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 have 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.

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

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.
