Data Clean Rooms: What Marketers Need to Know

Data Clean Rooms and CDP: What Marketers Need to Know

The deprecation of third-party cookies, increased data privacy regulations and compliance requirements have challenged marketers to shift their marketing and advertising programs towards a first-party data strategy. Now, marketers are exploring new ways to optimize ad spend, create better loyalty programs, and provide the best digital experiences by building direct relationships with customers. 

Enter the rebirth of data clean rooms. It’s not exactly a new tool for data management, but it helps resolve some of the biggest data-oriented challenges marketers face today. According to Gartner, 80 percent of advertisers with media budgets of $1 billion or more will be using data clean rooms by 2023. 

What is a Data Clean Room?

A data clean room is a secure and anonymous private data exchange. It’s a database where a company matches its first-party data with aggregated data from a second-or-third-party data source, like a publisher or a trusted partner. Once the data sources are matched up, one or both parties can analyze the combined data to be leveraged for various applications.

Here’s how it works:

  • First-party data is combined with aggregated data from a third-party source, like a publisher, without sharing personally identifiable information (PII) or raw data. There is no way for either party to reverse the data to get the PII.
  • Each data provider sets the permissions for what and how its data is analyzed. There are strict privacy controls in a data clean room, and each party specifies what data the other party can access.
  • This data typically lives in the data clean room environment. Only aggregate data is queried.

In most cases, all data is brought into a central location, but there are some examples where distributed data clean rooms (such as from Snowflake) keep the data in its original location, and its owner allows controlled analytics to the other party.

Types of Data Clean Rooms

Data clean rooms help organizations process and analyze data from different partners in a secure and compliant way. The best data clean room for your organization will depend on your goals.

Walled Gardens

The most prominent examples of data clean rooms today are walled garden data clean rooms that come from big ad media publishers, like Google Ads Data Hub and Amazon Marketing Cloud

When you work with a data clean room from one of these walled gardens, you analyze the performance of your ads from the individual publisher’s platform –  they do not provide a cross-platform perspective. One drawback of these data clean rooms is you cannot analyze performance across publishers. There may also be restrictions or limitations on how you can use the data.

AdTech Vendors

AdTech vendors or agencies also provide data clean rooms. However, in certain cases, there may be no way to know if the data clean room’s attribution model methodology is valid or accurate. If you choose to work with someone else’s data clean room, you need to ensure it provides the security necessary to house your first-party data and that your data is appropriately pseudonymized to safeguard the privacy of customer information.

Private Data Clean Rooms

Today, many companies and independent vendors are building their own private data clean rooms. There, they can work with multiple partner datasets to create an omnichannel view of their customer data to analyze for various purposes, like optimizing advertising spend or executing personalized marketing campaigns.

Why Are Data Clean Rooms Important?

Consumers are now more aware of how brands use their personal information. Privacy laws also continue to come into place to protect consumer privacy. Regulations like the European Union’s General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) are the two most well-known privacy laws, but they are just the start to a broader data regulation environment.

Publishers like Google and Apple have also restricted third-party cookies and have implemented tools that allow consumers to control how their personal data is shared. 

Access to first-party data that comes from a consumer’s direct interaction with a brand helps marketers understand a lot about their customers, but it doesn’t always tell the entire story. Second-and-third party data from partners, publishers, and ad networks help fill in the missing pieces.

Data clean rooms provide access to third-party data that privacy laws and the end of cookies are taking away. 

Data clean rooms give this access in a secure, compliant environment, allowing marketers to:

  • Understand how customers are interacting with brands
  • Find wasted ad spend or avoid duplicated effort across channels
  • Identify lookalike audiences
  • Build new segments for targeting
  • Determine customer lifetime value (CLTV).

Depending on the type of data clean room, marketers may be also able to build custom audiences that can be sent directly to an ad platform, whether that’s a publisher, ad network, a demand-side platform (DSP), or a customer data platform.

How To Use A Data Clean Room to Improve Data Strategy

There are many use cases for data clean rooms, but the most well-known is between a publisher and an advertiser.

We’ve already talked about the walled gardens of Google and Amazon, which publishers own their own data clean rooms. Advertisers bring in their first-party data and then analyze the combined data to understand ad performance. .

If an advertiser works with multiple publishers, they have to perform their analysis separately for each publisher and then manually bring that data together to give them a more holistic view of their ad spend. The same is true if an advertiser wanted to work with a data clean room from an AdTech vendor.

However, there are data clean rooms run by agencies that bring in third-party data from multiple ad networks, publishers, and demand-side platforms, giving advertisers a complete picture of ad spend (though this still would not include data from the walled garden publishers).

Retailers and Consumer Packaged Goods (CPGs)

Another use case for data clean rooms is for CPG companies. Since CPG companies do not sell their products to consumers directly, they have limited transaction data. They do, however, have first-party data from direct-to-consumer interactions, marketing, advertising, and loyalty programs.

The retailers that sell CPG products have additional transaction data from their own marketplaces or platforms. So, if the two parties combined their data in a data clean room, CPG companies could better understand how their marketing campaigns were driving purchases from the retailer. They could also analyze the combined data to improve targeting and segmentation of their campaigns and offers to specific high-performing segments through a retailer’s media network.

Strategic Partnerships

While airlines, hotels, and car rental services do not provide the same services, these services are complementary and often are purchased together. If these parties were to combine their data, they could better understand what their target markets want. By analyzing the shared dataset, they may find opportunities to co-market or deliver loyalty programs that provide more value for both the customers and involved partners.

Working Together: Data Clean Rooms and CDPs

A customer data platform (CDP) is at the heart of your first-party data strategy. It’s where you bring together first, second and third-party customer data to build a single customer view that’s required to create personalized, relevant experiences at scale. 

A data clean room is an extension of a first-party data strategy. A brand can connect its CDP to a data clean room to allow first-party data to be anonymized and analyzed alongside third-party sources. It can also receive data from the data clean room in the form of segments or targeted audiences it can then share with connected marketing platforms for activation.

A CDP does not provide the same environment as a data clean room. But it does give data providers and organizations centralized control of their data and its use. Together, a data clean room and a CDP allows organizations to manage, process and analyze data in way that’s safe, efficient and compliant. Staff Staff
