Google has published updated public page ranks in a surprise move. Earlier this year Google Guy (Matt Cutts) had said he would be surprised if Google updated the public PageRank data before 2014.
Initial reports seem to be that people are seeing more drops in PageRanks than increases – but that could just be a factor of who is talking the loudest. Also there is more speculation that the data is old. In a quick check of 2 high PageRank blogs of mine the latest posts with PageRank are in August – no September, October, November or December posts have page rank (it may well be within a few days of September 1st in either direction). In past updates the data would often be 2 weeks old, this indicates it may well be over 3 months old (which others are also saying).
The previous update was in February 2012. In the past the updates have been published at about 3 month intervals but with a fair amount of variation.
It is unlikely they will publish new values 4 times in 2014, but we will have to see.
