The concept of the “hedged garden” is gaining traction in the AdTech space as a promising new approach. It offers a more controlled and protected environment for advertisers, reshaping how digital advertising operates. But what exactly is a hedged garden, and could it be the solution we’ve been looking for? Let’s dive into the details and explore its implications.
Walled gardens vs. the open web
Walled gardens continue to disrupt the advertising industry to stay relevant. Google, Meta (Facebook), and Amazon, the largest walled gardens, offer consumer privacy and rich first-party data to advertisers. But, time spent within these platforms, Google and Meta specifically, continues to decrease.
Open web: Pros and cons
On the other hand, the open web allows for more transparency, scale, and constant diversification. Yet, this has not led to increased spending. As a result, the open web continues to lag behind walled gardens. With a heavy reliance on third-party data and growing concerns over signal loss, the open web faces significant challenges. Under these circumstances, advertisers turn to easy activation channels like walled gardens, even as they become less effective to marketers.
Consumers are increasingly focused on privacy, pushing the industry toward alternatives to third-party cookies. As Google rethinks its cookie deprecation plans, channels like connected TV (CTV) and mobile apps, which don’t rely on cookies, are gaining traction.
“A significant portion of web traffic does not support cookies today — and that number will grow as Google rolls out [its] new solution. This means that the industry shouldn’t slow down investments in cookieless solutions, including alternative IDs, first-party data and data-driven contextual targeting.”

This shift emphasizes first-party data and user choice as a potential solution that balances privacy with effective advertising sources.
Enter the hedged garden
So, what is a hedged garden? The “hedged garden” is a new industry concept where a network of publishers works together to activate first-party data sets in a privacy-compliant way across many partners at scale. These publishers run their businesses with large amounts of first-party consumer data. But they are not big enough on their own.
What does a hedged garden look like? Hedges are more permeable and not as tall as walls. This idea is key to the success of the hedged garden.
Data protection and privacy regulations
As hedged gardens grow, staying compliant with privacy laws like the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA) is vital. These rules focus on protecting user data by requiring clear consent and transparency. Hedged gardens help publishers share first-party data in a safe, privacy-compliant way.
By working together, they ensure data is used responsibly, aligning with strict privacy regulations. This not only keeps marketers compliant but also builds trust with consumers at a time when data protection is more important than ever.
Opportunities for marketers in hedged gardens
Hedged gardens offer unique opportunities for marketers to enhance their strategies. Unlike walled gardens, hedged gardens offer the ability to work with a wider array of data sources and provide more diverse insights into audience behavior. This flexibility lets marketers develop more tailored, cross-platform campaigns that reach users in different ways.
Additionally, hedge gardens encourage collaboration with multiple partners, allowing for new partnerships and innovative strategies. With data from several sources, marketers can create more precise and privacy-compliant targeting methods to deliver better results. With the right approach, hedged gardens give marketers the freedom to break away from restrictive ecosystems and drive creative and impactful growth.
How Experian navigates through hedged gardens
As our ecosystem moves toward a hedged garden solution, how do we get involved? We are already a key ingredient for this type of solution within the TV landscape. Below, we walk through how we partner with one of our current TV media clients.
Organize our client’s data and provide a Living Unit ID (LUID)
First, we work with our client to clean and enhance their data, matching individual personal identifiable information (PII), such as an email address, to a household through a LUID. Our Digital Graph, which includes hashed emails (HEMs), cookies, mobile ad IDs (MAIDs), IPs, universal IDs, and CTV IDs, is rebuilt weekly to create accurate, refreshed connections. This consistent linkage creates precise targeting and measurement over time.
Our interconnected Offline and Digital Graphs organize identity into households and devices, enriched with marketing data for deeper insights and better addressability. With partnerships across major platforms, we improve match rates, helping you activate audiences seamlessly for optimal reach and measurement.
Enrich data through Experian Marketing Data
Next, our TV media client licenses our Marketing Attributes. This data is the most comprehensive resource for both traditional and digital marketing campaigns. With its multi-channel availability and addressable capabilities, our Marketing Attributes allow our clients to develop insights and build audiences based on a wide range of attributes within their segment set, ensuring they reach relevant audiences across all channels.
Activate audiences across the ecosystem
Finally, we help our client execute their audiences across the full digital and TV ecosystem. We enable the connection that allows these audiences to be activated by matching partner LUIDs (example: LUID123 = LUIDABC). By using client-specific LUIDs to match up data in a privacy-first manner, we can continue to build strong partnerships within the fast-growing ecosystem.
Are hedged gardens the future of advertising?
Have we found the perfect bridge between walled gardens and the open web? We’re hedging our bets. Our vote is yes, but only time will tell.
The future of advertising is shifting, and hedged gardens appear to be a promising model that balances the scale of walled gardens with the flexibility of the open web. We’re using what we learned from the TV industry to support other hedged garden verticals (retail media networks, audio, and gaming).
Now that we know what a hedged garden is, we should consider what the future holds for both walled and hedged gardens.
What’s next for walled gardens
- Increased privacy regulations: Walled gardens will face stricter regulations on data use, pushing them to adapt for compliance and trust.
- Reduced market dominance: As advertisers want more control, reliance on walled gardens could decline, shifting focus to hedged gardens.
- Diversified ad spend: Brands may spread their budgets across multiple platforms instead of being locked into walled gardens.
The future of hedged gardens
- Greater industry collaboration: Expect more publishers and platforms to join forces in hedged gardens for better data activation.
- Expansion into new channels: Hedged gardens will expand into emerging channels like gaming and connected devices.
- Improved data integration: Privacy-first data sharing in hedged gardens will lead to smoother, more secure ad targeting.
Data collaboration in a post-cookie world
As signal loss becomes a growing concern, the need for secure, privacy-first data collaboration will rise. Hedged gardens offer a pathway forward, allowing advertisers to activate first-party data across multiple partners while complying with data regulations.
This is where Experian Collaboration shines. By enabling data sharing without exposing raw consumer data, clients and partners can collaborate at Experian in their own environment or in clean rooms. Each of these environments allows partners to exchange data and gain insights without compromising privacy.

