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.

CASL will come into force in phases starting July 1, 2014 The information below should not be considered legal advice. Please consult with appropriate legal counsel before relying upon the compliance information provided below. As of December 2013 both regulators responsible for implementing Canada’s Anti-Spam Law have finalized their regulations. Industry Canada’s guidelines confirm all but one of the expected exemptions, provide needed clarifications to key requirements and delay implementation of the more controversial aspects of the law. Over the past two years we have been updating you on CASL’s developments and efforts by industry groups to address unclear or onerous aspects of its proposed regulations. With Industry Canada confirming all but one expected exemptions and providing detailed guidance in its Regulatory Impact Analysis Statement, marketers should now have an easier time preparing. Here is a summary of key points for Industry Canada’s final regulations: i. CASL will be implemented in three phases: a. The majority of CASL comes into force July 1, 2014; b. The rules that apply to computer programs will come into force January 15, 2015; and c. The private right of action takes effect on July 1, 2017. ii. Industry Canada has provided interpretive guidance on several issues under CASL, including: a. The definition of a "CEM"; b. The application of CASL to express consent obtained before CASL comes into force; c. The application of CASL to IP addresses and cookies; and d. The interaction between the unsubscribe requirement and implied consent. iii. New exceptions have been added for: a. Closed platforms, which would appear to apply to platforms such as BlackBerry Messenger and social medial networks; b. Limited-access accounts, where organizations communicate directly with recipients (e.g., online banking); c. Messages targeted at foreign persons; and d. Fundraising by charities and political parties. A surprising exclusion of the ‘Reasonable Knowledge’ exemption In its draft regulations, Industry Canada sought to exempt foreign senders in instances where the sender could not reasonably know that the message would be received in Canada, particularly when the recipient does not typically access email within Canada or through Canadian systems.[1] However, in its final rulemaking the Department chose to nix this exemption as “unnecessary,” choosing instead to exempt messages routed through Canada into a foreign state. [2] This omission may create challenges for marketers in situations where it’s not possible or practical to collect country of origin information.[3] We expect further clarification on this concern from Canadian regulators in the coming months. For detailed information please visit the Canadian Government’s informational website.

And since reverse IP geo-location records may be outdated or inaccurate, new technologies and customer self-identification processes may be needed.

As more consumers take pictures, make phone calls, read books and listen to music on smartphones and tablets, these devices replace the functions of the traditional gifts of years past. Read on to learn about this holiday’s hottest products and check out our recent Hot Holiday Products webcast to gain insight into how to capture more consumer visits during this busy season. Hot this week: Experian Marketing Services' analysis of online search trends this holiday season indicates that tech gifts are increasing in popularity this season. Smartphones and tablets rise to the top of the hot product list, as their functionality replaces that of traditional holiday gifts like cameras, books, clocks and stereos. New gaming consoles releasing this season, the Xbox One and PlayStation 4, are among the hottest products for 2013, with PlayStation currently in the lead. Tablets are also popular and the iPad is in the lead. Searches for iPad outperform those for Galaxy by a margin of more than 4:1. Hot holiday products With a scant 26 shopping days this holiday season, retailers need to identify hot products even faster than usual in order to run appropriate promotions and keep shoppers happy. Every year, Experian Marketing Services identifies the “hot products” that consumers want based on online searches driving traffic to the Hitwise® Retail 500, a grouping of the top online retail sites. This year, like last, the immediately recognizable footwear brand Ugg claims the top position on our list, as of November 9th. A new pair of cozy boots may sound nice as temperatures dip, but gadgets and electronics are what consumers are really hot for. Driving demand are two new major gaming consoles that hit the market this season. After several years without a major update, Microsoft will release the Xbox One and Sony will release the PlayStation 4. High consumer anticipation for both consoles won the PS4 and Xbox One a spot at number two and number three, respectively, on our hot products list. As of November 9th, variations on searches for PS4 were about 50 percent higher than search variations for Xbox One; however, the new PlayStation hits stores a week before the new Xbox, so this may change once both consoles have shipped. With smartphones and digital tablets performing the functions of traditional gifts of years past, such as cameras, stereos, books, watches, etc., it’s no surprise that the iPhone 5S, iPhone 5C and the new iPad Air are solid contenders on the hot product list. Likewise, the old-fashioned pedometer has been getting increasingly high-tech to the point where Fitbit, the wearable fitness tracker that links to your smartphone via Bluetooth, is the number four item on our list and searches this year are nearly three times what they were at this point in 2012. But not all of this season’s gadgets are high tech. In fact one of the hottest gadgets burning up the Web this season is about as old school as you can get: the loom, the Rainbow Loom, to be exact. We’ll cover this hot product in more detail in a bit, but it’s the number seven product on our list and one that every marketer targeting kids needs to have on their radar. Electronic spotlight With the tablet market heating up, iPads still enjoy a comfortable lead in terms of overall search. In fact, as of November 9th, search variations for iPad were more than four times higher than the nearest tablet competitor, the Samsung Galaxy. The Galaxy, however, overtook the Kindle Fire back in April of this year to become the second most searched for tablet. Tech Junkies, the segment comprised of online adults who visit technology review websites and technology content sites, are naturally more inclined to search for electronics and gadgets of all sorts, but they are even more disproportionately apt to be searching for Google and Microsoft products. For example, while Tech Junkies are 69 percent more likely than the average online adult to be searching for “iPad Air,” they are 2.7 times more likely to be searching for “Nexus 7” and 1.3 times more likely to be searching for “Galaxy Note 3,” two Android-powered tablets. Microsoft’s new tablet, the Surface 2, is also searched for by Tech Junkies at rates double that of the average online adult. Toys! Toys! Toys! When it comes to toys, it’s all about rubber band bracelets. In fact, four of the top 10 hot toy searches are tied to this trend. The Rainbow Loom and Crazy Loom (or Cra-Z-Loom, rather), are handheld looms that the young and the young-at-heart use to make rubber band bracelets (think: friendship bracelets) and other crafty creations. Since the start of the current school year, loom-related searches have taken off much to the ire of school administrators who have increasingly taken to banning the item from school premises. Video games aren’t just for grown-ups; they’re also for kids. The Skylanders SWAP Force and Disney Infinity are two sought after kid-friendly video games this year. Both allow players to bring physical action figures to digital life in video games. This is the third game in the Skylanders series and the first of its sort for Disney.
