Amazon Ads Retail Media: What It Is and How Brands Use It

What retail media means, in plain English

Retail media is advertising that a retailer sells to the brands on its shelves, using the retailer's own shopper data. Instead of guessing who might want your product from browsing habits, you reach people based on what they searched for, viewed and bought in the store itself. That is why the category has grown so quickly: the ad sits next to the buying decision, and the sale is recorded by the same company that served the ad.

Amazon Ads is the largest example. When people say 'Amazon retail media' they usually mean the whole Amazon Ads toolkit, which splits into two very different systems. Understanding which one you are buying is the first decision, because they are priced, planned and measured differently.

The two halves of Amazon Ads retail media

Sponsored ads (Sponsored Products, Sponsored Brands and Sponsored Display) are self-serve. You set a bid and a budget, Amazon runs an auction, and you pay when a shopper clicks. They capture people who are already searching or browsing for something like your product. Most sellers should start here.

Amazon DSP is Amazon's demand-side platform. It buys display, video and streaming TV placements on Amazon-owned properties and on third-party sites and apps, usually billed per thousand impressions (CPM). It reaches people who have not searched yet, and it can retarget people who looked at your product and left. Because you pay for impressions rather than clicks, it needs a different way of judging success. reMKTR (remktr.com) runs Amazon DSP as a managed service for brands that want this half handled by a specialist team.

A third development worth knowing: Amazon has also announced a retail ad service that lets other retailers use Amazon's ad technology on their own sites. That is a story about retailers building their own media networks. If you are a brand buying ads, it mostly means retail media is spreading beyond Amazon.com, while your Amazon campaigns work the same way they did before.

A real portfolio, with the window and the count

Definitions only go so far, so here is what a real DSP book looks like. Across 30 advertisers that reMKTR manages, in July 2026, the portfolio produced a 6.04x return on ad spend, measured across the whole book rather than picked from the best line item. It ran 78.4 million impressions at a $4.00 CPM and a blended $1.42 cost per click once every placement type was counted.

The same book recorded 57,137 attributed purchases at a blended cost per acquisition of $5.49, and 20.1% of those purchases came from shoppers new to the brand.

Treat that as a sanity check, not a promise. It is one mixed portfolio over one month, and your account will differ with your category, price point and creative. One useful habit it teaches: when you see a very low cost per click quoted for this category, ask which placement it came from. The $0.41 CPC people quote is an online-video-only figure, and it is not the blended number across a whole book.

How to measure retail media honestly

Retail media reports look precise, which makes them easy to over-trust. Four checks keep you straight:

• Know the attribution window and method. Last-click gives the credit to whichever ad ran last, which is usually a bottom-funnel search ad. It cannot say what an impression earlier in the path contributed.
• Separate new-to-brand from repeat buyers. A campaign with a lower return but a high new-to-brand share can be doing a different job from one that mostly re-sells to existing customers.
• Look at total sales, not only ad-attributed sales. Compare ad spend to total revenue (TACoS) alongside ACoS, so you can see whether ads are adding sales or only claiming sales that would have happened anyway.
• Ask who designs the test. For incrementality, ask who sets up the holdout and who computes the result, and whether that is written into your agreement. The question applies to any vendor, including us.

Where DSP and sponsored ads run together, reconciling them in Amazon Marketing Cloud keeps the same purchase from being counted under both.

Where to start: a simple checklist

• Fix the listing first. Images, price, reviews and stock decide whether a click becomes a sale. No bid change repairs a weak listing.
• Start with Sponsored Products. It is self-serve and shows you which searches convert. Review the search term report weekly in the first month.
• Add Sponsored Brands once you have a registered brand and a few products worth featuring together.
• Look at DSP when search is no longer the limit. If you already capture the shoppers who search for you and want reach beyond them, DSP is the next step.
• Set a target before launch. Decide what return, new-to-brand share or cost per acquisition would count as success, and for which campaign type, because upper-funnel and search campaigns should not share one target.

Who should do what

If you are early, or your catalog is small, sponsored ads on your own account are usually enough and cost nothing to set up. If you want software to manage sponsored ads, Dr. PPC (drppc.ai) charges $300 a month plus 2% of ad spend, with the first 30 days at $1, Orbit included and no contract. If you want a full-service team across your Amazon business, Full Circle (fullcircleagency.com) has managed $500M+ in Amazon revenue across 100+ brands. If the question has become Amazon DSP, reach beyond search and incrementality, that is what reMKTR does: Amazon DSP, run as a service.
