State of the Blogosphere, October 2004

Things have been incredibly busy over at the day job, so it is nice every once in a while to take a step back and look at the big picture. To prepare for my presentation at last week's Web 2.0, my team ran a number of analyses on the collected data that we've been tracking since November 2002, when the Technorati service started, and we've noted a number of interesting trends over the past 2 years, so I thought I'd take some time out this week and blog about each one of them, accompanied by some charts and graphs showing the underlying data.

First off, let's look at the size of the blogosphere (click on the picture for a larger version):


First off, we're now tracking over 4 Million weblogs. Regular readers will remember that we tracked the 3 Millionth weblog on July 7th, just 3 months ago. In addition, the blogosphere has been doubling at a regular pace, and it is now more than 8 times as large as it was in June of 2003. In addition, the slowest rate at which the blogosphere has doubled in size is once every 5 months.

This leads to the second graph, which shows the acceleration of the growth of the blogosphere:


This shows the number of new weblogs being created every day. Right now, there are about 12,000 new weblogs being created each day, which means that on average, a new weblog is created every 7.4 seconds. It is important to understand, though, that not all weblogs are regularly posted to - in fact, about 45% of all older weblogs have not had a post in 3 months. This may be due to abandonment, hosting service switches, tire kicking, or other factors, Mary Hodder has a good discussion on these issues.

Tomorrow: Volume of posts, and what it can tell us about ourselves...

This is great information to have. I'd love to also see market share numbers for the various weblog publishing and aggregation software and services vendors. Technorati seems to be well-positioned to be the Netcraft of the blogosphere. Keep up the great work.

Can I get a clarification. Isn't the 12k/day number, the number of blogs added to Technorati and not the number of actual new blogs? I think the growth is much higher than the 12k/day you are reporting.

The bump in the number of blogs created during the summer is interesting... I wonder if it's due to massive news coverage about blogging during the political conventions? Or is it lots of students with nothing to do during summer break except blog?

Also, is there any way to track the number of _bloggers_ rather than the number of blogs? Some people start and stop new blogs, while other blogs might be news sites with RSS feeds? (unless you're able to differentiate between blogs and more general websites with RSS feeds...)

How are you telling the difference between blogs and non-blogs? There are plenty of sites in the Technorati index that aren't blogs - newspapers, for example. Are these counted in your figures above? If not, is 12k just a measure of the number of new URLs referenced within the sample set, and not a meaningful measure of blogs at all?
