Technorati Explains Link Count Criteria: Expiration Date 180 Days

Many of us are still trying to figure out how Google’s Page Rank works, but at least we have a better clue now on how Technorati ranking works through a good explanation by Brian Pinkerton in “Making Sense of Technorati Link Counts”.

We display four count-related numbers in just this little part of the page. Here’s what they mean:

  • Rank 1,375: The number of blogs, plus one, that have more than 1,005 blogs linking to them
  • 1,919 links: The number of links pointing at this URL in the last 180 days
  • 1,005 blogs: The number of distinct blogs pointing at this URL in the last 180 days
  • 3,149 links: The total number of links we found pointing at this blog, ever

In other words, the numbers in the green box reflect activity in the last 180 days, while the number of links directly below the green box is the total for as long as we have data.

The articles goes on to explain how this 180-day window will cause your ranks and link count to change, going up and down based upon your blog’s traffic, links, and activity during those 180 days. Anything past the 180 day expiration date doesn’t impact the next 180 day cycle.

So you have three months of work to get your score up, and three months of consistent “up” to stay up in the ranking at Technorati. Spikes don’t count over time. Interesting.

Google admits that they hang on to historical data for much longer periods of time, comparing domain age and other historical data over the life of your blog with current activity in order to reach their page rank determination. With many blogs dying after 3 months, I can understand Technorati’s decision to stick with a 3 month time period.

    That explains why it looks like the blog backpedals sometimes… so essentially you have to keep your link rate increasing more than it ever did before in order to keep you position.

    It’s a pretty good design for getting a real view of what’s popular. One hit wonders will get flushed out after 3 months.

    That’s fine. But do they take into account links as these that come from the comment section of other blogs?

    anand: only links in the body text are taken in account. IE: links that the blog owner created.

    Links in comments have the rel=”nofollow” tag and are ignored by search engines, Technorati, etc.
