I am wondering about virtual mailbox and PO Box implications for Google. My understanding is that PO Boxes are not so good for google rankings - is that correct? Virtual mailboxes seem to require filing of an "Application for Delivery of Mail Through Agent", form USPS 1583. This is different than a change of address - s there any way Google knows this, or is it just simply whatever address you indicate on you website, your citations and your GMB account? And with regard to changing the address on citations, is there a product that can be used to avoid the agony of changing address for all those citations by hand?
