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.

By now you’ve all seen the headlines about the burgeoning success of eCommerce compared to the relatively drastic decline in transactions for brick-and-mortar stores during the holiday season. ComScore data showed desktop online sales in the last two months of 2016 rose 12%, and are expected to rise to 16-19% once the mobile commerce numbers are tallied. This steady downward trend for brick-and-mortars has been caused by a variety of factors. Amazon has carved out a desire for free, fast shipping and one-stop shopping. The rise of “fast-fashion” pushes consumers to buy mass-produced and cheap clothing that is easiest to replicate online, and the wide-spread usability of eCommerce and mCommerce sites make the experience of online shopping hassle free. Many organizations have relied on the in-store experience to garner loyalty, so now the question is how to achieve that same experience in the digital realm as foot traffic to stores falls to all-time lows. The answer lies in understanding your users and tailoring content, not just products, within your communications. Experian Cross-Channel Marketing’s studies have shown that by incorporating editorial content into email, overall audience engagement can rise by up to 28% over audiences that don't receive content-driven messages. That’s an increase of over 20% in opens, clicks, and transaction rates! Now to be clear, this is content that is NOT focused on the sale, but rather, how the products, services, or organization can better the user’s life. Let’s dive into this a bit more deeply by talking about the types of content you can weave into your communication strategy: Product Tutorials This is the easiest to execute for those wanting to digress from the discount epidemic plaguing us all. Instead of flaunting a low price, highlight product versatility, create a video showing ease of use or wow the audience by demonstrating transformative effects with before and after photos. Bring the experience to them virtually rather than relying on a showroom to demonstrate the value. The more you draw your users into this experience, the more likely they are to remember your brand. Social Highlights + Celebrity Bloggers Many organizations spend a great amount of time and energy developing a solid social strategy, but fail to bridge the gap between social, email, the website, and even in-store experience. Pull favorite items, the highest rated products, or user-generated content into email to add a personal, more relevant touch to your brand. Also consider bringing any celebrity or blogger content to the forefront of your eNewsletters to achieve the same goal. After Your Purchase Experian has found that Welcome Emails containing a “Thank You” message for those that purchased produced 20x the revenue per email than promotional welcomes. These users are primed to purchase again as they have already shown interest in your organization, so why not incentivize another transaction immediately when appropriate? However, don't forget that the user journey doesn’t stop at the transaction. A huge part of customer satisfaction comes after the credit card has been swiped. Send communications to ensure the user knows how to care for their product, prepare for their service, or simply send a survey after their journey is complete. Including additional options to purchase should be secondary to making sure you get THIS transaction right. How It’s Made Is your product made in America, handcrafted, or come with special care that makes your brand stand out? Are your services or designers top rated for good reason? Give your customers a behind the scenes look to entice them and peak their interest in your brand. A Bigger Purpose Does your brand have a mission that will resonate in the hearts of your consumers? Is there a give-back program you think your audience will care about? If so, bring that bigger purpose to the spotlight and give your consumers a reason to be a part of your community. As your content strategy becomes more advanced, consider profiling your audience to understand their messaging preferences, and then test your content across these cohorts. Not all content will resonate with all customers, but finding the right content marketing mix will surely help your online presence stand out in a time where the digital experience is more important than ever.

