As of now, we don't set up a conversion tracker for Search campaigns but only Shopping campaigns.
If you already have a conversion tracker in place, it will also cover the conversions from your Cobiro campaigns based on the actions you have defined as conversions.
If you don't have a conversion tracker implemented but you want to track and measure your conversions, you need to manually set up a conversion tracking in Google Ads (formerly Google AdWords). It is up to you to decide which customer actions you define as a conversion and want to track.
