Data Manager expanded into Google Analytics and DV360 with a universal API and built-in diagnostics

Google built Data Manager directly into Google Analytics and Display & Video 360 so first-party data connections can be managed across platforms from one place. The Data Manager API became universal and is now based on IAB Tech Lab standards, and Data Manager gained built-in diagnostics that identify and resolve data issues before they affect campaign performance.

Enhanced conversions is included in the expanded surface for secure customer-data matching. The move continues the consolidation that pulled store sales measurement into Data Manager on September 8 and added a data source diagnostics hub in February 2026; the diagnostics here are described as automatic rather than a view an advertiser has to check.
