Welcome to the Q&A Forum

Do you have a version of each page. www.example.com/page & www.example.com/page?   ?   Then yes this is duplicate content.

Do you have a link back to your Google+ listing from your website? Try putting a link in your footer to the page & on your Contact Us page as well. You want to try and marry the listing to your site.

Has anyone heard anything about this Google warning that was supposedly sent to some Google Place owners recently.

The message says:

We are making some changes to Google Places for Business and Google Maps so we can continue providing people with the best experience when they're looking for local businesses. As part of this process, we're asking business owners to review and confirm some of the information in their Google Places accounts so we can keep showing it to Google users. We know this will be a few extra steps for merchants, and we apologize for any inconvenience and thank you for your time.

We have sent business owners affected by these changes an email entitled "Action Required: You have 3 weeks to save your Google Places Listing". Source: http://searchenginewatch.com/article/2327744/Google-Warns-Local-Businesses-You-Have-3-Weeks-to-Save-Your-Places-Listing

I haven't found much other information in the SEO community but I just wanted to see if anyone has actually received this notice or not?

Someone suggested it may just be a test in Australia/Austria. (Not sure which one it is as the comment in the above list references both countries)

Thanks for any information you have on this topic.

You should pick your top 10-20 most important pages on your website & link them from your footer. Since the homepage normally has the most domain authority you want to try to pass along some of the authority to the other pages within your site that you want to rank.

Don't put too many links in the footer as this will over-dilute the home page link juice.
