Campaign Manager 360

One of the most widely used enterprise third-party ad servers globally, deeply integrated within the Google Marketing Platform ecosystem

Campaign Manager 360 (CM360) is Google's enterprise ad serving and campaign management platform, part of the Google Marketing Platform suite. It enables advertisers and agencies to traffic, track, target, and measure digital advertising campaigns across display, video, rich media, and other digital channels from a centralized hub. Originally launched as DoubleClick Campaign Manager and later rebranded following Google's acquisition of DoubleClick, CM360 has evolved into one of the most widely adopted third-party ad servers in the industry. The platform provides end-to-end campaign management capabilities including ad trafficking, creative management, audience targeting, cross-channel attribution, and detailed reporting. Its Floodlight activity tracking system allows advertisers to measure conversions and site activity, while its integration with other Google Marketing Platform tools — such as Display & Video 360, Search Ads 360, and Google Analytics 4 — enables a unified view of campaign performance. CM360 supports a wide range of ad formats and serves as a neutral measurement layer for advertisers running campaigns across multiple media buying platforms. CM360 occupies a dominant position in the enterprise ad serving market, competing primarily with other third-party ad servers. Its deep integration with the broader Google ecosystem, robust reporting infrastructure, and cross-channel measurement capabilities make it a preferred choice for large advertisers, global brands, and full-service agencies managing complex, multi-channel digital advertising programs. The platform is offered as a managed service with pricing typically based on impressions served.
