小马听说应当每月使用一次效果规划工具。 她为什么应当这样做？

The Performance Planner helps advertisers anticipate how changes in external factors, such as seasonality, market trends, and competitor activity, can impact campaign performance. By using it monthly, advertisers like Pony can proactively adjust their budgets and bids to optimize for these shifts, ensuring their campaigns remain effective and achieve their goals. "To view new keyword optimization suggestions" is incorrect because the Performance Planner focuses on budget and bid forecasting, not keyword suggestions. "To check for status issues" is incorrect as campaign status issues are typically monitored in the Google Ads interface, not the Performance Planner. "To analyze demographic targeting performance" is also incorrect; while demographic data is considered, the Planner's primary function is forecasting overall campaign performance based on budget and bid adjustments, not a deep dive into demographic segment performance.
