As the digital ecosystem becomes more complex, managing multiple identifiers for consumers has emerged as a significant challenge. From cookies and IP addresses to mobile IDs and universal IDs, marketers and platforms face increasing difficulty in maintaining a unified view of their consumers. Without a coherent identity strategy, campaigns can suffer from poor targeting, limited personalization, and flawed attribution.
Experian understands these challenges and offers solutions to help our partners navigate the complexities of a multi-ID landscape. By utilizing both digital and offline data, we provide the tools to unify fragmented identifiers and maintain a persistent view of consumers. As a result, marketers and platforms get rich insights, accurate cross-device targeting, improved addressability, and measurable advertising.
The shifting identity landscape
For years, the industry has relied on cookies to identify consumers across devices and platforms. However, with ongoing signal loss, including the uncertainty around cookies, and the evolution of privacy regulations, the digital identity landscape has grown more complicated. As consumers hop from one device to another, they are now represented by multiple signals, each tied to a different aspect of their digital behavior.
While this shift brings complexity, it also opens the door for innovation. Marketers and ad platforms now have the opportunity to rethink their identity strategies and adopt more flexible approaches that are not reliant on a single identifier.
This is where Experian comes in.
Connecting the dots: A holistic view of the customer journey
Our identity solutions are designed to help manage today’s multi-ID ecosystem by connecting digital and offline identifiers to a single customer profile. This creates a unified view of the consumer, and when combined with our understanding of customer behavior (e.g. demo, interests, shopping patterns) marketers and platforms get both insights about their customers and the addressability to reach them across channels.

Four examples of what you can do with a strong identity foundation
- If an advertiser wants to make its first-party data more addressable, it can utilize our Digital Graph with universal IDs, hashed emails (HEMs), and connected TV (CTV) IDs to extend its reach.
 - A publisher who wants to gain further insights into their audiences and create private marketplaces (PMPs) can achieve this goal with the use of our Digital Graph with hashed emails, universal IDs, mobile ad IDs (MAIDs), CTV IDs, and IPs. The publisher can use this in concert with Marketing Attributes to understand age, gender, household income, buying behavior, and more. The publisher can connect marketing attributes to the Digital Graph via our Living Unit ID (LUID) to understand more about consumers that fall into their segments.
 - A demand-side platform (DSP) who wants to extend first-party and third-party audience reach across all digital devices on their platform will use the Digital Graph with all digital IDs to allow users of their platform to select cross-device extension against first-party and third-party audiences.
 - A retail media network (RMN) can use our Offline and Digital Graphs to connect in-store and online purchases to a household profile—even when purchases are made by different people. The RMN can then reach that household across digital media platforms and accurately attribute the in-store purchase back to digital ad exposure.
 
Identity as a strategic asset: Today and in the future
In our paradoxical world where consumers are represented by multiple identifiers, yet marketers and platforms face signal loss, identity is more than a technical issue—it’s a strategic asset. The ability to unify identity data into a single profile provides marketers with the customer intelligence needed to drive growth and stay competitive. Here’s how we do it:
- Deep, persistent customer understanding: With roots in offline, deterministic data like names, addresses, and emails, we provide an accurate and persistent view of identity to our customers. This allows you to maintain a consistent and comprehensive understanding of your customers and their marketing attributes over time.
 - Highly accurate and refreshed digital identities: Our signal-agnostic graph is not reliant on any one signal as it includes HEMs, cookies, MAIDs, IPs, Universal IDs, and CTV IDs. Our Digital Graph is updated weekly, ensuring the data is always fresh and addressable. This persistent linkage of individuals and households to their identifiers and devices means your campaigns are always targeting the right people.
 - Connected offline and digital graphs for holistic insights: We connect offline and digital identities by following privacy-first best practices, such as preventing re-identification, to allow insights from the offline world to be used in the online world. This integrated approach, enriched with marketing data, gives you better insights, more addressable advertising, and the ability to engage customers across multiple devices while accurately measuring campaign impact.
 
Transform challenges into opportunities
The rise of the multi-ID landscape presents both challenges and opportunities for the advertising industry. We stand as the trusted partner to navigate this complexity, utilizing insights from the offline world to inform decisions in the online world, enabling personalized marketing and accurate attribution, and helping you achieve your current and future goals.

