My site is pretty new. it launched it on 17 Jan 2006. thank God my site is not facing any said problems like "Sandbox effect". Since last one week i can see that google toolbar dispaying PR4 For my site and also for internel pages.but it is still dancing.means last night it was 4 today it is 2.friday it was zero!. it shows PR 5 For Directory submission page.PR 3 For My directory.How many days it will happen? I know seo properly but this PR Dancing is new for me. Another strange for me is last night i was checking my PR.I Have two browsers both IE's and Mozilla Firebox but My pr was Zero for Mozilla and for IE it was 4!!.How is it possible? #Mega Directory Submission Submit Your site to about 255+ top Free Web Directories.improve your SE Ranking! #200+ Powerful Scripts for website Let We Find Link Partners for you!!
Okay, the sandbox effect, is very real for any new site in a competitive niche The PR fluxing is because they are in the middle of doing an update/completing an update. So you are probably just seeing different data from different DC's. It will even out eventually. Brad
My older sites are stable like a rock...but my newer sites are doing this too and have done it in the past until the PR update was done. I'd give it a week.
I had the same thing with some of my sites. One day pr5, other day pr3 again. Very strange. Now it's still going on for already 3 weeks and strangely enough i have more computers at more locations. Each computer gives a different result.
