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.

Americans are still spending more time on Twitter.com than ever before. According to Experian Simmons estimates, Americans spent an estimated 2 hours and 12 minutes tweeting and reading tweets on Twitter.com in November 2010.

As we ring in the New Year this week, Americans will be tossing back a few adult beverages in celebration. While alcohol consumption certainly increases around holidays and other times of celebration, many Americans imbibe year-round. So where across this great land of ours are you most likely to find adults willing and able to raise a glass (or two) and where are you most likely to be surrounded by teetotalers? Experian Simmons has the answer. Leveraging data from our SimmonsLOCAL study, we examined the drinking patterns of adults of legal drinking age in the 106 Designated Market Areas (DMAs) with populations of at least 500,000 adults age 21 and older. We then ranked those markets by the number of alcoholic beverages consumed by the average adult during a typical month. The chart below lists the DMAs that consume the most alcoholic beverages per capita in a typical month. First place goes to Boston, where the average adult of legal drinking age regularly kicks back 14.4 drinks a month. (Celebrations in Beantown are probably already underway.)

The chart below lists the DMAs that consume the fewest alcoholic beverages per capita in a typical month. Residents of Chattanooga consume only 6 alcoholic beverages per month, on average, making it the least imbibing market-and probably the one that feels the best the morning after a big gathering.
