Google+ is now available for business websites
Although Google Buzz is being phased out (and merged with Google+) businesses can now add themselves to Google+
From the Google Blog:
For businesses and brands, Google+ pages help you connect with the customers and fans who love you. Not only can they recommend you with a +1, or add you to a circle to listen long-term. They can actually spend time with your team, face-to-face-to-face. All you need to do is start sharing, and you’ll soon find the super fans and loyal customers that want to say hello.
A number of pages are already available (see below), but any organization will soon be able to join the community at plus.google.com/pages/create.
Direct Connect from Google search
People search on Google billions of times a day, and very often, they’re looking for businesses and brands. Today’s launch of Google+ Pages can help people transform their queries into meaningful connections, so we’re rolling out two ways to add pages to circles from Google search. The first is by including Google+ pages in search results, and the second is a new feature called Direct Connect.
Maybe you’re watching a movie trailer, or you just heard that your favorite band is coming to town. In both cases you want to connect with them right now, and Direct Connect makes it easy—even automatic. Just go to Google and search for [+], followed by the page you’re interested in (like +Angry Birds). We’ll take you to their Google+ page, and if you want, we’ll add them to your circles.
That sounds like a good SEO opportunity to me! HubSpot also do a good write up on Google+ for business and how to add yourself.
