Keyword Density (calculated as percentage) is a keyword or phrase appearing on a web page compared to the total number of words on the page. With the perspective 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.
Earlier keyword density was an important factor in how a page was ranked. But with the discovery of webmasters the implementation of optimum keyword density became widespread. It became a minor factor in the ranking. But, nowadays the overuse of keywords (also called as keyword stuffing) will cause a web page to be penalized.
Formula to calculate keyword density on a web page for SEO purposes:
(Nkr / Tkn) * 100
Nkr is equal to number of times a specific keyword is repeated.
Tkn is equal to total words in the analyzed text.
Formula to calculate keyword phrase on a web page for SEO purposes :
(Nkr * Nwp / Tkn) * 100
Nwp is equal to number of words in the phrase
Example: Suppose for a page about search engine optimization where that phrase is used five times and there are three hundred words on the page, the keyword phrase density is (4*3/300)*100 or 5 percent.
Keyword density is important because search engines use this information to categorize a website's theme. This also determines which terms the site is relevant to. The perfect keyword density would help in achieving higher search enginepositions. Keyword density should be balanced correctly.
