Google Ads auction-time bidding is different from Search Ads 360 intra day bidding in which of the following ways?

Google Ads auction-time bidding optimizes bids in real-time for each individual auction, leveraging machine learning to consider numerous signals at the moment of the auction. This allows for highly granular bid adjustments based on the specific context of each search query. In contrast, Search Ads 360 intra-day bidding adjusts bids several times throughout the day based on performance data and predefined rules, but it does not bid in real-time for every single auction. It operates on a more scheduled optimization approach rather than per-auction optimization. The first option is incorrect because both systems can incorporate device, location, and bid adjustments, but their timing and methodology differ. The second option reverses the correct distinction between real-time optimization and several-times-a-day adjustments. The third option is incorrect because Google Ads auction-time bidding is specific to Google Ads, not portfolio strategies across multiple engines, and it is Search Ads 360 that offers cross-engine capabilities.
