In response to Dr. McLeod’s question on how his survey on the Top EduBlogs can be improved, I had put forward 5 suggestions. You can read them here.
One was that the rankings should reflect blogs that are currently popular, blogs that are fresh. In the same post, I recognised my limited understanding of internet metrics, site ranks etc.
This morning, I decided to read around on Technorati and see that their Authority Rank really meant. Here’s what I found.
On Technorati, only links to you from the last 180 days count towards your authority. So, it does seem that the EduBlog rankings show the fresh, now popular stuff.
It also means that if I want to keep Ms.Teacher or Clay’s Beyond School consistently ahead on the Technorati scoreboard, I need to link to them at least once in 6 months. One link from One Blog = One Authority Point on Technorati.
Before one of you Good Samaritans go on and send several links from your blog towards this one, let me tell you that one blog gets one vote for every other blog. So even if I link to Ms. Cornelius’ Shrewdness of Apes 15 times, she will get only 1 Authority Point.
Another interesting point. Technorati does not distinguish between a ranking from a Top Ranked Blog and a less ranked one. So, a link from Inside Higher Ed (Rank #1) or from Christian’s Think:Lab (Rank # 22) will not count for more than the link from Exhausted Intern’s Not enough Hours (Rank # 569) or Kelly Christopherson’s Educational Discourse (Rank #650), all sites I like to visit (the first two are old bookmarks, the latter two new discoveries I am savouring).
However, Google does make a distinction. Its PageRank alogrithm gives greater weightage to sites with more pages linking to them, so if Christian at Think:Lab were to link to you it would do more to bring your page higher up on Google than if I were to link to you.
That, ladies and gentlemen, was my learning for the day. Hope it gave some of you something new too.
Btw, I encourage you to visit all the links above, they are some of the blogs I enjoy reading.