In a previous blog entry, Ordering sushi and a lesson in embracing the contextual marketing mindset, I showcased a fictitious scenario that required complex data point integration to pull off. These kinds of programs can seem overwhelming given the three barriers that many organizations face when embarking on their contextual marketing journey: Marketing sophistication A brand’s own conventional mindset and the programs that support it Actionable data Lack of clean and accurate data that prohibits real-time “on the fly” interactions Technology Disparate systems that are unable to link information across repositories, channels and interactions; inability to automate interactions in real-time Regardless of the barriers, there are ways you can show customers you’re listening and provide contextual messages without “boiling the ocean.” Take, for example, the recent viral blue/black vs white/gold dress debate. As the conversation spread throughout Facebook and Twitter, brands like Dunkin’ Donuts and Tide tweeted these contextual messages: The tweets did not go unnoticed as thousands of followers retweeted, commented and favorited these messages. The contextual elements used in these messages — channel preference and breaking/relevant news — are easily accessible to any brand. While the brands had to act swiftly, executing these messages circumvented the three barriers listed above. On the flip side, addressing the barriers can allow a brand to build more sophisticated, targeted contextual messages, as shown in the below example. Here, Experian Marketing Services and technology partner Movable Ink helped Finish Line deliver this sale announcement that adjusts based on the date and time the customer opens the email. The message remains relevant via a countdown clock during the run of the sale, a “warning” when it’s about to end and an alternative message after the sale ends — all of which ensures that the message is relevant regardless of when it’s opened by its intended recipient. And combining more contextual data points, such as location and stock, Finish Line includes the countdown, a local map to the customer’s nearest location and up-to-the-minute inventory of available sizes. Contextual marketing enables modern enterprises to engage in customer-centric conversations that — like any meaningful relationship — deepen across time and future points of engagement. This is particularly true in an era when consumers are overwhelmed by untargeted and disruptive marketing messages. By contrast, contextual marketing is designed to seamlessly and usefully merge into the customer’s daily activity. Want to know more and how to get started?

With online video viewing at an all-time high and television networks and system providers increasingly making video content available to those who don’t pay for television, many are wondering if we’re on the cusp of a massive spike in cord-cutting numbers. In our recent Cross-Device Video Analysis, Experian Marketing Services found that that 7.3 percent of all U.S. homes are cord-cutters, meaning they have high-speed Internet but don’t pay for TV. And the pace is increasing. In the last year alone, one million more homes joined the cord-cutter ranks bringing the total to 8.6 million households. It should come as little surprise that cord-cutting is on the rise. As we reported in our video viewing habits post, 57 percent of all American adults and 75 percent of Millennials now watch some sort of digital video during a typical week with the smartphone being the most commonly used device for watching video either streamed or downloaded from the Internet. Consumers thinking about cutting the cord will find an industry increasingly working to remove barriers that typically stand between cord-cutters and programming from their favorite networks — in exchange for a small fee. For instance, CBS recently announced the launch of CBS All Access, a digital subscription service that provides live and on demand viewing of CBS programming. And Dish Network launched Sling TV, an over-the-top pay service that allows cord-cutters to stream live and recorded programming from networks like ESPN, Univision, CNN, HGTV and more. With HBO announcing an April launch of their digital-only streaming service, HBO Now, March may be the last month that many pay for cable or satellite. If the cord-cutting ranks are, in fact, about to swell, a common question is: by how much? Experian Marketing Services estimates that there are currently 13.8 million Americans — representing 5.6 million homes — who are prime to cut the cord. Many of those individuals already have one foot out the door, if you will, given that they are more likely than average to say that they watch less television today because of the Internet. They are also more likely to watch HBO and be fans of at least one major professional sport making them good targets for Sling TV and HBO Now. Given that many cord-cutters already pay for Netflix and/or Hulu Plus, the net savings to those on the fence may be smaller than they think once they add up the costs they’ll assume from piecing together, à la carte, the various subscriptions and downloads required to keep watching their favorite programs. Whether or not we’re on the cusp of a major spike in cord-cutting, the fact is that consumers are increasingly getting their video content from digital sources and marketers need to understand where, how, when and what consumers are watching to ensure that their video campaigns are optimized for today’s digital consumer.

Advertising Age recently released their annual Marketing Fact Pack, featuring data from Experian Marketing Services that looks at habits of digital consumers. This post highlights some of these findings. In the 2015 AdAge Marketing Fact Pack, we featured stats on key marketing and consumer trends impacting the advertising industry. Highlights include the lifestyle of the digitally connected consumer, including the habits of smartphone and television users, household and personal use of smart devices and the choice between becoming a cord-cutter and staying connected. An estimated 7.3 percent of U.S. households (8.6 million homes) today are considered “cord-cutters,” meaning they have high speed Internet but no cable or satellite television service. That number is up from 4.5 percent of households (5.1 million homes) in 2010, a comparative increase of 60 percent. Despite the growing number of consumers who use digital devices to watch video (as opposed to viewing on a television), it has not been enough to overwhelmingly convince all households to cut the cord. Instead, it seems as if the ability to stream or download video directly to the television is what ultimately seals the deal. As streaming devices like Roku, Apple TV, Amazon Fire TV and Google Chromecast become more common and as televisions themselves are increasingly connected to the Internet directly, we can only expect the number of cord-cutters to grow.
