成效規劃工具可提供哪一方面的建議？

The Performance Planner helps you forecast how changes to your campaigns might impact performance, and it specifically recommends campaign-level Target CPA (Cost Per Acquisition) bids. This allows you to optimize your budget and bidding strategy to achieve more conversions within your spending limits. Using "Target Impression Share" as an automated bidding strategy is a valid strategy but not a primary recommendation of the Performance Planner, which focuses more on conversion-based goals for planning. Applying bid adjustments for specific regions is a granular optimization technique, but the Performance Planner provides higher-level strategic recommendations. Adding or excluding "Google Search Partners" is a campaign setting choice, not a performance planning recommendation.
