Content that is posted to Google+ is far more likely to show up in search results than other pages, websites, articles, and content posted to other social networks because Google ranks their own social network higher and they crawl it faster.
The added benefit is that Google even previews certain Google+ posts with rich snippets (profile picture, media, etc.), giving them even more real estate in a search!

We consider how to integrate Google+ into your overall Google strategy — from SEO and ads to mobile and video —and view it as the social layer that ties all Google-owned properties together.
