We recently had a Service Area Business come on with us as a client. The have four locations over two states. They should all be able to get verification postcards etc. My question is should we stagger the set up of their GBP's in order to minimize possible ramification on Google's end or set them all up at once? I realize it is a bit of a gray area we are working in too. Any advice on how to best go about it would be appreciated. Thanks!
