Performance Max
lets you access all Google Ads channels and inventory from a single unified campaign. It helps you optimize performance and work more efficiently, in part by reducing the complexity and overhead needed to manage multiple campaign types.
Performance Max campaigns allocate budgets dynamically to the highest-performing channels, including Search, YouTube, Display, Discover, Gmail, and Maps. This helps you get more conversions at the strongest ROI from your budget, and also eliminates the need for you to manage and update budgets across several campaigns.
