A manager at an advertising agency works with several clients across different categories.How should they organize their Campaign Manager 360 instance(s) to make certain transferability is simple?

The most efficient and scalable way to manage multiple clients in Campaign Manager 360 is to create a single agency account and then set up each client as a separate "Advertiser" within that agency account. This structure allows for easy transferability of floodlight configurations, user roles, and reporting across clients, while maintaining distinct data for each. Creating several networks (one for each client) is unnecessary and complicates management, as networks are typically used for entirely separate business entities or large organizational divisions. Creating many campaigns for each account or several campaigns for each client doesn't address the fundamental organizational structure at the advertiser level, which is key for transferability and overall account management.
