This is really simple you do not need a lengthy tutorial..
step 1) go to http://www.google.com/places/
step 2) click on the get started
step 3) create a google account with your work email
basic q & a
q) do i need a gmail account for this?
a) no you do not need a gmail account but if you already have a gmail account you will automatically have a google account.
(personal preference create a new google account with your work email that you use as a main contact ex. email@example.com as the username and remember your google password)
step 4) verify your new google account by checking your emails.. then log in
(note while logged in you will see in the upper right hand side your email as logged in)
step 5) click on the list your business
step 6) enter your phone number and click find business information
step 7) google will either find your business or not if it doesn’t enter in all the details and you will get a card in the mail to verify.. since we are already assuming google has your map listing and we are claiming ownership instead of creating a new business we will continue with how to claim ownership.
step 8) enter in all the key information don’t worry about videos or pictures for now you can modify them after you own it at this point just add your store hours and most importantly your website. then click on submit.
step 9) at this point google will ask you how you would like to verify ownership phone call or postcard in the mail. a phone call is the fastest and most sought out method so make sure your business phone is in your hand when you verify by phone…. google calls right away.. there is a 6 digit pin you enter under the verification box and your done.
q) i am not getting the phone option did i do something wrong?
a)it appears if someone else tried to claim your listing or if you are in another state or country or if it is a brand new business google prefers to play it safe and verify by mail your listing .. original mail from google looked like post cards and nwo they recently were replaced with actual letters. either way KEEP AN EYE OUT FOR THE colored GOOGLE LOGO. mailing time is aprox. 5 days to 15 days depending on location.
