Technorati Gives Blogs an ‘Authority’ Ranking

Ben has noticed that Technorati have started giving blogs an ‘Authority Rank’. The Top 100 list used to be base upon incoming links but now is based upon ‘authority’ (although I don’t see much has changed in that list so far).

There’s nothing about how they’re coming up with authority rankings yet on their blog – it’ll be interesting to see if this is just a new new name for the old ‘incoming links’ description or if they’re making bigger changes.

PS: It also looks like they’ve changed the way that blog’s profile pages are displayed. I don’t remember how the old ones displayed but here’s ProBlogger’s page. Now with screen shot of the blog, ‘blog reactions’ (what others are saying about the blog) etc.

I also note that they’ve started calling those favoriting a blog ‘fans’ which could indicate some more changes in the favoriting system are under way.

update: More on these changes are now on the Technorati blog

  1. The ‘Authority’ ranking is simply the number of unique blogs that reference yours in a post. It’s not any algorithm or anything.

  2. Yeah its a pity they didn’t boost up the authority system a bit more. Not all links are created equal and a system that gauged blog links by the authority that the incoming blog has and weighted accordingly would be really interesting. Basically a PageRank but just for Blogs!

  3. That must be literally hours old, I was in my profile just a couple hours ago! Well spotted Darren :)

  4. Yeah, I like the new profile page a lot. But by the looks of things, the authority rank is just incoming links all over again because it seems the numbers are the same.

  5. I just cracked the top 5000 yesterday and then today my groovy rank goes away. Now I just have an authority of “559”. Doesn’t look nearly as impressive. :(

    I know. I’m whining on your blog. I’m sorry Darren, I’ll shut up now. :)

  6. I need to work on getting my ranking up. I’m listed on Technorati as http://name and I always link to http://www.name – does this play a role? Should I be changing something in my .htaccess file?

    I would love some advice..

  7. The screenshot of my site is months and months out of date. It’s from at least 2 full make-overs ago. Leave it to Technorati to be slower than a turtle on *everything*.

  8. Ah! I thought I’d done something dicky to my settings! Makes sense now

  9. I just saw this, thought it was some type of ad when I went to Technorati. Couldn’t figure out what I’d done wrong. Left it real fast, glad I went back and came across your blog posting on it. I had noticed lately that things were changing, before when I’d visit I could see my favorites right away, now I must click favorites to get there. Can’t wait to see how this all ends up, not sure if I like it yet but it’ll be neat to watch it.

  10. I like the new changes. I think Technorati makes much more sense now and also looks better!

  11. As Douglas said, they’ve just taken the number of unique blogs linking in and rebranded it to call it “authority”.

    The interesting thing is that authority or rank is not based on the total number of links, but the number of unique blogs that link to you. Which makes sense to slow down the spam potential.

  12. I like the look of the new makeover. It would be nice if they experimented a bit with the authority, for example adding some more parameters to the calculations. I wish links in blogrolls powered by Blogrolling.com would count over at Technorati but that’s a rant for later.

  13. The new profile page format is pretty good; maybe even better than it was before I think.

  14. For all those who’ve read Darren Rowse’s post Five Free Tickets to Future of Online Advertising – First Five Win!, and couldn’t make it through; here’s something to be happy about:

    Ryan, CEO of Carson Systems, on the organising front, has exclusively offered a discount code. Check it out at,

    ‘FOOA discount code is in this blog post’ – http://indiproblogger.blogspot.com/2007/05/fooa-discount-code-is-in-this-blog-post.html

  15. I noticed this earlier today, too. Do you think this is a reaction to the Technorati favorites train that has been going around?

  16. I dont like the new authority thing its annoying but what can you do?

  17. If the authority is based only on links, then they should have done some better calculations. Like taking in account Favorites, or numberof comments… etc.

  18. Well, it would be nice if they’d fix their ping tool before changing to this “authority” thing. There are at least two blogs that link to mine that haven’t been listed for three plus weeks now. I don’t have a very popular blog, it’s a personal site, and it’s not a big deal, but it would be nice if they fixed it. And I’m not the only one complaining about their ping tool. Their latest explanation is that if the blog roll isn’t on the first page it won’t be indexed, which doesn’t apply to my situation, or others.

  19. So many people were gaming the system, Technorati had to do something. I think this is the beginning of them introducing a more complex ranking system, a la PageRank.

    I personally prefer the new Technorati.

  20. Yeah, I noticed that change as well. How far up to the rankings go? I couldn’t find that anywhere on their site.

  21. Wendy, you can click on the link made of your Authority number and still get your Rank. It’s just not as obvious.

  22. […] learned about this over at ProBlogger. Technorati has changed the terminology they use for incoming links, calling it Authority instead. […]

  23. I think ‘authority’ is the wrong word for it.

    One of your posts may do very very well and receive links from everywhere… but that doesn’t really make you an authority in the area. Especially when you consider that the post in question may have nothing at all to do with the theme of your blog.

    Number of oncoming links is still a valid indicator – perhaps it needs to be called “Link Love” or something similarly vague 2.0.

  24. I guess it’s just one more thing I have to delve into and learn. ;)

  25. […] that circulated the net Technorati removed the top 100 favorited list and has instead starting dishing out “authority” ranks. The move is likely the first of many changes that should come to the […]

  26. dont really see much use of it….sounds good though but quite misleading…..besides all its does it gives a number….based on unique links

  27. It looks like they are just making cosmetic changes rather than really upgrading their algorithms or coding, which is a shame.

  30. It’d be nice if they could do include some traffic numbers (Alexa??) / incoming links from popular sites / comments, etc. A formula where authority isn’t simply links from any blog.

  31. IMO, Technorati needs to weigh incoming blog counts by their ‘Authority.’



  32. see http://technorati.com/weblog/2007/05/354.html

    “Technorati Authority is the number of blogs linking to a website in the last six months. The higher the number, the more Technorati Authority the blog has.”

    “It is important to note that we measure the number of blogs, rather than the number of links. So, if a blog links to your blog many times, it still only count as +1 toward your authority. Of course, new links mean the +1 will last another 180 days.”

    Technorati Rank is calculated based on how far you are from the top. The blog with the hightest Technorati Authority is the #1 ranked blog. The smaller your Technorati Rank, the closer you are to the top.

    The Technorati Top 100 shows the most popular 100 blogs based on Technorati Authority. The #1 ranked blog is the blog with the most other distinct blogs linking to it in the last 6 months. If your blog’s rank is, say 305,316, this indicates that there are 305,315 blog ranks separating your blog from the #1 position.
