Retail Media in Europe: Fragmentation, Trade Budgets and Proof

European retail media is usually benchmarked against Meta and Google. It should be benchmarked against an end-cap and a paper coupon. Marketers are reported to be funding retail media largely from existing shopper and trade budgets, replacing printed coupons and in-store displays with dynamic banners — which means the honest test is not whether a retail media network beats paid social, but whether it beats the promotional mechanic it displaced. In February 2026 the IAB and IAB Europe published a framework explicitly separating measurable retail media from legacy trade spend, which suggests the industry has noticed the same thing.

1. How big it actually is

Two credible sources give materially different answers, and for anyone budgeting European digital marketing the gap is instructive rather than embarrassing.

Sources: IAB Europe AdEx Benchmark 2025, published 7 July 2026, recording retail media growth of 16.7% to €13.3 billion and passing 10% of total digital ad spend for the first time; WARC forecasts as cited in 2026 market analysis. IAB Europe explicitly notes its AdEx retail media numbers are sell-side focused and therefore lower than the total retail media figures it publishes separately. These are not competing estimates of the same thing — they measure different scopes, and quoting one against the other is a common error.

The IAB Europe milestone is the more useful fact regardless of absolute size: retail media passed 10% of total European digital ad spend for the first time, growing faster than display, search or classifieds.

2. Why European retailers built these networks

This is the part that explains everything else, and it is rarely stated plainly. European retailers face compressed fulfilment economics that erode core profitability, and media revenue carries operating margins reported at 50–70%.

European grocery delivery is a difficult business. Selling advertising against the customers who use it is not. Retail media exists because the core operation stopped paying, and understanding that tells you who holds the negotiating leverage.

Reported analysis notes the incremental profit lets chains reinvest in price competitiveness, logistics and loyalty. For a brand buying that inventory, the implication is direct: you are funding a margin repair programme, which is a reasonable trade only if the media works on its own terms.

Based on reported operating margin figures for retailer media revenue and the documented pivot driven by compressed fulfilment economics. Incentive analysis is operational judgement. Note that Criteo is reported to run the retail media infrastructure of several major European retailers including Carrefour and Tesco, so networks that appear independent may share plumbing.

3. The trade budget question nobody asks

Retail media is reported to be funded largely from existing shopper and trade budgets, replacing paper coupons and end-caps with dynamic banners that adjust in real time. If that is where the money comes from, the comparison that matters changes completely.

Based on reported analysis that marketers fund retail media largely from existing shopper and trade budgets, replacing paper coupons and end-caps with dynamic banners. The benchmarking argument is mine and is offered as a planning frame rather than a finding.

The industry appears to be converging on the same point. In February 2026 the IAB and IAB Europe published a formal framework separating measurable retail media from legacy trade spend — an acknowledgement that the two have been blurred, and that separating them is a prerequisite for evaluating either.

4. Fragmentation is worse here than in the US

This is the structural difference that makes European retail media a harder operating problem than the American version, and it follows directly from Europe having no single dominant grocer.

Sources: reported figures that Amazon and Walmart absorb over 84% of US retail media budgets and that around 73% of UK retail media spend goes to Amazon; IAB Europe’s standardised definitions covering 31 European markets; reported challenge that advertisers now manage campaigns across five to seven or more networks with separate logins, reporting and naming conventions.

For European performance marketing planning, the UK figure is worth isolating. At roughly 73% Amazon share, the UK behaves more like the US concentration pattern than like continental Europe, where national grocers hold materially stronger positions. A pan-European retail media plan that treats the UK and Germany as the same problem will be wrong about both.

In continental Europe the dominant share is reported to sit with Carrefour Links, the Tesco Media and Insight Platform in partnership with dunnhumby, and Amazon Ads Europe — with Criteo supplying retail media infrastructure to several major retailers. So European ecommerce marketing teams face a landscape that is fragmented at the front end while being more consolidated than it appears underneath.

5. Closed loop is a promise, not a delivery

Retail media’s entire pitch is closed-loop measurement: the network sees the ad and the purchase. Reported analysis is blunt about the gap between that promise and what most networks actually provide, which is last-click attribution within limited windows.

Based on reported analysis of the gap between retail media’s closed-loop promise and typical last-click delivery, first-party data coverage gaps for shoppers not enrolled in loyalty programmes, and Forrester’s finding that 86% of decision-makers rate attribution improvement a high or critical priority.

The loyalty coverage gap deserves particular attention in Europe, where loyalty penetration varies widely between markets and retailers. A network that can only see loyalty-card shoppers is reporting on a subset and describing it as the whole.

