Using enhanced conversions requires which of the following circumstances?

Enhanced conversions build upon your existing Google Ads conversion tracking. They allow you to send hashed first-party customer data from your website to Google in a privacy-safe way, improving the accuracy of your conversion measurement. This data is then matched against Google's logged-in user data to attribute conversions more precisely. Therefore, having Google Ads Conversion tracking implemented is a prerequisite. While email addresses and mobile numbers are used with enhanced conversions, they are not the requirement for using the feature itself; the requirement is the underlying Google Ads Conversion tracking. Enhanced conversions are not tied to specific buy-side platforms like Google Display Ads or DV360, nor are they limited to Google Analytics or offline conversions as the primary source; they specifically enhance Google Ads conversions.
