Q: How often is PageRank updated?

A: There is a distinction between PageRank scores that are updated visibly to us outsiders through the Google Toolbar and PageRank scores that are used within Google’s ranking algorithm. Lately Google has been very spotty with its updating of the PageRank scores on the Toolbar server. In fact, it’s been so spotty over the past 6 months that it’s no longer reliable. Prior to the last update, there wasn’t a major PageRank update in the Toolbar for a stretch of 3 months. In contrast, the PageRank scores used by GoogleĆ¢??s ranking algorithm are certainly updated MUCH more frequently than that.
