In conclusion

Retail media is no longer an emerging channel. It is more integrated into the shopping cycle than ever and will continue to evolve as the potential of retail media is more full realised.

Our findings show that shoppers experience retail media as part of the overall retail journey - and increasingly expect it to be personalised and consistently relevant, from purchase through to the retail media they see next. They value experiences that feel useful, connected and genuinely additive.

To meet these expectations, retailers and brands must move beyond fragmented execution and align around shared shopper insight. The most effective retail media is collaborative and trusted, working as part of a connected ecosystem that brings together loyalty, personalisation and category strategy to deliver better outcomes for shoppers, retailers and brands alike.

For retailers and brands, the implication is distinct: the next step on the retail media journey is one of refinement. It's about aligning efforts to achieve a level of engagement, relevance and timing that creates a seamless decision-making process while being mindful not to introduce new methods too quickly where shoppers may question the benefits. Achieving a level of relevance that makes media feel like a seamless part of the decision-making process.

For shoppers today, retail media is no longer just about who they trust – it’s about which brands can keep and build on this trust to secure loyalty into the future.

Country-specific recommendations

US

Online retail media enjoys widespread reach in the US, but our data shows in-store displays are the most influential format (35%), ahead of online ads (22%) and personalised recommendations (18%). With ad spend still heavily concentrated online, there’s a clear opportunity here to strengthen in-store media propositions. Retailers and brands that better integrate digital and physical retail media – particularly around price and familiarity – stand to win shoppers over at the moment of decision.

UK

UK shoppers are less likely to be influenced by digital retail media (13% online ads, 12% personalised recommendations) and are more likely to say that nothing influences them (24%) when making a purchase. The opportunity here is twofold: improve execution in digital media formats, and prove their value to shoppers. Precision, clearer proof of value, and tighter alignment to budget-conscious behaviours will all be critical in strengthening the impact of online initiatives.

Methodology

This research is based on an online survey of 3,000 grocery shoppers, comprised of 2,000 respondents in the United States and 1,000 respondents in the United Kingdom.

All respondents were adults aged 18 and above, and responses were self-reported.

A mix of rating scales, multiple choice, and ranked priority questions were used to provide us with an understanding of both sentiment and behavioural intent.

The data was collected by Toluna on behalf of dunnhumby in January 2026.
