The core benefit of Google Ads automated bidding is Auction-time bidding.

Here's why:

1. User ID-based bidding: This is not a feature of Google Ads automated bidding. User ID-based bidding would imply targeting specific users, which is not how Google Ads operates.

2. Impression share-based bidding: While you can set strategies based on impression share in Google Ads, it's not a core benefit of automated bidding. Impression share-based bidding is more about visibility and doesn't necessarily optimize for conversions or clicks.

3. Daily budget pacing: This is a feature of Google Ads, but it's not a core benefit of automated bidding. Daily budget pacing allows you to spread out your ad spend over the course of a day, but it doesn't optimize your bids in real-time.

4. Auction-time bidding: This is a core benefit of Google Ads automated bidding. Auction-time bidding allows Google's machine learning algorithms to analyze a large number of signals at the time of each auction and set the optimal bid. This can lead to better performance of your ads and is a unique advantage of using automated bidding.
