I have been comparing back-links for the top 10 sites for many hard to rank key phrases.
It looks like sites with less links or no links to their inner pages rank in the top 3 some have no links some have 5
links keywords spread around.
On the average 3 good links does it.
Home page is different just keep it under 5% for your keyword and make sure your brand name is higher %.
Also with this formula you will lose some rankings on Yahoo and Bing.
