I'm trying to determine the amount/importance of high PR back links so I want to know what you guys would think would happen in this scenario. I know there are many other factors, but please just make a guess. Scenario: My PR 1 site ranks on the 3rd page for a medium competition keyword. In one week I get 10 x PR 2 backlinks and 5 x PR 3 backlinks all on the homepage with no other outbound links. Do you think my site would then make it to the first page?
