Tumblr CEO David Karp revealed the statistics in Munich this week at the Digital Life Design conference, where he also discussed goals for 2012 regarding product development, revenue and staff size (see audio clip below).
Last time Tumblr unleashed figures was in September when monthly pageviews hovered around 13 billion, up from 2 billion at the beginning of 2011, reflecting a 218% year-over-year increase.
To put the stats into perspective, WordPress.com blogs attract roughly 316 million people internationally who view 2.5 billion pages each month, while Reddit's almost 35 million monthly unique visitors check out 2 billion pages. Facebook reportedly surpassed 1 trillion monthly pageviews in in mid-2011.
When looking at U.S. stats alone, however, WordPress.com sites trumped Tumblr blogs on average each month in 2011: 20.4 million vs. 10.9 million pageviews.
Tumblr, which launched in 2007, wants to give a "much more deliberate international effort" in reaching the audience outside of the U.S. in 2012, Karp says in the SoundCloud clip below from The Next Web. To accomplish this, Karp says Tumblr will spend more time with the foreign press and pay more attention to local markets. Right now, about 40% to 45% of Tumblr's users reside in the U.S.
Karp also says 2012 will be a "big year for revenue development products," meaning several experimental initiatives from last year will soon become "full-blown products." We've reached out to Tumblr's press folks to elaborate on these products and will update this post accordingly once they respond.
Expanding Tumblr's staff -- which grew from 15 members to 70 last year -- is another major goal for Karp.
