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.

Today, it costs more than $40 to send a five pound package from the U.S. to Canada or Mexico. The cost to Europe or South America is even more expensive. For U.S. companies operating on a global scale, such as retail specialists or ecommerce organizations, address accuracy is crucial. Organizations can’t afford undeliverable mail and packages due to a wrong address – the total cost would be unmanageable. Mistakes happen frequently, whether it is an error by the company or the customer. If a mistake is made, companies can’t ask the customer to cover delivery fees, leaving the organization with the bill. Retailers must also consider potential delays due to long distances and custom checks. Altogether, address errors result in a poor customer experience and a decrease in efficiency. Implementing international address verification will save money, time and improve the customer experience. By combining primary address data from national postal authorities with partner-supplied data, businesses can verify international addresses from countries all around the world.

On April 22nd, Americans and many of their terrestrial counterparts in countries around the world will celebrate Earth Day, a tradition that was started in the United States by Wisconsin Senator Gaylord Nelson in 1970. Much has changed on the planet since the first Earth Day, and even in recent years attitudes continue to evolve when it comes to our outlook towards the environment. In 2007, Experian Simmons created the GreenAware consumer segmentation, which classified respondents to the Simmons National Consumer Study between 2005 until 2007 into one of four mutually exclusive segments based on their consumer behaviors and attitudes toward the environment. Since then, Experian Simmons has continuously classified all adult respondents into the GreenAware segments providing our clients with valuable insights into the evolution of the environmental movement. The four GreenAware segments are: Behavioral Greens: This group of people thinks and acts green. They have negative attitudes towards products that pollute and incorporate green practices into their lives on a regular basis. Think Greens: This group of consumers think green, but don’t always act green. Potential Greens: This group neither behaves, nor thinks along particularly environmentally conscious lines and remains on the fence about key green issues. True Browns: They are not environmentally conscious, and may in fact have negative attitudes about environmental issues. Since 2005, we have observed a nearly constant increase in the percent of U.S. adults who are classified as Behavioral Greens, the “greenest” segment of the four. Today, 33% of adults are Behavioral Greens, up from 27% who were classified as such in 2005. Meantime, Think Greens have maintained an almost perfectly constant 21% share of the population. The size of the True Browns segment has also remained constant at between 14% and 15% of the total adult population. The Potential Green segment, however, has steadily declined in market share from 39% in 2005 to 31% today. La Vida Verde Hispanic Americans have traditionally been ahead of the curve when it comes to green thoughts and deeds and they’re only getting greener with time. Today, 39% of Hispanic adults are Behavioral Greens, up from 33% in 2007. Just 32% of non-Hispanic adults are Behavioral Greens today, up from 29% who fell into the greenest segment in 2007. Interestingly, among the True Browns segment there are virtually no Hispanics to be found, and, in fact, while the True Brown population is actually growing among non-Hispanics, Hispanics are increasingly moving to greener segments. Specifically, just 1.3% of Hispanics are True Browns today, down from 8% who registered as such in 2007. By comparison, 17% of non-Hispanics are True Browns today, up from 14% in 2007. Green Today, Greener Tomorrow? The illustration below shows the alignment of America’s largest metropolitan areas with the four GreenAware segments today and in 2007. We see that residents of the San Francisco-, New York- and Miami-areas are the most likely to be in alignment with the Behavioral Green mindset today. Denizens of Washington, D.C., Los Angeles, Chicago, Philadelphia and Boston tend to fit more closely with the Think Green set that has green attitudes and intentions, but not always the actions to back it up. But things are changing. In fact, since 2007, we’ve seen that as local minds change, some cities become aligned with a different, often greener, segment. Let’s look at Chicago, for instance. In 2007, Chicagoans’ environmental outlook was more reflective of a mix of Potential Greens and True Browns. Since then, local attitudes have changed so much that Chicago-area residents are now more aligned with Think Greens and Behavioral Greens. Likewise, Cleveland, which was clearly a True Brown town in 2007, now falls in step with the Potential Green segment. In five years’ time, who knows? Cleveland could be America’s next green leader. Not brown now towns Looking at markets large and small with the biggest drop in concentration of True Browns, we see that attitudes in inland markets located in Gulf States have become disproportionately less brown since the Deepwater Horizon oil spill in 2010. In fact, seven of the ten Designated Market Areas (DMA) that saw the biggest decline in the percentage of their population classified as True Browns between 2007 and 2011 are inland markets in states bordering the Gulf of Mexico. While the oil didn’t directly reach these markets, the attitude change did spread: For example, 3.2% of adults residing in the Columbus-Tupelo-West Point, Mississippi DMA today are classified as True Browns, down from 19.3% who were categorized as such in 2007. In Macon, Georgia, while not a Gulf State, a more impressive shift took place. In 2007, the Macon, Georgia DMA had the fourth highest percentage of its population classified as True Browns (20.1%) out of 209 DMAs. Today, only 5.8% of area residents are True Browns, which makes it the market with the 10th lowest concentrations of True Browns in the nation. Macon still has one of the lowest shares of residents who are Behavioral Greens in the nation, but what a difference a few years makes. While the towns directly in the path of the oil spill are not among those with the biggest relative decline in True Browns, area residents’ attitudes did take on a greener hue since the spill. Today, 8.4% of residents in Panama City are True Browns down from 17.3% in 2007. Likewise, only 9.8% of adults in both the Mobile-Pensacola and Biloxi Gulfport DMAs are True Browns down from 17.3% and 19.0%, respectively, who fell into the least green segment prior to the spill.
