In a post on the official AdWords blog, Google has announced several new advertising capabilities on Google+. The company is expanding the availability of its+Post ads, in addition to introducing promoted Hangouts on Air and automatic post promotion. For those unfamiliar, +Post ads allow brands to turn Google+ content into display ads.
Starting today, the +Post ads are now available to a handful of new advertisers. Assuming you have a Google+ page with at least 1,000 followers, are using a post with content relevant to your audience, and have opted in to sharing endorsements for Google+ pages, you can now take advantage of +Post ads.
Google+ also now supports promoting Hangouts on Air with +Post ads. These promotional posts let users take specific actions before, during, and after a Hangout. Users can RSVP prior to the Hangout, watch the broadcast live, and view a recording after the event directly from the promoted post.
Finally, you can also now promote your most recent Google+ post and pay for it only when people engage with your content.
