If a business deals with clients directly and is something that existing and prospective clients would search for then it would be a likely candidate to have a tour done. There are some current restrictions imposed by Google, however, which are that no Legal or Government Offices can be done at this time. In addition, businesses that violate the terms of service for the Google Business Photos (Nudity, drugs and drug paraphernalia, etc) are ineligible.
This is an ideal opportunity for restaurants, coffee shops, retail stores, car dealerships, Spa’s, Hair Salons and any independent small business owner to showcase their businesses.
