Keyword Density in Search Engine Ranking

Definitions of Keyword Density
" The measure of how many times a keyword is repeated compared to the overall content of a web page". For example, If a keyword was listed 5 times out of a word count of 50 the keyword density would be 10%.

In terms of search engine optimization keyword density can be used as a factor in determining whether a web page is relevant to a specified keyword or keyword phrase. Due to the ease of managing keyword density, search engines usually implement other measures of relevancy to prevent unscrupulous webmasters from creating search spam through practices such as keyword stuffing.

The formula to calculate your keyword density on a webpage for SEO purposes is:--
(Nkr / Tkn) * 100.

Where Nkr is how many times you repetead a specific keyword and Tkn the total words in the analyzed text. This will result in a keyword density value.

In general, I recommend using a keyword density ratio in the range of 3-6%.
