I consider myself lucky to maintain a Technorati Authority of 76 to 80 for the OakLeaf Systems blog. (It once hit a high of 130 when I posted a controversial topic.)
So I was surprised when I accidentally clicked on Technorati’s synopsis of a recent post about the Entity Framework by Microsoft UK’s Mike Ormond, as shown here:
I didn’t notice the Authority rating of either entry for Mike’s post in the preceding blurbs, but I did when I saw Mike’s rated #8 out of the approximately 2,000,000 blogs Technorati spiders, as shown here:
To give you an idea of some technology blogs competing in this authority range, TechCrunch is #2 with an authority of 22,152 and Gizmodo is #3 with an authority of 21,123. Scott Guthrie (ScottGu) ranks 739 with an authority of 1,855 (but his posting frequency has dropped considerably in the last month or so).
That’s not to say Mike’s blog isn’t great; it’s on my Feeds list to check every four hours.
However, Mike says its real Authority is
39 83 (see comment). The point is that rating a group blogsite (e.g., http://blogs.msdn.com) by the sum of its members authorities is nuts.
Issue: The preceding links appear to appear and disappear randomly and for no apparent reason. Several of my recent posts with Entity Framework tags still don’t appear in the list and the Entity Framework post frequency today is obviously incorrect:
I posted at least 10 items with an Entity+Framework tag during the period 8/20/2008 and 9/10/2008. It appears that Technorati was encountering spidering problems before their initial outage in August.
Note: My A Suggestion for Technorati's Blog Authority Ranking Algorithm post of 5/8/2007 suggests an improvement for Technorati’s ranking algorithm. However, it would make better sense for Technorati to concentrate on consistently listing new posts by tag and eliminating aggregate ranking of group blogsites before considering a more accurate ranking algorithm.
