Google Page rank update is going on. I saw my site's home page page rank improving from zero to three . what about you?
Don't get excited man...PR has just updated on 27th June and until 3 months no possibility of updating. May be your site having temporary fluctuation.
what other tools are you referring to? did all of your site received an update? increase or decrease?
I really doubt there are any updates going on, (but I could be wrong). What you are seen is probably some minor fluctuation corrections. They don't normally do updates that soon. My guess is that it is just a small 'tweak'. FFMG
my pr is now 1 from 0 lol, im not sure when did this happen, i haven't updated my blog for almost a month now
Google does minor adjustments between major PR updates. These are not the big, global PR updates like we saw in June and January. They affect recently penalized sites, newly registered sites, sites that have changes hands or sites that have experienced some other major change. I suspect Google's reasoning for the minor updates is to shut people up about "why did my site go down" or "when will my site go up". This would be consistent with why Google keeps PR public at all.
my website page ranks 1 domain : 0 to 5 pr 2nd domain : 0 to 6 pr 3rd domain : 6 to 4 4th domain : unchanged (4)
