The next challenge for data clean rooms

Data clean rooms (DCRs) have evolved from a technological curiosity to a standard marketing tool. Their competitive advantage now comes from knowing when they create real business value.

When Google Ads Data Hub launched in 2017, the industry’s focus was on privacy, secure collaboration, and vendor capabilities. In 2023, IAB Tech Lab published common principles and operating recommendations for data clean rooms, underscoring how mainstream the technology had become.

Since then, conversations about DCRs have centered on infrastructure: privacy protections, identity resolution, governance models, interoperability, and vendor capabilities. Now, they need to be about when a data clean room is the right tool for the business problem you’re trying to solve.

Every technology comes with tradeoffs

One reason this conversation matters is that DCRs aren’t another feature to turn on. They require investment, technical expertise, governance, collaboration, and time. Those investments are worth making for some business needs, but not all.

If a simpler approach delivers the same answer using existing reporting, syndicated data, or another measurement methodology, leaders should ask:

Does introducing a data clean room create incremental value or simply add incremental complexity?

Every technology decision carries opportunity costs. Every dollar invested, every engineering hour committed, and every month spent implementing infrastructure is time that’s not spent on higher-priority work. That’s why deciding when not to use a data clean room may be just as important as deciding when to use one.

We need better decision frameworks

Organizations work across increasingly complex ecosystems of brands, retailers, publishers, agencies, and technology partners. Technical capabilities abound. What the industry lacks is a shared way to evaluate when those capabilities create meaningful value.

The next chapter of DCRs centers on practical decision frameworks that help organizations determine when a data clean room creates meaningful value, when another approach is more appropriate, and what questions leaders should ask before making a significant technology investment.

Every organization will arrive at different answers based on its objectives, partnerships, data assets, and technical capabilities. But the industry would benefit from a more common way of thinking about these decisions.

Those conversations are becoming more common across the industry, reflecting a broader shift in how organizations think about technology investments.

At IAB, we’ve heard this need consistently from members navigating increasingly sophisticated data collaboration strategies. It’s one reason the Commerce Center of Excellence is exploring what a more practical, business-first approach to evaluating data clean rooms could look like.

We believe industry maturity will be defined by how effectively organizations make technology decisions. A major part of that effectiveness is knowing when to use a data clean room and when not to.
