• 4th column: shows the most important value - the density (%), of keyword inside each element. Background colors indicate spam danger (excessive density), poor density, or acceptable density values.

The "weight" value:

The weight is meant for comparative purposes between different keywords. This way you can establish which keywords have greater relevance, or find out which page is more relevant to some keyword.

A greater "weight" does not necessarily mean that the page is better optimized for search engines, big values of "weight" are unnatural and are signals of spam, on the other hand, very low values of weight indicate poor relevance of the keyword for the page. Use the "weight" value only for comparative purposes and optimize your page based on the density column.
