If you want to manage frequency within your Programmatic Guaranteed deals across multiple publishers, at what level should this be configured in your Display & Video 360 account settings?

Frequency capping for Programmatic Guaranteed (PG) deals across multiple publishers is configured at the campaign level. This allows you to set a unified frequency cap that applies to all PG line items within that campaign, ensuring a consistent user experience and preventing overexposure across different publishers participating in your PG deals. Setting it at the line item level would only control frequency for that specific line item, not across multiple publishers. The insertion order level is too broad for managing specific PG deal frequency across publishers, as an insertion order can contain various line item types. The advertiser level is too high and would apply to all campaigns, which might not be desirable for specific PG strategies.
