Cross-posting has become a way for marketers to scale their social media presences by leveraging the content from one platform and reposting it elsewhere. It's become clear that this is the case for many brands with a Google+, in particular. You don't need to spend too much time to realize that many brand Google+ pages feature duplicate content from Facebook and Twitter presences. Why? Too many marketers do not understand Google+ but feel the need to be present because of the myth that Google+ brand pages have a direct impact on SEO.
