GMB is showing as a source in Google Ads call details report. Why?

[dotgal]

I ran a Calls Detail report and see now that GMB is now a call source. My initial thought is that calls via GMB are free. Could someone explain to me where the "Google Ads" are showing up on GMB? Or is this a label change on Google Ads' end and it was formerly known as "Ads" under call source?

If you have location extensions enabled, that would be you're seeing it there. Location Extensions cause your GMB listing to show as part of your ad.
