Well what you want is a Places page. Here’s a crash course:
First you need a google account. If you have a gmail address, that’s your google account (and your email/password for gmail is your google account credentials for all google products).
So if you’re signed in to google, first do a search for your business, and click on the Maps tab at the top . If you see the listing for your company in the Maps results page, click on it. (if you don’t see your company there, skip down to the “If you don’t see it” part below.)
Up in the top right corner, click on the “Business Owner?” link. From there you’ll pick the “Edit my business information”. At that point, you can edit the page, add or remove information, almost like a facebook profile. You can also then take ownership of the page so no one else can edit it, and you’ll have instant access to it. But before you finish up the profile and take it over, Google will require that you verify you really own the business. It’s explained well enough when you get to that point, I won’t do into it here or you can PM me for more info.
Anyway, if you don’t see your listing when you Google your biz, click on your name in the top right corner of the window. Click “Account Settings”, then Products in the left pane. You should see a Google Places button on the page, click it. (or you can go to google.com/places/. On the right, click the big blue button that says Get Started, under “Claim your business listing on Google”.
Follow the steps and use any help resources you need along the way and make sure to create a robust profile with every option utilized. Again, you’ll be required to verify your business ownership before it’s published on Google.
Good luck, update us with a link to check out your new page when it’s done!
