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.
How Experian and a4 work together
a4 and Experian have a long-standing partnership that enables a4 to enhance its data. Through our Consumer View and Consumer Sync products, a4 can add audience attributes to its subscriber and viewer data to precisely pinpoint the audience that its clients are targeting. Experian helps a4 in building a comprehensive customer profile, which helps expand the customer base for a4’s advertising clients.
We form partnerships, like we do with Experian, to enhance our data further, so that we can combine the power of the viewership and exposure data for those other attributes that clients might need.” – Natalia Irmin, Director, Data & Strategic Partnerships, a4 Advertising
Through Experian’s audience attributes and Graph, a4 can assist advertisers in targeting audiences beyond their usual reach, creating a better user experience. a4 can personalize experiences and promotions to prioritize customers with a higher likelihood of making a purchase.

Twenty years ago this week, the first mobile text message, or SMS, was sent by British engineer Neil Papworth. Today, Americans are texting more than ever and among young adults, many of whom were not yet born when the first message was sent, texting is almost as common a mobile activity as talking. And why wouldn’t it be? According to the latest Simmons National Consumer Study, 48% of adults ages 18-to-24 say that a conversation via text message is just as meaningful as a telephone call. A similar share of adults ages 25-to-34 feel the same way. Regardless of age, texting is still, technically, the second most common activity that Americans engage in on their cell phone after talking. During a typical week, 95% of mobile adults talk on their mobile phone, while 59% text. Among adults ages 18-to-24, however, 89% talk on their phone and 85% text. Despite the increasing availability of mobile chat or instant message applications, texting remains the dominant means for exchanging short messages. Only 8% of all mobile adults use their phone to IM or chat. The fastest thumbs To get a more in-depth understanding of the texting habits of adults today, we leveraged data from the Simmons Connect mobile panel of 1,485 U.S. smartphone owners. Hands down, young adults text more than any age other age group. During a typical month, in fact, smartphone-owners ages 18-to-24 send 2,022 mobile text messages and receive another 1,831 for a combined total of 3,852 texts sent and received. With every age bracket we move up, the number of mobile texts drops by roughly 40%. For instance, smartphone owners ages 25-to-34 send, on average, 1,110 text messages a month and receive another 1,130 for a combined total of 2,240 messages. We are also able to leverage the Simmons Connect smartphone panel to understand mobile calling behaviors. The data shows that while young adults hold the record for the most text messages sent and received, they actually make and receive few calls, by comparison. During a typical month, smartphone owners ages 18-to-24 make 119 calls on their mobile phone and answer another 64 calls. Adults ages 35-to-44 make and receive the most calls on their mobile phones in a given month. (Call counts do not include inbound and outbound calls that go unanswered.) Text around the clock Unlike television and radio, which have peak hours for reaching consumers, mobile text messages reach Americans throughout the day, providing advertisers with a medium to connect with consumers any time they want or need. No surprise, young adults are the most likely to send and receive mobile text messages throughout the day. The smartphone panel data shows that during every hour between 8:00 A.M. and midnight, more than half of young smartphone owners are both sending and receiving mobile text messages. Even when most of us are asleep, young adults’ smartphones continue buzzing from inbound texts. In fact, 37% of 18-to-24 year-old smartphone owners receive texts at 4:00 in the morning. By comparison, just 20% of smartphone-owners ages 25-to-34 years-old receive texts at this late (or early) hour as do 17% of those 35-to-44, 15% of those 45-to-54 and 10% of those ages 55 and older. Better to send or to receive? During overnight hours, the share of young smartphone owners who send texts surpasses the share who receives them. However, by 8:00 A.M., the difference between those two figures narrows to the point that they are nearly equal. In fact, from noon until 11:00 P.M., young adults are more likely to send mobile text messages than they are to receive them. Call or text? While texting is still a secondary use of mobile phones after calling, that’s not the case all day, especially among young adults. In fact, while smartphone owners ages 18-to-24 are more likely to make an outbound call than they are to send a text from their phone between 7:00 A.M. and 10:00 P.M., they are more likely to send a text between 11:00 P.M. and 6:00 A.M., during hours when they might understandably wake the recipient. That should help us all sleep a little better.

A few months ago, during a conversation with the Simmons team at Experian Marketing Services, we started talking about how Hispanics are influencing the mainstream. Someone threw out the “salsa outsells ketchup” anecdote we’ve all heard, and we realized that it was time to stop reusing the same examples and start trying to really prove whether or not this influence is happening. Not long after, the Latino Influence Project was born. The study leverages a custom analysis of data from the Simmons National Hispanic Consumer Study, which measures over 48,000 respondents across 60,000 variables, including language, demographics, brand preferences, attitudes, lifestyles and even political outlook. Not surprisingly, the data showed that non-Hispanics who live in high-density Hispanic neighborhoods behave, buy and believe more similarly to Hispanics than non-Hispanics living in low-density Hispanic neighborhoods, even after controlling variables such as geography, education, income, age and other factors. Some of our findings reinforced what we expected to see. For example, the data shows that non-Latinos living among Latinos: Consume and enjoy more Hispanic products, including food, music and sports. They are 5.5 times more likely to eat jalapeños and are 6 times as likely to listen to and enjoy salsa and merengue. Enjoy standing out in the crowd and being fashionable. They are twice as likely to say they like to stand out from the crowd and 70% more likely to experiment with new clothing styles. However, we were surprised to see that the Latino influence on the mainstream extends far beyond just food, sports and fashion. Non-Latinos living among Latinos also: Lead the way in technology. They are twice as likely to use their cell phones and the Internet for information and entertainment. Eat less processed food. They are twice as likely to look for organic and natural when shopping for food. Are environmentally conscious. They are twice as likely to buy recycled products. The growing Hispanic population together with the influence they are exerting on non-Hispanics that live around them means that our whole notion of “general market” is changing, and will continue to evolve. We think that’s pretty cool. To find out more about the Latino Influence Project and learn more about what we found (and what we think it all means), please join the Webinar being hosted by Wing and Experian Marketing Services on Thursday November 29th, 2012 at 2:00 EST. You can also download the Latino Influence Project report.
