Retail media: why brands are rushing in for 2026

In short: retail media is advertising delivered on retailers’ channels (sites, apps, in-store screens), closest to the act of purchase. It’s one of advertising’s fastest-growing segments, combining strong purchase intent with transactional data.

What it is

When a retailer sells ad placements on its own inventory — sponsored products in search results, banners on the product page, in-aisle screens — that’s retail media. The brand pays to be visible where the shopper is already buying.

Why it’s exploding

• Maximum purchase intent: you reach the customer at the moment of decision.
• First-party data: the retailer knows real purchases, valuable in a cookieless era.
• Measurement down to the sale: exposure can be linked to purchase.
• A new revenue stream for retailers, highly profitable.

Common formats

• Sponsored products in internal search.
• On-site banners (home, categories, product page).
• Off-site retail media: delivery beyond the retailer’s site, using its data.
• In-store: screens and setups in shops.

Challenges

Standardising measurement, comparability across networks, and budget arbitrage with other levers. Retail media doesn’t replace the brand: it excels at the bottom of the funnel, to combine with awareness.

FAQ

Is retail media only for large retail? No: any player with an audience and purchase data (e-commerce, marketplaces, specialty chains) can build a retail media network.

Difference from classic search advertising? The intent-auction principle is similar, but retail media relies on the retailer’s real purchase data and is often measured down to conversion.

Is it suitable for small brands? Yes, notably via sponsored products, which are accessible and budget-controllable.
