The Death of Keyword Density Tools

Keyword Density Analysis:
is complete rubbish - according to Dr Garcia.

this overall ratio [keyword density] tells us nothing about:

1. the relative distance between keywords in documents (proximity)

2. where in a document the terms occur (distribution)
3. the co-citation frequency between terms (co-occurrence)
4. the main theme, topic, and sub-topics (on-topic issues) of the documents

Thus, KD is divorced from content quality, semantics and relevancy.
