In conjunction with the recent website re-design, it would be fruitful to give the Google+ badge more prominent placement. This allows users to easily follow your Google+ page directly from the website.
Direct Connect is an interesting search tie-in that enables users to automatically add brands to their Circles by including the plus symbol (+) before a brand name in their Google search queries. Similar to call-outs in advertising that ask consumers to “Like us on Facebook,” you can say, “Search for +YourWebsite on Google,” and the action will take users directly to your Google+ page. This functionality is available for many, but not all, so maybe you can suggest an article be written on the topic and then use it to encourage locating your Google+ page this way.
