Shareaholic have released some really interesting statistics that show the amount of traffic websites get from each of the social networks, as a share of total traffic. There are several interesting tables and graphs so I recommend a look at their page.
The most interesting to me was the table below it shows Facebook's continuing rise and (amazingly) Twitters decline. It also shows just how little traffic is generated by Linkedin and G+.
3. Twitter is losing influence and clout On a mission to be more like Facebook, Twitter may have lost its way. Since September 2013, Twitter’s share has steadily declined from 1.17% (its 13-month high) to 0.88% (its 13-month low) last month. This is a loss of 0.29 percentage points (down 24.97%).
