Campaign Manager 360

Industry-leading third-party ad server for enterprise advertisers and agencies, dominant within the Google Marketing Platform ecosystem

Campaign Manager 360 (CM360) is Google's enterprise ad server and campaign management platform, part of the Google Marketing Platform suite. It enables advertisers and agencies to traffic, manage, and measure digital ad campaigns across display, video, rich media, and other digital channels from a centralized interface. Originally launched as DoubleClick Campaign Manager and later rebranded following Google's acquisition of DoubleClick, CM360 has long been the industry-standard third-party ad server for large-scale advertisers. The platform provides end-to-end campaign management capabilities including ad trafficking, creative asset management, cross-channel reporting, and attribution modeling. Its Floodlight tag system is widely used for conversion tracking, and its integration with other Google Marketing Platform products — such as Display & Video 360, Search Ads 360, and Google Analytics 4 — makes it a central hub for enterprise marketing measurement and data unification. CM360 holds a dominant position in the enterprise ad serving market, particularly among large brands, media agencies, and holding companies that require robust third-party measurement independent of media buying platforms. Its deep integrations across the Google ecosystem, combined with cross-channel attribution and brand safety tools, make it a foundational layer in many enterprise AdTech stacks worldwide.
