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.

If the time spent on the Internet for personal computers was distilled into an hour then 27 percent of it would be spent on social networking and forums across the United States, United Kingdom and Australia. In the U.S., 16 minutes out of every hour online is spent on social networking and forums, nine minutes on entertainment sites and five minutes shopping. Global comparison In the UK, 13 minutes out of every hour online is spent on social networking and forums, nine minutes on entertainment sites and six minutes shopping. Australian Internet users spend 14 minutes on social sites, nine on entertainment and four minutes shopping online. Across all three markets, time spent shopping online grew year-over-year, but the UK market emerged as having the most prolific online shoppers, spending proportionally more time on retail Websites than online users in the U.S. or Australia. British Internet users spent 10 percent of all time online shopping in 2012, compared to nine percent in the U.S. and six percent in Australia. This was in part due to a bumper winter holiday season in the UK where 370 million hours were spent shopping online, 24 percent higher than the monthly average. Consumption of news content also increased across all three markets with Australian users emerging as the most voracious consumers of news online. Six percent of all time spent online in Australia in 2012 was on a news Website, compared to five percent in the UK and four percent in the U.S. Meanwhile, the time spent on social media proportionate to other online activities declined across all three regions. The U.S., which has been the most dominant market for social media consumption in the last three years dropped from 30 percent of all time spent online to 27 percent. In Australia time spent on social dropped from 27 percent to 24 percent while in the UK it dipped from 25 percent to 22 percent year-over-year. This highlights the rise in access via 3G and 4G networks as consumers spend increasingly more time online while on the move. "Understanding consumer behavior across channels is more important than ever as more visits are being made on the move, particularly among social networking and email,” says Bill Tancer, general manager of global research for Experian Marketing Services. "With smartphones and tablets becoming more powerful, our data clearly indicates the difference between mobile and traditional desktop usage further enabling the ‘always on’ consumer mentality. Marketers need to understand these differences, as well as regionally, to ensure campaigns can be tailored for better and more effective engagement.” Mobile browsing When looking at the U.S. browsing data for mobile devices, email accounted for the largest time spent on average, for the same categories for Q1 2013. Email made up 23 percent of time spent on mobile devices for Q1-13, while social networking accounted for 15 percent. Entertainment had the third highest time spent with 13 percent, followed by shopping with 11 percent and travel with 9 percent. The mobile data does not include app usage, but does include mobile browsing within an app. Read more of the latest consumer trends in The 2013 Digital Marketer Report Learn more about consumer online behavior by visiting our Online Trends page Learn more about the author, Matt Tatham

The 2013 Digital Marketer Report is almost here. One section of the report includes key segments of the consumer landscape. In a previous post we looked at budget and luxury travelers and in this excerpt we focus on millennials – specifically tactics to target early adopter millennials: The generation of 18- to 34-year-olds known as millennials is an increasingly influential group that impacts many aspects of the American lifestyle, including fashion, technology, entertainment and beyond. Almost one-quarter (24 percent) of millennials have a college degree, 34 percent are married and many (60 percent) own a home. They have an average discretionary spend of $11,317 annually. Brands and marketers are taking notice of millennials and the fact that they communicate and behave differently than other generations. Marketers increasingly understand that they need innovative marketing programs in order to engage this important segment of the population Early adopter millennials Fifty-two percent of millennials rank far above or above average when it comes to being early adopters of technology. That means more than half of adults ages 18 to 34 want to be the first to have the latest electronic equipment, are willing to pay almost anything for an electronic product and actively want to be a source of information on electronic equipment to others Marketers trying to reach this group can look at the types of Websites driving millennials to online retailers in order to understand other sites that would be effective partners, advertising outlets and content providers: Millennials are more likely than the online population to visit search and social Websites before visiting a retail Website They are less likely to look at email or visit reward and directory sites before visiting a retail Website They are more likely to visit fashion content and portal sites before visiting a retail Website There is a major opportunity to reach early adopter millennials via mobile, as they spend 14 percent more time engaged with their mobile devices in an average week than their generational peers. Early adopter millennials are 20 percent more likely to use a tablet and 32 percent more likely to IM/chat than the average millennial. Other top activities include reading media, listening to music and email.

The 2013 Digital Marketer Report is almost here. In anticipation of its release, here’s an excerpt from the online display advertising section: Here’s what marketers and advertisers need in order to lay the groundwork for success in their online advertising campaigns: Solid audience-based data is the foundation for display advertising success. Start with your CRM file and work with the right partners who can best leverage it and enhance your audience definition with robust data assets to create a highly targeted display audience. Actionable, value-based segmentation is a key campaign driver. Value-based segmentation assigns predicted economic values to customer or prospect audience targets – based upon the campaign objective – for the more cost-efficient real time display ad buying. Applying value-based segmentation to an audience according to sound consumer insights and analytics allows for more dynamic and cost-effective display media bidding. Scalability to drive campaign efficiency. You’ve defined your target audience with value-based segments. Now you need to reach that specific audience at scale to maximize campaign efficiency and get the most from your media budget. High-quality creative to drive engagement and conversion. Developing the right audience, targeting parameters and media strategy is only as good as the creative message displayed so the importance of highly relevant, targeted creative cannot be underestimated. Work with a partner who understands your target audience and campaign objectives to develop and deliver the most compelling message. Approaching your online display campaign set up this way will ensure it is built on a solid foundation, greatly increasing the likelihood of your program’s success. Keep in mind that data-driven, audience-based campaigns typically take a little more ramp-up time than more traditional advertising. Sometimes, if companies don’t see results right away, they might change or abandon their strategy too quickly. This new, digital path truly requires a shift in advertiser behavior and thinking. All is not lost if you don’t see results right out of the gate. The systems need time to use the data to target the best audience, hone in on the right media for that audience and bid on it accurately. All of these steps take time but are needed to drive performance. Marketers in the trenches may get comfortable as they start to see results, but they sometimes struggle with getting their senior leadership to accept the longer time frame and keep spending on display programs. Brand advertisers tend to buy into display better than performance-based advertisers because they are used to the time required to create repeated exposure that builds awareness, consideration, favorability and intent. The key takeaway is that you need to go into these campaigns feeling comfortable about the longer timeline required to allow traction and drive the results you seek.
