The average visitor to Facebook's mobile site or app spends roughly 49 minutes there a day, according to comScore. This means that Facebook accounts for about a third of all the time people spend visiting social media networks on mobile.
Every month Cowen and Company tracks metrics for the social media apps it covers, including Facebook, Instagram, Twitter (TWTR), Pinterest, Yahoo! (YHOO)-owned Tumblr, LinkedIn (LNKD), Snapchat and Tinder. This social universe as a whole saw good growth in April, with the total mobile app unique visitors increasing 1% month over month, but Facebook saw stellar growth.
Menlo Park, Calif.-based Facebook added 3.4 million unique visitors in April, and Instagram, which Facebook owns,, added 3.8 million unique visitors.
LinkedIn showed the strongest growth of unique visitors in terms of percentage, increasing 26% over March. Snapchat grew 10%, Tumblr grew 9%, Twitter and Pinterest each grew 7%, and Tinder grew 5%.
Facebook also led the pack in terms of engagement with its app. Of the 49 minutes a day users spend on Facebook's site and app, 44 minutes of those are on the app, a 55% increase year over year and an 8% increase month over month. This marks a new high since Cowen started tracking in December 2012.
