In episode 259 of Semantic Mastery's weekly Hump Day Hangouts, one participant asked if PO Box is better than a temporary office.
The exact question was:
I had a temp office address for our business. I don't know if someone brought it to google's attention but they canned it with all of the reviews, seo work etc. I now have set up a new one from their home address which i verified but it just is sitting there waiting on review. I saw your post somewhere recently where you liked the pobox better than the temp office. Is there anything to do to move them along from pending? thanks
