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.

Hi, Dana here with an update on my holiday shopping post from before Thanksgiving. Like I thought, I was able to get most of my shopping done that Black Friday weekend. It was all pretty fast and easy, but I did have one not so great experience too. My sister knew I was going to get something for my niece, so when she got an email from Toy World that everything would be 50% off on Black Friday she forwarded it to me to let me know. I was thrilled. I had done some searching for good toys this year and had some ideas. While I normally would shop online, the Toy World coupon said the 50% off was in-store only so I braved the crowds for a good deal. Unfortunately, when I got there I learned that the email was wrong – only select items were 50% off and others were buy one, get one 50% off. I was pretty upset because the hottest toys were the ones excluded from the deal. I came all that way based on the email. I wound up getting a gift, but I could have saved myself the hassle and long lines, especially since I didn’t get a deal that was different from any other day. That was a rough start to the shopping weekend, but, no worries, things improved. I have to tell you about my best shopping experience – I’ve been telling everyone! This year I used Pinterest to see what my mom has had her eye on lately. One of her pins is a food processor and I think that’s a perfect gift for her. I’m a card holder and reward member at Aaron’s department store and I know they carry some really nice kitchen appliances. They also happened to send me great Cyber Monday coupons in the mail – it was perfect timing. I went online on Cyber Monday, used the promo codes from the coupons and not only got great deals, but got free shipping too! How easy was that?! They also sent me shipping notifications so I knew exactly when to expect the package. I am really happy that I got something great for everyone on my list and now have time to enjoy the rest of 2012. I hope you enjoy it too! XOXO, Dana Editor’s note: You can tell that Aaron’s knows Dana. They used their direct mail piece to send her online offers because they know that’s her preferred purchase method. They’ve won her over once again and created a brand advocate. Learn where your company stands in your marketing efforts today, and how you can help move efforts forward to ensure your customers have good experiences like Dana had with Aaron’s, and avoid bad ones like her trip to Toy World.
