Let’s have a look at the initial page creation form, which asks for basic information such as a brand name and a URL:
At first, whoever creates the page initially will also be the page administrator. No one else will be able to admin that page after them, at first. Nor can that page be transferred to someone else.
Multiple administrator support is promised in the near future, but until it arrives, it seems important that if your company has a social media manager, that person should be the one to create the account.
Unlike Facebook, there aren’t “vanity” URLs yet available that use a business name rather than a long string of number. The same issue is true of personal accounts. Google provided no update on when this might change.
