Retail Media ROI for CPG Suppliers

Retail media is having a moment.

Actually, that undersells it.

U.S. advertisers spent $60.32 billion on retail media in 2025, and eMarketer forecasts that number will rise to $71.09 billion in 2026. IAB says commerce media remains the fastest-growing digital advertising channel, even as growth begins to mature. In other words, this is no fad. It is now a serious line item in the supplier budget.

And that is exactly why suppliers need to slow down and think.

Because retail media can absolutely help. It can improve visibility, support new item launches, reinforce promotions, and help brands win the digital shelf. But it can also become a very expensive way to create activity without real incrementality. More impressions do not automatically mean more profitable sales. More clicks do not automatically mean stronger item productivity. And more sponsored placements do not fix weak content, poor in-stock position, or a product that never had the right pricing architecture to begin with.

That is the trap.

Here is a fictional example that feels familiar: a snack brand gets excited about a retail media package tied to a seasonal event. The retailer offers sponsored search, banner placements, and off-site support. The supplier says yes because it feels like momentum. But the product detail page is weak. Reviews are light. Inventory is inconsistent. The featured SKU is not even the best one for conversion. The campaign runs. Money gets spent. The recap deck looks polished. Yet the margin story gets uglier.

That happens more often than people like to admit.

What makes this even more interesting is where retail media is heading next. It is not just digital shelves and sponsored search anymore. eMarketer reports that retailers like Kroger, Albertsons, and CVS are expanding in-store media networks, adding digital screens and new measurement tools to monetize shopper traffic closer to the point of purchase. But there is a catch: measurement remains one of the biggest barriers. Even eMarketer notes that in-store retail media remains a small share of total retail media spend, and retailers are still working to demonstrate true incrementality.

That matters for suppliers because the burden of discipline usually falls on you.

So before spending another dollar, start here:

First, define the job. Are you trying to launch a new item, protect an existing one, support a promotion, or improve search conversion? “Drive awareness” is not enough. If the objective is fuzzy, the spending usually is too.

Second, make sure the shelf is ready before the media is. If your content is weak, your images are inconsistent, your item is out of stock, or your ratings are thin, the media may only amplify the problem.

Third, choose the SKU carefully. Not every item deserves support. The best retail media candidate is often the item with a strong conversion path, a healthy margin structure, and a real reason to win in search or on-shelf.

Fourth, demand a readout that connects spend to business performance. Not just impressions. Not just clicks. Look for lift, incrementality, repeat behavior, basket effect, and what happened after the campaign stopped.

This is where many suppliers need to become more ruthless. Retail media should not be treated like a participation trophy. It should earn its place the same way any other investment does.

Spend where the math works. Pause where it does not. And do not confuse retailer enthusiasm with supplier ROI.

Retail media can be powerful. It can also serve as a polite way to transfer margin from the supplier's P&L into the retailer ecosystem.

The best suppliers know the difference.

At Woodridge Retail Group, we think retail media works best when it supports a real retail strategy, not when it becomes the strategy. That distinction sounds small. It is not. It is often the difference between growth and expensive motion.
