The Blogosphere All Summed Up

Dave Sifry, CEO and Founder of Technorati has posted a two part summary of the state of the blogosphere based on what Technorati is currently tracking. Clearly, the statistics and insight show us that the blogosphere is growing at a rapid pace, creating an increasingly powerful expanding network of influence.

Part I:

* Technorati was tracking over 14.2 Million weblogs, and over 1.3 billion links in July 2005

* The blogosphere continues to double about every 5.5 months

* A new blog is created about every second, there are over 80,000 created daily

* About 55% of all blogs are active, and that has remained a consistent statistic for at least a year

* About 13% of all blogs are updated at least weekly

Part II:

* Technorati is tracking about 900,000 blog posts created every day

* That’s about 10.4 blog posts per second, on average

* Median time from posting to inclusion in the Technorati index is under 5 minutes

* Significant increases in posting volume are due to increased mainstream use of easy hosted tools as well as simple posting interfaces like post-from-IM and moblogging tools

* Weekends tend to be slower posting days by about 5-10% of the weekly averages

* During the day, posting tends to peak between the hours of 7AM and noon Pacific time (10AM - 3PM Eastern time)

* Worldwide news events cause ripples through the blogosphere - not only in search volume, but also in posting volume
