Digital marketers face an ongoing challenge in the form of “walled gardens,” closed online ecosystems where it is difficult to access user data. As we get ready for 2024, it’s more important than ever for marketers to evaluate the current challenges and opportunities surrounding walled gardens and to take stock of the impact of walled gardens in marketing as an industry.
What is a walled garden?
A walled garden is a closed online ecosystem controlled entirely by one tech company. Advertising on these ecosystems is fairly locked down, as major tech companies with walled gardens tend to tightly control access to the user data, content, and advertising that appears within the ecosystems.
Some examples of walled garden ecosystems include Google, Facebook, Amazon, and Apple. These walled gardens have particular advantages, like access to massive user bases and precise targeting within the individual ecosystems. It can also be difficult to reach said audiences outside of the ecosystems, reducing the amount of control you have over your advertising strategies.

Integrated marketing is more important than ever
Today, it’s become more crucial to connect with consumers over multiple touchpoints, which can be done from tech like connected TV (CTV) to websites, mobile devices, and even shopping in a physical store. However, as integrated marketing gains utility, many platforms with walled garden ecosystems have increased, making a truly integrated and personalized marketing strategy more difficult in many situations. As a result, many marketers have realized the value of a more streamlined marketing approach, emphasizing the importance of fully integrated advertising strategies.
Though there are surely marketing advantages to gain from walled garden ecosystems, especially in audience size, the challenges they pose will require you to innovate and find more creative ways to engage with your audience from platform to platform.
Perspectives on walled gardens from Cannes Lions 2023
Offering a poignant view of industry trends and ideas, the Cannes Lions International Festival of Creativity of 2023 had much to say about the significance of walled gardens in the marketing world. Let’s look at two key takeaways from this year’s festival.
Retail media
In recent years, many retail companies have started selling ad space within their own walled garden shopping platforms, dubbed “retail media.” Platforms like Amazon and Walmart have developed their own particular advertising ecosystems where they sell ads to marketers within the shopping environment itself.
Navigating the sell-side of retail media’s walled gardens
While retail media offers marketers unique opportunities, it’s not without its challenges. For one, ad space in these environments is limited, so the competition can be difficult on the sell-side, leading to higher ad costs. Additionally, this shift in dynamic also forces marketers to change how they prioritize their marketing channels, looking closer at the results of their efforts rather than focusing on particular channels within the platforms themselves.
Opportunities in the buy-side of retail media’s walled gardens
Brands on the buy-side see various benefits from advertising within retail media channels and walled gardens. By browsing in an online shopping environment, the users in these ecosystems are likely high-intent shoppers, people who are further down the sales funnel and who are ready to make a purchase soon. Shoppers can also be precisely targeted within these environments, as marketers are given the ability to access very specific audience segments based on details like shopping behavior, preferences, and even purchase history.
Omnichannel marketing
To more effectively engage audiences even among an abundance of walled garden ecosystems, speakers at the 2023 Cannes Lions Festival discussed the importance of omnichannel marketing. By emphasizing strategies that reach the consumer through multiple touchpoints, marketers can deliver a unified brand experience across channels. This allows marketers to focus more on results than specific advertising channels, including walled garden platforms.
Walled gardens aren’t going away in the near future
Though various challenges are associated with walled gardens in advertising, they aren’t going anywhere. So, what’s the current state of these environments throughout the industry?
Efforts are being made to break down walled gardens in tech
In a handful of countries, regulatory actions have been put forward to address how dominant many major tech companies are in their respective markets. One major example of this is Meta and Google’s entanglements in Canada. Currently, neither company can display news on their websites in the Canadian market. This decision was reached to give Canadian news agencies more control over their advertising revenue since, previously, the tech giants received more views and, therefore, gained the ad revenue. Though relatively small, this does indicate a certain shift in dynamic.
Why companies are resisting
Despite their challenges, walled gardens in 2023 persisted, mainly because they are particularly adept at generating revenue for the tech companies that control them. In 2022, 78 percent of global digital advertising revenue came from these closed ecosystems, and projections expect that figure to rise to 83 percent by 2027. From the viewpoint of a company that operates in a walled garden, the idea of releasing their control over their environment represents losing out on a stream of vast revenue, making letting go of a walled garden ecosystem an unattractive prospect.
The future of walled gardens
As time progresses, what can digital marketers like you expect from walled garden ecosystems in the near future?
A cookieless future
A huge element to consider is the transition to a cookieless future. Many major browsers have begun phasing out the use of third-party cookies. In the wake of this decision, many are looking for reasonable alternatives that allow for behavior tracking and more personalized advertising experiences. Solutions like Experian’s identity resolution can provide a strong alternative option, allowing marketing strategies to adapt to the current landscape.