Forward thinking marketers leverage the power of social networking sites like Facebook, MySpace, Twitter and more to connect to consumers in a more personal and meaningful way. That's why Experian Simmons is focusing on social networking in this issue of Consumer Insights, featuring the freshest insights available from the latest Simmons New Media Study. The 2010 Social Networking Report provides the hard data behind this consumer revolution, including the fact that fully 66% of online Americans use social networking sites today, up from just 20% in 2007. Social networking is an increasingly addictive activity, with nearly half of those who access such sites (43%) reporting that they visit them multiple times per day. While users of social networking sites may have initially signed up to better keep in touch with friends, a growing number say they now use sites like Facebook to connect with family members. An astounding 70% of social networkers keep in touch with family via their various online networks, up from 61% a year ago. Fully two-thirds of all online adults today have visited a social networking site in the last 30 days, up from 53% in 2008 and 20% in 2007. Social networks have most thoroughly penetrated the young adult market, as nearly 9-in-10 online 18-to 34-year-olds visit such sites today. But even older Americans are tapping into social networks, with 41% of online adults age 50 and older making monthly visits to sites like Facebook, MySpace and Twitter. The rise of social networking tracks closely with that of Facebook. As of April 26, 2010, 46% of the U.S. online adult population reported having visited Facebook in the past 30 days. While keeping in touch with others is an important part of social networking, the popularity of games like Farmville and Mafia Wars illustrate that fun is a big part of the appeal of social networking. Whether it’s keeping in touch with others, playing games, debating politics or any of the other reasons people use social networking sites, it cannot be denied that there’s a sense of addictiveness to it all. Visiting social networking sites multiple times a day is up 28% over last year, while less frequent visits are down across the board. As social networking sites extend their reach across generations, Americans are increasingly using such sites to connect with more than just their friends. Today, 17% of social networkers communicate with their parents via those sites and 22% connect with their kids, up from 9% and 15%, respectively, a year ago. An astounding two-thirds of social networking site visitors (68%) say they have shown their support of a product, service, company or musical group by becoming a “fan” or a “friend” on a social networking site. One year earlier, only 57% of social networkers had publicly declared their “like” for a product, service, company or musical group. Knowing that social networkers are comfortable connecting with products and brands they support, it's important to understand which brands have the best opportunity to connect with this group. Top retail brands among Facebook users, for instance, include H&M, Hot Topc and Forever 21. Specifically, Facebook users are full twice as likely as the average American adult to shop at H&M. Twitter visitors are 3.7 times more likely to shop at Nordstrom. Heavy users of social networking sites are primarily concentrated in the Northwest and markets that are heavily influenced by major colleges or universities.

The vast majority of Facebook visitors—like most Internet users—say they like websites that take special care to protect their privacy. Yet as the popularity of Facebook grew during 2009 among both younger and older adults, there was a general waning in visitors’ advocacy of online privacy. In fact, the share of Facebook visitors sensitive to privacy protection experienced a 9% relative decline between January and November of 2009. That decline may have continued, were it not for a series of privacy policy updates issued by the social networking giant. In November 2009, Facebook changed its default settings to publicly reveal a larger than before amount of its users’ information. Then in December 2009, the privacy settings were entirely removed from certain categories of users' information. And lastly, in April 2010, users’ General Information became publicly exposed whenever they connected to certain applications or websites, a move that seriously angered many Facebook adherents. Following these changes, the share of Facebook users who are sensitive to privacy protection rose. Specifically, between November 2009 and April 2010, the percent of users who like sites that protect their privacy increased a relative 7%. Facebook’s decision to return, and even simplify, control over privacy settings to account holders may appease users, but whether a subsequent drop in support of online privacy will ensue down the line is far from certain.

Same-sex marriage is a hot button topic no matter on which side of the issue you stand. But there can be no denying that same-sex couples are finding an expanding number of options in the U.S. and abroad should they decide to legally wed. The 2010 LGBT Consumer Report explores the household arrangements and behaviors of America's LGBT consumers—in particular, those associated with marriage—compared to America's heterosexual population. You will learn that despite being less than half as likely to be married, lesbian, gay and bisexual adults are 22% more likely than their "straight" counterparts to have recently wed or to be planning nuptials for the next year. Looking for that perfect gift for the newly wed couple? You will also get some shopping tips for identifying favored retailers of lesbian, gay and bisexual shoppers. We'll start by sizing the LGBT market. An estimated 3.7% of the non-Hispanic adult population (7.1 million adults) self-identifies as LGBT, which can be broken down as follows: The average heterosexual adult lives in a household with 1.9 other individuals, including adults and kids. By comparison, the average lesbian shares her home with only 1.6 other people. Gay men live in the smallest households, sharing their home with only one other person, on average. Over a third of gay or bisexual men (38%) share their home with at least one other adult male, compared with only 24% of heterosexual men who live under the same roof as another adult male. Thirty-five percent of gay or bisexual men say they live with one (and only one) other adult male, a living arrangement that has a higher chance of consisting of a same-sex, co-habiting couple. Over half of lesbians or bisexual women (53%) share their home with at least one other adult female, compared with only 23% of heterosexual women who live under the same roof as another adult female. Forty-three percent of lesbian or bisexual women say they live with one (and only one) other adult female, a living arrangement that has a higher chance of consisting of a same-sex, co-habiting couple. Lesbian, Gay and Bisexual adults (LGB) as a group are less than half as likely as heterosexuals to be married. Only 26% of LGB adults are wed, compared with 57% of “straight” adults. Of all LGB adults, bisexuals are the most likely group to be married, with over 4 in 10 reporting they are presently wed. Lesbians are more than four and a half times more likely than gay men to be married, with 23% of lesbians having tied the knot versus only 5% of gay men. Lesbian, gay and bisexual adults as a group are 22% more likely than heterosexual adults to have either tied the knot in the last 12 months or have plans to wed in the coming year. 5.7% of lesbian, gay or bisexual adults are newly weds or “soonly” weds vs. 4.6% of heterosexual adults. Lesbian, gay and bisexual adults are twice as likely to shop at Neiman Marcus, making the department store the number one retailer with a wedding registry program among LGB shoppers. With many retailers ending their registry programs in favor of gift cards, we looked at how stores without registry programs stack up among lesbian, gay and bisexual shoppers. LGB adults are almost twice as likely to shop at J. Crew, making the store the number one retailer without a wedding registry program among LGB shoppers.
