retail media (RMN)

advancedwidespread

Retail media is advertising that a retailer sells to brands on its own online store, app or in its physical stores, built on its customer purchase data.

In plain terms

Good shelf space used to cost money in stores: manufacturers paid for eye-level shelves or racks near the checkout. Retail media is the same in the internet age. The retailer rents out their website's search results, the app's home screen, and the store's displays as advertising space.

The difference lies in the data. If you are logged in or use a loyalty card, the merchant knows what you bought last week, what you put in your cart, and what you searched for. This lets the merchant show the ad to someone who is about to buy, and afterward also see whether you bought the product after the ad.

This is valuable for brands because they reach consumers at the moment of purchase, not hours earlier on a news portal. For the merchant, it is new revenue with a profit margin typically much higher than that of the goods.

How it works

The merchant collects their own customer data: searches, cart contents, past purchases, and loyalty card usage.
It creates advertising spaces: sponsored products at the top of search results, banners on the page, screens in stores, and even displays ads on other websites based on its own data.
Brands bid for these spots on an advertising platform, mostly paying per click or per impression.
The system, increasingly with artificial intelligence, decides which advertisement to show to which customer and inserts it among search results.
The retailer ultimately reports how many ads were followed by an actual purchase. The brand can thus see how many sales can be linked to the ad, but not whether the customer would have bought the product without the ad.

An everyday example

You search an online store for "laundry gel", and next to the first two results, in small print, it says: "Sponsored". These did not appear first because they are the best or cheapest, but because the manufacturer paid for the spot.

Who is affected

everyoneAs a buyer, you encounter paid results daily, and it is worth knowing that the order does not always reflect quality.

marketerAn increasingly large share of advertising spend goes here because the ad can be directly linked to the actual purchase. → Marketing

A common misconception

MythAt the top of an online store's search results list, the best or most popular products always appear.

In realityTop positions are often paid advertising spots. These must be labeled, but the "Sponsored" tag is frequently barely noticeable.

Limits and risks

The seller sells the ad and measures its results at the same time, so an independent party rarely checks the return figures.
Most retailers run their own closed systems with different metrics, making campaigns difficult to compare. Common measurement standards are only just spreading.
Based on your purchase data, you receive targeted ads, which raises data privacy concerns, especially for sensitive products such as medicines.
Smaller manufacturers may fall behind because large brands can outbid them for visible spots.

Similar, but not the same

search ad – Search ads appear in general search engines, while retail media appears directly at the point of purchase on the merchant's own platform.
trade marketing – Trade marketing concerns traditional in-store presence, shelf space, and promotions, while retail media is its data-driven, digitally measured advertising variant.
affiliate marketing – In affiliate marketing, an external partner directs the shopper to the store for a commission; in retail media, the store itself sells ad space on its own channels.

A brief history

Manufacturers have paid for better shelf space and in-store advertising for decades. Amazon's advertising business turned the digital version into a major industry in the 2010s, after which major retail chains launched their own advertising networks.

Where things stand

At the end of 2026, retail media is one of the fastest-growing segments of the digital advertising market. Most major international retailers and many regional chains run their own networks. The industry's new question is how to advertise when an AI agent, rather than the shopper, searches for and chooses products.
