Measuring Success in Retail Media Advertising

Retail media is now a strong, measurable tool for brands and retailers in today's shopping landscape. As shopping shifts easily between online and in-store, it is crucial to understand what drives performance and how to measure it.

Retail media helps brands connect with consumers who are ready to buy. It also gives retailers a new way to earn money from their data and online shelf space. Success isn’t just about running ads or filling placements. It’s about understanding what works and what doesn’t. It’s also about how each campaign helps long-term growth.

‍

The Evolving Retail Media and Commerce Media Landscape

Retail media sits at the intersection of advertising, commerce, and technology. It includes search and display ads on a retailer's website. It also includes personalized product recommendations in an app. Recently, this area has changed into what we call commerce media. This system links advertising and shopping data across different channels. It helps brands and retailers see the entire journey from awareness to purchase.

For retailers, commerce media is not just a revenue stream—it’s a strategic capability. For brands, it’s a way to reach high-intent shoppers directly, supported by accurate data and transparent reporting. Platforms like Topsort help retailers grow their media businesses. They offer flexible tools, automated auctions, and privacy-focused technology. The focus is shifting from managing scattered networks to creating clear, measurable systems that work for everyone involved.

Why Measuring Success Matters

The growth of retail and commerce media has been explosive—but with growth comes complexity. As campaigns span multiple channels and data sources, it’s no longer enough to just look at clicks or impressions. Retailers need to show measurable value to their advertisers. Brands need to see how their investments translate into actual sales. And both sides need to understand the additional impact—the exact lift that retail media generates beyond organic performance.

Ultimately, measurement is what turns a retail media program from a test into a business. The foundation for smarter bidding, better targeting, and long-term partner trust exists.

The Core Metrics That Define Retail Media Performance

When looking at performance, these are the key metrics. This applies to both retailers running ad programs and brands investing in them.

‍

1. Return on Ad Spend (ROAS)

ROAS measures the revenue generated for each dollar spent on advertising. A healthy ROAS shows that ads are reaching the right retail audiences and driving real conversions, not just impressions.

2. Conversion Rate

This is one of the clearest indicators of effectiveness. Retail media placements, especially sponsored products, are very close to the point of purchase. Even minor improvements in conversion rates can significantly impact sales.

3. Click-Through Rate (CTR)

CTR helps evaluate how engaging and relevant the ad creative is. While it may not reflect final sales, it is a strong sign that targeting and messaging align with what shoppers want.

4. Customer Acquisition Cost (CAC)

CAC measures the total cost to acquire a new customer. In well-optimized retail media systems, automation and clean data can help lower customer acquisition costs. This also keeps conversion performance strong.

5. Extra Sales Impact

This measures whether the campaign actually led to more sales or if those shoppers would have purchased anyway. It helps show the real impact of your retail media investment.

6. Share of Voice and Category Insights

Tracking your brand’s position in a category helps you spot areas for improvement. It’s not just about being seen; it’s about reaching the right retail audiences at the right time.

Measuring What Matters: From Data to Decisions

Retailers and brands often have extensive campaign data. However, turning that data into valuable insights needs structure, alignment, and clean systems.

A few guiding principles make all the difference:

• Start with clear goals. Are you driving sales, awareness, or loyalty? Aligning metrics with objectives helps ensure reports are meaningful, not just long.
• Combine short- and long-term KPIs. Balance immediate performance metrics, like ROAS, with broader indicators, like repeat purchase rates.
• Use first-party data responsibly. As privacy regulations tighten, relying on retailer-owned data allows for both personalization and compliance.
• Adopt adaptable infrastructure. Clean, modular systems make it easier to measure across channels and adjust strategies in real time.

At Topsort, these ideas guide how we help retailers and marketplaces make sense of their data. By automating auction processes, unifying performance tracking, and supporting privacy-focused measurement, retailers can focus more on results and less on manual reporting.

Retailers around the world are building sophisticated ad ecosystems that reflect the new era of commerce media.

• Amazon Ads is a leader in retail media. They offer many options, including sponsored ads, video, and display campaigns. First-party shopper data powers all of these.
• Walmart Connect: Integrating online and in-store campaigns to deliver unified measurement across channels.‍
• Target Roundel: Focused on delivering relevant ads to verified audiences, blending media and retail data for measurable performance.
• Tesco Media & Insight and Coles 360 are leaders in omnichannel retail media. They connect e-commerce, loyalty programs, and in-store measurement.

These examples show how retailers use flexible, data-driven methods. They often rely on modular or API-based technology to grow faster and show clear ROI.
