| Fields ||

| ## `bid_only` | `bool` Indicates whether to restrict your ads to show only for the criteria you have selected for this targeting_dimension, or to target all values for this targeting_dimension and show ads based on your targeting in other TargetingDimensions. A value of `true` means that these criteria will only apply bid modifiers, and not affect targeting. A value of `false` means that these criteria will restrict targeting as well as applying bid modifiers. |
