The quarterly-ish PageRank export is underway. As always, don’t expect traffic or rankings to dramatically change, because these PageRank values are already incorporated into our scoring. The same quarterly-ish data push that updates PageRank in the toolbar also updates the data for related:, link: and info: (remember that operator?). You can read more about PageRank from this previous post if you swing that way. Also remember that the link: operator only shows a subsample of the links to a page that we know of. I’ve mentioned before that some data centers (I believe 64.233.183.xx and 72.14.203.xx) continue to show PageRank values from a slightly older infrastructure. Not a big deal, but I wanted to mention it for the hard-core data center watchers so that they don’t get confused.
