Use Search Ads 360 conversion data with Google Ads auction-time bidding
To enhance your Google Ads campaign performance, you can use Search Ads 360 conversion data with Google Ads auction-time bidding. Because auction-time bidding is available only in Google Ads, you’re required to share Search Ads 360 conversion data with Google Ads and replace Google Ads conversion data with Search Ads 360 conversion data to enable this feature.

When you enable conversion sharing in a Search Ads 360 sub-manager account, you can choose to use Search Ads 360 goals for optimization. The setting replaces the Google Ads conversion data in the ”Client account conversions” column with Search Ads 360 conversion data so that both columns then contain the same value.
