Mastering Identity Resolution: An Introduction Guide
Unlocking the Power of Customer Data for Effective Marketing
Introduction
In today's fast-paced marketing landscape, understanding your customers is paramount. After all, how can you effectively cater to your audience if you don't even know who they are? While many platform vendors claim to provide solutions for understanding customer behavior, navigating the world of customer data technology can often be complex, filled with misinformation. Platforms such as Facebook, which has “Facebook Demographics,” and Google, which has “Google Analytics,” do serve a purpose. With that said, the platforms' tools fall short, missing critical information.
Why Understanding Your Customers Matters
Accurate customer insights are the lifeblood of brands seeking to identify their audience across various devices and channels accurately. As media continues to expand across devices and platforms, marketers face an escalating challenge. It's not just about recognizing which devices belong to a consumer but also understanding who that consumer truly is.
The Power of Identity Resolution


The answer to this challenge lies in Identity Resolution which is the art of creating a cohesive picture of individuals as they switch, and move across channels and devices, using various identifiers such as email addresses, device IDs, and home addresses. The approach you take in terms of technology partners, and what information you rely upon can significantly impact your marketing decisions. As a result, poor decisions due to lack of information can hinder your ability to increase your advertising ROI.
Navigating the World of Identity Resolution
Identity resolution may seem complex, but this is not the truth, however failure to comprehend its workings can lead to uninformed choices and costly mistakes. Here's a brief primer: Identity encompasses both offline attributes like name, address, phone numbers, and email addresses, as well as signals generated as a customer interacts online, such as cookies or mobile ad IDs. In addition, identity resolution internal third-party validators can vary greatly depending on the credibility of the third-party database partners.
Types of Identity Data
High-quality identity resolution products enable you to connect the dots between these identifiers accurately, at scale, and in compliance with privacy regulations, creating a stable and consistent customer profile. Asking the right questions about a vendor's identity resolution approach can provide clarity and confidence in the methods that can enhance your ROI.

Deterministic vs. Probabilistic Approaches
Hybrid Identity Resolution
Some vendors are now combining direct and indirect identity matrix in a hybrid approach. While this approach seems promising, its execution can be flawed if it relies on poor-quality data, inaccurate linkages, or tainted data clusters. To succeed, marketers must use raw data signals from both deterministic and probabilistic approaches to evaluate relevant linkages with high accuracy data sets.
Leveraging Identity Data
Identity data becomes valuable when activating and measuring marketing efforts. A robust identity matrix should enable precise targeting and tracking of touchpoints back to individuals or households, allowing the merging of outcome data. Strong identity resolution is crucial for customer-centric brands.
The Role of CRM Platforms

Understanding the underlying data science behind deterministic and probabilistic methods is essential. Beyond the buzzwords, marketers need to ensure that their CRM platforms can operate with granular, persistent, and accurate identities. Without the ability to serve advertising accurately across channels or track media exposures across devices, results may be inaccurate, regardless of the quality of insights, messaging, or algorithms.
Conclusion
In summary, understanding identity resolution is pivotal for any brand looking to enhance its customer-centric approach. Marketers must be discerning when it comes to identity data, going beyond buzzwords to ensure their marketing platforms operate at the highest levels of accuracy and granularity. Because without the ability to identify and serve the right consumers across various channels, results will fall short of expectations.
