Since the initial launch of Google+ just a few months ago, the network has reportedly seen over 40 million people and introduced more than 100 new features. What was missing has been a Google+ page for brands and businesses, which Google launches today. You can sign up for a Google+ page for your business here.

A number of pages are already available, and the service will be slowly rolled out to enterprises worldwide. Check out the page for Angry Birds, Macy’s, or the Barcelona Football Club. You may also want to take a look at the Google+ page.

Google is also bringing the ‘+1’ back to Search. When searching for a major brand, company, or cultural entity, try placing a ‘+’ in front of your query. For example, if you searched for the query ‘+youtube’ or ‘+pepsi,’ you could be taken to the YouTube Google+ page, or the Pepsi Google+ page, and given the option to add the page to your circles, via a service called Google+ Direct Connect from now on.

Vic Gundotra (Senior vice president, Engineering, Google): We want to make sure you can build relationships with all the things you care about.
