Google My Business has added a new option that says “Connect in real-time, with video.” It says you can “grow your business and reach more customers when you use video conferencing providers.” Then a “set up” button to start to configure it.
I suspect this is activated after you update your service availability to specify you offer video appointments but I am not 100% sure.
Here is a screenshot of the box on the main home dashboard of Google My Business after you sign in and select a specific business:
After you click on “Set up” you are given these online video service providers including Google Meet, Webex, Skype and Zoom. Here is a screenshot:
But after that, there does not seem to be a way to set it up more beyond that yet. When you click on Google Meet, it takes you to google.com/meet. In fact, all the links take you to those service providers.
Google does link to this help document with more details on how to configure it.
A lot of the local SEOs are chatting about this as well in the Local Search Forums.
