across 57,137 attributed purchases — 20.1% of them from shoppers new to the brand. Numbers like that only mean something if you know what they're not measuring: last-click attribution will credit a DSP impression and a Sponsored Products click for the same sale, twice, if the shopper saw both before buying.

The honest fix is a holdout: hold back media from a matched group of shoppers, run the campaign against everyone else, and compare what actually happened, not what the last click said happened. Amazon Marketing Cloud is where that reconciliation happens — it's the only place DSP and sponsored ads stop double-counting each other.

Retail media strategies, and the mistake most people make

Most retail media strategy is funnel allocation: how much goes to awareness (DSP), how much to intent-capture (search ads), and how much to retention (retargeting, subscribe pushes). Brands that put everything into Sponsored Products because it shows the cleanest last-click ROAS are often optimizing for the metric, not the outcome — they're capturing demand they might have gotten anyway.

The mistake we've made ourselves: reading a DSP campaign's last-click ROAS as gospel, when a holdout later showed the real lift was smaller because a chunk of those conversions would have happened from organic search or a Sponsored Products click regardless. That's not a reason to avoid DSP — it's a reason to measure it properly before scaling it.

If a number looks wrong — ROAS too high, CPA too low — check whether it's last-click before you check whether the campaign is broken. If a holdout test comes back flat, don't kill the channel outright; check reach and frequency, check whether sponsored ads already covered the same shoppers, and check the creative before assuming display doesn't work for the category. Every change should carry three things before it runs: the evidence behind it, a measurement plan, and a rollback trigger — otherwise you're guessing twice.

Retail media examples

On Amazon: Sponsored Products (cost-per-click ads in search and on product pages), Sponsored Brands (headline placements with logo and multiple products), Sponsored Display (retargeting on and off Amazon), and Amazon DSP (programmatic display, video and audio, on Amazon-owned sites and off, including streaming and connected TV). Off Amazon: Walmart Connect, Target Roundel, Instacart Ads and Kroger Precision Marketing run similar onsite formats on their own first-party data. Criteo doesn't own retail inventory itself but connects that data to ad space across the open web for retailers who'd rather not build an ad server from scratch.

The brands running this kind of full-funnel mix span categories: cookware (HexClad), leather goods and travel accessories (Ridge), beauty (BK Beauty), grooming (Beardbrand), gardening (Epic Gardening), craft kits (The Woobles). None run identical strategies — a repeat-purchase grooming brand weights toward retention differently than a gift-driven craft brand weights toward awareness — but all are buying some combination of search ads, display and video against the same retailer's shopper data.

Where Dr. DSP fits

Dr. DSP is Fable 5's managed product for Amazon DSP specifically, built by Full Circle, which has managed more than $500M in revenue across 100+ brands. It exists because the DSP layer of retail media is the hardest to measure honestly and the easiest to oversell — the incrementality argument above is the whole reason for it. There's no published price: it's a demo, the first 30 days free, and pricing set on the call against your actual budget and scope, with the Orbit software included either way. Whether or not you ever buy from us, that's the trade-off worth pricing against any DSP vendor.