The seller of the media is also the auditor of the media. That is the same structural problem identified in the US analysis, and no amount of dashboard sophistication resolves it.

6. The standardisation effort underway

Europe is further along on this than most marketers realise, and the timeline is worth knowing because it changes what you can reasonably demand from a network.

Sources: IAB Europe Retail & Commerce Media Committee publications, including definitions covering on-site retail media, off-site retail media and in-store digital retail media as three distinct categories; IAB in-store measurement standards finalised in 2025; February 2026 joint framework as reported.

The three-category split — on-site, off-site and in-store digital — is the practical takeaway. When a network quotes performance, establish which category the number describes, because they are not comparable and were routinely reported as though they were.

7. In-store is the growth edge

In-store retail media is projected to grow at around 11.62% annually against overall market growth of roughly 6.35%, as connected screens, smart carts and loyalty-linked apps turn physical aisles into measurable inventory. Tesco and Carrefour are reported to be scaling digital screen networks at the shelf edge.

Two cautions belong alongside that. Measurement in-store has historically been fragmented — every retailer’s screens, every signage vendor and every attribution methodology different — which is precisely why the IAB standards finalised in 2025 matter. And deployment is genuinely hard: the Walgreens and Cooler Screens dispute has become the public illustration of sensor reliability, measurement gaps and infrastructure limits in stores never built for always-on displays.

Based on reported in-store growth projections of 11.62% CAGR against 6.35% overall, IAB Europe’s three-category framework, and commentary on in-store deployment challenges. Growth projections come from a market research provider and should be treated as directional.

8. What to do before spending anything

Reported practitioner guidance is consistent on sequencing, and the first step is the one most often skipped.

Based on reported five-step practitioner guidance for European brands entering retail media, including auditing retail presence before media spend and suggested test budgets of several thousand euros monthly over at least 90 days. The holdout step is my addition, consistent with the incrementality emphasis appearing across 2026 industry commentary.

The first row is the highest-return advice in European performance marketing generally and is regularly ignored because it is not media work. If the product page converts poorly, retail media buys more traffic to a page that converts poorly.

9. What this page does not cover

Scope statement. The fourth row is deliberate: publishing a benchmark ROAS across networks that define attribution differently would be misleading, which is the same reason the industry is standardising definitions.

10. The 90-day plan

Indicative sequencing. The second step — identifying which budget funds the spend — determines what you should compare results against, and is usually skipped entirely.

11. Mistakes to avoid

Recurring errors in European retail media planning; illustrative.

12. What changes next

Standards are arriving quickly. With pan-European definitions published, in-store measurement standards finalised and Commerce Media Measurement Standards V2 in consultation, the vocabulary gap that made networks incomparable is closing — which will make it harder for a network to define attribution in whatever way flatters it.

Incrementality is becoming the metric that matters. Industry commentary increasingly frames the standardisation gap and the rise of incrementality as the defining issues, which aligns retail media evaluation with the holdout discipline the rest of this cluster recommends.

Commerce media extends beyond the retailer. The category is broadening to carry retailer first-party data off retailer-owned properties into connected TV, social and other commerce-adjacent environments — which increases reach and simultaneously weakens the closed-loop claim that justified the channel.

Key Takeaways

• Retail media passed 10% of European digital ad spend for the first time, growing 16.7% to €13.3 billion on IAB Europe’s basis.
• €13.3bn and €22.3bn are different scopes, not competing estimates. IAB Europe says so itself.
• European retailers built these networks because fulfilment stopped paying. Media revenue carries 50–70% operating margins.
• If trade budget funded it, benchmark against the end-cap it replaced, not against paid social.
• Fragmentation is worse than in the US — five to seven or more networks, 31 markets, and no single grocery leader outside the UK.
• Closed loop is usually last-click in a short window, with coverage gaps for non-loyalty shoppers.
• Fix product pages before buying media. Retail media amplifies whatever the page already does.

Frequently Asked Questions

Conclusion

Retail media is the fastest-growing significant channel in European digital marketing and the one most likely to be evaluated against the wrong benchmark. It grew 16.7% to pass a tenth of all European digital ad spend, it is genuinely closer to the purchase than any other format, and it is sold by parties who need the margin and audit their own results.

None of that makes it a bad buy. It makes it a buy that requires the questions nobody asks at the pitch: which budget is funding this, which measurement category is being reported, what share of shoppers the loyalty data actually covers, and what happened in the markets where you did not run it. Answer those and European ecommerce marketing gains a genuinely useful channel. Skip them and you have replaced a measurable end-cap with an unmeasurable banner and called it transformation.
