Generate a Reach Curve

Important: This feature is available to allowlisted accounts only. Contact your Google representative if you need access to the feature.

Once you've gathered the targeting settings and a product mix for your media plan, you can generate a curve of budgets versus potential reach using the GenerateReachForecast method in ReachPlanService. See the glossary and media plan guide for details on the request fields.

Note: Within the GenerateReachForecastRequest.Targeting.AudienceTargeting object, certain user_interest_category values in UserInterestInfo are not supported for reach forecasts.

Save curves

You can only save individual curves to provide convenience for your users. Caching curves en masse is strictly prohibited. If you do need to generate curves en masse, check first with your Google representative.

Changes for YouTube Select

YouTube Select (YTS) in Reach Plan Service now supports lineup-level targeting, as compared to Run-of-Network previously, for all eligible YTS locations on Instant Reserve pricing. With Instant Reserve, these errors may also occur when requesting a forecast for YTS:

1. Not enough inventory available
2. Non-spending accounts disabled

Forecast reach for Demand Gen

When generating curves for DEMAND_GEN plannable products, you must also include an expected conversion rate for each product.

To obtain conversion rate suggestions for supported plannable products, use the GenerateConversionRates method.

Code example

The curve includes impression and user reach in absolute numbers, as well as universe sizes corresponding to the census population and YouTube audience size for the requested demographic and country.
