The Data Clean Room: What It is and What Advertisers Need to Know

Data Clean Room - What It is and What Advertisers Need to Know

If you’ve been paying attention to the unfolding of data privacy regulations and technology changes, you’ve likely encountered the term “data clean room” (DCR) at least once. The growing buzz around this concept tells you just how important the new solution is in today’s digital landscape.

And how can you tell that a new technology category is getting momentum and attention? The answer is simple: When it earns its very own acronym, of course! So welcome to the world of data clean rooms, where privacy, collaboration and innovation converge.

Explaining the Hype Around Data Clean Rooms

Let’s take a quick step back to better understand how we arrived at data clean rooms. Data clean rooms have quickly become a focal point in discussions about data privacy and collaboration. But what exactly is driving this surge in interest? The answer lies in the evolving dynamics of data usage, privacy concerns and of course — third-party cookies. As brands grapple with a confusing and quickly-changing customer data landscape, they need ways to make the most of their data — with data clean rooms offering a compelling solution.

Third-Party Cookies Were Going Away — But Not Anymore

Let’s take a moment to revisit the journey that brought us to the era of data clean rooms. Over the past few years, we have witnessed a shift in how customer data is handled, largely driven by growing customer data privacy concerns. This shift has triggered a cascade of events that reshaped the digital landscape:

  • In 2016, Europe set a precedent by adopting its first privacy regulation law, General Data Protection Regulation (GDPR), marking the beginning of a new era in customer data privacy.
  • Following suit, Apple introduced limitations on third-party cookies in 2017 and eventually phased out third-party cookies entirely from its Safari browser by 2018.
  • The United States wasn’t far behind, with California enacting the California Consumer Privacy Act (CCPA) in 2018 and reising its restrictions around customer data privacy with the California Privacy Rights Act (CPRA) in 2020.

We could keep going, but the event that really created the highest reaction on the market is Google’s announcement in 2020 to also remove access to third-party cookies from Chrome. Third-party cookies are the main currency exchange in the advertising industry. Despite its flaws, this is cheap and provides scale. And while the recent news that third-party cookies aren’t going away has given some advertisers relief, the truth is that solutions built on first-party data will continue to gain traction.

So, what’s next for advertisers, agencies, publishers, and tech vendors who have relied on third-party cookies for so long?

Join the (Second) Party (Data)

The industry agrees: the best alternative for brands is to focus on their first-party data strategy. Provide value to the consumer in exchange for their (consented) data.

Some industries — such as retailers (thanks to customer transactions) and premium media (thanks to their early subscription and paywall strategy) — are leading the pack in getting access to first-party data. But this is not the case for everybody: most CPG and automotive brands don’t have the same customer data maturity or opportunity.

Across the board, first-party data won’t provide the same scale known with third-party data. So what is the next best alternative? Second-party data.

Second-party data refers to first-party data collected by another brand. It’s incredibly valuable because it represents someone else’s first-party data, which is typically of high quality and relevance. However, there are significant privacy concerns associated with sharing such data, and brands are understandably reluctant to part with their most valuable assets.

So, how can brands safely access and utilize second-party data?

The Inception of Data Clean Room Technology

In 2017, Google led another major industry change: it “quietly” launched a new product called Ads Data Hub. At the time, this beta product was presented as a “next generation insights and reporting” tool.

It was the inception of data clean room technology, but the term was not coined yet. Google announced that it would stop sharing log-level data with advertisers. At least the IDs identifying an individual would no longer be provided.

The challenge? Without access to this data, advertisers would not be able run advanced analytics and reporting on their advertising campaigns on Google properties such as YouTube.

The solution? Ads Data Hub would provide access to the raw data for insights and reporting — without allowing advertisers to export this information in their own tools. Walled Gardens were born, and they don’t give away the valuable collected data anymore, in the name of privacy.

What is a Data Clean Room?

So what is a data clean room (DCR)? In a nutshell, it’s a potluck — but not the traditional one you are familiar with.

First of all, to access the room in which you will taste other people’s food, you need to show your credentials. The entrance is safely guarded 24/7. Then, the room itself is dark so you can’t actually see anybody’s food. And you can’t leave the room with the food either: it’s meant to be tasted “on-site.”

In essence, a data clean room is a secure environment for data collaboration. Let’s dive deeper into the key characteristics of data clean rooms:

  • Secure: The data clean room environment hosting sensitive data sets is sealed, weatherproof, and privacy-compliant. It means that data stored is encrypted and only authorized users can access it. Sensitive data stored in a data clean room should not be able to leave that clean room.
  • Data Collaboration: The primary purpose of a data clean room is to facilitate data collaboration between two or more parties. It allows organizations to combine their data sets to gain insights and drive better decision-making.
  • Privacy-Compliant: A data clean room does not store personally identifiable information (PII) and ensures that individual consumers cannot be identified. This makes it a powerful tool for privacy-conscious data collaboration.

Is a Customer Data Platform a Data Clean Room Too?

While a couple of customer data platform (CDP) vendors announced clean room technology or capabilities in 2021, the purpose and technical capabilities required are different for a CDP and a data clean room.

A CDP’s primary focus is on collecting, organizing, and activating first-party data sets to deliver personalized customer experiences. It’s designed to help business teams take action on customer data across the entire customer lifecycle.

On the other hand, a data clean room is specifically designed to enable collaboration between two parties using each other’s first-party data. It’s a secure environment where data can be combined, analyzed, and used for insights without compromising privacy.

