Google Ads API v25.1 adds 24 lift metrics for measurement parity
Google has released version 25.1 of the Google Ads API, which introduces 24 new conversion lift metrics, brand sentiment insights, and loyalty tier segmentation. While the update provides programmatic access to previously siloed measurement data, several key features remain restricted to allowlisted accounts.
Key Takeaways
- New read-only resources LiftMeasurementConfig and LiftMeasurementFlight expose study dates and conversion goals
- BenchmarksService gains a category_filter to scope competitive performance data against specific product categories
- Loyalty membership tiers are now available as a reporting segment and a conversion value rule dimension
- Metrics.original_conversion_value surfaces unadjusted data nine months after its debut in the Google Ads interface
- ReachPlanService adds parental status targeting, though access requires a Basic level developer token or higher
Why It Matters
The inclusion of lift measurement metadata allows engineers to programmatically join causal contribution data with marketing mix models and data warehouses. By moving statistical winner scores and flight details into the API, Google is reducing the manual export burden for agencies managing high-volume incrementality experiments. This shift reflects a broader industry trend toward transparent, queryable measurement as advertisers demand more granular proof of performance across fragmented video surfaces. Watch for whether Google eventually moves these lift resources from allowlist-only to general availability for self-serve developers.
Additional Context
As brands seek digital-level measurement precision across all channels, the ability to automate data ingestion becomes a critical competitive advantage for programmatic automation within ad tech stacks.
