Tumblr Reaches 15 Billion Monthly Pageviews

Tumblr Reaches 15 Billion Monthly PageviewsTumblr CEO David Karp revealed new statistics about the blogging platform’s continued growth at this week’s Digital Life Design conference.  Tumblr now has 15 billion impressions monthly and an audience of 120 million people, according this sound clip from The Next Web. The average Tumblr user spends upwards of 30 min on the site each day.

Back in early 2011, impressions were at just 2 billion, showing a remarkable increase in the past year.

Karp focused on Tumblr’s plans for 2012, including a “more deliberate international effort” that will involve “spending more time overseas” and dealing with foreign press.  The majority of Tumblr’s traffic is international, with just 40-45% coming from the US.  Karp spoke of significant growth happening for the platform in both Europe and South America.

Karp also mentioned that 2012 would be a big year for both revenue and product development.
