Google is rolling out a new option, called +Post ads Beta, for brands that will allow them to automatically turn Google+ posts into advertisements that can be embedded into sites around the Web.
+Post ads amplify your brand’s content by easily turning Google+ posts into display ads that run across the web. The live, social ad format allows you to go beyond clicks to live conversations with your audience. People can join a Hangout On Air, add a comment, follow your brand or give a +1, right from an ad.
