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

With the increase in alternate channels such as social media, many may think that email is no longer a valuable way to create engagement with consumers. On the contrary, email marketing is still one of the most effective tools for marketers — especially when it is paired with mobile. Experian Marketing Services sends more than 10 billion emails each month on behalf of major brands around the world, which gives us the unique ability to monitor trends in email performance and engagement over time. We report email marketing trends as well as the key performance indicators that shaped the success of the Experian Marketing Services clients’ email programs each quarter in our email benchmark reports. Mobile holds potential for email engagement One of the most noticeable trends that we’ve found in our research is that both mobile device usage and email engagement have increased. According to our Q3 2014 Email Benchmark report, the research also states that 53 percent of emails were opened on a mobile or tablet device in Q3. Although we can see an increase in both engagement and mobile usage, it is too early to tell if they are directly correlated. However, marketers should be paying attention — make mobile your priority, and you may have the ability to stay ahead of upcoming trends. “Because people are so connected with their devices today, it only makes sense that they would want to use their mobiles and tablets to check their emails in real time,” says Shelley Kessler, Manager, Reporting and Analytics, Experian Marketing Services. “This is why it is so important for marketers to adopt mobile optimization into their marketing plans. Without it, their overall engagement and click rates will significantly drop and they may ultimately lose their audience.” Catalog brands see email success with tablets To put the importance of mobile into perspective, let’s dig deeper: During Q3 2014, the majority of email opens occurred on mobile phones or tablets for catalogers, consumer products and multichannel retailers. Specifically, for multichannel retailers, 60 percent of all of their emails occurred on a mobile phone or tablet and 50 percent of their total clicks. Meanwhile, catalogers had the highest percentage of tablet use with 18 percent of email opens and 13 percent of clicks occurring on tablets. Mobile can help create a relationship On a daily basis, a digitally connected customer’s inbox will be overwhelmed with hundreds or even thousands of different messages from marketers. To stick out from the crowd, marketers should be thinking of other ways to engage consumers. Shelley Kessler suggests creating a direct mobile messaging program: “Start a mobile messaging program if you have not already done so. If you have not developed a mobile database, start asking for customers’ mobile numbers in addition to email addresses and other basic information.” By utilizing mobile in ways that have not been done before, marketers have endless opportunities to get ahead of the curve.

Keep an eye out for the upcoming Q4 2014 Email Benchmark Report from Experian Marketing Services which will publish at the end of February.

Marketers: personalization is our duty Customers willingly give brands a lot of information. Some brands collect names, birthdays, message preferences and location in addition to contact information like email address, phone number and physical address. Brands that connect through Facebook and other social media accounts gain access to even more information – a person’s likes, friends/followers, age, demographics and more. Why are so many consumers willing to share this information? In a recent webinar, Ed Kowalski, Senior Director of Strategic Services at Experian Marketing Services refers to this phenomenon as the equitable exchange – customers provide companies with personal information because they believe it will enhance their brand experience. In return, marketers have a duty to responsibly use that data to benefit the customer. Personalization is an oft-discussed strategy in marketing, but many marketers struggle to make it a reality. In fact, a recent study found that 94 percent of companies have challenges relating to personalization. Yet marketers continue to collect more customer data – without a clear plan to utilize any of the data in a personalized context. Consider a brand that collects birthdate as part of its subscription process. As a consumer, I will only provide my birthdate if I can imagine a benefit to doing so. And I can – the brand may send me personalized well-wishes or even a special offer on my birthday each year. Because I’m willing to share my birthdate, I expect that the brand will use that data to engage me on a personal level. If they don’t, I’m likely to feel that the data I shared was not used productively, which will damage my perception of the brand and make me more reluctant to share information with them in the future. This concept extends to behavioral data too. Consumers often realize that companies may have data on their past purchases, browsing behavior and more. With this assumption in mind, they expect this data to be used to create more relevant brand experiences as well. Remarketing campaigns like abandoned cart emails and display ads targeted by browse behavior are increasing in popularity, as 69 percent of marketers in our most recent survey run these types of campaigns. This means customers are coming to expect them. So what does this mean for marketers? Not only is it a best-practice to personalize messaging based on customer data, but it’s often a requirement. Consumers are saying, “Show me that you know me.” As marketers, we need to make good on the unspoken promise of this equitable exchange. It doesn’t need to be hard. Check out the slides below or watch the webcast to learn how brands can begin to implement more personalized, relevant messages today.

John Fetto, our Senior Research and Marketing Analyst, explored the top five lessons from the 2014 holiday season and provided tips to help marketers revamp their 2015 holiday campaigns. 1. Move over desktops, consumers are using mobile to search for deals Deal seeking is moving to mobile where consumers have access to pricing and coupons while they are on-the-go and closer to making a purchase decision. In fact, searches for “mobile coupons” are up 14 percent since July when mobile search data was incorporated. As for timing, peak deal-seeking searches typically occur during the holiday shopping season, but the past two years, holiday and back-to-school were nearly equal. For marketers to not leave money on the table, it is critical to target deals and discounts strategically to consumers who need and want them most. 2. The must-have gifts of 2014 2014 was the year of the "Internet of Things," the rapidly growing trend in devices — beyond smartphones, tablets and computers — that connect to the Internet. In particular there was a big leap this season in searches for portable fitness devices and smart watches were up 235 percent year-over-year. Additionally, searches for smart televisions were up 30 percent and searches for smart home automation devices were up 67 percent year-over-year. Savvy marketers will use these insights to reach customers in a myriad of new channels in 2015. 3. Reach consumers later in the week It’s no surprise that the three busiest shopping days this past holiday season were Cyber Monday, Thanksgiving and Black Friday, each capturing more than 225 million online visits to the Hitwise Retail 500. Diving deeper into significant peak days in December, we found that Tuesday and Wednesday earned top spots as key online shopping days. This gives marketers the ability to reach consumers with more relevant messages later in the week and drive in-store sales for the weekend ahead. 4. Email is the second biggest driver of traffic Email continues to be a strong driver of online traffic. In 2014, search engines drove 41 percent of the traffic to the Hitwise Retail 500, followed by email with 8.15 percent. Looking at the performances by key peak days, email was a strong driver of traffic on Thanksgiving and Black Friday, and social media drove the most traffic on Cyber Tuesday, the Tuesday after Thanksgiving. 5. Mobile is a strong driver of traffic to retail sites Much of the mobile activity on retail sites comes from browsing while shopping, whether it’s for price comparison, inventory analysis or to find store hours or locations. In fact, a new study from Experian Marketing Services found that 83 percent of cell phone owners now engage in shopping activities on their phone immediately before, during or after visiting a store. In addition, 53 percent of smartphone owners visit shopping websites from their phone during a given month versus 41 percent who use shopping apps during the same time frame. While mobile apps are great ways for marketers to interact with existing customers, mobile web is critical for reaching potential new customers. Marketers who focus their mobile efforts on developing mobile apps at the expense of mobile optimized sites are likely missing the opportunity to attract new shoppers.
