Plenty of people have Google+ accounts, but do many people actually use them for being social? Marketing Land reports that online brand management firm Gigya has released new data showing that Google’s social network only accounts for 2% of all social sharing across the web. Facebook is unsurprisingly still the top network for sharing, accounting for half of all content shared across the Internet. Twitter and Pinterest also account for significant portions of shared content, respectively accounting for 24% and 16% of social sharing. The most embarrassing part for Google, though, is that LinkedIn is actually beating Google+ for shared content with a 3% share, meaning that Google+ users share even less than users of a website that is mostly used for business networking.
