Google My Business (GMB) allows a business to register two phone numbers, which creates an excellent opportunity for Agencies to track calls generated from Google My Business listings without any risk as far as SEO (moving the business's real phone number to the secondary slot has not been found to negatively affect rankings).

When you toggle on GMB Call Tracking, the following happens: 

• If the phone number in GMB is already a Twilio number from the TekMatix sub-account, nothing will be changed as the business's calls are already being tracked in TekMatix.

• If the phone number in GMB is also the forwarding number for any of the Twilio numbers in the TekMatix sub-account, TekMatix will move the current number to the secondary slot and add the Twilio number in the primary slot. 

• If the phone number in GMB is not the forwarding number for any of the Twilio numbers in the corresponding TekMatix sub-account, TekMatix will move the current number to the secondary slot, add the Twilio number in the primary slot, and set the current number as the forwarding number for the Twilio number in the TekMatix sub-account.
