How to Choose Retail Media Platforms: A Selection Framework for CPG Marketing Teams
A retail media network is a retailer's advertising business: brands pay to reach shoppers on the retailer's own site, app and stores, guided by the retailer's shopper data. Amazon, Walmart, Target, Instacart and Kroger all run one, and CPG marketing teams keep asking the same question. Where do we advertise first, second and third?
This guide lays out the framework we use with our CPG clients: a six-factor scorecard, a worked example and simple rules for where to start.
Key Takeaways
Six factors rank the networks: shopper overlap, category fit, audience and data access, ad formats, measurement quality and minimum effort.
Shopper overlap and category fit set the order. Measurement quality sets how fast you can learn.
Base your scores on your actual sales mix and team capacity instead of chasing a network's total reach.
Most CPG brands do well starting with one or two networks and adding a third once measurement is in place.
A cross-retailer view keeps budget, bidding and reporting consistent as the list grows.
Why Choosing Retail Media Platforms Is Harder Than It Looks
Each retail media platform sells its own mix of ad formats, buying models and measurement. Amazon sells sponsored ads by the click with no minimum spend. At Target, display runs as a managed service while programmatic runs through your own DSP. Side by side, the options rarely line up.
In our client work, the harder problem is fragmentation. Every network adds another login, reporting format and set of bids, and few teams have the hours to run five networks well at once. Testing networks against each other is central to the retail media strategies we run, and it starts with deciding the order.
The Six-Factor Retail Media Scorecard
This scorecard ranks your retail media options using six weighted criteria tailored to your growth targets.
What Each Factor Measures
Each factor answers one plain question:
Shopper overlap: How many of your best customers shop this retailer? Use your own sales and household data.
Category fit: How well do this retailer's shoppers buy your category? Look at sell-through and category share.
Audience and data access: What targeting and first-party data does the network let you use?
Ad formats: Does the network offer the formats you need, such as search, display, video or in-store?
Measurement quality: Can you track closed-loop sales, run incrementality tests, and verify attribution accuracy?
Minimum effort: How much setup, budget and team time does it take to run well?
How to Score and Weight the Networks
Score each factor from 1 to 5, then assign a weight to each. A starting set of weights that works for many CPG brands:
Shopper overlap: 25%
Category fit: 20%
Measurement quality: 20%
Audience and data access: 15%
Ad formats: 10%
Minimum effort: 10%
Multiply each score by its weight and add them up for a total out of 5. Adjust the weights to your goals; a brand focused on learning fast might increase the measurement weight to 30%. Use the final scores to guide your rollout order, adjusting as real campaign data comes in..
A Worked Example: Scoring Five Networks
Here's the scorecard for a hypothetical shelf-stable snack brand. It sells mostly through Walmart and grocery stores, has a smaller Target presence, runs a lean team and is on Kroger shelves in two regions. Overlap, fit and effort come from that brand's profile; the other factors come from each network's published tools.
| Network | Shopper Overlap25% | Category Fit20% | Audience and Data15% | Measurement20% | Formats10% | Effort10% | Totalout of 5 |
|---|---|---|---|---|---|---|---|
| Walmart | 5 | 4 | 4 | 3 | 4 | 4 | 4.05 |
| Amazon | 4 | 3 | 4 | 4 | 5 | 5 | 4.00 |
| Instacart | 3 | 5 | 3 | 4 | 4 | 4 | 3.80 |
| Target | 3 | 3 | 4 | 4 | 3 | 3 | 3.35 |
| Kroger | 2 | 3 | 4 | 3 | 3 | 2 | 2.80 |
Walmart and Amazon finish within a few hundredths of each other, so either can lead, with Instacart a close third. Target and Kroger trail, mostly because this brand has less distribution there. Your own scores will differ.
Retail Media Network Comparison: Amazon, Walmart, Target, Instacart and Kroger
Each retailer operates its own ad platform: Amazon Ads, Walmart Connect, Target Roundel, Instacart Ads, and Kroger Precision Marketing.
| Network | Formats | How Brands Buy | Measurement | Published Scale |
|---|---|---|---|---|
| Walmart Connect | Sponsored search in a second-price, cost-per-click auction, display, offsite media and store ads | Self-serve or managed; $100 recommended daily minimum | Attributed sales and incrementality testing | 4,600+ US stores; about 150M customers weekly |
| Target Roundel | Product ads, search, CTV, display, programmatic, social and in-store | Managed display; self-service programmatic | Closed-loop, in-store and online | 100M+ Target Circle members |
| Instacart Ads | Sponsored products, display, shoppable video and recipes | Self-serve or through partners | Sales lift testing; MRC-accredited metrics | 55M+ consumers |
Figures are each network's own, as published in November 2026.
Where to Start by Brand Profile
When two scores are close, these rules break the tie:
Sales concentrated at one retailer: Start there, where your products already sell.
Strong direct and Amazon presence: Start with Amazon, then add a retailer network once measurement is in place.
Grocery-led distribution: Start with the grocery network that best fits your category, then add a mass retailer.
Small team and budget: Pick one network and one objective, and run it well before adding another.
New distribution or a product launch: Let the retailer's rollout plan set the order.
How to Sequence Your First, Second and Third Networks
Run your top-scoring network first. Add the second once its reporting works, and the third when the first two are stable. Rescore every quarter as distribution, budget and results change.
Measurement quality often sets the pace. A network where you can run incrementality tests shows what each dollar adds, so it teaches you more, sooner.
As the list grows, one plan across every network keeps budgets, bids and reporting consistent. We've run CPG retail media programs this way, with one senior strategist planning every network.
Conclusion
Choosing retail media platforms gets easier with a consistent method. Score each network on six factors, start with your top one or two and rescore every quarter. Our CPG marketing agency, we run this scorecard across Amazon, Walmart, Target, Instacart and Kroger.
