In the ancient years of Google Places, we weren’t able to transfer business listings from one account to another easily. And, we weren’t able to assign additional people to a listing (i.e. managers, staff, etc). Now with Google My Business, we can assign managers and transfer full ownership of a listing from one account to another. Of course, if you want a listing to be fully transferred, you have to first assign the new account Manager access and wait 2 weeks before you can grant the full Owner access.
It’s not everyday that I work on migrating a large set of Google+ Pages from one account to another. But, in case you’re helping your client with that, just keep in mind that there is a daily maximum of 21 Google+ Pages that can be transferred, at least this is where Google stopped me from assigning a new Manager to listings.
I also noticed there is no mention of a maximum on Google’s support page so I’m just pointing it out here in case anyone is disappointed as I am that I have to go through this process of inviting the new account and accepting those invitations, one at a time. Doing it for 89 pages right now, and I’m about 23% through 🙂 Yay!.
