Enhanced Conversion
Enhanced conversion is an advanced tracking functionality that helps more accurately measure conversions, even if cookies or other ways of tracking are restricted by privacy options. By hashing client data that was collected during conversion, for example email address, phone number or home address, and sending it to Google’s servers securely, Google can infer the user without breaching any privacy laws. Google then uses this data to match a single conversion to the user that interacted with your advertisement.
