As far as I'm concerned, keyword density = red herring
I've just been looking carefully at a site that has leapfrogged me over night for a 2 word term. Their KW density on the page overall is slightly higher than mine but in link anchor text they have half as many repeats and and half the density of my pages on page anchor text. Could link anchor text KW density be an issue?
The specific page has about 20% more external links than me but 50 times as many internal links. 70 vs 3500. For the domain as a whole they have about 160 more linking root domains but 50 times as many backlinks.
In our niche I just don't understand where they have managed to buy hundreds of thousands of links and got away with it.
