This document discusses the process of "onboarding", which allows advertisers to merge customer relationship management (CRM) data with online consumer data for advertising purposes, without violating privacy laws. It involves transferring CRM data to a third party, which then anonymously links the CRM data to browser data using algorithms and secure systems. The author argues that onboarding is an important development for the real-time bidding, demand-side platform, and data management platform industries in China, as it allows advertisers to safely integrate different data sources. Onboarding provides a way to leverage valuable CRM information while avoiding legal issues around using personally identifiable information for online advertising.
