Here is a lovely tip to quickly find the businesses with pages set up already on Google Maps.
This then allows you to click into a listing and then see if a page has been claimed, or not.
Note: If it has not been claimed you will see a +1 button and not a follow button, and the option to claim it.
Start with looking at ‘Local’ and then search for the place in your Local area.
