Today 25 Jan a change is happening again here with my sites. First- the bad news is that backlinks number has decreased in times.In all the sites I monitor. From 115 to 20. From 76 to 12 and etc. And this happened not more than three weeks after they have moved up nicely. PR has changed as well. Good news is one of my PR0 is finally jumped to PR3.Also on my other sites inner pages have gained PR which i suppose is good after all.Isn't the January change over? What's going on Google?
