每天在 Google 上发生的搜索高达数十亿次，Google AI 如何帮助营销者尽可能提高搜索广告效果？

The correct answer is that Google AI helps maximize Search ad performance through broad match and Smart Bidding, which match ads to queries and adjust bids in real time. Broad match uses AI to understand the intent behind searches, even if the exact keywords aren't present, expanding reach. Smart Bidding leverages AI to analyze vast amounts of data signals in real time to optimize bids for conversions or conversion value, aligning with campaign goals. The other options are incorrect because: Smart Bidding predicts conversion likelihood, not "highest traffic queries," to set bids. Ad Rank prioritizes expected CTR, ad relevance, and landing page experience, but it's not solely about prioritizing these; it's a calculation that includes bid, context, and ad extensions. Google AI does not eliminate the need for high-quality image assets; strong creative remains crucial for ad performance.
