Google My Business recently added a new option to track calls from your GMB profile if their phone number shows to viewers. You can see recent, missed calls, and more!

This GMB function uses a call forwarding number. When the business receives a call from this system, they will hear the message “Call from Google” to identify when the call is via their profile or other source.

You need to turn on this tracking. From the main page for the company profile in Google My Business Dashboard, click “Calls” at the left navigation pane. Next, select “Turn on”.

The GMB phone call tracking will begin from that moment forward!