An influx of mini gardens
You should also anticipate the proliferation of various smaller, specialized walled garden ecosystems in the future. These so-called “mini gardens” specialize in more niche audiences and industries, and they can present their own challenges and opportunities.
Alternative IDs
As you search for new identification methods outside cookies, various alternatives have presented themselves, requiring further exploration and experimentation. Among these are privacy-compliant solutions like Unified ID 2.0, which allow you to serve more personalized ads without compromising the consumer’s privacy.
Navigating the evolving landscape of walled gardens in 2024
As we begin 2024, you will continue facing opportunities and challenges regarding walled gardens. The 2023 Cannes Lions International Festival of Creativity re-emphasized how important it is for marketers to stress omnichannel marketing within walled garden environments and become well acquainted with identity resolution solutions as we move into a cookie-less future. All of this requires you to become comfortable with walled gardens being here to stay and innovate to navigate an evolving and developing landscape.

Marketing without segmentation is a lot like shouting into a crowded room and hoping the right person hears you. Without a clear way to communicate in a noisy marketing environment, your message gets lost in the mix. With segmentation, you can identify your target audience, speak to their needs, and deliver the right message at the right moment. Companies that use segmentation are 130% more likely to understand customer motivations, resulting in more effective campaigns and deeper audience relationships. In this article, we’ll break down four of the most effective customer segmentation methods, when to use each, and how Experian’s audience solutions can help. What is segmentation in marketing? Segmentation is the process of splitting a large audience into smaller groups that share similar traits, like demographics, location, behavior, or firmographic characteristics. As a marketer, these segments enable you to choose channels, messaging, and offers that resonate with each group. Whether you’re targeting new homeowners in Texas, loyalty shoppers in retail, or small business decision-makers in finance, segmentation helps you stand out to them and get results. Why should marketers segment their audiences? Effective audience segmentation fuels accuracy, performance, and personalization at scale. Here's why you should invest your time and marketing budget in honing your audience segments. Maximize your marketing ROI Nobody wants to waste money talking to the wrong crowd. Using various methods of segmentation, you can focus on those who want to hear from you — and the payoff can be huge. For marketing channels like email, segmentation can drive up to 760% more revenue than non-segmented campaigns. The more targeted your message, the better the return. Create a unified omnichannel strategy Segmentation helps ensure that every channel, from email and social media to display, SMS, and direct mail, operates from the same playbook. Once you define your target audience segments, you also need a trusted identity partner to sync them across platforms and environments. This ensures you can deliver consistent, personalized experiences at every touchpoint and your audience receives the same message in the proper context, regardless of where they engage. Strengthen customer loyalty Roughly 75% of consumers are loyal to brands that “get” them. When you strive to understand your customers, they’re more likely to stay. Segmentation enables you to personalize communications based on your target segment’s values, behaviors, or preferences, encouraging repeat business. Expand into new markets With segmentation, you can analyze existing customers to identify common traits and use that data to pinpoint similar groups in new regions or markets. For example, if your top customers are middle-class parents in suburban areas, you can target lookalike segments in other cities with tailored messaging. This makes it easier to expand with confidence, knowing you're reaching people who are more likely to convert. Lower customer acquisition costs Rather than forcing you to cast a wide net, segmentation enables you to focus your budget on high-potential audiences across channels, reduce acquisition costs, and minimize wasted spend on low-intent audiences. Four segmentation methods and examples Let’s look at four different methods of market segmentation. We’ll define each, share when to use them, and give real-world examples to help you apply them. 1. Demographic segmentation Demographic segmentation breaks your audience into groups based on gender, income, age, education, marital status, occupation, and household size. It’s one of the most foundational segmentation methods because it’s easy to implement and often tied directly to buying behavior. Demographic data makes it easier to get the tone, offer, and channel right from the start. And when you combine demographic segmentation with other segmentation methods, such as behavior or location, the impact multiplies. When to use it Use demographic segmentation when your product or service is clearly more relevant to people in a specific life stage, income bracket, or household type. Among all methods of market segmentation, demographic data is often the easiest starting point. It’s especially effective for industries such as financial services, healthcare, education, retail, and others, where consumer needs change based on demographics. Examples As a real-world example, a health supplement company used Experian data to segment its ambassador program audience into four demographic groups based on lifestyle and household makeup. These included younger singles, value-seeking families, high-income spenders, and older empty nesters. Applying these insights at registration allowed the brand to deliver personalized, channel-specific communications that boosted acquisition and retention. The approach led to stronger engagement and more meaningful customer connections. 