There is a big Google Update going on today. Rankings and Page Rank. Keep an eye on your SERPs and your toolbars.
“I’ve also talked to a few Australian bloggers in the last few days who have noticed significant changes in google.com.au’s results and some UK based publishers who are noticing google.co.uk changes
Personally, I’ve noticed some of my sites see a nice PageRank update, although not EKR.com just yet 🙁
I’ll post anymore findings later as i hear them but WebMasterWorld has a discussion about it. Could this be something big? or just some minor updates.
