Retail media is eating the funnel, and mid-market brands are the ones most likely to overpay for it.
Key takeaways
- A retail media strategy for mid-market brands should start with a short list of networks tied to where your buyers actually convert, not with every network that offers you a dashboard.
- Retail media is no longer just Amazon. Retailers, grocers, delivery apps, and marketplaces now sell ad space against their own first-party purchase data.
- The most common mistake is paying for reach you already had: bidding on your own branded terms and shoppers already in your cart.
- Measure incrementality, not just attributed sales. A sale a retail media network claims is not always a sale it caused.
- A net 38% of marketers plan to increase retail media spend in 2026, per Amazon Ads, so competition for the same placements will rise.
Retail media is the fastest-growing line in most commerce budgets, and a retail media strategy for mid-market brands now decides how much of that spend turns into new demand instead of rented credit for sales you would have won anyway. Retail media networks (RMNs) sell ad placements against a retailer's first-party purchase data, which means you can reach a shopper at the moment of intent. That precision is real. It is also easy to buy badly.
Alive Method is a marketing and advertising company. We build these programs for brands that have outgrown guesswork but do not have a 40-person commerce team, and the pattern we see most often is spend rising faster than proof. This post covers three things: where mid-market brands should actually play, how to stop paying for reach you already had, and how to measure retail media honestly.
What is retail media, and why is it no longer just Amazon?
Retail media is advertising sold by a retailer against its own shopper and purchase data, placed on its site, app, or in its stores. Amazon Ads built the category, but the model spread. Grocers, big-box chains, delivery apps, drugstores, and marketplaces now run their own networks, so commerce media is a field of options, not one storefront.
The shift matters because each network reaches a different buyer at a different moment. A shopper searching a grocery app is close to purchase. A shopper browsing a big-box home page is earlier. When every retailer sells its own inventory, "retail media" stops being a single channel and becomes a portfolio decision. Mid-market brands feel this most, because they cannot fund all of it and still have to pick.
Commerce media also blurs the old line between upper and lower funnel. Onsite search ads capture intent. Offsite and in-store placements build awareness against the same purchase data. The funnel is not gone. It is compressed into fewer clicks and owned by the retailer.
Where should mid-market brands actually play?
Play where your buyers already convert, then expand one network at a time. For most mid-market brands that means starting with the one or two retailers driving the majority of sales, winning there with clean product data and defensible bids, and treating every additional network as a test with its own budget and its own exit criteria.
The temptation is to be everywhere at once. Resist it. A mid-market budget spread across six networks funds six mediocre programs. The same budget on two networks funds two you can actually manage, measure, and defend. Use this rough sort to decide where a network sits for you.
| Network type | Best for | Watch for |
|---|---|---|
| Marketplace (e.g. Amazon Ads) | Scaled search intent, product discovery | Branded-term overspend, crowded auctions |
| Big-box retailer RMN | Category shoppers, in-store plus online | Minimums, data access limits |
| Grocery and drugstore RMN | High-frequency, close-to-purchase demand | Small basket sizes, narrow reporting |
| Delivery and app networks | Convenience-driven, impulse purchase | Thin incrementality proof |
Pick the row that matches where you win today. Fund it properly. Add the next row only when the first is measured and holding.
How do you avoid paying for reach you already had?
Separate demand you create from demand you capture. The most expensive habit in retail media is bidding hard on your own branded terms and on shoppers already holding your product, then counting those sales as wins. You paid for a click on a purchase that was already going to happen. That is reach you already had.
Three moves keep this honest:
1. Cap branded-term spend. Bid enough to defend the placement from competitors, not enough to buy clicks you would win organically. Test going dark on branded terms for a short, controlled window and watch what actually drops.
2. Watch the audience overlap. Retargeting a shopper who is already in the cart is not new demand. Push budget toward prospecting audiences and categories where you are not the default choice.
3. Read the placement, not just the platform. A sponsored slot at the top of a page a shopper reached by searching your brand is defensive. A slot in a competitor's category is offensive. Fund the offensive ones first.
None of this means abandon branded coverage. It means know which portion of your spend is defense, price it as defense, and stop calling it growth.
How do you measure retail media honestly?
Measure incrementality, not just attributed sales. An RMN reports the sales it can claim, which counts conversions it may not have caused. Honest retail media measurement asks a harder question: how many of these sales would not have happened without the ad? Answer it with holdout tests, geo experiments, and new-to-brand metrics, not the platform's self-graded total.
Attributed revenue and return on ad spend are useful as directional signals and useless as the whole story, because the network scoring itself has every reason to claim credit. The fix is not distrust. It is a second lens: a control group that did not see the ad, so you can compare. Where a network offers new-to-brand reporting, weight it, because acquiring a first-time buyer is worth more than nudging a loyalist.
Set the standard before the campaign, not after. Decide which metric proves the program worked, agree on it, and hold the reporting to it. Full-funnel programs make this easier, because upper-funnel activity shows up in lower-funnel lift you can actually track.
How Alive Method approaches this
We treat retail media as one part of a system, not a standalone buy. The Alive Method System runs in order: Understand, Design, Express, Enable, Evolve. That means we start with where a brand actually converts and what a win has to look like, then build the program and the measurement together so the numbers mean something when they arrive.
For Ancient Nutrition, we ran a store-level Target activation that drove 708,000 impressions across 50 stores, pairing localized advertising with the in-store moment rather than treating them as separate budgets. For DecoArt, we ran Google Shopping and Performance Max inside a full-funnel program, so upper-funnel demand and lower-funnel capture were measured against each other instead of in isolation. In both cases the point was the same: know which spend created demand and which spend caught it. Applied AI supports this work, helping us model incrementality and spot overlap faster, but the discipline is the strategy, not the tool.
FAQ
What is a retail media network (RMN)?
A retail media network is a retailer's own advertising business. It sells ad placements on its site, app, and sometimes in its stores, targeted using the retailer's first-party shopper and purchase data. Amazon Ads is the largest, but most major retailers now run one.
Is retail media only worth it for large brands?
No. Mid-market brands can compete because retail media rewards clean product data, disciplined bidding, and honest measurement more than raw budget. The risk is spreading a smaller budget too thin across too many networks instead of winning on one or two.
How much of my retail media spend is wasted?
Often the portion aimed at demand you already had: branded-term bids and shoppers already set to buy. You cannot know the exact figure without testing, which is why holdout and geo experiments matter. Start by separating defensive spend from growth spend.
How is retail media measurement different from standard digital attribution?
Standard attribution counts conversions a channel can claim. Retail media measurement done well asks whether the ad caused the sale, using control groups, geo tests, and new-to-brand metrics. The network's own reported total is a starting point, not a verdict.
Should I move budget out of Amazon Ads into other networks?
Not automatically. Move budget when another network reaches buyers you are not converting today and can prove incremental sales. Amazon Ads often remains the anchor for search intent. Treat every additional network as a funded test with clear exit criteria.
