Google Ads API v25.1 adds lift measurement and migration fields
Google released the non-breaking v25.1 update with support for Brand Lift and Conversion Lift resources, new AI Max migration date fields, text-disclaimer assets, benchmark services, loyalty segmentation, and additional reporting dimensions. Client libraries must be upgraded before the new capabilities can be used.
This update uses a PMC cover because no suitable source image was available when checked on 8 Sept 2026. Available source and video links are retained.
Why it matters for advertisers
For you, this means API teams can prepare for Search migrations and richer lift reporting without a major-version rewrite, but should still test field dependencies before deployment.
