Google is rolling out significant updates across DV360, Campaign Manager 360, and Search Ads 360 this summer.
These changes will impact reporting, API usage, and how advertisers structure their campaigns and measurement.
Deprecations
– Removal of Nielsen-related auto-tagging metrics (feature already deprecated in 2021)
– YouTube Audience Attribute (YTAA) metrics and dimensions will be removed
Cross Campaign Optimization (CCO) ends September 1, 2025, Programmatic – Guaranteed deals must be isolated to single line items
Label and ID Updates
– Adloox is rebranded to Scope3 throughout UI, API, and reporting
– Several YouTube dimensions in reports will now be labeled more clearly (e.g., “Gender (YouTube)”)
– ID space and criterion ID updates for device, ISP, browser fields (important for Data Transfer v2.0 users)
Reporting Enhancements
– YouTube reports will now align to a Monday–Sunday weekly format
– The “Country” dimension is being removed from reach reports for more flexible segmentation
– Frequency reports gain new 8+ and 9+ impression buckets
– Floodlight activities will support the Category field for improved reporting structure and consistency across platforms
– Improved logic in Unique Reach and Cross-Media Reach reports for more accurate overlap data
Conversion API Upgrade
– A new session_attributes parameter is being introduced to Campaign Manager 360 and Search Ads 360 offline conversion APIs
– This is especially useful when GCLIDs or DCLIDs are unavailable and supports better measurement and bidding accuracy
Most changes will be rolled out between July and September 2025.
