Frequently Asked Questions
What is Cross-Device Identity Resolution?
Cross-Device Identity Resolution is the process of identifying and linking a single user's activity across multiple devices, such as smartphones, tablets, and desktop computers. Its primary goal is to create a unified, persistent profile of the customer, which is essential for accurate multi-touch attribution and personalized marketing. This process uses a combination of deterministic and probabilistic matching methods. Deterministic matching relies on personally identifiable information (PII) like email addresses or login IDs, which provide a high degree of accuracy. Probabilistic matching uses non-PII data, such as IP addresses, device types, and behavioral patterns, to infer a match with a lower but still useful degree of certainty. This unified view is critical for marketers to understand the complete customer journey and optimize their ad spend in a privacy-first world.
How can marketers implement Cross-Device Identity Resolution for better attribution?
Marketers can implement Cross-Device Identity Resolution by leveraging an Identity Graph, which is a database that maps various identifiers (like cookies, device IDs, and PII) to a single user profile. The first step is to collect first-party data, such as customer login information, which forms the foundation for deterministic matching. Next, they should integrate with a Customer Data Platform (CDP) or a specialized identity resolution vendor that can ingest this data and apply matching algorithms. This unified data is then used to power multi-touch attribution models, ensuring that credit for a conversion is accurately distributed across all touchpoints, regardless of the device used. This approach provides a more accurate return on ad spend (ROAS) and allows for more effective budget allocation across channels.
What is the difference between Cross-Device Identity Resolution and Cross-Device Attribution?
Cross-Device Identity Resolution is the foundational technology, while Cross-Device Attribution is the application of that technology. Identity Resolution is the process of linking a user's various devices and touchpoints to a single profile, essentially answering the question, 'Is this the same person?' It creates the unified customer view. Cross-Device Attribution, on the other hand, is the process of assigning credit to the marketing touchpoints within that unified customer journey, answering the question, 'Which touchpoints led to the conversion?' Without accurate Identity Resolution, Cross-Device Attribution is impossible, as the system cannot accurately track the user's journey across different screens. Therefore, Identity Resolution is the prerequisite for achieving accurate, person-centric attribution.