While CDPs and data clean rooms serve different purposes, they can complement each other within an organization’s tech stack. Together, they offer a powerful combination of data management, collaboration, and activation capabilities.

As the digital landscape continues to evolve, brands must focus on managing data governance, controlling costs, and optimizing performance to drive growth through exceptional customer experiences (CX). In this ever-changing environment, data clean rooms offer a future-proof solution for safe and effective data collaboration.

Safe and Effective Data Collaboration

Not long after Google, Meta (Facebook at the time) deployed its own clean room technology. These first clean rooms were really built for the biggest advertisers on Google and Facebook properties, the cost made them out of reach for smaller brands.

The data collaboration process itself was run by data engineers and analysts using SQL queries. No marketer would be able to access an interface and discover the insights themselves at the time.

Amazon was even quieter. They were suspected of developing a similar technology, but no public documentation or information was available.

The initial use cases for data clean rooms were focused on improving attribution and measurement for ad buyers. As we saw with Google suppressing the option to export raw logs with IDs, an alternative was required to understand the performance of advertising campaigns.

With the announcement of third-party cookie deprecation, we are seeing the emergence of new use cases for DCRs. They are no longer limited to attribution and measurement post-campaign execution.

This technology can help access insights from audiences, match data between advertisers and other parties including media owners, data owners, and identity providers. Improved targeting is enabled by allowing an advertiser to activate matched data set directly to an addressable channel — when the data clean room provides an integration with that channel — or export owned data back to another system of the brand.

Who Are Data Clean Rooms for?

To start any collaboration, you need at least two parties. Typically, a DCR will be used for a collaboration Brand ↔ Brand, Brand ↔ Publisher or Business Unit ↔ Business Unit.

Organizations are building and growing their partnership ecosystem and we are seeing synergies between industries and/or markets. Some of these partnerships could be directly visible to the end customer, such as what we’ve seen with Delta and Lyft and Chipotle and e.l.f.

More generally, we expect advertisers to create more direct partnerships with publishers and CPG brands to collaborate with retailers selling their products.

How Do Data Clean Rooms Work?

Once two parties have found an agreement, legal and technology to use for the collaboration, the process will happen in three steps:

  1. Import Data in the Clean Room: A brand makes its first-party data available to the clean room from its systems. A common scenario is to leverage a CDP integrated with the clean room to share these first-party datasets.
  2. Matching: In order to match data sets between the two parties, a common identifier is required. Identifiers accepted by DCR can vary, but you will find options such as PII (email address), hashed PII, or the cookieless IDs available on the market such as UID2, the Fabrick ID from Neustar or the Merkury ID from Merkle. No matter which option is chosen, data will be de-identified using various techniques developed by the DCR, ensuring that this process cannot be reverted. The result — and not the raw data ingested — is used to match data sets.
  3. Data Collaboration: Now the data can be used for planned activities, from audience segmentation and insights to activation and measurement. A data clean room often offers direct integration with paid media channels, but the activation can be orchestrated back into the system of choice, such as a CDP, to build personalized customer experiences.

Key Benefits of Data Clean Rooms for Businesses

Data clean rooms offer numerous benefits for businesses across various industries, making them an essential component of modern data strategies. Here are some key advantages:

  • Enhanced Data Security: With stringent privacy controls, data clean rooms ensure that sensitive information is protected, reducing the risk of data breaches and compliance issues.
  • Regulatory Compliance: As privacy regulations like GDPR and CCPA become more stringent, data clean rooms provide a compliant environment for data collaboration, helping businesses avoid costly fines.
  • Improved Collaboration: By enabling secure data sharing between partners, data clean rooms facilitate better collaboration, leading to more effective marketing strategies and customer insights.
  • Advanced Analytics and Insights: Data clean rooms allow businesses to perform sophisticated data analyses without compromising privacy, driving better decision-making and more personalized customer experiences.

Start Data Collaboration Now With Data Clean Rooms

The adoption of data clean rooms within an organization is still generating a lot of debate. The cost of entry is particularly high, especially during a time of uncertainty. And we are not talking about the technology cost alone, as the first barrier will be a legal and process one.

How do you start with creating these relations directly with brands and publishers? How do you ensure that privacy laws are respected? That consumer consent is collected and respected? Once these matters are clarified, which data clean room(s) should my organization even adopt?

All these questions and more will have to be answered. But as we shared earlier, first-party data in itself won’t provide the scale necessary moving forward. So organizations need to explore partnerships and data collaboration.

“As third-party cookies and other unstable identifiers become obsolete, businesses will need a new way to reach their customers while protecting and prioritizing their privacy. 2022 was very much the year of clean room curiosity, but 2023 shaped up to be the year of clean room construction, with innovative organizations now building new first-party solutions on top of them,” said Valerie Mercurio, VP, Business Development at InfoSum.

“2022 was very much the year of clean room curiosity, but 2023 is already shaping up to be the year of clean room construction,” said Valerie Mercurio, VP, Business Development at InfoSum.

Testing data clean rooms early is the best option to be prepared for the future, and as Mercurio is adding, “data clean rooms are no longer a trend, companies have realized that they are a must-have in the first-party era. As a foundational element of an organization’s tech stack, they are a significant opportunity to further differentiate from competitors.”

“Today, data clean rooms are enabling advertisers to collaborate quickly, easily and effectively with their media and data partners. We’ve seen incredible results among our clients and partners — reducing costs, improving return on ad spend and increasing conversions upwards of 20%,” Mercurio noted.
