PubSub LinkRanks Measures Blogs, Links, and RSS Feeds
PubSub today announced the release of LinkRanks, which PubSub dubs”the Blogosphere’s most comprehensive tool for tracking the popularity and influence of blogs and websites”. LinkRanks provides detailed data that bloggers and feed publishers can use to actively monitor the results of their publishing efforts, and gain insight into how to improve their future rank and influence.
PubSub LinkRanks measures the strength, persistence, and vitality of links appearing in the more than 16 million web feeds monitored by PubSub. PubSub has also made available the PubSub LinkRanks 1000, a list of the most consistently influential sites that publish feeds, based on their average LinkRank scores during the past 30 days (hey that’s 500 more than the Feedster 500 and actually based on Science!).
“Unlike other ranking systems, PubSub LinkRanks does more than just show you which sites are influential today, we also show which sites have had influence over the last 15 and 30 days. This multi-period ranking approach is something quite new and we’re very pleased with the insight it provides,” said Bob Wyman, CTO and co-founder of PubSub Concepts, Inc. “PubSub LinkRanks is an essential tool for people looking for an accurate way to measure how well their messages are propagating over time, or for companies looking to keep a pulse on their standing in the market.”
More from PubSub on how LinkRanks works : PubSub monitors over 16 million web feeds daily. Each day’s LinkRanks are based on a careful algorithmic analysis of the 16 million links that are found in those feeds on an average day. Individual links are given different values based on the LinkRank of their source, the age of the links, and the number of links created by any one site on a day. Once all the sites that are linked to on a given day have been ranked in numerical order, they are also divided into percentages. Thus, it is easy to see if a site is in the “Top 1%” or in the “Top 75%”. PubSub users can use these percentages to tune their subscriptions, and to filter out results from sites whose LinkRank is below a certain threshold. You can, for instance, ask to be notified of blogs that mention some keyword – but only if the LinkRank for each blog is in the “Top 5%”.
Not all sites will have a LinkRank. If a site hasn’t published in the last 30 days or its feed isn’t read by PubSub, it won’t be considered during the LinkRank calculation.
