According to the report, Facebook alone is responsible for a whopping 50 percent of all social sharing. Twitter placed second with 24 percent while Pinterest finished in third with 16 percent. Even LinkedIn beat out Google+ with three percent.
Broken down further, we also see that these three sites are the top sharing destinations among e-commerce and media / publishing outlets. Interestingly enough, however, Pinterest reigns supreme among e-commerce sites followed closely by Facebook.
Marketing Land points out that Google has been confronted with similar data in the past. Their explanation is that most sharing on Google+ happens privately which makes it invisible to data crawlers. That may be true for data collected from other firms but Gigya measures clicks via social tools installed on client sites.
A separate study from SearchMetric concluded that Google+ sharing would overtake Facebook sharing by 2016. That study actually compared two separate metrics: +1 clicks on Google+ against shares on Facebook. Perhaps the better comparison would have been Facebook likes to +1 clicks or Facebook shares to Google+ shares/posts.
