I gotta stop blogging and do some work… but then Stephen Downes has to share this nifty tool from PubSub– LinkRank:

LinkRanks are our way of measuring the strength, persistence, and vitality of links appearing in sites that syndicate their content. When PubSub reads an entry from a syndication feed, it takes note of any URLs (technically, URIs) it sees. PubSub users can then utilize this link data when creating subscriptions to better express what they’re looking for.

PubSub monitors millions of feeds. By generating a list of all the URLs contained in entries of each feed, it’s possible to determine a site’s relevance just from the number of incoming links it has. LinkRank goes one step further and calculates a score for each linking site. Sites are then scored based on the score of the sites that link to them.

So the CogDogBlog LinkRank gives me a whole raft of data on how is linking to my site:


This looks like the one that will blow the doors off of Technorati, eh?

So I’m even in the same league as Stephen, while yesterday he was in the 5000 LinkRank range, I was stinking it up down in the 20,000+ crowd.

The post "What’s That Smell? Is it My LinkRank?" was originally scraped from the bottom of the pickel barrel at CogDogBlog (http://cogdogblog.com/2005/09/my-linkrank/) on September 30, 2005.

    PubSub linkrank seems a bit volatile, and I’m not sure how accurate it is…

    Check out the oscillations on my nook of the ‘net

    Almost as volatile as BlogShares :-)

  • D’Arcy: Daily LinkRanks are intentionally volatile since that volatility is required to accurately reflect the daily changes in popularity, importance, etc. of sites. This is why we also compute 15/30 (and soon 60) day average LinkRanks. When you average the volatile daily numbers over a period of time, you get a much less volatile number. However, it is important to realize that the daily numbers and the “period based” numbers are telling you different things.
