You’re on amazon.com, checking the product page for one of your brand’s best-selling items.  

Then you spot it — a competitor’s ad for a similar item, complete with a discount code and free shipping. 

Exactly how did a rival brand get its ad and special offer in front of an Amazon shopper looking at your product?  

It’s called retail media advertising, and it’s changing digital advertising to the tune of billions in ad spend from both B2B and B2C brands. Read on to learn what it is, how it works — and if it could be right for your marketing strategy. 

How Does Retail Media Advertising Work?

To put it simply, retail media advertising places ads right on retailers’ digital channels, such as their websites or apps, where consumers are shopping. Think of it as the online equivalent of those on-shelf coupon dispensers or point-of-purchase displays you see in brick-and-mortar stores.  

Instead of aisles and endcaps, these e-commerce ads show up on retail media networks, which sell ad space on their digital channels to third-party brands. The most common retail media networks are Amazon Advertising, Walmart Connect, Target’s Roundel, and Best Buy’s Retail Media+.   

Retail media advertising is so exciting to brands because it lets them reach consumers who are actively shopping online. Consumers who are already in a purchasing mindset tend to have a higher likelihood of buying compared to those still considering. Through retail media, brands can show shoppers ads that are personalized and targeted with messages intended to sway their decision at a key moment in the purchase funnel. In short, retail media and specific keyword targeting help us get in front of the right people, at the right time, with the right ad.

That access and targeting are driving rapid growth. According to a fall 2023 report from Live Ramp, retail media ad spend has more than doubled in the last three years, increasing from $20.91 billion in 2020 to $45.38 billion in 2023. That amount is expected to more than double by 2027, up to $107 billion, the report found. 

Who Does Retail Media Advertising Work For?

Retail media advertising has been considered a key tactic for B2C brands, but it can be successful for B2B brands as well. For example, retailers like Office Depot cater to business customers who shop online to order products or services for their day-to-day operations.  

B2B brands can also benefit from retail media advertising by increasing their brand awareness, driving purchases among business customers, and generating leads. 

A Retail Media Success Story: 275% Return on Ad Spend

At Brunner, we’re helping B2C and B2B brands use retail media to drive purchases and ultimately grow their business. 

For example, we’ve worked with a client in the consumer health and personal care industry to steadily increase their retail media spend over the past year. This client did not have the ability for direct-to-consumer purchasing on their website, making it difficult to measure the impact of media buys on sales.  

By using retail media — in this case, Walmart Connect — the Brunner team could easily reach customers across the buying funnel, then measure conversions effectively, using Walmart’s shopper data. This client’s sponsored product campaigns are reaching up to a 275% return on ad spend (ROAS). 

What Are the Benefits of Retail Media Advertising?

Retail media can play a key role in an integrated media plan to complement and enhance other media channels. While there are many benefits of retail media networks, two stand out as the biggest reasons to include retail media in your marketing mix. 

1. Showcasing Products on Prominent Retailer Platforms

One of the biggest advantages of retail media is giving brands a way to showcase their products and messaging prominently on high-traffic e-commerce websites like amazon.com, walmart.com, and target.com. These retailers get a significant amount of traffic and purchases, every single day, around the world. By advertising on the websites or apps of key retailers, brands can drive incremental sales by putting ads where customers are already shopping. Content that works well on retail media networks often highlights value, including key product or price differentiators, and credibility. 

2. Using First-Party Data, not Cookies, to Target Audiences

The continuing move to cookieless marketing is creating a growing need to use first-party consumer data. Retail media networks collect first-party data from consumers who purchase through their marketplaces. This first-party data can then be leveraged for advertising within the retail media network to target prospects and existing customers efficiently.  

Using first-party data for targeting provides brands with clear, reliable performance data and insights that can guide future adjustments. The goal is to improve results and drive impact continuously. 

How Does Retail Media Network Ad Placement Work?

In retail media networks such as Amazon Advertising, there are three main strategies when placing an ad. 

Offensive ads are campaigns that show on competitor product detail pages. This is a very common tactic as it can persuade users to purchase the advertiser’s product instead of a competitor’s. 
 

Defensive ads are campaigns that show another of a brand's products on their own advertisement or product page. This capitalizes on the hope that if a customer is interested in one of a brand's products, perhaps they’d be interested in another as well.  
 

Display ads on a retail media network blend brand messaging with retail features to sway a customer into exploring a product or brand.

What Should Be a Brand’s Goal with Retail Media Ads?

Retail media networks offer various ad formats, including sponsored products, display ads, video ads, and more. These options mean retail media ads can be used to target different customers at different stages of the marketing funnel. Here’s how it works. 

  • Retail media campaigns can help advertisers build awareness by reaching new customers who — based on their consumer behavior — may not be familiar with what the brand offers.  
  • Once consumers are familiar, targeted retail media ads can help advertisers influence potential customers who are exploring options and are already interested in what they sell.  
  • Finally, retail media campaigns can help brands land the sale from customers who are ready to buy, delivering the ultimate marketing goal — driving purchases.
