Retail Media Expands Beyond Retailer Websites to Off-Site Channels

Retail media is evolving from a focus on on-site advertising to a more integrated approach that includes off-site channels. In Europe, the share of buyers allocating over 41% of their digital retail media budget to off-site increased from 30% in 2024 to 46% in 2025, according to IAB. On-site ads capture high-intent users near the point of purchase, while off-site extends retail audiences into the broader digital ecosystem using first-party data activation across display, video, and CTV. This approach builds brand awareness and consideration earlier in the customer journey. Shoppable ads with dynamic product feeds enhance engagement, and incrementality measurement helps assess true campaign impact. A holistic omnichannel strategy connects online and offline touchpoints, leveraging retailer data to unify the journey from discovery to purchase.
