Two new reports from Shareaholic, a leading content sharing web tool development company, finds that Facebook far outpaces other social media sites when it comes to driving traffic to websites but YouTube is #1 for driving the most engaged traffic.

The 1st Quarter 2014 edition of the Shareaholic Social Media Traffic Report is based on data collected from more than 300,000 websites and examines eight social media platforms referred to those websites from December 2013 through March 2014.  Here are the findings:

Key takeaways from this report:

• Facebook drove almost one-quarter (21.25%) of the overall traffic websites received in March.  Clearly, Facebook users have made it a habit to click on links in their feeds, so marketers should be sure to include those in their posts.

• Pinterest’s share of traffic referrals grew an astounding 48% from December to March, making it the second largest referrer.

• The lowest ranked referrer sites were YouTube, Google+ and LinkedIn.

While social site referrals help marketers when it comes to organic traffic, it is also important for marketers to factor in engagement – what people do on your site once they reach it.  And anotherShareaholic study shows an almost inverted hierarchy for social media sites that provide engaged social referrals:

YouTube is the champion when it comes to driving the most engaged traffic back to your website.  Google+ and LinkedIn also rank high for bringing engaged traffic – the people most likely to stay on your site after they reach it via these social media sites.
