Facebook Makes Up 52% of Sharing on the Web

AddThis is used by more than 11 million sites, which gives it aggregate sharing data for more than 1.2 billion users — and a bird’s-eye view of the relative popularity and influence of everything from a Facebook Like to a click on a Google +1 button.

Below are some key findings from its year-end look at social-sharing trends:

- Facebook accounts for 52.1% of sharing. Given the size of AddThis’ data set, that number’s probably a solid proxy for sharing across the entire web.
- Twitter was up 577% this year and accounts for 13.5% of sharing
- Usage of Google’s +1 button grew in 2011 but has plateaued.
