What Is Google MCM?
Multiple Customer Management (MCM) is a premium (and paid) feature within Google Ad Manager 360 that allows certified partners monetize publisher's inventory. In other words, instead of working directly with Google Ad Exchange, publishers connect through an MCM parent partner.
This creates two roles:
Parent Partner
Has direct access to Google AdX
Manages monetization
Optimizes demand and pricing
Child Publisher
Owns the website
Grants inventory access
Receives revenue share
This model replaced Google's older SPM (Scaled Partner Management) program and introduced better transparency, control, and flexibility.
