Our next segment in our Ask the Expert series dives into the importance of data enrichment and its benefits across connected TV (CTV) advertising. Ask the Expert features a series of conversations with product experts where we focus on topics that matter the most in AdTech. In our latest segment, Natalia Irmin, Director of Strategic Data & Media Partnerships at a4 Advertising, joins us to chat with Experian’s SVP of Sales & Partnerships, Chris Feo.
a4 is an advanced advertising and data company that offers audience-based, multiscreen advertising solutions for local and national advertising businesses.
In their conversation, Natalia and Chris review:
- The benefits of data enrichment
- First-party data enrichment across advertising
- Data enrichment in CTV advertising
- How Experian and a4 work together
What is data enrichment?
Data enrichment enhances first-party data sets using third-party data sources. This process involves merging first-party data from internal sources with data gathered from other internal sources or from external third-party sources.
Examples of data that can be part of the enrichment process include:
- Demographic information
- Contextual signals
- Behavioral patterns
- Interests
- Purchase-intent
The more you know about your customers, the better equipped you are to reach them where they are with the right message. By enriching your data, you can enhance your messaging, provide personalized offers, and establish a loyal customer base.
First-party data enrichment across advertising
Businesses are transitioning from cookie-based third-party targeting to first-party data enrichment solutions as a result of cookie deprecation. When data enrichment is paired with internal first-party data, you can generate a more holistic customer profile.
a4 has a rich set of first-party data, based on the subscriptions to their services. a4 uses first-party data enrichment across advertising in two ways:
- Measure performance using their viewership data
- Advise their customers on where they should focus their advertising efforts based on the customer’s viewing behavior
a4 supports the enrichment of their customers’ first-party data so they can get the most out of their insights.With Experian’s privacy-first approach, a4 can continue to rely on their first-party data while protecting personally identifiable information (PII).
Data enrichment in CTV advertising
CTV advertising refers to digital advertising that appears through a streaming service during a viewer’s video content, like a movie or TV show. CTV ad campaigns allow businesses to personalize their digital marketing messages while the viewer watches content on various platforms. CTV offers a highly measurable opportunity to increase brand awareness.
Benefits of data enrichment in CTV advertising
Data enrichment provides three key benefits that can enhance targeting, personalization, and campaign effectiveness in CTV advertising.
Understand your target audience
By using enriched data such as demographic information, viewing behavior, and interests, you can gain deeper insights into your target audience, refine your targeting strategies, and create highly personalized ad experiences. Data enrichment also enables better measurement and optimization of ad campaigns, maximizing ROI.
Integrate enriched data with other marketing channels
You can integrate enriched data into CTV with data from other marketing channels. This enables the creation of comprehensive and cohesive marketing strategies that provide consistent messaging and enhance cross-channel targeting.
Enhance the value of ad inventory
Data enrichment can also benefit content publishers and broadcasters by enhancing the value of ad inventory and providing more targeted and effective advertising opportunities.
Enabling your marketers to target specific audiences will result in improved campaign performance. Through data enrichment, you can increase return on your ad spend and boost the value of your publisher’s ad inventory. a4 and Experian can help your business attract additional demand with audience enrichment. a4 uses Experian’s vast offering of audiences and combines it with Experian’s Graph. This data can later be used to activate across a4’s parent company, Altice’s owned and operated properties, as well as beyond Altice’s own footprint via premium publisher partners.

The beginning of any new year brings an influx of gym goers who are committed to working on resolutions. Whether the goal is to work out or be healthier, gyms around the nation see a spike in numbers in the first few months of the new year. Experian examined foot traffic patterns for five gyms nationwide from January to June of 2019 to determine if there were significant trends. Unsurprisingly, there was a spike in visits in January, which correlates with the rise of advertising in the fitness industry during that time. We are all familiar with the ads telling us about the amazing discounts available at our nearest gyms, as well as the constant reminder that it’s a new year so it’s time to reinvent yourself – “New Year, New Me!” Even though the spike in visits in the first couple of months is exciting for businesses, research suggests that these trends won’t continue throughout the year, which means a loss of revenue over the latter half of the year. A loss of revenue is never good, so as a marketer, how can you better understand your new clients and target them when they might be inclined to throw in the towel? Taking a second look at the graph above, you see a spike in visits in late March and early April, before a big drop off in May. We were curious to see what was causing this spike, so we took a deeper dive into the data, looking at both age and gender. What we found was that from January to early March, there was a steady decline in visits, whereas in late March to early April, there was about a 7% rise in visits across the board. What was more interesting than the spike in visits, was the significant drop after the first week of April. We saw a significant 13% drop in visits on average in both males and females of all ages. On the higher end of the spectrum were both males and females between the ages of 19-34 with a 14%-15% drop in visits. While we can speculate on why there was such a drop at this time – right after spring break, etc. – gathering more data about these individuals is essential to building an effective marketing plan to combat this degradation. As a marketing professional in the fitness industry, or someone looking to target a health-conscious demographic, you need to understand your audience – both their visit patterns, as well as their likes and dislikes. Using Experian’s data, you can take a deeper dive to understand your members eating habits. For instance, you can better understand if your clients like to visit health-conscious dining establishments or do they frequent QSR locations like McDonalds. It may seem like common sense, but a successful marketing campaign is rooted in relevant messaging and relevancy is rooted in the ability to understand the target audience. While the goal is to bring new members into your gym or health club in January, the challenge is to keep those new members coming throughout the year, and that’s where there is an opportunity for marketers to better connect with these customers. If you know that people under the age of 34 are at the biggest risk of halting their visits to your fitness location in the middle of April, then you can take the next steps to better understand that demographic so you can activate an effective marketing campaign tailored to their needs before you lose their memberships. The key is to understand who these fitness resolution members are and find a way to target them before their commitment waivers. What works for one location may differ from another, so you have to include other data points in to build a more holistic view of your target audience. At the end of the day, understanding your members is key. Partnering with Experian to take a deeper dive into your members likes and dislikes, as well as their visit patterns can allow fitness locations to have the data and the tools at hand to make the right marketing decisions and deliver an effective marketing campaign, ultimately reducing the membership attrition rate.

