What is keyword density?
Keyword Density Represents the frequency these keyword words appear in a page or in an area of a page. It is a critical issue for search engine ranking-the more often the keyword or phrase appears in a page, the higher its search engine ranking. If repeated too often though, it could lead to the page being penalized for spamming.
Keyword density is a combination of the number of times a keyword or a keyword phrase, in proportion with other words, appears on a Web page. The more times the keyword appears in relation to the total number of on page words, the greater the overall keyword density. The more times that other words appear, the lower the proportion of keywords, resulting in a lighter keyword density.
From Wikipedia: Keyword density is the percentage of words on a web page that match a specified set of keywords. In the context 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.
