为了利用广泛匹配扩大覆盖面，您可以遵循哪三项最佳实践？

To expand reach with broad match, leveraging responsive search ads and AI-powered creatives is crucial because they dynamically adapt ad content to various search queries, maximizing relevance and engagement. Organizing all ad groups around a common theme ensures that broad match keywords trigger relevant ads, improving ad quality and performance. For brand campaigns, combining broad match with brand restrictions helps capture a wider range of brand-related searches while maintaining brand safety and control. Using manual bidding with broad match is generally not recommended as automated bidding strategies are more effective at optimizing for reach and performance, especially with broad match. Adding broad match keywords to existing exact match keywords in various campaigns is a good strategy, but the option specifies "across various campaigns," which is less precise than organizing by theme for optimal management.
