What are enhanced conversions in Google Ads?
Enhanced conversions send hashed first-party data such as email address and phone number with a conversion so Google can match conversions it would otherwise miss after cookie loss. Enhanced conversions typically recover 5 to 15% of unattributed conversions and improve smart bidding accuracy, especially for lead generation accounts using offline imports.
