Are you wondering how retail media can increase your e-commerce margins? The answer is simple: by monetizing the audience you have already attracted, you create a new source of revenue with margins far superior to those of your products. Imagine selling advertising space to your suppliers in your newsletters or on your search pages: costs are minimal, and the return is immediate.
However, this opportunity requires a deep understanding of your audience and your supplier relationships. Retail media is not just an option; it is a strategy that can transform your profitability if executed well. So, how can retail media increase your e-commerce margins? On the agenda:
Why is retail media more profitable than selling products?
How to monetize your existing audience with no extra costs?
What is the value of your audience for advertisers?
How to turn your suppliers into advertising partners?
What strategy should you adopt to launch your retail media network?
Let's get started.
Summary
Why is retail media more profitable than selling products?
Retail media stands out for its ability to generate margins significantly higher than those from selling products. Let's take a concrete example: selling a product for €100 leaves about €25 after production, shipping, and payment processing costs, representing a 25% contribution margin. In contrast, a sponsored ad in your newsletter can generate €1,000 with additional costs of only €250, leaving €750 before overheads, which is a 75% margin.
This difference is due to the fact that the costs of attracting the audience are already absorbed by your core business. You do not pay to attract readers or visitors; you already have them. Retail media leverages this existing audience to create an additional source of revenue, with no risk of product returns or inventory management.
In 2022, studies by McKinsey and Boston Consulting Group estimated the operating margins of major retail media networks at over 70%. Proof that this model is not only viable, but extremely lucrative for those who know how to leverage it.

How to monetize your existing audience without additional costs?
Retail media works just like advertising in publishing: a publisher attracts readers with content, then sells access to this audience to advertisers. For an e-commerce merchant, the audience consists of your customers and subscribers, attracted by your products and services. You can monetize this audience with no additional costs by using your existing channels.
Take the example of a specialty retailer who sends four monthly newsletters to 40,000 subscribers. A supplier agrees to pay €1,500 per month for a recurring sponsorship, hoping to generate 400 additional sales. The production and sales costs of this sponsorship amount to €300 per month, leaving a contribution of €1,200, which represents an 80% margin. The merchant simply uses their existing audience, with no additional investment.
This logic also applies to your search result pages, your category pages, your buying guides, and other sections of your site. Every space where your customers interact can become a profitable advertising medium.
What is the value of your audience to advertisers?
An e-commerce merchant's audience is often more valuable to advertisers than that of a general publisher, because your visitors are close to making a purchase. A publisher might know that a visitor is reading articles about hiking. An outdoor retailer, on the other hand, knows that this same person has searched for waterproof hiking boots, viewed several pairs, and bought hiking socks six months ago.
This deep understanding of purchasing behavior is a major asset. Advertisers pay to access consumers with a clear commercial intent, which increases the value of your advertising inventory. You are not simply selling impressions; you are selling access to already engaged potential buyers.
To maximize this value, it is essential to structure your customer data and use it to demonstrate to advertisers the relevance of your audience. The more you can prove your visitors' purchase intent, the more you can justify high advertising rates.
How to turn your suppliers into advertising partners?
Supplier-funded advertising is not new to retail. Co-op programs have long subsidized ads promoting their products. Retail media extends this relationship: instead of sharing the costs of external ads, suppliers pay the retailer directly to access their audience.
For an e-commerce merchant, this is a new source of revenue from companies they already know and work with. A 2025 TransUnion study found that 70% of retail media spending was incremental to suppliers' broader trade budgets. This means retail media generates new revenue rather than shifting existing budgets.
To turn your suppliers into advertising partners, start by identifying those with a strategic interest in promoting their products to your audience. Offer them advertising formats integrated into your customer experience, such as placements in your newsletters or highlights on your product pages.
What strategy should you adopt to launch your retail media network?
Launching a retail media network requires a clear and progressive strategy. Start by auditing your existing communication channels: newsletters, search pages, category pages, buying guides. Identify the spaces where an advertisement would be relevant without harming the customer experience.
Next, define your advertising formats and rates. You can offer newsletter sponsorships, banners on your category pages, or placements in your buying guides. Test different formats and measure their performance to adjust your offer.
Finally, approach your suppliers with a clear proposal: show them the value of your audience, the expected results, and the associated costs. Start with a small group of suppliers to validate your model, then progressively expand your network. This gradual approach allows you to minimize risks while maximizing opportunities.
How does retail media double your revenue?
One final important point: when the ad buyer is a supplier, the e-commerce store wins twice. First, it earns direct advertising revenue. Second, it benefits from higher product sales because the advertising stimulates demand. This dual revenue stream is a unique advantage of retail media.
This mechanism is reminiscent of cooperative campaigns, where the supplier invests in advertising to sell through the distribution channel, even though the retailer benefits from this double opportunity. The supplier is willing to invest because they know that advertising increases their sales in your channel.
To maximize this dual revenue, it is essential to choose your advertising partners carefully. Prioritize suppliers whose products are complementary to your offering and who have high sales potential with your audience. Rigorous selection allows you to create a virtuous circle where advertising benefits all parties.
What are the hidden costs of retail media?
Although retail media offers high margins, it comes with hidden costs that must be anticipated. Advertising content production, advertiser relationship management, and the technology required to deliver and measure campaigns can represent significant investments.
The sales and production costs of a sponsorship can reach 20% to 30% of advertising revenue, as in the previous example. You must also budget for the costs of contract management, billing, and performance tracking. These costs, although lower than those of selling products, must be factored into your profitability analysis.
To minimize these costs, automate your advertising processes as much as possible. Use campaign management and reporting tools to reduce manual labor. Effective management allows you to maximize your margins and make your advertising offer more competitive.
How to measure the performance of your retail media campaigns?
Performance measurement is essential to justify your advertising rates and optimize your campaigns. Key indicators include the number of impressions, click-through rate, cost per click, and especially the return on investment for your advertisers.
For your advertisers, the return on investment is measured in sales generated by the advertising. You must be able to track conversions attributable to each campaign, using tracking codes or dedicated links. This transparency is crucial for maintaining the trust of your partners.
Internally, measure the contribution of each campaign to your overall margin. Compare advertising revenue to production and management costs to calculate your net margin. Use this data to adjust your rates and formats, and to identify optimization opportunities.
Which ad formats should you prioritize for your audience?
The choice of advertising formats depends on your audience and your communication channels. Sponsored newsletters are an effective format because they reach an engaged and loyal audience. Banners on your search pages and category pages are also relevant, as they capture visitors in the purchasing phase.
Sponsored buying guides are another interesting option. They allow your suppliers to highlight their products in an editorial context, which reinforces their credibility. Placements on your product pages, such as complementary product recommendations, can also be monetized.
Test different formats to identify those that generate the best return for your advertisers while preserving the customer experience. A balanced approach allows you to maximize your advertising revenue without harming your customer satisfaction.
How to integrate retail media into your global marketing strategy?
Retail media should not be an isolated activity, but an integrated component of your overall marketing strategy. It is about monetizing your audience while strengthening your relationship with your suppliers and improving the customer experience.
Integrate retail media into your content strategy by offering sponsored placements in your newsletters and buying guides. Use your customer data to target ads and make them more relevant. This approach increases the value of your advertising inventory and improves results for your advertisers.
Retail media can also complement your paid advertising efforts. By monetizing your existing audience, you reduce your reliance on external advertising channels and increase your overall profitability. An integrated strategy allows you to maximize your revenue while strengthening your positioning.
