How often does Google update a site's PR. Is it different for each site? or does Google do them all at one time? I know there was an update last week...
It generally seems to update monthly.
i am currently trying hard to get good links with sites that have a higher pr value than my own, will this higher pr value of theirs rub off on my site?
i have seen some sites with thousands of links on the links page, with a pr of 3? ------is it how many or the quality?
