PubSub (profile) has been experimenting with blog stats recently (see their pubstats page). Zachary Rodgers reported earlier today that PubSub has released it’s newest stats tool – a list of the top 1,000 most influential blogs.
The PubSub LinkRanks 1000 is a list of the most consistently influential sites that publish feeds, based on their average LinkRank scores over the past 30 days. To create this list, we’ve averaged the daily LinkRanks of over 16 million sources. We’ve also included a 15-day average as well as each site’s current LinkRank as additional points of comparison.
PubSub also says “LinkRanks is PubSub’s method of measuring the strength, persistence, and vitality of links appearing in over 16 million sources that PubSub monitors.”
Robert Scoble says “Ahh, more fun with blog search ahead!”
The lists includes 15 and 30 day trailing data for each blog, current rank and percentile and a link to site stats (example – techcrunch).
I’m skeptical of the data from PubSub but quite frankly I’m skeptical of the data from its competitors such as Technorati, BlogPulse, Blogsares, Feester etc. etc.
It seems that each of them picks up some incoming links but not others. If you did a composite of seven or eight of these services, you might get a better picture of the actual number of incoming links. However, even then, any purely mechanical technique for ranking blogs seems subject to a variety of errors that no current algorithms are going to solve.
This is my “seat of the pants” opinion based on my experiences with them. But I bet that a lot of bloggers share my opinion.
Agree 100%. There is no such things as an error-free or completely objective list.
I agree with Bruce. These services are spotty at best. I’ve had blogs that have had 5 articles a day replete with links, but pubsub never even noticed outgoing or incoming links for several days.
