Retail media may provide ecommerce retailers with high-margin revenue from an audience they have paid to attract.
Merchandise sales from online and even brick-and-mortar retailers often produce gross margins near 50%, contribution margins of 25%, and net profit approaching 12%.
Retail media margins can look much higher because merchants have incurred much of the cost of attracting shoppers. Plus, the ad buyers are often a store’s suppliers.
Products vs. Ads
Here is a comparison.
Selling a $100 product might leave $25 after cost of goods sold, fulfillment, payment processing, shipping, and other variable costs — a 25% contribution margin.
A $1,000 newsletter sponsorship has no comparable cost or return risk. Ancillary expenses such as sales commissions, creative, and technology may total $250, leaving $750 before general overhead — a 75% contribution margin.
Large retail media networks have reported similarly attractive economics. In 2022 both McKinsey & Company and Boston Consulting Group estimated operating margins from those networks at 70% and more.
Existing Audience
Conceptually, retail media resembles advertising in the publishing industry.
A publisher attracts readers with articles, newsletters, videos, or other content and then sells advertisers access to that audience.
An ecommerce merchant attracts shoppers with products and services. Retail media monetizes the audience a retailer already has.
Consider a specialty retailer that sends four monthly newsletters to 40,000 subscribers.
A supplier agrees to pay $1,500 per month for a recurring sponsorship, hoping to drive 400 additional product sales. Selling and producing the sponsorship costs $300 per month. Thus the placement contributes about $1,200 before general overhead, or an 80% contribution margin.
The merchant emails its existing audience of subscribers.
The same logic applies to search results pages, category pages, buying guides, and other sections.
Purchase Intent
A retailer’s audience can be more valuable to advertisers than a mainstream publisher’s because shoppers are closer to a purchase.
A publisher might know that a visitor reads hiking articles. An outdoor retailer, by contrast, knows that same person searched for waterproof hiking boots, viewed several pairs, and purchased hiking socks six months ago.
That difference matters to advertisers, who are buying access to shoppers with commercial intent.
Supplier, Buyers
Supplier-funded advertising is not new to retail. Co-operative programs from suppliers have long subsidized ads that promote their products.
Retail media extends that relationship. Instead of sharing the cost of external ads, suppliers can pay the retailer directly for access to its audience.
For ecommerce merchants, it’s potentially a new revenue source from companies they know and work with.
A 2025 TransUnion study reported that 70% of retail media spending was incremental to suppliers’ broader trade budgets, meaning retail media generates new money rather than moving from one bucket to another.
Double-Dip
One final point. When the retail media buyer is a supplier, the ecommerce shop earns twice: once from ad revenue and again from higher merchandise sales.
The setup echoes co-op campaigns. The supplier wants to sell in the retail channel and doesn’t mind investing in advertising, even when the retailer gets to double-dip, profit-wise.
