How to select a commerce media network partner

Hiring the wrong person for an open role costs you more than the salary. It costs you the ramp-up time, the redone work, and the opportunity you missed while they were figuring things out. Picking a commerce media network partner works the same way. The wrong fit doesn't just waste ad spend, it can also delay your team from understanding whether the channel works for your brand at all.

That's worth taking seriously, because commerce media has become a high margin revenue stream for retailers and brand partners alike, and it's opening new revenue streams for brands who get the partnership right. Getting it right the first time means you spend your budget learning what works instead of learning what your partner can't do.

Key takeaways

• Commerce media networks extend the retail media model beyond a single retailer's own site to other digital channels and physical stores.
• Not all commerce media is retail media. Retail media refers specifically to ads sold on a retailer's owned properties, while commerce media networks and broader retail media networks can include online travel agencies, delivery platforms, and other commerce touchpoints.
• Strong first-party data, from purchase history to loyalty program behavior, is the foundation of any retail media solution worth paying for.
• Closed loop measurement claims deserve a second look, since a network reporting on its own campaign performance has an obvious incentive to report favorably.
• The best commerce media networks integrate with your existing tech stack and offer test-and-learn opportunities before you commit long term.
• Watch for red flags like vague "secret sauce" claims, and look for green flags like case studies from brand partners similar to your own.
• An independent view of performance, like a marketing mix model, helps you confirm whether a network's reported numbers hold up against your actual revenue.

Start with your goals and your audience

Before you look at a single network, get specific about what you're trying to accomplish. Are you trying to drive sales at the point of purchase, build awareness with new audience segments, or get in front of shoppers who've never heard of your brand? Each goal points you toward different networks, so skipping this step means you'll end up evaluating options against no real standard.

Once you know your goal, think about where your audience actually is. A consumer packaged goods brand might find its most relevant audiences on a grocery retailer's mobile apps, while a brand with a higher price point might do better reaching high intent shoppers through a broader media network with connected TV or off site placements. Either way, the goal is the same: reach consumers who are close enough to purchase that the ad actually moves them. A few questions worth asking yourself:

• Do you want to reach consumers who are actively searching for a product like yours, or build demand with people who aren't looking yet?
• Does your ideal customer shop across multiple channels, or are they loyal to one or two retailers?
• Would sponsored placements on a retailer's site do more for you than targeted ads that follow shoppers across digital channels?

Answering these honestly narrows your options fast, and it keeps you from signing with a network because it's popular rather than because it's the right fit.

What actually counts as a commerce media network

Retail media refers to a specific type of digital advertising sold directly by a retailer on properties it owns, like sponsored product listings on a product detail page or search ads within its own app. A commerce media network (CMN) takes that same idea and extends it further. Instead of limiting ad space to one retailer's site, a CMN brings together digital advertising across multiple channels, including online travel agencies, delivery platforms, and even physical stores through digital shelf placements. Many of these networks are run in partnership with media companies that bring their own audiences and ad inventory to the table.

Not all commerce media is retail media, and treating the terms as interchangeable can lead you to the wrong kind of partner. If your goal is narrowly focused on a single retailer's shoppers, a retailer's media network built around that retailer's own first-party data might be the better fit. If you want broader reach across traditional retailers, delivery apps, and other brands' properties, you're looking for a true commerce media network, or one of the broader retail media networks that have started operating across multiple retail partners at once.

Sponsored ads and ad placements take a few different shapes depending on the network, and pricing usually varies across ad formats too, so here's a quick breakdown of how those ad formats typically differ:

Understanding these ad formats before you start vetting partners helps you ask sharper questions, since a sales rep can talk in generalities about "reach" without ever explaining which formats you'd actually be buying, which matters more as third party cookies disappear and first-party data becomes the main way networks target the right shopper. That programmatic advertising layer is often what lets a network follow shoppers off site in the first place, so it's worth understanding before you commit budget to it.

Evaluate the network's first-party data and reach

A commerce media network is only as good as the data behind it, which is why the strongest retail media solution options are built around verified first-party data rather than guesswork. Since third party cookies keep breaking down, a network's own first-party data, built from real purchase history and transaction data, is what makes its targeting worth paying for. Ask any partner you're considering how they collect and maintain that first-party data for advertising purposes, and whether it comes from actual customer behavior or from broader assumptions about audience segments. The retail media insights a network shares with you are only as trustworthy as the data collection process behind them, so don't be afraid to ask how that process actually works.

A few things worth confirming before you commit:

• Data collaboration: Does the network let you combine your own customer data with their retailer first-party data to build more relevant audiences, or do you have to rely entirely on their audience insights? Real data collaboration means you both bring something to the table, and the network should be able to explain exactly how your data gets blended with their retailer first-party data without either side giving up control of its own audience insights.
• Reach: Does the network's scale match your category, and is its data collaboration model flexible enough to fit how you already work? A network built for consumer packaged goods brands might not have the ad inventory you need if you sell higher consideration products.
• Commerce data depth: Does the network provide behavioral data beyond a single transaction, like repeat purchase patterns and transaction data over time, or just a snapshot of one sale?

Brands sometimes assume more consumer data automatically means better targeting, but raw customer data without a clear structure for using it doesn't help you engage shoppers any better than a smaller, well-organized data set would. Ask for specifics rather than taking "we have access to first-party data" at face value.

