Retail Media Networks: How eCommerce Brands Earn Revenue Post-Purchase

Retail media has become one of the fastest-growing segments of digital advertising. In Europe, the market is projected to pass €30 billion by 2028 as retailers such as Tesco, Carrefour, and Zalando expand their media networks. In the US, ad spend is expected to reach over $71 billion in 2026, led by networks such as Amazon Ads, Walmart Connect, and Target Roundel.

More broadly, this growth sits within the rise of commerce media, a wider category that includes advertising across the entire Commerce Journey , from retailer websites and marketplaces to brand-owned eCommerce experiences and other media environments powered by commerce data.

Overall, retail media is benefiting from retailers' first-party purchase data, closed-loop measurement, and the continued growth of eCommerce, positioning it as a key channel alongside search and social advertising.

For eCommerce brands, retail media represents both an advertising channel (a way to reach customers on other retailers' platforms) and a revenue opportunity (a way to monetise your own traffic by hosting relevant commercial placements). It's the latter that this article focuses on, exploring how post-purchase retail media can unlock incremental revenue from transactions already occurring.

What is a retail media network?

A retail media network is a platform that enables partner brands to advertise within a retailer's digital environment, such as its website, app, search results, and order confirmation pages. The retailer earns revenue from the placements, and the advertiser reaches customers at or near the point of purchase. 

This makes retail media different from traditional digital advertising, which targets audiences based on inferred demographics or behavioural data. Retail media reaches customers in a confirmed buying state. Placements typically appear on retailer websites, mobile apps, search results, product listing pages, and increasingly across off-site channels powered by retailer first-party data.

Large retail media networks, such as those operated by major marketplaces and grocery retailers, have established this model at scale. What's changed recently is the accessibility of retail media infrastructure for mid-market and enterprise eCommerce brands that don't operate at that scale but still have valuable, high-intent audiences.

For these brands, building a retail media capability means activating their own checkout traffic as a commercial asset, allowing relevant partner brands to reach their customers in a way that benefits all parties: 

• The advertiser gets access to a high-quality, transactional audience
• The retailer generates revenue from traffic they were already driving
• The customer receives a relevant, brand-safe offer at a moment when they're genuinely open to it

This creates a model where the Commerce Journey works harder at every stage, turning existing traffic into a stronger commercial opportunity without adding friction to the purchase experience. It allows brands to extract more value from the journey while keeping the experience relevant for the customer.

Which retail media placement delivers the most value?

Within the retail media space, the post-purchase window is consistently one of the highest-performing placements across the Commerce Journey. The reason is straightforward: at this moment, the customer has completed a transaction. All the friction and uncertainty of the purchase decision is behind them. They're in a state of positive completion, their attention is on the brand, and they're genuinely open to what comes next.

This is categorically different from other advertising moments. A display ad reaches someone who may or may not be in a buying state. A sponsored listing reaches someone who is searching but has not yet decided. A post-purchase placement reaches someone who has just spent money and is therefore demonstrably in a transactional mindset.

It also differs from a post-purchase upsell. An upsell asks the customer to spend more with the same retailer, which can feel like a second sales pitch. A post-purchase partner offer gives the customer something extra from a complementary brand, so it reads as a reward for the purchase rather than an attempt to extend it.

The conversion rates on well-executed post-purchase placements consistently reflect this advantage. Brands activating post-purchase retail media typically see engagement rates that significantly outperform placements at other stages of the journey because the audience is uniquely qualified and uniquely receptive.

How to build a post-purchase retail media strategy?

A post-purchase retail media strategy rests on four connected decisions: who appears in your placements, how those placements look, how you measure them, and how you improve them over time.

Partner and advertiser curation

The brands that appear in your post-purchase experience reflect directly on your own brand. Brand safety requires rigorous curation, including approving partners before they go live, monitoring the quality of their offers, and removing any placements that do not meet the standard.

Curation also drives performance. Relevant, well-matched partner offers consistently outperform generic ones. A post-purchase offer that complements what the customer has just bought, whether by category, lifestyle affinity, or occasion, converts at a higher rate. It also creates a better customer experience than a random offer.

The distinction between endemic and non-endemic advertisers is relevant here. Endemic brands, meaning those whose category naturally complements your own, are the easiest starting point for post-purchase retail media because the relevance is already there. Non-endemic brands can also perform well, provided the offer is genuinely valuable and the placement is thoughtfully designed. 

Placement design and native integration

Post-purchase retail media performs best when it feels like a natural extension of the shopping experience rather than an interruption. Placements that match the visual language of the confirmation page, use language that echoes the brand's tone, and feel like a reward rather than a promotion consistently outperform those that look like banner ads. This is what we call white-label retail media.

Investment in placement design is one of the best optimisation opportunities in retail media. 

Measurement architecture

Retail media needs clear measurement to prove it is worth the investment. For the retailer, the main question is whether it is generating meaningful extra revenue. For the advertiser, the question is whether it is delivering a better return than other channels.

The most important metrics to track include revenue per thousand completed transactions, conversion rate, click-through rate, and any impact on the retailer's own repeat purchase rate. This last point matters because a strong post-purchase experience can improve customer loyalty, even when the offer itself comes from a partner brand.

The commercial model matters too. Under a minimum revenue guarantee, the host receives a fixed payment regardless of how the placements perform, which gives predictable income but usually a lower ceiling. Under a CPA revenue share, the host earns a percentage of each conversion the placement drives, so income scales with performance. Knowing which model suits your traffic volume and risk appetite shapes the rest of the strategy.

Ongoing optimisation

The best retail media strategies evolve through continuous optimisation. They test different partner categories, placement positions, offer formats, and audience segments to find the combination that maximises both revenue and customer experience.

Platforms with built-in A/B testing capabilities make this process straightforward. Over time, systematic testing leads to significant performance improvements, while the learnings from each test strengthen future partner selections and placement decisions.

What is commerce media?

Retail media sits within the broader category of commerce media, the umbrella term for advertising and commercial activity that takes place within the buying journey itself. As third-party cookies have declined and first-party data has become more valuable, commerce media has grown significantly because it reaches customers based on real purchase intent and real shopping behaviour.

For eCommerce brands, this shift creates a major opportunity. The first-party data generated by customer transactions holds increasing value for advertisers seeking qualified audiences.

This includes:

• what people buy
• how often they buy
• which products they buy together
• the price points they respond to

Retail media networks turn that data value into revenue. Post-purchase stands out as one of the strongest points in that journey because the customer has just completed a purchase, showing both intent and spending power in a way that predictive modelling cannot match.

What results can you expect from post-purchase retail media?

Results from post-purchase retail media vary by category, traffic volume, and implementation quality. Typical ranges for well-implemented programmes include conversion rates of 3-15% on post-purchase offers, meaningful incremental revenue per thousand transactions, and positive secondary effects on repeat purchase rate. Receiving a relevant, brand-safe offer after a purchase creates a positive brand association that extends beyond the immediate transaction.

The most important variables are the quality of the partner and the curation of offers. High-relevance, high-quality offers from well-matched brands consistently outperform generic placements by a significant margin, which is why investment in the curation process delivers disproportionate value.
