If website traffic is important to your brand (and it is to a good many), you may find some new social media metrics will be particularly interesting. Facebook drove 23.4 percent of social referrals on the Web, significantly higher than Pinterest (5.7 percent) and Twitter (1 percent). This research comes from Shareaholic, which studied social referrals from June 2013 to June 2014. The company also found that traffic from Facebook saw a higher increase in share rate (a boost of 14 percent), compared to Pinterest and StumbleUpon, which saw a 2.3 percent increase. Quite a few brands have complained about Facebook’s recent algorithm changes, which seemingly pushes down posts from brands (or doesn’t display them at all), but Shareaholic’s data indicates some robust clicking going on.
