| Fields ||
|---|---|
| ## `app_installs` | `double` Projected number of app installs. |
| ## `biddable_conversions` | `double` Projected number of biddable conversions. |
| ## `biddable_conversions_value` | `double` Projected total value of biddable conversions. |
| ## `clicks` | `int64` Projected number of clicks. |
| ## `cost_micros` | `int64` Projected cost in micros. |
| ## `impressions` | `int64` Projected number of impressions. |
| ## `in_app_actions` | `double` Projected number of in-app actions. |
| ## `interactions` | `int64` Projected number of interactions. Only discovery advertising channel type supports this field. |
| ## `required_budget_amount_micros` | `int64` Projected required daily budget that the advertiser must set in order to receive the estimated traffic, in micros of advertiser currency. |
| ## `target_cpa_simulation_key_value` Union field. When SimulationModificationMethod = UNIFORM or DEFAULT, target_cpa_micros is set. When SimulationModificationMethod = SCALING, target_cpa_scaling_modifier is set. `target_cpa_simulation_key_value` can be only one of the following: ||
| ### `target_cpa_micros` | `int64` The simulated target CPA upon which projected metrics are based. |
| ### `target_cpa_scaling_modifier` | `double` The simulated scaling modifier upon which projected metrics are based. All CPA targets relevant to the simulated entity are scaled by this modifier. |
| ## `top_slot_impressions` | `int64` Projected number of top slot impressions. Only search advertising channel type supports this field. |
