StumbleUpon Drives More Than 50% of Social Media Traffic [STATS]

[wp_scm_mashable_stumbleupon]

Which social media site drives the most traffic to the rest of the web? If you think it's Facebook or Twitter, you're wrong. StumbleUpon now accounts for more than 50% of all referral traffic from the top social media sites.

New data from StatCounter shows that StumbleUpon is the dominant source of traffic among the world's top social media sites. For the first 18 days of August, StumbleUpon accounted for 50.27% of all referral traffic from the top 10 social sites. Facebook was second with a 38.9% market share, while Reddit, YouTube and Twitter each garnered less than 4%.

The stats are surprising, to say the least. StumbleUpon has been growing rapidly (it recently surpassed 25 billion clicks of the StumbleUpon button), but it has nowhere near as many users as Facebook or Twitter. The company does track approximately 3 million websites, however, so it has a decent sample size.

While we hesitate to say StumbleUpon drives more traffic than Facebook (can 12 million users really beat 750 million?), the service is clearly growing in influence.
