Which statement accurately describes Performance Max campaigns?

Performance Max campaigns are designed to give advertisers a holistic approach to reach their audiences across various Google platforms. This means that these campaigns enable advertisers to access audiences through multiple channels, including YouTube, Display, Search, and Gmail, all within a single campaign structure.

The effectiveness of Performance Max lies in its ability to utilize inventory and placements across these platforms, thereby optimizing performance based on the goals set by the advertiser. This integrated model helps to streamline campaign management and improves reach, allowing advertisers to effectively communicate with potential customers wherever they may be online.

In contrast, other options imply limitations or requirements that don't align with the functionalities of Performance Max. For example, requiring different campaigns for every channel contradicts the integrated nature of Performance Max campaigns, which are specifically designed to operate across channels without the need for separate campaigns.
