The digital advertising landscape has undergone a seismic shift in recent years. Privacy-conscious consumers, transformative regulations, and emerging technologies are converging to redefine how addressability — the ability to accurately reach a specific audience — functions in this new era. Addressability is a cornerstone of digital advertising, and its evolution presents both challenges and opportunities for publishers and advertisers alike.
The need for enhancing addressability is driven by a complex set of factors. More consumers are opting out of data sharing or disabling cookie-tracking, leading to a drastic reduction in the reach of traditional programmatic advertising. Nearly 70 percent of consumers are now unreachable through these conventional methods, creating an ‘addressability gap’ that publishers and advertisers are eager to bridge. The landscape is further complicated by privacy regulations such as General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), which mandate solutions that balance user privacy with advertisers’ needs.
Contributing to this intricate mix is the growing shift toward video and connected TV (CTV). These platforms have long operated in a cookie-less environment and are witnessing rising demand due to their engaging nature and broad reach. However, the attractiveness of these mediums to advertisers hinges on effective addressability, highlighting the urgent need for innovative audience identification and targeting methods.
The emergence of data enablers and collaborative initiatives
Data enablers like Experian are stepping up to meet this need. These companies are providing robust, privacy-compliant data resources to improve addressability. Experian’s unique approach to identification, the Living Unit ID (LUID), is a key tool in bridging the current gap in reach.
How Experian and Microsoft Advertising are redefining addressability
We recently expanded our collaboration with Microsoft, to make our extensive data resources available through Microsoft Advertising’s data marketplace. This collaborative initiative represents a significant move, offering a compelling model of how data enablers and buy-side and sell-side platforms can work together to redefine addressability.
The benefits of this arrangement extend to all stakeholders in the ecosystem. Advertisers using Microsoft Invest can now access Experian’s audience data. This not only enhances the granularity of their audience targeting but also broadens the reach of their campaigns. Experian’s identity spine also serves as a robust framework to extend the value and reach of advertisers’ first-party data.
For publishers, the accessibility of Experian data on Microsoft Advertising’s data marketplace opens the door to greater addressability in their inventory, enabling them to offer advertisers more addressable impressions. This then amplifies the value of their inventory, potentially increasing their overall yield. For advertisers, this integration facilitates access to highly relevant audiences while simplifying campaign setup and respecting user privacy.
We can help you carve a new path toward addressability
In the ever-evolving landscape of digital advertising, such collaborative efforts are becoming critical to ensure that advertising remains effective for brands, profitable for publishers, and respectful of consumer privacy. This model of cooperation and innovation is essential to navigate the challenges of a privacy-centric, cookie-less world and unlock the true potential of every media channel.
With collaborative initiatives and innovative solutions, the industry is set to transform these challenges into opportunities, carving a new path toward addressability that respects privacy and delivers value for all stakeholders.

We all knew heading into the holiday season that consumers were going to be highly sensitive to price due to the economic conditions, paving the way for an increase in online deal seeking. Coupon websites experienced growth in visits throughout the holiday season as shoppers searched for promotional codes to use online and printable coupons for offline purchases. The weekly market share of visits to coupon websites increased 15% from the previous year during the week of Thanksgiving & Black Friday and also increased 16% during the week of Cyber Monday. Overall, visits to the custom category of 70 websites increased 17% and 12%, in November and December, respectively, as compared to the previous year. Coupon website referred traffic to retailers relies upon the availability of promotional codes and coupons for a given retailer. The availability of coupons and desired savings can certainly help to finalize and capture the transaction, making participation with coupon websites beneficial to the majority of retailers – particularly as many offer discounts & promotions during the holiday season and consumers inevitably share them anyway. In December 2008, the most commonly visited product categories following a visit to a website within the coupon category were department stores, computers, and appliances & electronics. One interesting point is that many shoppers are looking for coupons from a specific retailer or brand, suggesting that many coupon searchers may be further along in the purchasing funnel and are close to making the purchase – but may need some type of final incentive. For the week ending December 27, 2008, 69% of the searches for the top 300 search terms that include ‘coupons’ also included a specific brand such as Pizza Hut, JCPenney, or Target. The other 31% of searches to include the term ‘coupons’ were generic in nature, seeking out grocery coupons, online coupons, and free printable coupons.
