Google now lets you merge your Google+ business page with your Google+ local page. The availability to verify ownership of Google+ business page was announced August 3. With this, business owners can now become "verified" owners of the page and at the same time combine the page they have created in Google+ with the Google+ Local page (formerly Google Places listing).
"Your business’ presence across Google Search, Google Maps, and Google+ will be unified. You’ll be able to manage this page from Google+ Pages admin. Check out the Meatball Shop for an example of a combined page, with both social features and reviews."
How To Merge Google+ Business Page With Google+ Local Page
Login to your Google+, go to the page where you manage pages, and switch to your Google+ business page. From there, you'll see a link that says "Unverified" next to the title of your page. Hover over that and click the Verify now button when it appears.
Click "yes, continue to verify" to confirm your business address.
Fill out the form, as shown below; agree to terms and conditions and click to "request postcard." Your postcard should arrive within about a week.
Once the postcard arrived, go to www.google.com/local/verify, enter PIN, then clik "submit." For those who have requested a postcard for multiple Google+ business pages, you'll be able to choose the business you wish to verify when you go to the verification page.
Or you may also verify by going to your Goog+ business page, switch to use it, hover over "In Progress" link and click "enter pin."
What happens after the merge?
After the merge, you may now see the posts created with your Google+ page and the local data all on the same Google+ profile, like so.
