With over 1.3 billion monthly active users and being the world’s largest social network, it’s not surprising that Facebook drives more social referrals than its rivals.

Interestingly, the discrepancy in traffic rates from different social networks is staggering, as Facebook leads the pack by a wide margin. According to a new report from Shareaholic, the social titan drove 4 times more referral traffic than Pinterest, the second biggest source of social referrals.

The report also shows that Facebook now drives more than a fifth of overall traffic, which includes direct traffic, paid search, organic search, social referrals, etc.

For this report, Shareaholic aggregates data of more than 200,000 websites around the world between September 2013 and September 2014 to see how much traffic they receive from the eight most popular social networks: Facebook, Pinterest, Twitter, StumbleUpon, Reddit, Google Plus, YouTube and LinkedIn.

“Driving 22.63% of overall traffic to sites, Facebook’s share of traffic has exploded in the last year. Since September 2013, its share has increased 115.63% (11.99 percentage points) from 10.37%,” the report reads.

Despite Facebook’s firm foothold, Pinterest is slowly catching up with a 50.07% growth in its share of traffic over the past year. The visual discovery platform delivered 5.52% of total visits to those sites, giving it a significant edge over Twitter whose share has steadily declined by 0.29 percentage points (down 24.97%).

The remaining five social networks are touted as “forgettable sources” of referral traffic for most publishers, site owners and marketers. While Google Plus saw modest gains, YouTube lost big time, shedding over 80% of its weight.
