We don't just look at links, we examine the area around a link.
If a link is alone in a paragraph of text (editorial), it will have a LOW Link Density, and appear towards the left of the chart.
A link that appears with a long list of other links (a directory, or navigation) will have a HIGH Link Density. It will appear towards the right of the chart.
