Second PageRank Update this month.
Second PageRank Update in January
After the PageRank update earlier this month, on the 10th January, nobody expected another PageRank update for another 100 days or so. However, there was an update today that saw hundreds of internal pages lose PageRank throughout the web - leaving a lot of disgruntled webmasters!
It seems to have happened as a result of Google changing their algorithm to reduce the effect of Googlebombing, which also happened today.
It remains to be seen what the fallout will be following this PR update, or if Google intend to go back to updating toolbar PR and their backlinks on a more regular basis.
