Google has introduced an updated GenerateKeywordForecastMetrics method in Google Ads API v24 to create a more streamlined experience for advertisers. The update refines forecasting by focusing on metrics that directly affect performance based on selected bidding strategies.

Key updates include:
- Alignment with Bidding Strategies: Forecasts focus solely on metrics impacting chosen strategies, such as conversions and costs.
- Streamlined Request Parameters: Changes simplify requests and improve reliability, removing less impactful fields from the forecasting process.
The new API version is available from April 2026, with the previous version scheduled to sunset in February 2027. Developers using this feature should review their integrations to ensure compatibility.
