At an advertising agency, you add several clients to your portfolio but they’re across different categories.What’s the correct way to structure the Campaign Manager 360 instances to make sure transferability is easy?

The correct approach is to create an agency account and then add each client as a separate "Advertiser" within that single agency account. This structure is designed for agencies managing multiple clients. It allows for easy transferability of assets, reporting, and user management across all clients under one umbrella. Creating separate networks for each client is incorrect because networks are typically used for distinct organizations or large divisions, not individual clients within an agency. Creating multiple campaigns for each account or client is a standard practice for organizing ad efforts, but it doesn't address the overarching structure for managing multiple clients efficiently at the agency level. The "Advertiser" level is specifically designed for client separation within an agency account.
