Hi, I have one PR6 link pointing to one of my sites. I was wondering, how many more PR6's do I need to get a PR7, 8, 9 or 10? Thanks
To do a mathematical estimate you would need to know how many other outgoing link are on the pr6 site. Also a pr6 + a PR1 does not make PR 7 this is why no one will give you an exact answer. But if there was only one outgoing link on the page you divide the pr by .85 roughly And i would say at a guess 2 PR 6 link should put you to PR7.
this wont be a easy calculation and noone also know that on the next update if google will follow the same alog so just keep building links and see what happns.
