Understanding Keyword Density:
Keywords density is the percentage of keyword or phrase appearing on a particular page of your website as compared to the total numbers of words used. In terms of SEO, keyword density can be used as a tool in determining whether the page is relevant to the keyword or not. It will also help in determining that you are not over optimizing your web page. For example: You have 500 words article and you have used your keyword 20 times, this means that your keyword density in the article is 4%.
Density = ( Nkr / Tkn ) * 100.
Nkr (frequency) is how many times you repeated a specific keyword and TKr is the total number of words in the text.
According to many SEO experts the best Keyword density is 1 percent. To get better results from your SEO campaigns it is very important to maintain the optimum keyword density. If you do keyword stuffing in your web page then your website can get penalized by Google.
