Following up on RSS Readers: Narrowing Down Your Choices and Danny Ayers’s post on blogging hosts — here’s our attempt at ranking blog hosting websites. These statistics are based on Technorati’s index. Software used (MT, WordPress etc.) are not part of the statistic.
Technorati API allows 500 queries per day. We picked query words randomly from an english dictionary. We then collected the top 100 results (most live blogs) between 9:00 AM and 1:00 PM EST over a period of the last 18 days. We eliminated duplicate blog home pages to create a list of 173192 unique blogs.
Note: Technorati ranks results by freshness — our statistics are hence for the “Live Blogosphere”.
We do not claim our statistics to be representative. These are the biases —
- Technorati index.
- US Blogs, given our query time-frame.
- Blogger — spam blogs are very live.
- Self hosted blogs. Our numbers only use URLs to classify blogs. For instance, a blogger weblog hosted at a personal website is not classified with blogger. Blogger blog’s are identified by “blogspot.com” being part of the URL.
Even with these biases, our numbers should give a good estimate of blogging host popularity.
Based on our collection here’s how blog hosts compare.
Technorati API also provides inlink information of blogs. We normalized inlink for these blog hosts to find the the number of inlinks/blog for each of these hosts. Total inbound links in our collection is 1.8 Million. The mean inlink/blog is 10.64
The impact rating – inlinks/blog
The Rest .. includes many blogs which are self-hosted. Self-hosted blogs, as is evident are the most popular.
Thanks to Jim Mayfield for suggesting the use of technorati.
