Hey all, hoping for some insight!

Have a friend who has a Service Area Business in the seasonal northeast. He wants to optimize his site/GMB for the northeast location during the spring/summer. Then during the fall/winter he is going to be working in Florida. The same business, same services, just different location. He asked me if he could optimize one site/GMB for both or if he would have to have to make a separate site/GMB. TIA! Any help would be greatly appreciated!!
