A business owner wants to use Google Ads to advertise their website. They're considering using one of the available Smart Bidding strategies that Google offers. Which of the following is a Smart Bidding strategy?

Target CPA (Cost Per Acquisition) is a Smart Bidding strategy designed to help advertisers get as many conversions as possible at or below a specific target cost per acquisition. It leverages machine learning to optimize bids in real time based on various signals to achieve conversion goals. Manual CPC is a manual bidding strategy, not a Smart Bidding strategy, where you set bids yourself. Viewable CPM (Cost Per Mille) is a bidding strategy focused on impressions, specifically those deemed viewable, and is not a Smart Bidding strategy for conversions. Enhanced impressions is not a recognized Google Ads bidding strategy.
