如果您想结合所有非关键字 Google 广告，形成一种自动化的跨产品的广告系列类型，您会使用下面哪一种广告系列类型？

Performance Max campaigns are designed to combine all non-keyword Google Ads into a single, automated, cross-product campaign type. They leverage advanced automation across bidding, targeting, creatives, and attribution to help advertisers drive more conversions and conversion value. Smart Shopping campaigns are specifically for e-commerce revenue growth based on ROAS goals, not all non-keyword ad types. Call-to-action video campaigns focus on YouTube conversions. App campaigns are tailored for app downloads and in-app actions. Therefore, Performance Max is the correct choice for a comprehensive, automated, cross-product approach to non-keyword Google Ads.
