The AdTech industry is buzzing with discussions about cookie deprecation and effective strategies to tackle it. One of the commonly suggested solutions is the utilization of clean rooms alongside responsibly sourced first-party data.
Above all else, the industry recognizes the importance of respecting consumer data and complying with all privacy laws. Additionally, the industry acknowledges the need for a change in our historical practices. This shift benefits everyone involved, as consumer data is more secure than ever. Tremendous investments have been made to ensure the utmost security of consumer information.
Clean rooms are one of the tools that enable companies to use data securely, ensuring the content that you see is as relevant as possible.
Two ways the AdTech industry is addressing cookie deprecation
The days of sending data directly to partners for usage or for using only third-party data for marketing efforts are gone. Now, the emphasis is on responsibly collecting first-party data and using clean rooms to enrich first-party data to enhance marketing efforts.
First-party data
The industry is starting to lean into first-party data gained through transparent means. This valuable information provides organizations with deeper insights into their customers, allowing for more personalized and effective interactions. By embracing the power of first-party data, either on its own or enriched via partner collaboration, you can cultivate stronger relationships, build trust, and deliver tailored experiences that resonate with your customers on a deeper level.
Clean rooms
Many data lakes and warehouses offer this service, ensuring their clients can not only store their data with them but can connect it with other partners in a secure environment and extract more information through the combined data sets versus their data on its own.
Brands and their partners recognize that they need to work together, and a clean room provides a secure environment to share their first-party data without exposing their sensitive data to their partner.
So, while we’re losing third-party cookies, brands and partners can still get value from first-party data by using a clean room to generate audience insights, segmentation strategies, personalized experiences and offers, media plans, and measurement and attribution.
Three ways data clean rooms can improve
Data clean rooms are a great way to facilitate data collaboration while ensuring sensitive data is not exposed.
Data clean rooms are not yet easy to use nor are they inexpensive. They require investment, both financially and resource allocation-wise, and you are not guaranteed to yield great match results. Let’s dive into three areas for data clean room improvement.
High cost
According to the IAB’s State of Data 2023, nearly two-thirds of data clean room users spent at least $200K on the technology in 2022. In addition, one-third of data clean room users expect the price of data clean rooms to rise in 2023. The high cost of this solution can make it inaccessible to smaller companies in the advertising space.
Resource intensive
Nearly half of the companies using data clean rooms have a team of six or more dedicated to the technology, according to the IAB’s State of Data 2023, while nearly a third of companies using data clean rooms have 11 or more employees focused on the technology. Data clean rooms are not turnkey solutions.
Inefficient matching
Even if companies are using clean rooms does not mean that they are automatically going to achieve great success. Identity fragmentation, data hygiene, and differing identifiers can suppress client match rates in clean rooms, leading to significant investment and a lackluster output.
How to get the most return on your clean room investment
The finish line for data collaboration in clean rooms is not just having a relationship with a clean room. Instead, you should incorporate an identity resolution solution in your clean room. By adding an identity solution to your clean room, you can:
- Resolve and match all your identity data, regardless of the identity data that you or your partner have, giving you a larger data foundation to analyze.
- Generate more valuable insights and information, leading to a better experience for your customers.
- Join data sets to create smarter activation and targeting strategies and produce more holistic measurement.

If you live in an early primary or caucus state, you’ve probably already had your fill of political advertising. According to The Washington Post, politicians and political groups spent more than $23 million on campaign television ads as of December 1, 2011. With record ad spending predicted for the 2012 election, the rest of the nation will soon be bombarded with television ads “approved by” politicians from the left, right and the center of the political spectrum. Candidates and those groups that support them need to know where to allocate their ad dollars to either connect with their base or reach swing voters. Experian Simmons analyzed the viewing audiences of over 600 broadcast, cable and syndicated TV programs that were measured in our most recent National Consumer Study in order to pinpoint opportunities for politicians to reach partisans and middle of the road voters. This analysis has already gathered the attention of major media outlets, including Entertainment Weekly, The Washington Post, AOL, Huffington Post and more. Below are the entertainment and news programs that score the highest concentration of liberal Democrats among their viewers, Conservative Republicans and Middle-of-the-Road Voters registered with any party. Be sure to check out our free 2011 PoliticalPersonas report in which Experian Simmons delivers the mindset of the American voter, including attitudes, brand preferences and their penchant for social media. You can also check out a similar analysis of TV preferences of political partisans that we conducted last year here and here.

Social media continues to be one of the fastest growing industries online. Between September 2010 and September 2011 visits to Social Networks and Forums have increased by nearly 11% and, if you saw my Internet clock blog last month, social media accounts for nearly a quarter of all time spent online. But when are people engaging with social media the most? We took a look at the UK Internet visits to the Social Networks and Forums category each month between 2009 and 2011. We then averaged those visits across the months to see the seasonal trends with social media. What this shows is that social media usage is at its lowest at the beginning of the year and climbs throughout the course of the year towards a peak in December. Over the last three years December has always seen the peak of online visits and in fact last Christmas Day Facebook overtook Google for the first time ever in terms of UK Internet visits. We know that Christmas is a very social time and a time for sharing messages with loved ones, friends and family, so the increased visits to social networks during December is to be expected. More generally, what this graph shows is that social media observes two seasonal trends. The first is an early summer peak in visits in June, before a decline in visits in July and August. This seasonal dip in July and August can be explained by summer holidays where people are more likely to go abroad and therefore less likely to be using social networks. The second seasonal trend is a recovery in visits in September and October before a yearly peak at Christmas. With students starting university terms, kids going back to school, and the working population returning from holiday this would account for the increased interaction in September and October before the Christmas surge. In particular what we’ve seen in September data is a resurgence in market share of visits to Facebook, which bounced back after the summer dip to account for nearly 52% of all visits to a social network. The message here for brands who want to capitalise on social media traffic is to start implementing their social strategy now rather than waiting for Christmas. As October is the second busiest month of the year for social media visits we are expecting over 800 million hours to be spent on social networks this month, which represents a huge opportunity to engage with new and existing customers online.
