The keyword density tool is useful for helping webmasters
and SEOs achieve their optimum keyword density for a set of
key terms.
Keyword density is important
because search engines use this information to categorize
a site's theme, and to determine which terms the site is relevant
to. The perfect keyword density will help achieve higher search
engine positions. Keyword density needs to be balanced correctly
(too low and you will not get the optimum benefit, too high
and your page might get flagged for “keyword spamming”).
This tool will analyze your chosen URL and return
a table of keyword density values for one-, two-, or three-word
key terms. In an attempt to mimic the function of search engine
spiders, it will filter out common stop words (since these
will probably be ignored by search engines). It will avoid
filtering out stop words in the middle of a term, however
(for example: “designing with CSS” would go through,
even though “with” is a stop word).