Email marketing remains a marketer’s most powerful tool. It not only produces an impressively high ROI, it’s also highly measurable. It’s not uncommon to hear people boast about high deliverability as one of these metrics. However what does that statistic ‘deliverability’ actually mean? Statistics suggest that 1 in every 5 emails fail to land in the inbox [1] which means 20% of opportunities to connect with customers are being missed. Having great deliverability is what every marketer strives for but it is something that has been difficult for people to define. Now it’s not uncommon for words to have different meanings in different countries, the most obvious example being football. Deliverability, like football, has many different meanings No wonder Googling the term “deliverability” leaves you more confused than when you started. Metrics and people’s interpretation of their meaning is one of the biggest reasons for confusion around the topic of deliverability and many marketers mistakenly feel secure in their ability to reach subscribers if they have a high delivery rate. This however, isn’t necessarily the case… Delivered vs ‘accepted’ Often what marketers believe to be a measurement of their deliverability is in reality the proportion of emails that were ‘accepted.’ An email is considered to be delivered if it does not bounce or doesn’t get returned to the mail server stating it was unable to be delivered for a specific reason. Delivery rate is a calculation of mail sent minus the volume that bounced. Deliverability is making sure you are doing what you can to put yourself in the best position to be actually seen by your email subscribers. Not stuck in spam or ignored. Inbox placement is an ongoing battle for email marketers and is effected by many factors such as CAN-SPAM, PECR, CASL compliance, sender reputation, list hygiene, authentication and blacklisting. The number of active subscribers, open and click-through rates also can influence reputation with certain ISPs such as Hotmail or Gmail. Successful deliverability depends on a combination of best practices, including authentication and email reputation. The rules of deliverability go through perpetual change and proven techniques can prevent failures. Many people believe there is a silver bullet or a guarantee that a supplier can provide 99% deliverability rates, in reality sending mail to those who want it is the only truly proven way to get great deliverability. Deliverability is a critical element of email marketing and something that all marketers should be considering. Want to learn more about deliverability? Check out our ebook "You’ve got mail! Spotlight on email deliverability," where we offer a proactive strategy for building brand loyality and improving ROI through email deliverability and optimized email marketing programs.

Engagement matters. It matters to marketers and it matters to the consumer…but what is the most effective way to improve that engagement? We sat down with Marketing Expert, Liz McLemore to get her take on the top 5 marketing resolutions to improve your marketing programs. Resolution 1: Gain a full understanding of your data This year, strive to get a full picture of what data you have available. In order to really know who your customers are across all channels and be able to deliver meaningful experiences to them, you’ll need to consider what sources of data are available to you, and then who needs to have access to that data in order to best leverage it. Here are a few tips to get you started: -Collect demographic and behavioral data to get a clear picture of your customers. Combining these data types will help give you a better view of your audience. -Perform a comprehensive data audit to figure out exactly what your data is telling you. Document everything, from the data type to how often it’s updated. -Find a partner who can centralize your database and help you leverage unlimited data types and sources. Resolution 2: Amp up your personalization Your newly centralized data will allow you to better personalize the content and timing of your cross-channel communications. In order to make change executable, consider a phased approach to personalization. -Start small, with elements of your current template that can easily be personalized, such as headers or footers. -Enhance personalization through demographic or behavioral data, such as loyalty points. -Move toward a true 1:1 experience by partnering with a cross-channel communications provider who can help with state-based personalization. Resolution 3: Maintain a consistent approach When your customers interact with your brand, they should encounter a consistent brand experience. They don’t think in channels, so why should you? -View your brand as a customer would. Sign up for your emails, check out the in-store experience, and follow your brand on social media. -Compare your message across channels. Is the story you’re telling consistent? -Examine your internal operations, and work to remove silos. Cross-functional teams need to work together seamlessly in order to deliver a seamless cross-channel customer experience. Resolution 4: Adopt a mobile-first approach in every channel Customers do more than check email on their phones. Mobile commerce is growing, and a Business Insider BI Intelligence report predicts that mobile will account for 45% of all ecommerce by 2020. In order to take advantage of this growth, expand your mobile-first approach beyond the inbox. -Have a well-paved mobile path. Test the look and feel of your emails on a mobile device. Make sure that your website is mobile optimized, and that the path to purchase is as frictionless as possible. -When incorporating an SMS campaign, have a clear goal in mind. SMS campaigns can be effective ways to promote upcoming deals, cultivate loyalty, or inform, but it’s important to narrow your focus in order to best engage your customers. -Be compliant. If you do not have a mobile expert on your team, be sure to partner with one who can ensure your campaigns follow mobile compliance guidelines. Resolution 5: Measure effectiveness Now that you’ve put processes and plans into effect, measure their impact. -Work with your web, mobile, and social teams at the campaign creation stage to determine what metrics you need to measure, and why. In today’s cross-channel marketing world, it’s about more than open and click rates. -Compare your engagement rates to industry benchmarks to gain a better sense of how your brand is performing, but remember you need to be your OWN benchmark. -Invest in more sophisticated analytics programs to take your reporting to the next level, or seek the professional advice of experts who can show you how to separate the signal from the noise and gain deeper insights.