Over the past two decades, marketers were consumed with the Millennial generation. Those individuals born between 1980 and 1995 represented a new set of consumers to the market with very different attitudes, behaviors and purchase decision styles than had previously been seen. Marketers invested significant capital to learn about Millennials and transformed their marketing strategy to better reach and attract them. Those that did this successfully were able to grow their business and extend their footprint to a new group of consumers. Now, as we enter a new decade, another generation of individuals is entering into the market and represents the future customer for marketers. Understanding who these consumers are, how to best reach them, and how they make purchase decisions will help marketers reach this new audience and grow their business more effectively. 1. Who is Generation Z? While definitions have varied from different publications, Generation Z is generally defined as consumers born between mid-1990s through early 2010s. Here, we define generations as the following: According to Kasasa, this group represents about 74 million consumers, which is similar in size to other generations.[i] Information on Generation Z is limited since many are still considered minors. However, resources such as syndicated surveys have provided some thoughts about their general attitudes that can begin to provide insight. Key Takeaway: Get to know Generation Z. They are big, they are coming, and they will likely be the future consumer you will need to attract. 2. How is Generation Z Influenced by Technology? Very much so. Generation Z individuals received their first mobile phone at age 10.3 years and spend an average of 3 hours each day on their device.[ii] They have no real understanding of what life was like before the internet. They are active users of smart phones, apps, and social media, and frequently use technology before making decisions. The internet is very important to Generation Z – they meet people, share information about themselves, get their entertainment, relax, and enjoy going online in their free time. Generation Z respondents were more likely than other generations to agree with the following statements: “I like to keep my personal Internet pages updated with information about my life.”“The internet is a good way to meet new people.”“The internet is a main source of entertainment for me.”“Going online is one of my favorite things to do with my free time.” Additionally, the mobile internet, which includes accessing social media and apps through a hand-held device, is even more meaningful to the Generation Z consumer. Generation Z respondents list the following as what the Mobile Internet means to them: “Pure entertainment”“A good escape”“Relaxes me”“Puts me in a good mood”“Keeps me up-to-date with the latest styles and trends” One result of this is how much more connected Generation Z feels with each other, and with celebrities. They actively follow and interact with their friends or celebrities through YouTube, TikTok, Twitter, Instagram, Snapchat or other social media tools. As a result, they are much more influenced by celebrities than other generations. Key Takeaway: Generation Z will be a heavy user of technology and are influence by each other and celebrities. They will expect your products to be accessible through mobile devices. 3. What media channels are best for reaching Generation Z, and what are their decision-making characteristics? To improve marketing effectiveness, marketers must know how to reach their consumers. Two significant dimensions of reach are (1) the preferred channel the consumer uses to gain awareness about a product; and (2) the decision-making style the consumer employs. Using Experian’s TrueTouchSM, marketers can learn this and develop a marketing communication strategy for improved reach. Generation Z is much more engaged through digital media. More than 3 out 4 Generation Z respondents listed the following as their preferred engagement channel: Streaming TVDigital DisplayRadio (including streaming radio)Digital VideoMobile SMS More traditional channels such as email, direct mail and traditional newspaper were ranked very low, indicating that reaching Generation Z will require marketers to move away from more traditional media channels to influence these consumers. Decision-making styles were also different for Generation Z. The most frequent Experian TrueTouch Decision-Making Styles among Generation Z respondents were: Brand loyalty was the least frequent response among Generation Z. This indicates that Generation Z may not have an automatic affinity to a brand, and that marketers may have to demonstrate its value to influence these emerging consumers. Key Takeaway: Digital media will be a key for reaching Generation Z, and marketers will have to adapt away from traditional media to influence these consumers. While recreational and “In the Moment,” Generation Z does not have loyalty to specific brands, considers what goes into products, and researches different websites and online reviews before making a purchase. In summary, Generation Z is an emerging group of consumers that will challenge marketers to think beyond traditionally successful marketing tactics. These consumers were born into a digital age, and are heavily influenced by social media, whether it’s recommendations from friends, or celebrities that endorse a certain product. This influence requires marketers to communicate more digitally, and less from traditional media like direct mail, email and newspapers. Finally, marketers will need to be aware these consumers will make purchase decisions based on research from other websites and online reviews, look for new things particularly those made with natural ingredients, and are not necessarily loyal to established brands. Knowing this will help marketers develop strategies and make the necessary investments to reach this group more effectively.
