The Performance Planner helps you forecast campaign performance and suggests campaign-level Target CPA (Cost Per Acquisition) to achieve your marketing goals. It focuses on budget and bidding strategies to maximize conversions within your spend. While bid adjustments, bidding strategies like Target Impression Share, and network settings are important for campaign optimization, the Performance Planner's core function is to provide overarching budget and CPA recommendations for entire campaigns, not granular settings for specific locations or network partners.
