How does "Enhanced Conversions for Web" improve conversion measurement accuracy while ensuring privacy safety?

Enhanced Conversions for Web enhances measurement accuracy by supplementing existing conversion data with first-party customer information. This data is:
  1. Hashed using SHA256 encryption before being sent to Google, ensuring privacy protection.
  2. Matched securely with signed-in Google accounts to attribute conversions accurately to ad interactions (clicks, video views, etc.).
  3. Useful in cookieless environments, helping advertisers track conversions even when third-party cookies or tracking restrictions limit traditional methods.
By following privacy-compliant hashing and secure data transmission, Google ensures that advertisers get better attribution insights while keeping user data protected.
