when G updates PR, which backlink count does it take into account? the link:yoursite.com or the links archieved in google webmasters?
Google factors in all backlinks - although some may carry little weight. They only show a portion of backlinks using the link command to keep other webmasters from trying to duplicate a top ranking sites links.
Big G recognize the links once is a few months ( uslally 3 ) but he is posting different URL. That is why you see today a link from one site and the other day another one. But if you saw the number is the same. Just my 2 cents
Dude, you completely forgot to factor in the fact that GWB screwed up daylights saving time... those calculations don't work anymore. Also, it looks like you calculated using GMT... you forgot the Google DC's are in Cali, you need GMT -8:00... Fix it, would ya? -Michael
