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.

As part of our ongoing series which focuses on consumer and marketing trends around major holidays throughout the year, we’ve just released the Father’s Day Hot Sheet. Father’s Day gift-related searches Now that Mother’s Day has come and gone, consumers will be shifting their focus to dad. According to Experian Marketing Services’ Hitwise® online intelligence tool, searches for “Father’s Day” typically start to pop up on Mother’s Day. And searches for “Father’s Day gifts” tend to focus on affordable gift ideas that are personalized, unique and often handmade. In fact, two of the top variations of Father’s Day gift-related searches from 2014 were for “DIY” and “homemade” gifts. While many shoppers wanted the “best” gift for dad, others simply wanted something “cheap” or “last minute.” Finding a gift that dad will appreciate means looking for something that is personalized to him. As such, searches for Father’s Day gifts often contain additional information about the dad or, in many cases, grandpa. Examples commonly used in 2014 were “Christian dad,” “new dads,” “outdoorsy dads” as well dads who are wine or BBQ lovers. While many gift searches include information about the intended recipient, others mention details about the gift-giver or their relationship to the father. Among last year’s variations that included such details, nearly a third focused on gifts that were intended to be given by a “daughter.” Genderless references, such as “kids” or “children” were almost as common. Interestingly, fewer than ten percent were for gifts to be given by a “son.” About a fifth of searches included details about the age of the gift-giver (e.g.: “baby,” “toddler” or “first grader”), while others specified that the gift was to be given by the dad’s wife or girlfriend. Go, go, gadget dad! Gadgets and gizmos are always popular gifts for the techie dad. In fact, during the week immediately preceding Father’s Day last year, visits to Electronics and Appliance websites were up a relative eight percent from two weeks prior. Visits subsequently tapered off the following week. An analysis of search terms driving traffic to the Hitwise Electronics and Appliance industry the week ending June 14 versus May 13, 2014 also sheds some light on the specific items that Father’s Day gift-givers were likely to have been seeking out. Two GPS systems (“Magellan GPS” and “Tom Tom”) were among the top terms that grew search share in the weeks leading into Father’s Day last year. Likewise, “GoPro” appeared in two separate fast growing search terms. Gadgets like these and others listed in the adjacent table may be big gifts for the gadget-loving dad again this year. Gone fishin’ Fishing is a timeless family pastime enjoyed by millions of Americans. According to Experian Marketing Services’ Simmons® National Consumer Study, 28 percent of dads and 26 percent of kids ages six to 17 went fishing last year. As such, it’s no surprise that online searches related to fishing spike over Father’s Day weekend. On the Saturday before Father’s Day in 2014, searches including “fishing” were a relative 28 percent higher than they were the Saturday prior and 64 percent higher than they were the following Saturday. To better understand what kids and dads were seeking out for their fishing plans, Experian Marketing Services conducted an analysis comparing variations of “fishing” searches immediately before Father’s Day last year to those performed two weeks prior. It turns out the word “techniques” was almost 8.6 times more likely to appear in fishing-related searches just before Father’s Day than it was two weeks earlier and “tips” was four times more likely to be used. Likewise, “licenses” was used 2.3 times more frequently, which along with the higher use of “techniques” and “tips” is evidence that many would-be fishermen and women are occasional participants at best. The fact that “charter” and “cabins” were used at higher rates however suggests that other children and/or dads had something in mind beyond a lazy (and likely more affordable) afternoon at the local fishing hole. Gift items, too, like “reels,” “gear” and “tackle” were among those most disproportionately used in searches heading into Father’s Day.

Welcome! Who doesn’t like a warm welcome? Whether your customer is walking into your store or just signed up on your website to receive communications from you, she expects a warm reception. It’s important to make that first impression count. A welcome series helps the conversation open up between the customer and your brand. It sets expectations on the types and cadence of content the customer will receive. Welcome emails also garner 86 percent higher open rates than regular promotional mailings – not too shabby! In a recent webinar, Saks Fifth Avenue shared that they are constantly testing new and current programs to optimize the customer experience. As a result, they discovered that switching from batch-sending welcome emails to sending welcome messages in real time increased open, click and redemption rates significantly. Here’s an example of their welcome series: Saks’ results are consistent with Experian Marketing Services’ welcome email findings which indicate that emails triggered in real time receive up to 10 times the transaction rates and revenue per email vs. those that are batched. A welcome series has also been shown to increase retention by educating customers on new ways to use products and services they’ve purchased from your brand. These emails also can remind customers of the benefits they’ll reap from enrolling in your loyalty programs or credit card. … and welcome back Even if a customer has been welcomed and has interacted with your programs, a day may come when the customer goes silent. Reactivation campaigns are an effective way to get them to re-engage. Naturally, it’s important to target your dormant customers in a variety of channels so you can reach them more effectively. Maybe you’re wondering why I jumped from the warmth of a welcome series right into reality of needing a reactivation campaign. The reason? Marketers need to understand where a customer is in their lifecycle and come full circle with customers if they have parted ways. Marketers can pique the interest of a returning customer by telling them what’s new and reintroducing them to their brand. Carnival® Cruise Lines, for example, sends a welcome-back email that features the newest social networks, offers and deals its customers can take advantage of immediately. At the end of the day, customers expect to receive relevant and engaging messages throughout their entire relationship with a brand. Customer life cycle programs deliver just that.

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?
