Google has updated page rank in December 2013
According to Matt Cutts from Google he said he would be surprised if there was a public update in Google page rank before 2014, but it has happened.
Many lower quality websites and blogs have lost their page rank altogether . However as always there have been winners and losers.
Page rank now has less of an effect on rankings but it does effect the crawl rate that google comes to visit your website.
Many SEO’s will be rushing to check their page rank, but the public displayed page rank update has been preceded by Google internal updates which occur on a much more frequent basis.
Most SEO’s now agree that Domain Authority and Page Authority is a much better indicator of rankings of domains and individual pages.