2. Geographic segmentation This method of market segmentation categorizes people by location, including country, region, state, city, zip code, or even climate. It’s a simple yet effective way to tailor your marketing, as location often influences everything from lifestyle and language to shopping habits and product needs. It’s most often used among brands with physical locations or region-specific campaigns. Whether you're promoting snow boots in Colorado or sunscreen in California, geographic segmentation helps you stay relevant to the local context. When to use it Geographic segmentation is ideal when your offer or message changes depending on climate, culture, availability, or local regulations. It’s also helpful for planning market expansion or testing the performance of different methods of market segmentation across regions. Examples One home furnishings retailer partnered with Experian to understand how customer needs varied across store locations. Using a mix of client data and Experian demographics, we segmented stores based on their surrounding customer base, like urban, white-collar shoppers in metro centers versus lower-income households in more remote cities. These insights enabled the retailer to tailor inventory, marketing strategies, and ad copy for each store type, resulting in more relevant customer experiences. 3. Behavioral segmentation Behavioral segmentation centers on how people live their lives — their interests, habits, and decision-making patterns. It includes factors like past purchases, engagement frequency, brand loyalty, product usage, browsing patterns, and responsiveness to offers or promotions. Among all of the segmentation methods, this one provides insight into intent, helping you go beyond who your audience is to understand what they do. You can use behavioral insights to re-engage former customers with relevant offers, reward loyal buyers with personalized perks, or guide high-intent shoppers toward conversion with timely nudges. When to use it Behavioral segmentation is best when you want to personalize based on intent, habits, or engagement stage. It's particularly useful for retention, reactivation, or cross-selling strategies. Examples In practice, a national big-box retailer partnered with Experian to better understand customer behavior during grocery store visits. The goal was to identify distinct “trip missions” that could drive category trial and increase basket size. We analyzed everything from basket contents to customer composition and segmented visits into 11 unique missions. For example, the “All Aisles Online” segment represented large households (often homeowners with families) stocking up on household staples through online orders. In contrast, the “Marketable Mission” segment captured smaller, likely renter households making quick trips for non-essentials. These behavioral insights empowered the retailer to adjust promotions based on the intent behind each visit, strengthen customer relationships, and drive growth. 4. Firmographic segmentation (B2B) Firmographic segmentation is like demographic segmentation for businesses. It groups B2B audiences based on attributes such as annual revenue, location, company size, industry, and organizational structure. You can also segment by job title or decision-maker role to better target key stakeholders. This method is great for aligning your messaging, sales strategy, or product offerings with the unique needs of various business types. A startup in the tech sector will likely respond to a very different pitch than an enterprise manufacturer, and firmographic data helps you speak to both with precision. When to use it Use firmographic segmentation when marketing to other businesses, especially when your product or service has different benefits depending on business size or sector. Examples Recently, a B2B client partnered with Experian to gain a deeper understanding of the revenue potential of their existing business customers. Using firmographic data, we segmented the client’s customers into distinct groups based on the characteristics most strongly tied to spending behavior. For each segment, we calculated potential spend, defined as the 80th percentile of annual spend within that segment. This allowed the client to identify high-value accounts with untapped growth potential. For example, one customer, ABC Construction, had spent $4,750. But based on their segment’s profile, their annual potential was $9,000. That insight revealed a $4,250 opportunity to deepen the relationship through more targeted marketing and sales efforts. Best practices for market segmentation Regardless of the segmentation method you use, the following best practices will help you maximize the benefits of your efforts. Start with clean, reliable data Segments are only as good as the data behind them. If your data is outdated, inaccurate, or incomplete, your segments will result in ineffective targeting and a wasted budget. Utilize accurate, compliant, up-to-date sources like Experian Marketing Data, ranked #1 in accuracy by Truthset, to ensure your targeting is on point. Test and refine segments continuously Business goals, market conditions, and behaviors are constantly changing. What worked last month or even last week might not work today. By adjusting your segments over time, you make sure your marketing stays relevant, focused, and effective. Use A/B testing, performance metrics, and audience analytics to iterate on your segments and improve results over time. Align segments with personalized messaging and offers Each segment has distinct needs, preferences, and motivations, which means generic messaging won’t resonate effectively. Once you’ve built your segments, personalize your creative, copy, and offers to appeal to each group and increase the likelihood of engagement and conversions. Integrate segmentation across all platforms If someone sees one message in an email and a completely different one in an ad or on your website, it creates confusion and weakens trust. From CRMs and email platforms to ad tech and analytics tools, make sure your segmentation method is applied consistently across every channel to improve performance and build a cohesive brand experience.
