Google’s Christian Oestlien announced on Google+ that you can now use Google AdWords Express to advertise your Google+ page in Google.

You can do so when you see an “Advertise” link on your Google+ page. It uses AdWords Express to create and place the ads for your Google+ page. Christian explains that once you enable it, it will:

Attract new customers and followers with ads that run across Google (on Search and Maps, for instance), and across the web (on the Google Display Network)
Will only show these promotions when they’re appropriate – not overwhelming people with random ads when they’re trying to spend time with friends

Here are some pictures:

Note, this is currently available to US customers but will be rolling out more broadly soon.
