Retail media: advertising where the buyer is already deciding

Retail media is advertising spend within selling platforms such as Amazon, El Corte Inglés, Carrefour, or Mercadona. It is the fastest-growing channel in the Spanish digital ecosystem and the closest to the point of conversion.

When a shopper searches for "protein powder" on Amazon or "detergent" on Mercadona Online, they have already made the category decision. What they still need to decide is which brand. Advertising that appears at that moment carries a purchase-intent context that classic Paid Media rarely achieves.

Retail media has grown because it works, but also because it is complex. Every platform has its own bidding system, its own ad formats, and its own metrics. A retail media strategy that is not coordinated with catalog management, pricing, and stock availability produces inefficient spend.

At Elogia we operate retail media as part of the marketplace strategy, not as a standalone channel. Advertising investment decisions within Amazon or a digital retailer are made using the same data as pricing, catalog management, and profitability decisions.

What we do

Retail media strategy by platform

Each platform has its own particularities. Amazon Ads has its own bidding logic and attribution model. Retail media on El Corte Inglés, Carrefour, or Mercadona works differently. We design the strategy for each platform based on the brand's objectives: new product visibility, position defense, new buyer acquisition, or conquest of a competitor's shoppers.

Sponsored Products, Sponsored Brands, and DSP campaign management

We manage the most relevant retail media formats on each platform, from sponsored product ads to programmatic display campaigns within Amazon DSP. Campaign optimization is connected to the catalog's conversion and profitability data.

Coordination with catalog management

A Sponsored Products campaign that drives traffic to a poorly optimized product listing or an out-of-stock item converts poorly. Retail media management is coordinated with the catalog team to ensure that the ad spend is backed by the necessary content and availability.

Incrementality measurement

Retail media has an attribution problem: some of the sales attributed to campaigns would have happened anyway. We measure the true incrementality of campaigns to determine what share of the result is attributable to the ad spend and what share would have occurred without it.

Frequently asked questions

Classic Paid Media (such as Google Ads or Meta Ads) intercepts the buyer before they reach the point of purchase. Retail media appears inside the platform where the buyer is already searching or shopping. The intent context is higher in retail media, which typically translates into higher conversion rates, although the cost per impression is also greater.

Brands with distribution in the retailers that offer retail media: Amazon, El Corte Inglés, Carrefour, Mercadona. Also brands competing in categories with a strong marketplace presence that want to defend their position against private labels or direct competitors. Retail media makes less sense for very low-turnover products or those with exclusive distribution in their own channel.

The main metrics are campaign ROAS, share of impressions in the category, attributed cost per sale, and incrementality. The last one is the most important and the hardest to measure: how many sales are incremental compared to what would have occurred without the campaign.
