Brands are enthusiastic about using retail media networks (RMN) to reach their audiences. Ecommerce brands and retailers capture astronomical amounts of traffic each month. SEMRush reports that Amazon's ecommerce site gets 2.01 billion visits per month, and Walmart sees about 400-500 million visitors per month. While that traffic is good news for those enterprises and their third-party partners who sell there, it also represents an opportunity for advertising partners to get in front of an audience that's ready to buy via a retail media network. However, the opportunity isn't only advertising on retail media online. RMN are increasingly expanding to enable advertising in physical stores.
According to Gartner, a retail media network is a packaged retail website search, display, app, in-store assets and other digital advertising opportunities (e.g., ad impressions) that are sold to brands and advertisers. Retailers leverage media networks to execute their unified retail commerce strategy and to develop new lines of revenue, while advertisers aim to increase their exposure to and influence the behavior of retail shoppers at or near the final point of purchase.
Advertisers have evaluated RMN and have found three compelling reasons to use them to reach their audiences:
In addition to a competitive edge for advertisers, retail media networks also have advantages for the retailers who offer them. Most apparently, it helps retailers build a new revenue stream from advertising, more than offsetting the cost of the network's infrastructure and total cost of ownership.
However, retail media networks can also help brands use their data to increase revenue. Because the network integrates with the retailer's management system, the retailer can perform closed-loop measurements, linking ad impressions to actual sales, showing how valuable advertising on the network can be.
Learning from the retail media network can also help retailers optimize the shopping journey. Retailers can gain a better understanding of their customers' behaviors by taking both digital and physical activity into account. This intelligence can help retailers enhance shopping experiences and even place advertisers' merchandise more strategically to increase conversions, benefitting their advertisers and their own businesses.
In-store RMN solutions are most beneficial in high-traffic areas where stores display consumer packaged goods (CPG) in particular. Retail media advertising is also effective when it displays complementary products to what's on the shelf. Some of the best sites for retail media network advertising are:
Quad, a marketing services provider, points out that CPG marketers are "thrilled to be able to fish where fish are biting."
Retailers need the right hardware, software, and infrastructure to create an effective in-store retail media network system. Essential components include:
Gartner reports that in 2025, 30.6% of the total marketing budget across all industries went to paid media, which is an 11% increase on gross media spend as a proportion of company revenue year over year. Media networks have significantly proliferated in the last several years, forcing CMOs to manage a more fragmented media buying process that requires outside help, like agencies or ad-tech measurement solutions.
