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. By tailoring messages and promotions to individual customer preferences, businesses can improve their advertising efforts and deliver them through their preferred channels.

Experian Marketing Services Consumer Expectation Index shows positive outlook for 2012 holiday season Today we released the newest Experian Marketing Services’ Consumer Expectation Index (CEI) analysis of the first half of 2012. As noted in the release, during the first six months of 2012 we reported that consumer optimism has reached an all-time high over the last four years, beating 2008 by 8 index points. The CEI provides us with unprecedented insight into our economic outlook by who we are; men versus woman, age, household income and employment status, to name a few of the 60,000 variables that we have access to. What’s most striking about today’s release is that optimism is up across the board among men and woman and all age groups; even the unemployed increased their economic outlook from an index of 87.6 to 88.0 from the first half of 2011 to the same period this year. As we approach the holiday season, the latest CEI figures indicate a strong seasonal performance for retailers. The CEI figure for the week of Sept. 3, 2012, (the most recent single week for which data is available) was 7.4 points higher than it was at the same point last year and higher than it has been heading into the holiday season since 2008. This holiday season also could be very good for brands and retailers with big-ticket items to sell Further, key consumer groups are even more optimistic. On Sept. 3, the CEI of those adults who made an online purchase in the past year was 2 percent higher than the national average and 8.1 points higher than the CEI recorded for online shoppers at this time during 2011. This holiday season also could be very good for brands and retailers with big-ticket items to sell, since the CEI among adults planning to make a big-ticket purchase hit 117.9 the week of Sept. 3, 2012, compared with 103.5 the same week in 2011 and 100.5 in 2010. In fact, a CEI above 100 indicates that consumers are more confident than they were during the base line period, which was the first half of 2004, years before the recession began. Perhaps it’s all the talk of the looming fiscal cliff that makes today’s release appear to be counter-intuitive. In fact searches for “fiscal cliff” increased over ten-fold comparing last week to the week ending November 3rd. However, if we look for what people were searching for using search term variations, the top searches were “what is the fiscal cliff” and “fiscal cliff definition,” showing that consumers are still learning what the fiscal cliff is and what it means for them. Hitwise "Fiscal Cliff" Search Term Variations Rank Search Term Percent Volume 1 fiscal cliff 48.07% 2 what is the fiscal cliff 6.74% 3 fiscal cliff definition 6.58% 4 fiscal cliff 2013 6.28% 5 obama fiscal cliff 2.83% 6 what is a fiscal cliff 2.40% 7 the fiscal cliff 1.13% 8 what is fiscal cliff 1.06% 9 fiscal cliff looms 1.03% 10 fiscal cliff defined 0.77% Note – data is for the 4 Weeks Ending November 10, 2012 Source: Experian Marketing Services As the population becomes more educated on the looming crisis, we’ll keep tabs on any resulting changes to consumer optimism, specifically which demographics are most concerned.

It is time for us to polish off our crystal ball and give our predictions straight from consumers’ fingertips for the hot products of the 2012 holiday season. Gadgets will reign across many ages Tablets including LeapPads, Tabeos, iPads, Kindles and others will continue to be a popular gift this year, with more choices than ever. On the list of top product-related search terms driving traffic to the Retail 500 category of sites, Kindle Fire HD and Windows 8 top the list as new products. Additionally, Meep!, a child friendly tablet appeared in the top fifteen. Accessories for both phones and tablets will also be popular, especially as the variety grows for iPhone 5 and iPad Mini. A reoccurring favorite gift for the holidays is UGGs which shows a decrease year over year. However, another brand with a similar product is Bearpaw, which is in the top ten searches and has seen big growth year over year. Source: Experian Hitwise Dolls, video games and Furbys, oh my! To identify the popular toys for gifts this year, we researched product-related search terms driving traffic to ToysRUs.com compared to last year’s holiday season. We uncovered trends in the doll category, Doc McStuffins as number one on the list, along with the classic Barbie, which saw a growth in searches year over year. The Furby is making a strong comeback at the number two spot with a reboot and new features. Another trend here is tablets, from branded searches like LeapPad and Kurio there is also the generic term ‘tablets for kids’. In the video game category, the new Wii U that is debuting just in time for Black Friday and should be a big gift this year, along with searches for PS3 games and the Nintendo 3ds xl are all in the top 20 searches. Source: Experian Hitwise Keywords of the consumer to identify demand Beyond product names, it is important to understand the actual way people search, using key phrases and questions. Last year, for example, there was a lot of activity around ‘in-stock’ products, such as the LeapPad explorer, which was hugely popular and quickly sold out in many stores. Retailers and marketers should monitor this throughout the season and make sure to optimize for in stock if there is a popular product that they have available. Source: Experian Hitwise Consumers also focus on what is the ‘best’ – so we see search activity around ‘best place to buy’, particularly around electronics. Questions such as ‘where to buy a’ specific product are also common, such as ‘where to buy a kindle’. These phrases offer opportunities to boost search campaigns by considering how consumers phrase their questions to ensure to capture these searches. Source: Experian Hitwise Quick tip: In the retail category there will tend to be a lot of retail branded store terms but to keep up with holiday search behavior and help make analysis quick, create portfolios of branded terms to easily exclude those from a certain category. When you strip out all the variations of that term you are able to gain insight into product searches that are most popular to a certain site or category.

The holiday season – a most wonderful time of the year for retailers – is underway and marketers are tweaking their campaigns for better customer engagement and enchantment. There are many channels in which to reach top customers and prospective customers, and the new holiday season is a great time to refine strategies and tactics to ensure success. To help marketers in their quest, Experian Marketing Services recently conducted a market research study and learned that email marketing trumped all other tactics as the most successful initiative during the 2011 holiday season. Of the 84.2 percent who used email marketing, 95.8 percent reported that their campaigns were successful. Ninety-three percent said they planned to increase or maintain the same level of investment for the 2012 season. In addition to email, the study showed that paid search and online display advertising were the next most successful marketing tactics of the 2011 holiday season, with 48.9 percent naming search and 34.8 naming online display advertising as extremely or very successful campaign tactics. Our internal experts are currently looking at real-time data around these and other marketing channels and will present what they’ve learned during a live webinar on Thursday, October 25th at 1:00 p.m. EST. This information should prove very helpful to marketers who want to improve their campaigns based on current trends and results. Register for the holiday webinar and you’ll receive all of the survey data in the form of a 2012 holiday marketing white paper. Here’s to a joyous and profitable holiday season!
