Design and Implementation of Tag Systems in Customer Data Platforms

The presentation introduces the fundamentals of tags and tag systems, emphasizing their role as the foundation of digital marketing by abstracting business object features and supporting various business scenarios.

It outlines the core design considerations for a tag system, including traceability, real‑time vs. offline computation, flexibility in rule configuration, and strong management of permissions, APIs, and Kafka subscriptions.

The construction workflow follows a standard 5W2H methodology—defining what, where, when, why, who, how, and how much—starting from business requirements, data ingestion (behavior, attribute, and business data), ETL processing, ID unification, and finally tag generation and usage.

Tag creation methods in the VeCDP platform include rule‑based tags, lifecycle tags, first/last‑event tags, and preference tags, with configurable update frequencies (real‑time or scheduled).

Typical industry case studies demonstrate how automotive, retail, and financial sectors design customized tag hierarchies to support customer lifecycle management, precise audience segmentation, and risk/value assessment.

The Q&A section addresses practical concerns such as scoring mechanisms, integration with marketing automation (MA) tools, rapid tag creation, quality assurance, underlying storage technology (ClickHouse), and strategies for maintaining tag consistency across teams.

Overall, the talk provides a comprehensive view of building, evaluating, and leveraging a robust tag ecosystem to drive data‑driven marketing and operational insights.