Look past the dashboard: how the network measures performance

This is where a lot of brands get burned. A network's dashboard will show you campaign performance in the best possible light, because that dashboard is built by the same company selling you the ad space. It's not that these numbers are made up, but they're reported by the network measuring itself, and that's a different thing than an outside view of what actually happened.

Ask specifically how the network defines a conversion, and whether that definition accounts for the full customer journey or just clicks that happened within their own walled garden. Closed loop measurement sounds appealing on paper, since it promises to connect media impressions directly to purchase behavior, but "closed loop" also means the loop doesn't extend past that network's own data. If a shopper saw your ad on the network, then bought later through a completely different channel, most networks won't give themselves credit for that because they can't see it, even though your marketing efforts are the reason the sale happened.

This is exactly the kind of question an independent marketing mix model is built to help answer. Rather than relying on any single platform's closed loop measurement, an MMM looks at your actual revenue and works backward to understand which marketing channels, including commerce media networks, are truly driving it. That approach helps brands confirm whether a network's reported ad spend efficiency matches what's happening across their whole business, not just what shows up in their dashboard.

A few questions to bring to any sales conversation:

• How do you define and measure a conversion?
• Can I see performance broken down by campaign, not just in aggregate?
• What happens to attribution when a shopper interacts with multiple marketing channels before purchasing?

Vet the partnership, not just the platform

Great commerce media networks pair strong technology with a team that actually understands your business. It's easy to get sold on the platform and forget to evaluate the people who'll be running your advertising campaigns day to day, so treat this step with the same rigor as anything else on this list. Here are a few of the key challenges brands run into when vetting a partner, and how to spot them before you sign anything.

Green flags to look for:

• The team asks detailed questions about your business, your goals, and your current marketing channels before pitching anything
• They can point to case studies or results from other brands in your category or of a similar size
• Reporting is transparent enough that you can see how numbers are calculated, not just the final total

Red flags to watch for:

• Vague claims about proprietary technology or a "secret sauce" with no real explanation of how it works
• Promises of results that sound too good to be true relative to your ad spend
• A strong sales team that hands you off to a completely different, less experienced team once the contract is signed

It's also worth resisting the urge to launch on every available network at once. Focusing your budget on one or two networks that fit your goals, proving out results, and then expanding tends to work better than spreading a limited budget thin across five different commerce media networks in your first quarter.

Check tech integration and support

A commerce media network that doesn't fit into your existing tech stack creates extra work for your team every single week. Before signing anything, confirm how the network's platform connects to the tools you already use to plan and optimize campaigns, and whether that integration requires ongoing manual work or update it automatically.

A few practical things to check:

• Does the network offer a pilot period or test-and-learn phase as a low-risk entry point before asking for a long-term commitment?
• Will you have a dedicated point of contact who understands your account, or a rotating support queue?
• How easily can you pull data out of their platform if you ever need to switch partners?

Commerce media networks that make this process easy are usually more confident in their own results, since they're not relying on switching costs to keep you as a customer. A network built on solid revenue streams of its own tends to compete on performance rather than on how hard it is to leave.

Where Prescient comes in

Choosing the right commerce media network partner is only half the equation. The other half is knowing whether that partnership is actually working once you're live, and that's harder to answer than most dashboards let on. Prescient's marketing mix model gives you an independent view of how each of your marketing channels, including commerce media networks, is contributing to revenue across the full customer journey, complete with retail halo effects that show how a campaign on one channel can help you reach consumers who ultimately convert somewhere else entirely.

That means you're not stuck relying on a network's own reporting to know if it's worth the ad spend. You get a clear, unbiased picture that helps you decide where to scale and where to pull back. If you want to see how that works, book a demo with our team.

FAQs

What is a commerce media network?

A commerce media network is a platform that sells advertising across multiple commerce touchpoints, not just a single retailer's website. That can include a retailer's own app, delivery platforms, online travel agencies, and other digital channels, all powered by first-party data collected from actual shopper behavior.

What's the difference between a commerce media network and a retail media network?

Retail media refers specifically to advertising sold on a retailer's own properties, like sponsored product listings on their site or app. Retail media networks are typically tied to one retailer, while a commerce media network is broader, bringing together ad inventory from multiple retailers, delivery platforms, and other digital properties into one buying experience. Every one of these retail media networks is a piece of the commerce media landscape, but not all commerce media is retail media.

How much budget do you need to start with a commerce media network?

There's no universal minimum, since it depends heavily on the network and your category, but most brands see more reliable insights once they've spent enough to gather meaningful data on campaign performance. Starting with a modest test budget on one or two campaigns is usually a smarter first move than spreading a small budget across many networks at once.

How do you measure ROI from commerce media network spend?

Most networks will show you their own reported ROI through their dashboard, but that's only part of the picture, since it typically only captures activity within their own platform. Pairing that reporting with an independent measurement approach, like a marketing mix model, gives you a fuller view of how commerce media spend affects your total revenue, including any halo effects on other channels.

Can small or mid-size brands work with commerce media networks?

Yes, many commerce media networks offer entry points designed for smaller ad spend, especially self-serve platforms that don't require a large minimum commitment. Smaller brands should pay close attention to first-party data quality and reach, since a smaller network may not have enough scale within a specific category to justify the cost.

How long does it take to see results from a commerce media network partnership?

Timelines vary by category and goal, but most brands need at least a few weeks of consistent spend before campaign performance data becomes reliable enough to act on. Give a new partnership enough runway to gather real data before deciding whether to scale it up or move on.
