Google Ads Call Assets QR Codes Or Send Email Are Tracked
Briefly

Google Ads allows tracking of conversions from QR codes and actions like sending emails or making calls. Through call assets in ads, users can access phone numbers via clickable buttons. On mobile devices, scanning a QR code opens a phone dialer with the number pre-filled. For desktop devices, a 'Call us' button displays the number. Call reporting features track these interactions, confirming that these actions can be monitored within Google Ads.
Conversions from scan or send to email actions are tracked and reported.
When your call assets appear with your ad, people have access to your number, with clickable call buttons on mobile and desktop.
