In theory, each individual search engine has a preferred keyword density, but unfortunately, web pages written to such keyword densities rarely perform well with human beings. Keyword densities are often quoted by those who are overly concerned with on page optimization and who ignore off page optimization through external linking.
Keyword Effectiveness Index (KEI)
A system that attempts to rank the relative popularity and competitiveness of a keyword. A low number is supposed to indicate that a keyword is overly competitive given its traffic. Keyword Effectiveness Index is limited both by its focus on quantitative over qualitative analysis, and the accuracy of search volume data available to users.
Keyword Effectiveness Index is usually abbreviated as KEI.
